Community Insight from Reddit
- A real-world setup:
“I have a Givenergy battery. After speaking to my installer they added a manual isolator… limited to max 3.6 kW, but I can run essentials… lights, boiler, TV, fridge… when the battery is drained, that’s it.” Reddit
- Another user advises:
“Hybrid inverters… allow you to use the solar panels during an outage, even without a battery. Retrofitting hybrid inverters can be easy or very expensive.” Reddit
