Solis 4G series

Hi @Wrightsolar

Welcome and thanks for your post. It doesn’t strike me as particularly good value, no. Also not the best products going around.

You can get a rough idea for price here:
Solar Calculator | Panel and battery cost, savings, payback and ROI

Also see our articles on best inverters and panels:

It’s probably worth getting a few more quotes.

Cheers
Marty
