Re: Help with Charge Controller Choice
Well let's see 16 * 230 = 3680 Watts total. Under most circumstances that would probably run 2834 Watts average. Divide by charging Voltage of around 58 Volts (get an accurate number here) and you get 48.8 Amps of current. In other words it isn't likely you'd need more than a 60 Amp charge controller here. That gives you lots of options including Morningstar, Outback, Xantrex, and Midnight Solar.
Be careful configuring such an array. You really need to know the panels' Voc and Vmp to get it right. 29.5 Looks to be the Vmp, and two in series would then be 59 Volts. That is barely charge Voltage for a 48 Volt system, and once the inevitable system losses are factored in it would not be enough. Certainly not for equalization. So it looks like you need a minimum of three in series. Then you have to watch the Voc which is likely 7 or 8 Volts higher. That means the Voc on a string of three could be 114 Volts. Note that 16 doesn't divide by 3, and if you go four in series the Voc could then be 152 which is over the limit for all the controllers except the Midnight.
But you need specific data for your panels to be sure.

Ohm's Law: Amps = Volts / Ohms
Power Formula: Watts = Volts * Amps
