Im not explaining how to do it. Im asking what would be my best option.
solar array is 3660w max (no wind or hydro). My array is not oversized. The battery is 60v 16s Li-ion. I am using a grid tie inverter with limiter (GTIL2) that uses battery (if pv power itself isnt enough) when needed throughout the day. Outback fm60 chargecontroller.
Im wanting the excess power the array can produce to be sent to hotwater heater when battery is full-in float. Or for the hotwater heater to be turned on so GTIL2 can power the hotwater heater when excess is available and battery is full. The outback has a few aux options that might help to achieve this. Ill put pics below of those options. Im ok with changing one of the hotwater heater elements to dc, but would prefer to keep the elements AC so I can heat the entire tank of water if excess pv isnt available for some reason.
Standard diversion controllers seem to use voltage only (not amps). I understand that they can be set to activate when float voltage is achieved. How do they make sure when theres any excess pv power (that the LOADS ARE NOT USING) that the power goes to the hotwater heater. Also when theres not excess because the loads need the available pv power how does the diversion controller allow the loads to use that power instead of the hotwater heater using that power?
