Hello,
I am having my setup completed today for a new-built house. I asked the electrician if I double the battery, and he's saying the battery may charge itself with the grid, so it's best to monitor the usage.
We use the dryer and washing machine a lot in the house, and we have just installed underfloor electric heating. We also have a big server drawing a lot of power, which we had to power down for a year due to electricity costs.
As the battery is modular, we are thinking of doubling up, but it does not make sense to charge the battery from the grid.
Any tips and opinions would be much appreciated.
