FAQ
How many watts do I need for whole-home backup?
Most homes can ride essentials (fridge + lights + Wi-Fi + medical) for 8 hours on a 2 to 4 kWh system. Whole-house is a different question best answered with the Runtime Calculator.
Should I get a transfer switch?
For multi-kWh installs, yes. A transfer switch is the difference between 'I can charge my phone' and 'I can run my fridge the whole outage'.
