Coulomb Posted July 9, 2019 Share Posted July 9, 2019 It looks like you can leave your main charge parameters to their defaults: setting 26 (Bulk/CV/absorb voltage) 57.6 V, and setting 27 (float voltage) 54.0 V. Perhaps by "cycle" they mean a gentle equalise, to be performed every couple of months or so. That would be at 58.8 V, though your inverter probably won't let you set to higher than 58.4 V. They suggest C/4 maximum charge current, so that would be 100 A for your two strings of 200 Ah each. That seems a little high for these, but your panels will rarely charge at more than 60 A (0.15C, the usual figure). That's setting 02, maximum charging current. Settings 12 and 13 (back to utility and back to battery) voltages always seem to need adjustment for personal preferences. I'd raise setting 12 to 48 or possibly 49 V, and setting 13 could stay at the default of 54 V. Quote Link to comment Share on other sites More sharing options...
