Hi good, I have the following set up, 1 x Mppt 150/100, BMV702 with CCGX, Multiplus 24v/5kVA, with 12 x OPZV600 2v cells, 9 X 250Watt PV's. system has been working ok until recently moved now on reset, have noticed the MPPT is charging the Batteries at 29.4V, whereas recommend edand all presets are at 28.8V, thie system is mains connected ( No FIT). and set up on standard ESS,
I have set to both GEL/AGM and also tried the OPZS/OPZV option with no change,
I have checked the MPPT settings and have set the Rotary to 0. (GEL), and then tried user defined as per Battery manufacturer instructions,
The system indicates that the control is EXT. Control, ( I guess the ESS?
A little concerned that higher voltage chargng can cause a longer term issue with the batteries, and information welcome, thanks,
