First full weekend after having changed my batteries a few weeks ago.
I replaced my acid-lead batteries with 3 SS EG4-LL and every time I get to my cottage, they are always fully charged. This is the first time I have the time to spend the weekend there and do some testing. On Friday, I discharged my batteries to 68% and when I woke up on Saturday, it was very cloudy. I noticed some charging during scattered periods of sun but decided to go do something else waiting for the sun to come out.
In the afternoon, now under a bright sun, I went down to look at my batteries. They were still below 70% and discharging (a little) while my solar charger was only giving a couple amps, just what’s needed for my iternet and some other stuff…. I decided to shut everything down and when I powered up my gear, the batteries were charging with the 20 amps given by my charger (ok, maybe not full sun…)….. Saddly, I had to go and didn’t have time to check anything else.
What am I missing?
My charger is an Epever 4215BN with these settings (partial list):
Charging Limit Voltage: 28.8v
Overvoltage Reconnect Voltage: 28.8V
Equalize Charging Voltage: 28.8V
Boost Charging Voltage: 29.2V
Float: 27.2V
Boost Duration: 180
