Thank you @Hedges and @HRTKD , you've given me a path forward for tomorrow. I feel optimistic that you've guided me toward finding the culprit and an easy fix. I'll check the voltages versus the app, check for resistance everywhere, replace something if I find something out of whack. I'll...

When I disconnected them and charged them each on their own, they both started at 9.8v and ended at 13.37v, so I think they are both behaving the same. I have them back on the solar charger today with no loads, but the 3" of snow on the panels this morning means they're not generating any current.

My system is (or was, I dismantled it): 2 100w HQST solar panels in series 50' solar cables victron MPPT 100 | 30 SCC 2' 12 gauge solid conductor wires, positive fused with 40 amp automotive spade-type fuse 2 battleborn 12v 100 Ah batteries wired in parallel 6' 2 gauge 130 degrees C stranded...

Yes, that push button "light bulb" switch turns on or off all 4 ports simultaneously. What I've never understood is why they sometimes turn on when I don't expect it. There may be a mode accessed with the switch below it that runs them like a security light or something. The documentation is...

I need one of these portable evaperative coolers. Could you share which one you use?

Haven't seen a video but Fiap in Germany has several kits. A lot larger scale than hummingbird scale! If your German is not good you can select other languages on the top of the page. https://www.fiap.com/wassergaerten/pumpen/aqua-active-solar.html

You may want 2 fans, 1 in front and 1 in back so you can have good airflow thru the van, one for intake and the other for exhaust, if you have room on the roof for 2 holes. You left off your cooking appliance(s) such as induction burner, and/or microwave. I have a 3 qt instant pot and make steel...

Great, if ever I am in the UK now I know where I can charge my phone! That's an awesome leap from 1.5kW to 22kW. My utility only permits new systems up to 50% of prior year's use, sigh. Looking forward to the pictures to make me even more jealous.

This is great, that article took me to a spreadsheet they published where I can input my array and it tells me if it's acceptable for the SCC I have, including the 30% over-panelling. Thanks!

Yes, thanks, that helps a lot! I knew I wasn't following what was being said. Learning a lot of terminology on here, among other things!

Curious how one would over panel in this instance. Lets assume they're starting with 2 100 watt panels in parallel. Later upgrade to 2 additional 100 watt panels so the array is then wired 2S2P. Adding one more 100 watt panel would get you to 25% over panelled, but how would you add 1 more panel...

Here's a resource I thought I'd pass along. Stopped in this week to make sure they were real and to pick up some solar wire for my new project. They had stacks and stacks of solar panels for 20 - 33 cents a watt. They have lots of other stuff too. Looks like it's a warehouse for a commercial...

Not enough details to really come up with the right thing, but how about this: 12v portable compressor fridge/freezer (single compartment, run as fridge) Truckfridge TB51A (1.8 cu ft / 51 l) $599 2 x 100 watt solar panels HQST wired in series $162 for the pair Renogy Rover Elite 20A MPPT Solar...

This article covers how one guy did it. I think using MC4 connectors would have been the better choice for his electrical connections. Finding hinges with countersunk holes and using flathead machine screws might have avoided the clearance issue. But overall a very nice build...

You might look at window sash locks to latch the panels closed together. You could look at slide bolt latches (barrel bolts) to secure the two panels flat and open. Hope you show us some pics when you finish!
