Nice. I'd like to do the same. Side question: I have 6 40w panels that are each rated at 2.3A 17.1V. Wondering how i should connect them to maximize the charge. Was thinking of wiring them all in series to maximize voltage, or to do them up in a 3S2P configuration to get the amps up.

Do you have a second charge controller for the ground panels?

I'm leaning towards the 2S3P option as well. My roof deck is 25' long, so i'd be able to space each series pair out decent enough. My next question is which Victron MPPT is right for my needs. I'm thinking the 150/35 should suffice, but when i use the Victron Calculator it suggests the 150/45...

Would there be an advantage to instead using 6x100 watt panels, paired in series and then connected in parallel?

Here is a link to the panels: https://www.amazon.ca/dp/B00ZOOGVOQ/ref=cm_sw_r_cp_apa_i_3MQCQBS1BW3ERB142T37 I'm going with parallel connection due to shading issues on various campsites.

Rated power: 195W Voc: 22.41V Vop: 17.9V Short circuit current (Isc): 9.87A Working current (Iop): 8.89A I'm going to get the victron 100/50, hooked up to 2 6v t105's.

9.87A

My setup will be 3 195 watt panels on a small camper trailer. Do you think the branch connectors will suffice? They are rated at 30amp.

So i've been doing some research on connecting multiple solar panels in parallel, and most people seem to advise using a combiner box rather than MC4 branch connectors. But i've also seen quite a few youtube videos that show the MC4 connectors. Also, Renogy sells a 400w kit that uses the MC4...

I'm looking for some advice regarding my battery and solar setup. I've got 2 Trojan T105 6V golf cart batteries, and 6 40 watt 2.9 amp Coleman solar panels. In the past I've been using the Coleman solar charge controllers (2) that came with the panels, but am concerned that these may not be...
