Our picks at a glance
Best overall: EcoFlow DELTA Pro 3About 4 kWh, 120/240V, a fast UPS switchover and a mature smart home panel ecosystem. Check price
Most power: Anker SOLIX F3800 PlusA 6,000 W split-phase inverter for well pumps, central HVAC and EV charging. Check price
Most modular: BLUETTI Apex 300Starts at about 2.8 kWh and scales to very large battery banks. Check price
Best value: Jackery Explorer 2000 v2About 2 kWh for fridge-and-essentials backup without whole-home pricing. Check price
When the grid goes down for more than a few hours, a 1 kWh portable unit runs out fast. Home backup power stations store 2 to 4 kWh in a single box, accept expansion batteries, and can connect to your electrical panel through a transfer switch so they power real household circuits instead of extension cords.

EcoFlow DELTA Pro 3: best overall
EcoFlow DELTA Pro 3
The DELTA Pro 3 is the most balanced whole-home unit on the market: about 4 kWh in one wheeled box, both 120V and 240V output, and a fast UPS switchover so your router and fridge do not even notice the outage. Paired with EcoFlow's Smart Home Panel, it powers selected circuits automatically. Extra batteries extend runtime for multi-day outages.
- Large capacity with 240V
- Fast UPS switchover
- Mature smart panel ecosystem
- Very heavy
- Premium price, especially with the panel

Check the DELTA Pro 3 priceAnker SOLIX F3800 Plus: most power
Anker SOLIX F3800 Plus
The F3800 Plus has the strongest inverter in this group, delivering true split-phase 120/240V at up to 6,000 W. That makes it the pick if you need to start a well pump, run central HVAC or charge an EV during an outage. Its high solar ceiling also makes it a strong base for an off-grid setup.
- 6,000 W split-phase output
- High solar input
- Expandable to large capacities
- Heavier than the DELTA Pro 3
- Slightly smaller base capacity
BLUETTI Apex 300: most modular
BLUETTI Apex 300
The Apex 300 is designed as a building block: start with one unit and add batteries or a second unit as your needs grow. It offers 240V and a 0 ms UPS mode, and works with BLUETTI's home integration hardware. A good choice if you plan to build up a large system over several years.
- Highly modular
- 240V and seamless UPS
- Lighter than the 4 kWh units
- Smaller capacity per unit
- Full system gets expensive
Jackery Explorer 2000 v2: best value
Jackery Explorer 2000 v2
If you mostly want to protect the fridge, internet, lights and a few devices during outages of a day or less, you do not need a 4 kWh flagship. The Explorer 2000 v2 offers about 2 kWh at around 40 lb, a fraction of the weight and cost of the whole-home units. It does not support 240V appliances.
- Much lighter than 4 kWh units
- Good capacity for the price
- Simple to use
- No 240V
- Not for whole-home backup
How to choose a home backup power station
1. List your essential loads
Fridge, freezer, sump pump, well pump, furnace blower, internet, lights and medical devices. Our sizing guide shows how to turn that list into a capacity target.
2. Check for 240V needs
Well pumps, central AC and Level 2 EV chargers usually need 240V. If you have one of these, skip the 120V-only units.
3. Plan the connection
Budget for a transfer switch or smart home panel and a licensed electrician. This is what turns a big battery into real home backup.

4. Think about recharge
For outages longer than a day, solar panels or a small generator to recharge the battery matter as much as capacity.
Method: picks based on manufacturer spec sheets, independent tests published by specialist media and owner reviews. We have not lab-tested these units ourselves. Home electrical work should be done by a licensed electrician.
