Re: How do you store excess energy?
Well I guess I am in the problem area. I have 400 watts of tiltable solar with 674 amp hours of battery capacity. At times like this, it is sunny in Grenada just now, I will be fully charged by mid day and the charge controller will be in dump mode.
There have been times I would run my Spectra watermaker on days like this but the running costs exceed the cost of buying water so all those lovely amps are going to waste.
Not much point in heating water as a solar shower gets too hot too use in a couple of hours.
Well I know of one popular solution, turn the fridge up and get the beer REALLY cold.
