We have a grid tied 10kw pv system... to date we have used just whatever produced power was available at the time without any storage or harvesting.
Due to the horrific jumps in energy cost we would love to harvest the energy to batteries, also we thought to take the low night rate available to boost the batteries while we sleep.
Is there an AC connected device that we could use without going to the large expense of a Powerwall or similar... I was struggling to find a device on here?
Also just to add to this.... I have a stack of little used motive batteries (lead/acid) left from a job, I know these don't compare to Li-ion but I have them so essentially they are free gratis... will any of the inverter charges be able to link to them?
Many thanks, Craig
