Hi,
My recently installed system (not really yet in use) has been floating the batteries for the past couple of very sunny days - about 8 to 10 hours per day. The Conext SCP tells me (as you can see in the attached picture) the float voltage is 54.4 volts (factory default) at 0.7A. The PV in is coming from 12 x 280W panels, all in series, using a MPPT 80-600 charge controller.
I have 8 Rolls S-550 (428Ah) batteries, all in series.
My Conext Battery Monitor still tells me that the batteries are 97% full.
So I have two questions:
1. is it normal that the current is so low? I would expect more a 4-5 amps than 0.7-0.8A.
2. should I change the float voltage and slightly increase it?
Thanks,
