Seeing here that my last post was three years ago makes me pondering about procrastination
So, last November I finally put the system to work. The PIP-2424MSE1 is fed by 4 460w mono panels in 2s2p configuration (will ask an advice about this later). From November to late February, it charged a bank of 60p7s, then I replaced it with another 80p7s bank and this month I upgraded the 60p to 100p and added them as a second bank, giving me around 9kw of storage.
More work to be done in the layout of the inverter and fuse boxes and replacing the MDF trays with something less flammable, not to forget finishing the DYIBMS, based on Stuart Pittaway's project.
Now, I have a problem. The PIP doesn't want to charge over 20A, despite having a 40A MPPT.
In the manual it says that the total amps (40A) should be divided by the current provided by the panels (10,6A), giving me the number of panels in parallel. From what I understand, this is correct for the PWM charger, but not for MPPT, which is able to take a maximum of 20A (two in parallel) at 80-90V (two in series) from the panels and transforming that to 24-28V and 40A for the batteries.
I triple checked the menus, everything looks fine.
My last option is to put the panels in 4p configuration, but I don't really understand.
