We've been running the following 24V set-up for just over a year:

4 x 250w 24v pv panels, each pair connected first in series then the pairs connected in parallel
Victron mppt 100/50 controller
Victron BMV700 monitor
Victron inverter
4 x 6v Crown CR220 FLAs

The system has operated flawlessly and our useage is very low. Consequently we never dip below 95% charge during summer (compared to down to around 65% in winter). Most recent SG readings had three batteries at 1.31 and one at 1.3 at 17degC.

With advice from the forum (and especially Scruff - thank you) I did some manual EQ charges at the start to bring the batteries up to consistent charge but haven't done so since Feb because the batteries have been largely consistent across all cells and our cycles are very shallow.

Should I still carry out an occasional EQ charge for battery health or is it unnecessary?
