A refrigerator, Wi-Fi router and several LED lights form a common essential-load package. The right battery is determined by startup power plus daily energy, not by adding device labels and guessing.
Start with the refrigerator
The compressor usually creates the largest startup event. Wi-Fi and LED lighting add relatively steady loads. Measure refrigerator energy use when possible because cycling changes daily consumption.
Use our guides to measure refrigerator energy and understand starting vs running watts.
Build your exact outage plan
Add refrigerator, Wi-Fi and the number of lights you need, choose outage duration and solar access, then let the Backup Power Map calculate the minimum.
For a step-by-step battery sizing path for this exact load mix, see Battery Backup for Refrigerator, Internet & Lights During an Outage.
1kWh or 2kWh?
A 1kWh-class system can be appropriate for shorter, lighter plans if the refrigerator startup fits. A 2kWh-class system provides more stored energy for longer outages and can offer higher inverter headroom. The calculator should decide the class before you decide the brand.
