Thanks

Thanks, will try and separate and see what happens

Hi, thanks a lot for the prompt feedback. Negative feed is in fact from the bottom battery, see photo.

Hi I have 4 x Dyness B4850 batteries installed in parallel with a Growatt SPF 5000 inverter. Two of these batteries about 3 years old with two newer ones. Newest, about 3 months old installed as the Master, with DIP settings at 0110, all the others at 0000. Second battery, adjacent to the master, only charging up to 75% (three green indicator lights) and also discharging quicker that the remaining batteries, see indicator lights on sketch, Master at the bottom. Please advise as to how to rectify. .

Hi I have a Growatt Model SPF 5000TL HVM-P which was installed about two years ago. (Feb 2020) I had 6 x 360W panels installed initially and was achieving a max PV charge of between 1900 and 2100W during peak sunshine periods and decided that I'd like to increase this max PV charge in order to decrease the amount of time required to recharge my batteries, i.e. 3 Dyness 4850's I then had an additional 6 x 335W panels installed during the first two weeks of March 2022. I am no professional on electrical issues but my common sense and basic maths told me that my system with the solar panel capacity now doubled should give me approximately double the PV available max W at between 3800W to 4000W. To my surprise my system however now is only able to achieve about 3000W which to me does not make sense. Does anyone have any advice for me please as surely I should be getting at least an 80% increase in Max PV W following a 100% increase in panel quantity.
