Adding Solar to Sprinter RV

The coach (WB Navion) is equipped with: (2 * 100) Zamp panels on a 30A PWM Controller, (2 * 125 Ah,) Lithium Batteries. and a Zantrex 2KW Inverter/Charger.


So here's my plan:

1) Connect the (2 *100) Zamp panels in Series and feed them to a Victron MPPT 100/20 Controller.

2) Add (2 * 210) Newpowa panels (Voc=39.6V, Imp=6.24A) and feed them to a Victron MPPT 100/50 Controller.

Did not want to mix panels, so opted for separate Controllers... Please ignore the "extra" stuff: Lynx Distributor, Smart-Shunt, Cerbo GX, and GX Display/Touch.

Question: Is 620W of Solar overkill for this system?

If you have any size inverter at all there's virtually no amount of solar you can stick on the roof of the thing that will be overkill.

If your inverter usage is light you'll probably be happy with that.

I've spent a fair while trying to figure out how to get 1200w on top of a 2x3 meter roof space for like 1500w of inverter load.

It's doable by the way. You just have to be real clever about it and AND stack panels to be slid/pulled out when parked.
