EVEC home charging unit
Has anyone got / had experience of the EVEC home charger? My PodPoint has finally given up after 8 years (solid red light) and I'm thinking of replacing it. I don't require a smart charger - and after reading some of the reports of their foibles on various forums - I don't really want one. TIA Dave F

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.
