I have a Multiples inverter/charger. I use it to charge my three parallel strings of 24 volt Trojan batteries. When setting up the inverter's DC cut-off voltage, pre-alarm voltage, etc., I used the the SOC voltages given by the battery manufacturer. Obviously these voltages are open circuit voltages. My question is, is the inverter capable of compensating for the difference in open-circuit voltage and the voltage under load/charge when deciding, for instance, that the battery's SOC is where it should sound the pre-alarm or cut-off power?
What is the best way to go about protecting my batteries against low discharge. I would like to consider all options and know about their pros and cons. The batteries are also being charged from a small array of solar panel using the Victron MPPT charge controller. Obviously right now the inverter/charger doesn't know that the batteries are being charged from solar as well, and if possible, I would like to interconnect the two so that somehow I can maximize my utilization of solar power by giving priority to the the solar charger.
Thank you in advance.
