Electricity needs when the grids down.

[Pete Grey]

I think 300+ watts should give us some useful power, winter daylight does give some but obviously not as much as bright summer sun, the solar is for battery charging not to run any appliance.

While there is mains power we can use that for battery charging.

12v lighting is safe and convenient. How many fires will candles and oil lamps cause ?.

If there is no more mains that’s another ballgame.
