Re: How do you store excess energy?

I made a simple circuit that flips a relay on the thermostat wire whenever the voltage gets to 13.5V during the day. The freezer/fridge compressor stays on (at the higher speed) until nightfall.

It's only about 4 or 5 amps, and we have 590 watts of solar strapped to our bimini.

Next step is to put it into the hot water heater, but I want to understand more about how the hot water heater's circuit works and how many watts the element is. (We have an extra, WalMart type inverter but may wait until I gat a marine inverter.)

There was one cruiser who put the extra energy into a watermaker. He had the extra fresh water going into a bucket in the cockpit for doing laundry. (Forget who it was, but google "Bene505 watermaker bucket cockpit site:cruisersforum.com" and "Bene505 watermaker bucket cockpit site:sailnet.com" and you may find the thread.)

Regards,
Brad
