Hello,
I'm just now setting up my off-grid system. I've connected my Growatt SPF 3000TL LVM-ES to my solar array and my battery bank. The battery bank is reading 52 volts, so it should be charging, but it's not. If I put a load on the output the battery powers the output, but the PV does not. But I have Solar Priority set for Prm01
Battery = 2X AmpereTime 24V 100AH in series
PV = 4 x 250W 37.6V nominal, Actual Volage ~33 volts each, input array voltage reading ~140V (shown on Growatt)
Prm01 = SOL
Prm19 = Prm20 = 58.4V
AC input is currently disconnected.
Any ideas why my array will not power the load, or charge the battery?
Thanks for any help offered.
Ron
