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...

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...

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...

Working on installing the solar portion of my electrical system and wanted to get some feedback. I've been reading/referencing the https://diysolarforum.com/resources/fusing-wire-sizing-guidelines-for-solar-panels.143/ to help figure this out. I've attached the panel specs as well as my wiring...

Trying to figure out the layout of my DC - DC charging circuit in my van. I have 4x Orion 12|24-15 Smart chargers, they are fed by my vans upfitter connection point capable of 175 amps. I'm going to limit the Orions to 30 amps max each, so I won't draw more than 120 amps from the 12V connection...

I recently purchased (2) BigBattery 170Ah 24V battery packs for my camper conversion project. They'll be delivered in the next couple of days so I'm looking for any advice/input on recommendations for testing them out and making sure everything works as it should. Here is my basic list of tests...

I have a dead Bluetti EB150 that I started a thread on and had a discussion around troubleshooting. That led me as far as getting it taken apart and some testing, as well as going back and forth with Maxoak on what to test next. The last place I left off was Maxoak telling me to test the...

So I've read pretty much every thread I can find here about the SOK and Big Battery Powerblock options, along with watching Will's recent video on them and reading through this long thread on Big Battery getting caught making false charging claims (located here for anyone who hasn't seen it...

I'm in the midst of building out my camper vans electrical system and I'm getting closer to trying to sketch out some basics for the solar system on the roof. Here is what I have so far for a basic system config (minus wires/fittings/etc.) Panels- Panasonic VBHN325KA03 325 Watt (x3) Controller-...

Trying to narrow down possible plans for my electrical system build for my camper van conversion. I've spent months reading and searching these forums and watching videos and have an okay baseline of understanding, but need some help figuring out where to go next. Here are the requirements I'm...

Hi all! At the beginning of this year I purchased an EB150 through Amazon. Upon receiving the unit I plugged it into the charger and all was fine, display came on and it charged up. Then I plugged a small mini fridge into it for a test. The panel read something like 200w for the first couple...

Hello! Thanks to Will and all the helpful members of this forum! Been learning so much! I've been toying around with building a solar generator for about a year and finally making some meaningful progress towards this project. Been watching all of Will's videos and think I have a handle on what...
