Frequently Asked Questions
What can this kit run?
The battery stores 20.48kWh, around 18.43kWh usable after inverter losses, and the array puts back about 0.2kWh on a clear day. That covers lighting, a fridge, Wi-Fi, device charging and larger loads like a microwave or power tools. See the What It Powers tab.
Do I need anything else?
No — the panels, battery, inverter, controller, cables, fuses and brackets are all in the box. You will need basic tools and fixings suited to your roof or mounting surface.
Can I expand it later?
Yes. You can add panels within the charge controller's input limit and add batteries in parallel for longer runtime. Keep added panels the same model where possible — mismatched panels in one string pull the whole string down to the weakest one.
