So I've set up my system and it runs pretty good, most days it's in use, batteries are full or on trickle by 10am to 11am.
I also have a 6 gallon electric water heater I currently run off a Genny. I'm thinking I'd like to use the over flow from the solar pannels once the batteries are full to run the electric water heater... If it's possible?
Here's my set up

CC is a EPever 30A, inverter is a 1,500 with 3,000 peak load and it has a 110v plug on top that my fridge is plugged into, inverter is currently set to sleep after load is gone and kick on when it senses load.
Water heater pulls about 13.75A (tested with kill-a-watt) and takes about 30 min to reach tempature. Based on this if I ran the water heater off the inverter it'd pull 1,650W (120vx13.74A). I can't remember all the math I had to do to set this up, but I'm thinking 1,650W /12v DC is 137.5A DC pulling from the batteries (+20% inverter conversion) is 165A DC for 30 min is 82.5Ah out of 214 total Ah on tbe battery bank would be 39.7% pull leaving me with 60.3% Ah left in a 30 min time frame.
I see a couple things wrong with this:
1) that's to deep of a draw down to be healthy for the batteries
2) The discharge rate is way to extreme and will cook the plates/batteries.
Since running the water heater off the battery bank does not seem to work ( unless I'm missing something), ...is there a way to run the water heater off the PV over flow once the batteries hit float charge and can this be done on some type of automatic switch so I don't have to be present to make it happen?
Thanks
