Hello,
I've tried to equalize my batteries again and it looks like I failed once again. I have 8 rolls S-550 (428Ah) wired in series. This morning, I started the generator until current started to taper down. Them, I let solar do its job for a few hours (about 5 hours) until I reached float. When I reached float, I tried to start the equalization process.
There was (and still is) plenty of sun right now and I'm starting the equalization process from the two Conext MPPT 80-600 CCs to equalize using the PV.
When I switched to equalization, the batteries started to climb to 59.5, 60.5 and 61V for a few minutes (about 10-15 minutes) then voltage dropped rapidly to 56V, slowing going down. One of the two CC switched back from equalize to bulk and the other one kept on equalization. But voltage was still at 56V. Few minutes later, both were out of the equalization stage, back into absorb for a few minutes and then, back to float.
Why is that? Help me understand as I have tried two times with them results.
Thanks,
