Ac Coupled Dump Load
 

So after playing with settings with the solar edge and critical loads panel the Schneider sw 4048 does frequency shift and the solar edge drops the output. This is fine and works . But right now i have a smallish battery bank of 48 volt 133 ah. I am trying to figure out what would be the easiest way to make the system so it keeps using the power as it comes in from solar to a water heater . As the water heater uses the most of my energy consumption here. Has anyone done a Ac coupled dump load per say ? Obviously past experience is better than my calculation on paper thoughts.

Add a SSR to switch the water heater, then use an Arduino to control it based on the water temperature and battery voltage.

Thanks . I will add that to heat the pool up as secondary first will preheat the water going to the water heater
