Hi
I see a few threads about what people do with excess energy from solar and most seem to heat stuff up
In my case I have a house with 4Kw solar array and with grid tie in and FITs contract, meaning my system can not change with out screwing up the FTIs so fitting a new inverter with a powerbank charging and discharging feature is not possible.
I have a solar diverter for my hot water but still I have excess energy, i could just turn up the temp on the heater and make the water hotter, but ppl would hurt themselves with hot water taps so that's not practical.
I would like to store the excess energy in battery bank using it from the AC plug.
I would need to know when im exporting and how much and to use that to regulate a charge that's connected to a AC battery charger, also a battery charger that could be controlled like this.
The battery bank will be a Li-ion chem. between 10-20kwH
Does anyone know of such a device on the market or a selection of devices that can be cobbled together to work this way?
Also then using this power I could convert back to AC and power the same water heater so that when ppl use the shower at night I don't rely on Gas to reheat it for a morning shower?
I'm sure i will find other applications for the power but starting small and a good use case etc.
