My situation is this. I have a large PV array 2600 watts running into two 100|50 MPPT charge controllers, I have 2x 3000|24 Multiplus inverters, BMV702 and a raspberry pie connecting it all together running Venus OS. I also have a 260 amp 24v DC alternator onboard that will charge the battery bank and help power loads.
My question is, how can I force the PV / MMPT chargers to always output if there is a draw on the system. I have set my alternator to charge to 27.8v while my MPPT chargers charge to 28.4 (temp compensated) . Often times I'll run two air conditioners, using close to 3000 watts. If my battery bank is not full and the MPPT chargers are still in bulk mode, it will work pretty well with the chargers continuing to contribute to the loads and the battery bank will fill. However once the bank is near full the MPPTs throttle down and the alternator takes more of the AC load, which puts my strain on my diesel engine costing me fuel and power.
With the tools at my disposal here, how can I have the MPPT chargers contribute even if the battery bank is full. I thought a few years ago the DVCC used to work this way and it would trigger the chargers to assist.
Thanks for any help you can provide.
