I was wondering who knows the answers to these questions?
I am putting together an array of 6 marine deep cycle batteries to make a 72 volts battery bank.
I ordered 2 PMA's (permanent magnet alternators that charges up to 300amps) to recharge the batteries (each PMA to charge 3 batteries)
There is one 72volt/300amp motor controller running two 15/20hp Permanent Magnet electric motors as the primary drive and the two PMA's will be driven off these to recharge the battery bank.
I want to recharge the batteries individually using 2-12v regulators to regulate the PMA's down to 12volts(voltage usually increases with the rpm's). 12 blocking diodes to go each battery (6-negative terminals, 6-positive terminals) to allow each battery to recharge without any drawback form the battery bank.
As the consumption of the drive motors increases with the rpm's so will the output of amps from the alternators thus trying to get as close to a 1-1 drain to charge ratio as possible.
So here are the problematic questions:
#1 What size voltage regulators do I use to handle these 300 amp PMA's
#2 Where do I get them?
#3 What size blocking diodes are suggested as well?
