Considering adding another battery - inverter options
Hi all, At the moment I've got 4.8 kW of solar, a Growatt SPH5000 hybrid inverter and 15 kWh Seplos battery.

Solar panel and battery quandry
Good Afternoon. Today I was to have my Octopus Solar panels and Battery
installed. Unfortunately,
when the roofer (and all the materials turned up), he declared that the repair
to the felt under the roof tiles, was not satisfactory. He also said that

Does anyone have advice how to do this with minimum impact financially? I…
