Here’s something that I have ‘googled’ to death and still don’t know the answer. I have also passed the problem back to Offgrid Power Solutions who are still investigating and I await their response, but in the meantime, it’s driving me mad not understanding.
Four days ago, I had fitted:
One solar panel, 185w to add to existing 100w
Victron MPPT controller
Fogstar Drift 280a
B2B
12/1200 Inverter
Drove home and battery 98%
Since then, the battery has slowly diminished despite a good amount of sunshine (although that is irrelevant because the new panel is soooo efficient and is providing reasonable power even with no sun and some rain).
Currently showing 61% on the app, although the Sargent control panel in the motorhome indicates that both batteries are 100%
The only draw is the newly installed inverter, only 0.8a per day (turned it off this morning, now there is no draw registering).
The solar charger has gone though Bulk, Absorption and Float each day (see attached picture).
BUT, it is going into Absorption too early and then Float when it is far from fully charged.
I have researched this so much I now have a much greater understanding on how the system works/is supposed to work, which is a good thing but I have always hated not knowing or understanding anything in complete detail.
So why is it doing this? With so many self builders out there like Lenny etc, someone must know
