I have a 15kVA / 48V Quattro inverter. A bank with 8 200AH batteries, 4 in series, 2 in parallel. In other words, the bank is 48V / 400Ah. I also have a generator that will automatically start when the voltage across the batteries is very low. The supplier of the equipment in my country, Chile, told me that I must configure the inverter to charge with a maximum of 10A, because I have 12 solar panels to charge the system and a SmartSolar 250/100 charge regulator. He tells me that if the generator works and at the same time the charge regulator injects the batteries, the currents will add up and could damage the batteries. I did it like that. The client called me one day saying that he has been running the generator for almost 10 hours (at night) and he cannot raise the voltage of the batteries ... I remembered the configured 10 A load ... My question is: is the above correct? by the local dealer? What options do I have to take advantage of the power of my generator and charge my batteries as quickly as possible, regardless of whether the charge controller is injecting or not? Thank you
