Now you tell me :) Seems like good advice.

I do have a ladder and believe it to be OSB roof. Can't believe I never heard of well nuts, I'll check them out. My roof will be redone by RV Armor after panel installation so no need for eterna bond tape this time around.

Hi All, I have a GD 22MLE trailer that comes with a 165w panel and small scc.. Very cheap battery installed by dealer. I'm planning to upgrade, adding 3 200w panels connected to a new scc and Li battery. I was going to pull out the factory panel but now I'm wondering if there's benefit in...

Looks like you're using the Vmp / Imp values in the calculations which makes it more 100/50 friendly than using the Voc / Isc like I was doing. I thought using the Voc / Isc was the right way to account for worst case scenario on a faulty panel. Assuming I have that wrong it's not the first...

Sure. The factory scc is the furrion FSCC30PW-BL. No idea who makes it. It's a 50/25, lithium capable. Battery System Voltage 12V/24V Max. PV Power (Pmax) 300W Max. PV open circuit Voltage (VOC) 70V MPPT efficiency ≥99% ECO mode draw current <1mA Min. Battery Voltage for Charging 3V Max...

Interesting option. It mentions interrupt Capacity:1,000 Amps, is that high enough? Also some reports these breakers aren't accurate and pass more current than they're spec'd for.

Thanks mister Sandals. To clarify, the existing panel is 165w so combined with one of the 200W panels looks like it'll be a little high or right on the edge (365W / 14V = 26A) fpr the original CC as it tops out at 25A. Are the specs on the 2 different panels close enough to combine in 1...

I went with the fuse holder and BLF fuse listed in my first post. We'll see how it goes...

Planning to install a TS-30 transfer switch and run the charger directly to the shore power at the ATS, bypassing the power center. This should prevent the charger from running when the inverter is powering the trailer. That circuit won't be protected so I'm looking for a good fuse/holder...

Haven't decided on the brackets yet but they'll be screwed and/or anchor bolted in. It's thick enough to walk on, though it does flex, so expecting the panels to stay. It's a TPO roof so not planning on taping. Sounds like you're running 2 separate solar systems then. Though about that but...

My comptroller has put a cap on the cost of this project and I'm already over so won't be able to buy a 4th matching panel. Not sure how to tell if the 2 different types of panels are close enough to mix in 2S2P. Can you tell from the specs // The factoy panel specs are Maximum power...
