Just got my installation done yesterday! Fun to look at and check the statistic on the app :)
My system is 100/20 mppt, 2 x 225 ah 6v, 295w solar panel and bmv712 installed in a sprinter van
Yesterday got the charger to charge and everything looked fine, but this morning I went to work parked the van under the sun, it was in bulk mode at that time. 8 hours later, after work I come back to the van, check the mppt status light it shows it’s in absorption, which I though was normal. Then I check the app and it shows it did went thru the float mode for a part of the day...
So I drive back home, once there it was now in float mode, thought it was weird. Went inside my house get a snack, and now it’s back in bulk mode
Is that normal?
I thought the cycles was to happen one after the other and it was not going to cycles thru them. Maybe I’m confused...
Just to make it clear, I have a 12v refrigerator hooked on the system, duty cycle is about 15minutes and it roughly draw 50w while on
Also I have checked the plates they look clean without sulfatation
