I am using two AGS 100Ah battries (in series) with this inverter. I came to know latter about the Pheonix UGS series from this thread when I already have purchased the setup. Moreover Pheonix brand is not available in my city.
Inverter automatically set the charging rate by analyzing the status of batteries but I set up the charging rate for wapda at 10A and leaves at default (i.e 50A) for soalr. Inverter has 3 step charging and I analyzed the charging step of inverter as when batteries are fully discharged inverter provides 15A current for some time as the level of batteries increases level of current decreases to 7A and stable. When batteries voltage reaches 26V, level of current further decreased to 2.5A. After batteries fully charged level of current becomes 0.2A to 0.3 A.
I am also planning to add two more batteries of same brand and same capacity in parallel to already batteries. What do you suggest should I purchased the same or Pheonix UGS series??
