Apart from Tesla (Powerwall) and now SolarEdge, who else produces home battery storage solutions?

Solaredge don't make the batteries - they are just a repackaged. I would suggest you look at the actual battery producers in China who make the LiFePO4 cells that most of these battery packs contain

@batalto, I'll check them out. I think I saw a while back that there was a manufacturer (they may have been British) that were producing salt water batteries.

@editor there are a few. I'd suggest looking at the cell makers, for example EVE. The "manufacturers" mostly take the cells, add a case and a Battery Management System (BMS). Some, like Pylontech actually make the cells too.

I have 16.6kW/h BYD HVM battery with a Fronius Gen 24 inverter. Very happy with them so far, currently 16 months old.

Happy to answer any questions about them. I think quite a few inverter manufacturers are now using these batteries as an approved storage solution.

In Spain my electricity is now about 38p kW/h from 6pm to 10pm. 95% of the time in winter the batteries last at least until 10pm, often until after midnight where electricity is currently a bargain 25p kW/h so saves significant amount.

Currently in Spain you are not allowed to charge the battery from the grid at night on the cheaper rate, hopefully that rule will change one day.
