2100 ah bank not enough solar array
This system was built with the intention of adding more solar panels in the near future. Well things have changed and the solar array is too small to efficiently charge the 2100 ah battery bank. That is 5 strings of 4 420 ah batterys for a total of 2100 ah at 24 volts. The solar array is able to produce 1890 watts flowing through a T80HV Apollo solar charger which I think might be able to take 3 more similar solar panels to help out. As it is the array can just barely generate enough power to do an equalize charge on the sunniest of days. I am concerned that I am going to lose the battterys due to not being able to charge them adequately. There is a back up generator that has to take up alot of the slack. What does everyone think of dividing the bank up into two appropriately wired up banks and charge one and use it for a week or two and then switch to the other half. The idea being that the exsisting array could more efficiently charge a smaller battery bank.
