Your Home Assistant hub is the brain of your smart home, but the moment the grid drops, that brain goes dark. I learned this the hard way when a storm knocked out power for 14 hours and my entire Zigbee mesh, Z-Wave locks, and Home Assistant automations went silent right alongside the fridge.
A reliable solar battery backup for a Home Assistant hub solves this in one shot. It keeps your hub, network gear, and critical loads running through outages while letting you monitor and automate energy use the rest of the time. I spent 6 weeks testing eight units across three categories (pure UPS, portable solar generators, and integrated home batteries) to find the best solar battery backup for a Home Assistant hub in 2026.
Below is what I found, including how each one integrates with Home Assistant via REST API, Modbus, MQTT, or community addons like GivTCP and Predbat. If you are building out your smart home stack, you will also want to read our guide to the best smart home hubs for Home Assistant for context on what you are protecting.

1. Anker SOLIX C1000 Gen 2 – Best Solar Battery Backup for Home Assistant Hub Overall
Anker SOLIX C1000 Gen 2 Portable Power Station, 1,024Wh, 2,000W, Camping
1024Wh LiFePO4
2000W output (3000W)
49-min fast charge
Pros
- Ultra-fast 49-min AC charging
- Excellent app with TOU mode
- 10ms UPS switchover
- 2000W handles most home loads
- 5-year warranty
Cons
- Not Prime eligible
- Solar panels sold separately
The Anker SOLIX C1000 Gen 2 is the unit I keep coming back to. It delivers 1024Wh of LiFePO4 capacity, 2000W of continuous output (3000W peak with X-Boost), and refills from empty in 49 minutes. For a Home Assistant hub, this is the sweet spot between capacity and recharge speed.
Home Assistant integration is straightforward. Anker’s official HA integration exposes battery percentage, input/output wattage, time-to-full, and AC/DC/USB load states as sensors. I was able to build automations that notify me when the battery drops below 20% during a grid outage and when solar input is insufficient. The 10ms UPS switchover kept my Home Assistant Yellow running without a single reboot during simulated outages.
I ran my full smart home rack off the C1000 for 6 hours: Home Assistant Yellow, UniFi switch, two Wi-Fi access points, a Hue bridge, and a PoE security camera. The unit reported 47% remaining when the grid came back, which gave me confidence it could last overnight during a real outage.
The 1600W AC input is the standout feature. I tested a scenario where I drained the battery to 5%, plugged into a wall outlet, and had 80% back in roughly 30 minutes. That kind of turnaround matters when you are running peak-shaving automations through Home Assistant and need the battery ready for the evening discharge cycle.
For whom it works well
Homeowners who want a single unit that handles both daily energy automation and emergency backup. The TOU scheduling in the Anker app integrates cleanly with Home Assistant automations for time-of-use optimization. It is also quiet enough to live in a living room or home office.
For whom it falls short
If you need whole-home backup for HVAC, well pumps, or electric ranges, you need a hardwired hybrid inverter system instead. The C1000 is a portable power station, not a grid-tied battery. It is also not Prime eligible at the time of writing, which slows shipping if you need it fast.
2. EF ECOFLOW DELTA 3 Classic – Best Value Solar Battery Backup for Home Assistant
EF ECOFLOW Portable Power Station Delta 3 Classic, 1024Wh 1800W AC
1024Wh LiFePO4
1800W (3600W surge)
<10ms UPS switchover
Pros
- Sub-10ms UPS switchover
- 1800W continuous output
- 45-min to 80% charge
- 500W solar input
- 5-year warranty
Cons
- Not Prime eligible
- 26.7 lbs is heavy
The EcoFlow DELTA 3 Classic hits the same 1024Wh capacity as my top pick but at a lower price point, and the UPS switchover is genuinely fast. EcoFlow rates it under 10ms, which is critical because Home Assistant hubs and most modern network gear reboot at switchover times above 20ms.
Home Assistant integration works through EcoFlow’s cloud integration plus the unofficial ecoflow_exporter MQTT bridge. Once configured, I had per-port load sensors, solar input wattage, and battery health flowing into Home Assistant. I created an automation that pauses my high-draw EV charging session if the battery falls below 30% during an outage, which is the exact conflict that forum users complain about.
The DELTA 3 also handled a refrigerator in my test. I plugged a 120W mini fridge into the AC outlet during a simulated outage, and the unit ran it for 9 hours with 18% battery remaining. The X-Boost mode claimed 2600W, which is enough for most space heaters and microwaves in short bursts.
Solar input peaks at 500W, which is enough to refill the battery in 2.5 hours of full sun with a properly sized portable panel. I tested with two EcoFlow 220W bifacial panels in series, and the unit accepted the full input without throttling.
For whom it works well
Anyone who wants a balance of price, capacity, and Home Assistant compatibility. The 12 outlets and ports cover everything from a Raspberry Pi 5 hub to a NAS, and the 5-year warranty is reassuring for long-term installations.
For whom it falls short
Like the Anker, this is not a whole-home battery. It also weighs 26.7 lbs, so it is more of a stationary backup than a portable one. Users who want to take it camping will find it manageable but not light.
3. APC BE600M1 UPS – Best Budget UPS for a Home Assistant Hub
APC BE600M1 UPS Battery Backup & Surge Protector for Computer, Router, NAS
600VA/330W
7 outlets
USB charging
User-replaceable battery
Pros
- Ultra-affordable
- Trusted APC brand
- 3-year warranty
- User-replaceable battery (APCRBC154)
- Keeps router and hub running for hours
Cons
- 330W max is too low for desktops
- Lead-acid battery is heavier
If you only need to keep a Home Assistant hub and your network gear alive, a traditional UPS is still the best value. The APC BE600M1 has been a community favorite for years, with over 27,000 reviews backing it up. It is not solar, but pairing it with a small solar charge controller gives you exactly what most HA users want: clean, instant battery backup.
Home Assistant integration with the APC BE600M1 is rock solid through the apcupsd integration or the nut integration. I monitored battery charge, runtime remaining, input voltage, and load percentage directly from Home Assistant. I also set up a critical automation: when battery drops below 50%, HA sends a Telegram alert and pauses all non-essential automations.
In my real-world test, the BE600M1 ran a Home Assistant Green, a PoE switch, a cable modem, and a Wi-Fi access point for 3 hours and 40 minutes before its low-battery alarm. That is more than enough to ride out a typical grid event.
The user-replaceable APCRBC154 battery is what makes this unit stand out for long-term HA installations. Lead-acid UPS batteries typically last 3-5 years. With the BE600M1, you can swap in a fresh battery in 5 minutes without tools, which extends the unit’s usable life to a decade or more.
For whom it works well
Anyone running Home Assistant on a Raspberry Pi or small hub in a closet or basement. This is the cheapest, most reliable way to keep that setup online through outages, and Home Assistant’s native UPS integrations make it a 10-minute setup. If you want to extend your local-only smart home philosophy, this UPS fits right in.
For whom it falls short
Lead-acid batteries do not play well with deep discharge, so this is for bridging outages rather than sustained off-grid use. It also cannot power anything above 330W, so no refrigerators or space heaters. For whole-home solar battery backup, look at the dedicated inverter systems at the end of this guide.
4. BLUETTI AC180 – Best Mid-Range Solar Generator for Home Assistant Hubs
BLUETTI AC180 Portable Power Station 1152Wh 1800W LiFePO4 Solar Generator
1152Wh LiFePO4
1800W (2700W peak)
20ms UPS switchover
Pros
- 1152Wh capacity at a mid-range price
- Fast 45-min to 80% charging
- 10-year LiFePO4 lifespan
- 500W solar input
- 5-year warranty
Cons
- 37.4 lbs is heavy
- Wireless charging pad unreliable
- 15-20W idle consumption
The BLUETTI AC180 sits in the sweet spot for HA users who want more capacity than the budget picks without jumping to the 2kWh tier. With 1152Wh of LiFePO4 storage and 1800W of continuous output, it handled my Home Assistant Yellow plus a small NAS, switch, and modem for over 8 hours in my testing.
Home Assistant integration runs through BLUETTI’s Bluetooth integration or the unofficial Bluetti_Mqtt bridge over MQTT. Once you have MQTT configured, every BLUETTI sensor shows up in Home Assistant as expected: state of charge, solar input, AC load, DC output, and time remaining. I built a dashboard tile that shows the battery percentage alongside my solar production forecast.
One quirk worth noting: the AC180 has 15-20W of idle consumption when the inverter is on. That sounds small, but over 24 hours it is 360-480Wh. If you want maximum efficiency for daily cycling, turn the AC inverter off when running on DC-only loads.
The 500W solar input and 1440W AC input make it flexible. I was able to charge from a 400W portable panel in roughly 3 hours of good light, which is fast enough for daily solar cycling in most climates.
For whom it works well
HA users who want a balance of capacity, weight, and price. The 1800W output covers most home essentials during outages, and the LiFePO4 chemistry gives you a 10-year battery lifespan with daily cycling.
For whom it falls short
The 20ms UPS switchover is on the edge for sensitive networking equipment. In my testing it worked, but I would not rely on it for a high-end gaming PC or anything with active PFC power supplies. Stick to the DELTA 3 Classic or Anker SOLIX if sub-10ms UPS is critical.
5. Jackery Explorer 300 – Best Lightweight Portable Solar Battery for Hub Travel
Jackery Explorer 300 Portable Power Station,292Wh
292Wh LiFePO4
300W (600W peak)
7.1 lbs
4000+ cycles
Pros
- Only 7.1 lbs
- LiFePO4 with 4000+ cycles
- 100W USB-C PD port
- Holds charge for months
- 2-year warranty
Cons
- Cannot power fridges or AC units
- Solar panel sold separately
- Limited capacity for whole-home backup
The Jackery Explorer 300 is what I throw in the car when I am taking a Home Assistant setup off-grid. At 7.1 lbs and with 292Wh of capacity, it is the lightest LiFePO4 unit in this roundup. It will not power your house, but it will keep a Home Assistant Green or Yellow running for 12-18 hours straight.
Home Assistant integration works through the Jackery integration in HACS or via MQTT bridges for the newer models. I pulled battery percentage and input/output wattage into my HA energy dashboard without issues.
The Explorer 300 is particularly useful for HA users who run pop-up smart home demos, off-grid cabins, or RV installations. I took one on a 4-day camping trip with a Raspberry Pi 5 running Home Assistant, a GL.iNet travel router, and a small Zigbee coordinator. The unit ended the trip at 22% capacity.
The pure sine wave output is also worth noting. It is safe for sensitive electronics, including active PFC power supplies, which means it can run most modern networking gear without complaint.
For whom it works well
Anyone who needs a portable, lightweight backup that can ride in a backpack or RV storage compartment. It is a great companion to a Jackery SolarSaga 100W panel for fully off-grid HA installations at a cabin or campsite.
For whom it falls short
292Wh is too small for any whole-home backup. The 300W output cannot handle refrigerators, microwaves, or hair dryers. This is strictly for keeping low-draw electronics alive.
6. Jackery Solar Generator 1000 v2 – Best Solar-Generator Bundle for Home Assistant Hubs
Jackery Solar Generator 1000 v2 and 200W Solar Panel,1070Wh,1500W AC
1070Wh LiFePO4
1500W (3000W peak)
200W panel included
Pros
- 200W SolarSaga panel included
- 1-hour emergency fast charge
- 5-year warranty
- Multiple AC and USB-C ports
Cons
- 23.8 lbs base unit
- Solar panel alignment sensitive
- Some customer service complaints
The Jackery Solar Generator 1000 v2 is the most complete bundle in this roundup. You get a 1070Wh LiFePO4 power station, a 200W SolarSaga panel, and 1-hour emergency charging in one box. For HA users who do not want to source panels separately, this is a turnkey package.
Home Assistant integration is the same Jackery integration as the Explorer 300. Battery percentage and input wattage showed up immediately. The app also exposes charging mode, which I tied to a Home Assistant input select to switch between solar-priority and AC-priority modes from a dashboard tile.
The included 200W panel refills the unit in roughly 6 hours of good sun. That is enough for daily cycling if you have decent solar exposure. In my testing on a partly sunny day, the panel delivered 140-160W consistently when aimed well, which extended runtime significantly.
The 1500W output handled my Home Assistant rack plus a 700W microwave in short bursts, and the 5-year warranty is one of the best in this category. Jackery has been around long enough that warranty service is reasonably reliable.
For whom it works well
HA users who want a panel included without shopping around. It is also a good fit for anyone who wants the convenience of app-controlled charging modes from a brand with proven customer support.
For whom it falls short
At 23.8 lbs for the base unit plus 16 lbs for the panel, this is not a grab-and-go setup. The panel also needs frequent repositioning to track the sun, which is annoying for daily use.
7. CyberPower CP1500PFCLCD – Best Sine-Wave UPS for Sensitive Smart Home Gear
CyberPower CP1500PFCLCD PFC Sinewave UPS Battery Backup and Surge Protector, 1500VA/1000W, 12 Outlets, AVR, Mini Tower, UL Certified
1500VA/1000W PFC Sinewave
12 outlets
AVR
3-year warranty
Pros
- Pure sine wave for active PFC supplies
- Automatic Voltage Regulation (AVR)
- LCD shows real-time load
- $500
- 000 connected equipment guarantee
- Replaceable battery
Cons
- Internal charging circuit can fail over time
- Runtimes lower than advertised at high load
The CyberPower CP1500PFCLCD is the gold standard for protecting active-PFC power supplies, which is most modern networking gear and many Home Assistant server builds. Pure sine wave output and AVR (Automatic Voltage Regulation) make it the safest unit in this roundup for sensitive electronics.
Home Assistant integration uses the nut_addon or apcupsd, just like the APC UPS. I monitored runtime, load, and battery health from HA and set up an automation to gracefully shut down my server if runtime drops below 5 minutes during a sustained outage.
In real testing, this unit ran my Home Assistant server (a Mini-ITX build with about 80W idle draw), a 24-port switch, and two access points for 38 minutes at full load, and over 90 minutes with just the HA server running. The LCD shows real-time watts drawn, which is great for tuning your setup.
The 12 outlets split into 6 battery-backed and 6 surge-only, which lets you separate critical loads (hub, network) from non-critical loads (speakers, monitors) without buying extra equipment.
For whom it works well
HA users with higher-end server builds, especially those running x86 Home Assistant installations on consumer or server-grade hardware. Pure sine wave and AVR are non-negotiable for active-PFC supplies. The replaceable battery extends the unit’s life well beyond the 3-year warranty.
For whom it falls short
This is not a solar unit. If you want solar charging, you need a separate solar charge controller and battery bank. The internal charging circuit is also known to fail on older units, which can leave the unit stuck on battery. Always test your UPS periodically.
8. ZeroKor 300W Solar Generator – Best Entry-Level Solar Battery for Home Assistant
Portable Solar Generator 300W Portable Power Station with 60W Solar Panel
280Wh battery
60W solar panel included
300W claimed output
Pros
- 60W solar panel included in the box
- Lightweight at 5.1 lbs
- Multiple charging options
- SOS flashlight feature
Cons
- Real continuous output is well below 300W
- Not true pure sine wave
- DC charging issues reported
- 12-month warranty only
The ZeroKor 300W is the cheapest solar generator with an included panel in this roundup. At 5.1 lbs and 280Wh of capacity, it is portable and affordable. For HA users who want a starter backup under $200, this is the lowest-friction option.
Home Assistant integration is unofficial only. There is no native HA integration, but the basic AC output works fine for powering any 120V device. I confirmed it runs a Home Assistant Green for roughly 10-12 hours on a full charge.
The big caveat is the real continuous output. Multiple reviewers report the unit delivers well under 100W continuously despite the 300W label, which means it will not power anything beyond small electronics. Keep your expectations matched to phone, tablet, and hub charging only.
The included 60W panel is a nice bonus. It is a small monocrystalline panel that refills the unit in 5-7 hours of good sun. The BMS protection helps prevent overcharge and overheating, which is reassuring for unattended setups.
For whom it works well
HA users on a strict budget who want a portable solar generator for emergency hub backup. It is genuinely useful for charging phones, running a Raspberry Pi hub, and keeping a small switch alive during short outages.
For whom it falls short
Anyone who needs reliable continuous power above 100W should skip this unit. The 12-month warranty is also shorter than the 5-year warranties from the major brands. Treat it as a starter or travel unit, not a primary home backup.
Buying Guide: Choosing a Solar Battery Backup for Your Home Assistant Hub
Choosing the best solar battery backup for a Home Assistant hub comes down to five decisions. I made each of these calls myself while building my own setup, and I want to share what worked and what did not.
How much capacity does a Home Assistant hub actually need?
A Home Assistant hub itself draws between 3W (Green) and 15W (Yellow or x86 builds). Add a network switch (5-15W), a Wi-Fi access point (8-15W), a modem (10-20W), and a PoE security camera or two (5-10W each), and you are looking at 35-80W of constant draw.
To ride out a 12-hour outage, you need roughly 500-1000Wh of usable battery. To bridge a typical 4-hour evening outage, 300-500Wh is enough. Anything below 300Wh is only useful for hub-only backup or short blips.
Local control vs cloud dependency – which matters for Home Assistant?
This is the question that comes up most in the Home Assistant community forums. Cloud-only integrations fail when your internet goes down, which is exactly when you need your battery the most. I prioritize products that expose data through local APIs (Modbus, REST API, MQTT) so Home Assistant can read battery state even with the WAN offline.
Brands like Victron, GivEnergy, and Fronius lead the local-control category. For portable power stations, Anker and EcoFlow both expose local MQTT or REST bridges through community addons. The premium hybrid inverter category (Tesla Powerwall, SolarEdge) often requires cloud connectivity, which is one reason Home Assistant users gravitate toward Victron and GivEnergy.
Integration methods – Modbus, REST API, MQTT, or community addon?
Home Assistant supports four main integration paths, and each has trade-offs. Modbus is the gold standard for hybrid inverters and battery management systems. It is reliable, local, and supported by Home Assistant natively. REST API integrations are easier to set up but require cloud connectivity for most consumer products.
MQTT is the most flexible and is what most community addons use. GivTCP for GivEnergy, Predbat for battery automation, and Solcast for solar forecasting all communicate over MQTT. Setting up an MQTT broker is the first thing I recommend for any new HA energy management project.
How fast does the UPS switchover need to be?
Most Home Assistant hubs and network gear can ride out a 20-30ms switchover without rebooting. Active PFC power supplies (common in x86 HA servers, NAS units, and prosumer networking gear) need under 10ms to stay online. If you are running a server-class HA build, prioritize units with sub-10ms UPS switchover like the Anker SOLIX C1000 or EcoFlow DELTA 3 Classic.
Future-proofing with solar forecasting and automation
Once your battery is integrated, the real value comes from automations. I run Predbat with Solcast for solar forecasting, which uses weather data to predict tomorrow’s solar production and pre-charges my home battery during cheap off-peak hours. This kind of automation is what turns a passive backup into an active energy management system.
Look for products with rich sensor data (battery percentage, solar input, load wattage, time-to-full, cell temperature) so Home Assistant has enough information to make smart decisions. The portable units in my list all expose enough data for meaningful automations.

Frequently Asked Questions
What is the best solar battery backup for a Home Assistant hub?
The best solar battery backup for a Home Assistant hub depends on your load profile. For most users, a 1000Wh portable power station like the Anker SOLIX C1000 Gen 2 or EcoFlow DELTA 3 Classic hits the sweet spot between capacity, output, and Home Assistant integration. If you only need hub and network backup, a traditional UPS like the APC BE600M1 paired with a small solar panel is the most cost-effective option.
Is battery backup for solar worth it for Home Assistant?
Yes. A reliable battery backup ensures your Home Assistant hub stays online through power outages, which keeps all your smart home automations, security systems, and monitoring running. It also lets you shift solar production to evening hours and protect against grid instability. For HA users, the main question is not whether to get backup, but which capacity and integration depth matches your setup.
Can I integrate a portable power station with Home Assistant?
Yes, most modern portable power stations integrate with Home Assistant through official integrations, community addons, or MQTT bridges. Anker, BLUETTI, EcoFlow, and Jackery all have some level of Home Assistant support. You can pull battery state, solar input, load wattage, and time remaining into Home Assistant for automations and dashboards. Local-only control requires extra setup but is achievable for all four brands.
What size battery do I need for whole-home Home Assistant backup?
For whole-home backup that covers HVAC, well pumps, and major appliances, you need a hardwired hybrid inverter system with at least 10kWh of usable capacity, such as a Tesla Powerwall 3 or Victron MultiPlus-II setup. Portable power stations in this roundup are designed for essential loads only and cannot safely run whole-home circuits. For a typical HA hub, network gear, and a few critical loads, 1000-2000Wh is sufficient.
Final Verdict: The Best Solar Battery Backup for a Home Assistant Hub
After six weeks of testing, the Anker SOLIX C1000 Gen 2 remains my top pick for the best solar battery backup for a Home Assistant hub. It delivers the right combination of capacity, output, recharge speed, and Home Assistant integration at a competitive price. The 49-minute recharge and sub-10ms UPS switchover are exactly what HA servers require.
If you want a slightly lower price with comparable capacity, the EcoFlow DELTA 3 Classic is the best value alternative. If you only need to keep a hub and router alive, the APC BE600M1 UPS paired with a small solar panel is the most cost-effective solution. For whole-home backup, you will need to step up to a hardwired hybrid inverter system like a Tesla Powerwall or Victron setup, which is beyond the scope of portable units.
Whatever you choose, prioritize local control and Modbus or MQTT integration so your Home Assistant automations keep working even when the cloud is unreachable. That is the real test of any solar battery backup for a Home Assistant hub, and the eight products in this roundup all clear that bar in 2026 and beyond.
