Hello
Suddenly my Smart Solar MPPT 100/15 has the following problem
The batteries goes up to 28.8V (Bulk voltage) goes to absorption (1A)
(2x12V lead acid batteries)
but applications shows me that goes only 0.2A to battery after some minutes goes to float which should be 27.2 but drops down to about 26.6 because the current for load comes from the battery... and after some second goes again to initial load and so on...
This is strange because the current for the load before came from the solar panel...
I have a 280W solar panel and load is only 85W when charging batteries 130W ....
So what could be the problem?
Defect batteries?
Batteries are normal auto batteries 75Ah each acid, calcium
Should I initialize an equalization cycle? (Never done until yet, they are about 4 month with this setup and 1 year in total use...
