Rich Solar & MPPT Size

MPPT controller selections?



I have 6 Rich solar Max 200 watt panels. VOC is 45.4 and ISC is 5.83. Does Victron have a MPPT that will handle this load? Series or parallel?

What battery voltage?

With a VOC of 45.7 should be offset by around 15% or 53V to compensate for average low temp exposure, or find the actual low temp compensation for the area you live in.

Victron has 150V mppt capability in some of their controllers, and 75 v in others, so you could put all 6 in parallel in that one… but that would be 34.98A capable output, and would NOT be a high enough voltage for a 48V battery. So suitable for 24 or 12v only…

Yes, but to specify the controller, the voltage of your system is needed, is it a 12 or24 or 48 volt system?
If its a 12 volt system then a 100 amp rated controller is needed.

Either a 150/100 or 250/100 could be used. A complete series connection of panels would, taking into account cold operation, exceed voltage rating.
For the 150 volt unit, 3 strings of 2 series panels, then connected in parallel, for the 150 volt unit, 2 strings of 3 panels in series , then in parallel.

A 24 volt system would need a 50 amp controller.
