    Solar Configuration Review/Questions

    Thank you for the feedback! The switch I had purchased to use was this one https://shop.explorist.life/shop/all-products/solar-isolator-disconnect/ which seemed to fit the need, but I wonder now about shutting off under load and if that might cause damage to the switch or elsewhere? I assumed...

    Solar Configuration Review/Questions

    Thank you! I happen to already have the panels as they were the perfect size for my van. I'm pretty close to starting to assemble my junction box, just sourcing the last components. Thank you! Much appreciated! I've got things fairly close now and have most of the components for my junction...

    Solar Busbar DC Voltage Limit

    Thanks, that is helpful and confirms what I was thinking that at 70V (and potentially higher) when there are no amps flowing through the busbar I should be okay.

    Solar Busbar DC Voltage Limit

    I'm working on creating a junction box for connecting my 3 panels in parallel. The box will fuse the positive side of each panel before connecting to a busbar. My plan had been to use a Victron 150A/70V busbar (picture below). The max DC voltage according to the specifications is 70V. My panel...

    Wire Connection Methods For Vibration

    I originally had planned around MC4 inline fuse holders, but after reading a bit more on them and learning that there was only truly one MC4 (Staubli) and then a rest of variants with potential for issues from corrosion to overheating I decided I'd rather stick with something more reliable like...

    Wire Connection Methods For Vibration

    Thanks Mike, I should have mentioned it's 3 panels, so as you mentioned I have to run the fuses. Here are the panel specs, I have 3 of these on the roof of the van. Panel Specs (Panasonic) Max Power (Pmax) 325W Short Circuit Current (Isc) 6.03A Open Circuit Voltage (Voc) 69.6V Maximum Power...

    Wire Connection Methods For Vibration

    I'm working on creating a simple junction box for my solar panel setup on my van. I've got limited height under my panels, so the box is slim and just a little too short to use a din rail type midget fuse holder (2.3" tall fuseholders vs. 2.1" tall enclosure). So instead I started looking into a...

    Solar Panel Fusing Options

    Looked further into the options above and the touch safe fuse holder is unfortunately too tall for my junction box (Interior height of about 2"), so I started looking into the the Littlefuse 3 fuse holder blocks and they will fit. My question has to do with the wire connection type for these...

    Solar Panel Fusing Options

    Thanks! Looks like a viable option for sure, I just need to do a little digging on the dimensions to see if I could pull off fitting a din rail and one of these in my enclosure. Cool! I hadn't seen these before, so this might be an option for a lower profile version in case the DIN rail fuse...

    Solar Panel Fusing Options

    Hello, I've been trying to come up with a solution for how to fuse my 3 panels in parallel. My original intent had been to just use an MC4 3 to1 branch connector with inline 15A MC4 fuses on the positive side. My 3 Panasonic panels use 12AWG and I'm running 8AWG after the branch to my disconnect...

    New Van System Planning Help

    Finally getting close to actually wiring this as I've just finished the roof rack and the panel mounts. After enough tinkering and seeing what space I actually have I'm leaning now towards ditching all of the MC4 connectors and just using a couple of bus bars inside my external enclosure...

    Small Size High Quality Combiner Box Options

    Running 3 Panasonic panels in parallel to make them work with my 100|50 Victron MPPT (3x 325W). I had considered cutting off the factory MC4 connectors and crimping the connections, but thought if I left that as the only MC4 connection it would make removing a panel easier if I need to at some...

    Small Size High Quality Combiner Box Options

    Hello, I'm working on my solar system and had a different thread going with some other questions. Here is the link for reference https://diysolarforum.com/threads/new-van-system-planning-help.13073 My question for this thread has to specifically do with looking for suggestions for a high...

    New Van System Planning Help

    Thanks, I've thought about it a little more and now I'm thinking maybe given my rooftop space constraints that I should instead move the PV combiner box inside the van. This would require running each panels wires about 10 feet into the van and then joining. I would keep the MC4 connectors...
