Buying Guide
What size capacity do you need?
Evaluate essential appliances and typical outage duration. For longer outages, aim for 5000–7000Wh with scalable options. If you only need to power a few devices, a 3000–4000Wh unit may suffice.
Do you need 120V or 240V service?
240V capability powers more appliances in homes with larger loads. If your devices run on 120V only, a 120V system may be enough and often lighter and more affordable.
How important is rapid recharging?
Fast AC and solar charging reduces downtime between outages and sun cycles. Look for higher input wattage and a LiFePO4 battery with a long lifespan for better performance.
Expandable vs. fixed systems
Expandable systems offer long-term growth as energy needs change, though they may require more planning. Fixed systems are simpler but less adaptable to future upgrades.
Safety and battery chemistry
LiFePO4 chemistry is common for home backup due to stability and a long life. Ensure the system has a robust BMS with overcharge, over-discharge, short-circuit, and thermal protections.
How to connect to your home
Some systems offer direct transfer switch or inlet box integration for faster installation. If you lack electrical experience, prefer models promoting simple plug-and-play setup with guidance.
