Had to get a home PV system out of necessity due to our national power company being up a shitcreek with an aging fleet of badly maintained coal power plants.

3.7 Kw solar panels and 2 x 5KW LifePO batteries and a 5Kw SunSynk inverter tied to the grid - solar geyser and it does not power our electric oven - the only issue is the management system is dumb as bricks - there is no intelligence and difference charge settings or profiles for our cold winters and hot summers or using the weather forecast for the day.

It just averages out.
