SmartSolar MPPT CC Manual Question

Hi,

Looking through the SmartSolar MPPT CC manual there is a bit I don't understand.

On page 7 there is this comment...

48V battery, mono- or polycristalline panels, max PV voltage 250V:
● Minimum number of cells in series: 144
(4x 12V panel or 2x 24V panel in series).
● Maximum: 360 cells (10x 12V or 5x 24 panel in series).

It's the last line I don't fully understand.

I'm looking to use 30Vmmp, 60 cell, 295w panels on a 240V/100A charge controller, so how many panels can I connect up together in series.

I'm probably being very dumb here but a explanation would be gratefully appreciated.

Many thanks Tony

Hi @Tonyat59,

It will vary on a few conditions, the best thing to do would be to fill out this MPPT sizing calculator:
