Hi there, a panel which is not in the mppt calculator…., and I don´t know how to calculate. 20 panels Axitec AC 500 TGB/108WB on 2 mppt´s 250/100

Right now for only a couple of days, we want replace older panels in an existing 24V offgrid, with this new panels, and 1 mppt 250-100. How much of these panels can I connect?

Waiting for the new 48V batteries coming in 2 weeks. Then the intention is 20 panels 2 mppt´s. Is 2 strings/5 panels for 1 mppt ok?

When in the calculator enable custom panel settings then input the details from your panels datasheet / label and do the calcs.
