Top Home Power Storage Batteries Compared for 2025
1. EcoFlow RIVER 3 Plus
If you’re looking for a compact home power storage solution with solid performance, the EcoFlow RIVER 3 Plus balances quality and affordability. Thanks to X-GaNPower technology, it can deliver twice the runtime for small appliances under 100W.
Despite its small footprint, the EcoFlow RIVER 3 Plus pushes up to 600W of continuous output, and with X-Boost mode, it can handle surges up to 1200W. That covers about 90% of household devices, from kitchen gadgets to heaters. The built-in LED light and <10 millisecond switchover UPS function are perfect for blackouts, keeping your fridge, router, or computer running without a hiccup.
2. EcoFlow RIVER 3 Max
EcoFlow RIVER 3 Max is a powered-up version of the EcoFlow RIVER 3 Plus. This home power storage battery includes a Smart Extra Battery (EB300), nearly doubling the system’s capacity to 573 watt-hours (Wh). That extra juice makes a big difference: it can keep a 60W car fridge running for about seven hours, power a game console for four hours, or keep a mid-size refrigerator humming along for an hour.
The trade-off is portability. The EcoFlow RIVER 3 Max is heavier than the EcoFlow RIVER 3 Plus, but it still isn’t unwieldy. It’s more of an investment, but you’re paying for peace of mind. If you’ve ever worried about your home battery backup system dying too soon during an outage, the EcoFlow RIVER 3 Max is a good choice.
3. EcoFlow DELTA 3 Max Plus
The EcoFlow DELTA 3 Max Plus costs more than the smaller EcoFlow RIVER series, but this battery can comfortably support 99% of household appliances. Add X-Boost mode, and you can even power higher-wattage devices like ovens or hair dryers. Suppose your priority is reliable whole-home battery backup with the option to take it on the road. In that case, the EcoFlow DELTA 3 Max Plus is the best home power storage battery for your situation.
With a hefty 3000W AC output (and a surge capacity up to 6000W), it’s built to handle refrigerators, microwaves, and power tools.
EcoFlow DELTA 3 Max Plus is expandable up to 10kWh of LiFePO4 battery storage, so you can scale up for multi-day outages or heavy usage.
The EcoFlow DELTA 3 Max Plus isn’t limited to recharging via a wall outlet. It has five recharge methods, including solar panels, car charging, an 800W alternator, and the Smart Generator 3000, which essentially gives you infinite backup time.
If speed is a concern, the EcoFlow DELTA 3 Max Plus charges from zero to 80% on AC input in 43 minutes.
4. EcoFlow DELTA Pro Ultra
EcoFlow DELTA Pro Ultra is a premium home power storage battery priced at $8,598 CAD. This is not just an "in case of emergency" battery: it keeps your entire household running for weeks. With a base capacity of 6kWh that scales all the way to a staggering 90kWh, it can deliver a month of energy when fully expanded.
Unlike smaller power stations, the EcoFlow DELTA Pro Ultra is UL1973 and UL9540 certified, making it one of the few home battery storage systems to meet such rigorous safety standards. It includes casters for easy movement and is stackable for compact storage in your home. In cold climates, the self-heating battery ensures reliable performance even when temperatures drop below freezing.
5. EcoFlow DELTA Pro Ultra + Smart Home Panel 2
Bundling the EcoFlow DELTA Pro Ultra with the Smart Home Panel 2 turns a high-capacity battery into a complete home energy solution. The DELTA Pro Ultra already delivers scalable storage—starting at 6kWh and expandable up to 90kWh—but the Smart Home Panel 2 is what makes it practical for everyday backup. By wiring directly into your home’s circuits, it provides automatic switchover during outages, so essentials like lights, refrigerators, and medical devices stay powered without interruption.
The Smart Home Panel 2 also enables intelligent load management, letting you prioritize which circuits to keep running and helping you stretch available energy for longer blackouts. For families who want their backup power to feel invisible and automatic, this combination is the most convenient way to keep the entire home running smoothly.
6. EcoFlow DELTA 3 Solar Generator (PV220W)
The EcoFlow DELTA 3 Solar Generator is one of the most versatile home power storage batteries on the market. It’s perfect for home backup, RV life, or camping trips where reliable power is a must.
Unlike standalone batteries, this all-in-one system comes paired with a 220W solar panel, allowing you to both capture energy from the sun and store it for later use. With X-Boost technology, it delivers up to 2200W of output, enough to run 99% of household appliances, from refrigerators and TVs to hair dryers and microwaves. The system is also built to last 10 years with daily use, or more than 3000 cycles. The battery also has a five-year warranty, and the solar panel has a 12-month warranty.
The dual-sided solar panel is also a game-changer. It can capture sunlight on both sides, boosting output to 24% more power than standard single-sided panels. The adjustable stand makes it easy to position for maximum absorption, and the IP68 waterproof rating keeps it going in even the toughest conditions.
7. EcoFlow DELTA Pro 3 Solar Generator (PV400W)
At $5,898 CAD, the EcoFlow DELTA Pro 3 Solar Generator is an investment, but it offers tremendous peace of mind. It’s best for whole-home backup or extended off-grid living. With a solar input of up to 2600W and dual PV ports (high and low voltage), it captures and stores massive amounts of solar energy. Thanks to its 99% MPPT efficiency, you’re getting nearly all the usable power out of every ray of sunlight.
With its huge AC output, the EcoFlow DELTA Pro 3 can handle virtually any household appliance. Despite its size, it’s still easy to move around, thanks to its built-in handle and wheels. Combined with its high solar conversion efficiency, the EcoFlow DELTA Pro 3 recharges quickly, meaning you’ll spend less time waiting and more time enjoying your devices.
