Hi,
I would appreciate your help confirming that everything is OK with my charging system please.
I have just replaced some old flooded batteries with a LiFePo4 320Ah pack. All balanced, connected and set as recommended on this forum (an YT). The Daly BMS 100 settings are below (14.40/12.00 V cut off). I have customized the Morningstar MPPT45 controller as recommended with max absorption 14.40V (no temperature compensation and equalization). Once the battery is back to 100% SOC the DALY BMS cuts off charging, the bluetooth BMS Smart app shows nicely 0 Ah and solid 13.8V (going down quickly from max 14.4V).
However, the solar controller MSView software shows fluctuating voltage (up to 21V) but no current. I can see similar fluctuations 10 meters from the charging system/battery at my 12V sockets...
1. Is it safe for my batteries and equipment to ignore it or should install some kind of additional regulator (shunt 14.4V) as a barrier for these voltage
I can physically switch off the connection panels/controller and obviously it stops that issue but it can't be monitored all the time.
2. Another question - the Battle Born Batteries in setting up the MPPT controller at:
changed the Absorption voltage to 14.40V but left the absorption time as 2.5h. Is it correct?
Please let me know what could be done about it.
All the best,
Conrad
