How much PV can I attach to a Victron 100/20

A Solar power question. I have a Victron 100/20. Manual states Nominal PV 290W, Max PV current 20A and Max voltage 100v.

I have 2 house panels which are 275w, 8.71A and 31.6V. Would it be better to connect in parallel giving me 63.2V/8Amp or Serial to get 31.6V and 17.42Amp

Also either way i will get 550w will this be an issue with Nominal PV being 290W on the 100/20?

You want both ;) if facing the same direction. If facing different directions you might be better off in parallel.


Serial at 63 V, 8A. Nah no worries. It will limit itself to 20A towards the battery. If you have 24V batteries it will even reach the 550W.
