I am just doing research on building my power system for a van. Now from what I understand the charge controller regulates but also hinders power going to the battery bank. My question is a 5000w 40amp gas generator would put out more power than a 12v battery bank would receive from one of the 80amp mppt controllers correct? And if this is correct is there any way to get around the flow problem to charge the batteries fast and maximize the generators output safely?
if something is producing a current of 40 amps with an energy rate of 5000watts it is creating a voltage of 125 volts. if something is producing a voltage of 12 v and 80 amps of current are flowing then 960 watts of power are involved. You have used the term 12v battery bank. This implies that there is a set of 12v batteries. Each battery is capable of being recharged independently if only the correct circuitry is provided. Each battery in such a system would be the limiting factor in the time taken to recharge the battery. If too much current is driven through a battery heat can accumulate and destroy the battery. There is insufficient information here to determine what can be done safely. The details of how the 12v batteries are built determines how rapidly they can be recharged.
