48VDC loads on 3.6kW inverter with CATL battery
Hi everyone, I am looking at installing a 48VDC immersion heater to make use of excess power while the sun is shining. If the MPPT is capable of charging the battery while supplying the inverter is there any reason I can't do this? We're thinking of installing 6.9kWp of PV and a 10.24kWh CATL battery bank. If we're using 3.68kW on the AC (which we want to be doing as much as possible) and the PV is at peak can I match a DC load to the max charge current of the MPPT? Discharging the battery and keeping the as much load on on the PV. The reason for this is due to the maximum generation capacity on site being 3.68kW. We want to use as much solar power as possible, but can't use it on the AC side for the above reason.
All the best,
Ben.

You would need 48VDC controller that can modulate the power based on available excess solar, i'm not aware of anyone actually making those. 230V ones are a lot easier to find.
