Ok I’m new to this so I’ve tried reading through threads but I can’t seem to get an answer on this. I have a 2022 FWC Hawk equipped with the following:
1 x 160W I believe overland Solar panel although I can’t find any docs from FWC to be 100%. Plus my foot is in a cast for a couple weeks so getting on the roof is a challenge. https://www.overlandsolar.com/collections/off-grid-cabin-solar/products/overlander-160-etfe-semi-flexible-solar-panel-with-top-mount-junction-box
an Overland Solar MPPT 100w/15A Controller
Zamp Portable Solar Plug
2x6volt batteries 224 AH
Here’s my question. I found a 100w Massimo Portable Solar Panel on sale at Costco for 50 bucks so I snatched up 2 of them. Specs are near the bottom of this link. https://massimoelectric.com/solar-panels/.
Aside from wiring, polarity, 5525 to SAE connectors etc, I was wondering if I can attach both panels via a Y splitter to the Zamp Solar Plug. If not I’ll give the other to a friend but thought I’d give it a shot.
My concern is that the MPPT controller (which I believe is a rebranded Victron) says it’s got a max PV Short Circuit power of 15A. If I add up the specs for the portable panels and roof panel I come out to about 17-18A. Voltage I am well under 100 max volts. Does anyone have any real world thoughts on whether 18A would damage my 15A controller? Just seems odd to be so far under the voltage req but be past the current max. Is my math or understanding of how this works accurate?
Portable Solar Short Circuit Amps = 5.68A x 2 = 11.2A
Overland Solar Panel Roof = 6.27A I think
Total about 18 to be conservative.
MPPT controller doc states 15A max PV Short Circuit. https://www.victronenergy.com/upload/documents/Datasheet-SmartSolar-charge-controller-MPPT-75-10,-75-15,-100-15,-100-20_48V-EN.pdf
Any experience with this?
