Victron SmartSolar Charge Controller MPPT 100 20 Share your configuration

[Chris O]

Hello Victron Smartsolar Charge Controller owners. I would love to see your panel and battery configuration if you have the MPPT 100/20
I am trying my best to come up with a panel configuration that would work with the MPPT 100 20 that is overkill for 12V battery but able to do 48V (charge at 58V) battery too. Even if I need to add a panel or two when I switch to 48V

Share your panels manufacture, model, specifications, wiring configuration and any other details please.

I started with 100 watt panels, don't remember the details but they were about 22VOC. Ran them 3S2P(600w) and overpaneled 4S2P(800w).
Now I have 2 of these in series on a 24 volt system.

Thanks!! I went on Victron's WEB tool and it has this panel and comes up perfectly for 24V. Thanks for sharing. I tried Victron's too to change battery to 12V and 48V and no configuration of these panels with work, only for 24V. The Victron 100 20 is just too limited. Thanks again for sharing

I added a 100/20 and a "redneck" ground mount to my existing system to gain some extra power in the winter.
2S NE Solar 370W panels, ~40' of wire back to the Victron.

are you charging 12v, 24v, 36v, or 48v?

And that's charging a 48v system right?

I have two charging a 48v AGM bank.

2x 2s4p 72cell arrays, 1.52kw & 1.43kw (1.16kw net charging power for each 100/20)
