Connecting a 48 volt Zephyr fan directly to battery bank?
I had an automatic transfer switch installed with my SMA Sunny Island/ Sunny Boy system. I was using the "BatVtgOut" off the circuit board to power the Zephyr Battery Box Ventilator at 48 Volts DC. I now need to power the fan off the battery bank directly. The battery bank is 200 Ah at 48 volts. Can I directly hook up the fab to the battery bank? I am not sure because the battery bank is rated at 200 Ah. Or do I need to put something in between the fan and the bank to handle the 200 Ah's?
