hi.
i have a epever up-hi 3000 hm10022 hybrid inverter/charger.
Li-ion 3.7v/cell 7s 24v/270A battery
1000w solar
recomended settings from dealer:
Boost 28,7v
Absorbtion 120min
float 28.5v
Boost reconnect 28v
today, its sunny all day, charging in boost from 27.5v .. . all good..
then when it starting to get close to boost voltage (28.7v) i wanted to pay attention to learn some about the behavior of the CC .. at 28.65 the amp started to be lower and lower until about 10 Amp. Then it hit 28.7v, and then BAM, the amp went to zero and CC goes to Float ! ? ... Interesting... still lots of sun.. The Boost/float setting works, battery is ok , but where is the Absobtion time??? I was expecting to see the amp slowly decrease until almost Zero amp, AFTER the 28.7v . then go in fixed voltage mode at 28.7v and ABSORBE! ,- and then go to float mode... The amp went from like 15amp to 10 to suddenly zero in like 10 min.
Am I missing something here?
