I have the MPPT 100/20 48V Solar Charger up and running, charging a 48V Li-Ion battery pack.
The OCV for Panasonic GA cells (13 in series) is going from 42,3V (SOC = 7,5%) up to 53,9V (SOC = 97,5%); This is the working range.
Now I am trying to find the best settings. Could you please help me with that!
How should I set
- absorption voltage
- float voltage
- equalization voltage (really needed for Li-Ion?)
- Re-Bulk voltage offset (what is it for?)
- Absorption duration
Thank you very much in advance!
