I have a 24v battery/system. Is all of this still relevant? I have decided to run them in parallel anyway as it completely removes the issue, plus with a 24v battery, the panels would have to be running very low to not be higher voltage than the battery, plus I'll never be in the cold for very...

In case anyone finds this and has a similar inane question :) I was able to identify the cable in the pic above as the actual negative battery terminal, so that will do just fine and is very easily accessed. This video is a bit older, but shows how to access the battery in a transit and seems...

My experience with overkill cust service is also over the top excellent.

Well, MisterSandals, you have the solution. Too bad I didn't check this before I left Jacksonville yesterday. Now in Tampa area for a couple weeks. Hopefully I can find someone similar in this area. My search of craigslist was terribly UN-fruitful. There is no category for solar panels and...

This is what I was referring to:

I'm new at this but have a pretty solid basic understanding. Troubleshooting seems to be the weakness. Finally connected my 24v 280ah battery to the electrical system in the van. All the 120 stuff works as expected (except the transfer switch but we'll leave that to another time). Problem...

Ok, I decided to connect my 12v power supply I use for testing on the bench to the dc panel pos & neg terminals. Turned off the battery completely first for safety sake. When I turned on my power supply, every damn thing came on and worked perfectly. So there's that. Checked voltage and it...

Voltage running into converter is 26.86v. Coming out is 12.2. I did have to use butt connecters to connect the device to the lynx distributor. I'll have to undo and redo that, but I am one of those ridiculously meticulous people, so my money is on that not being the issue, but, only one way...

This is the device I am using...

Reading comments, I think it is supposed to be putting out basically what it is. I'm not sure what else to purchase? Anyone have any idea?

Anyone ever come across one of these: Victron Energy Orion 24/12-Volt 70 amp DC-DC Converter Non-Isolated, High Power https://www.amazon.com/Victron-Orion-12-70A-DC-DC-Converter/dp/B01BF5BQLA/ref=sr_1_2?keywords=24V%2Bto%2B12V%2BConverter&qid=1679376659&sr=8-2&th=1 It says adjustable output...

The converter is a very simple device. input is a wire from lynx dist. attached using butt connectors. Output is two wires using 3 way wagos. If the wiring is an issue, it is a bad butt connector. I'll definitely check that before replacing the usint.

Sorry Chris, but you lost me with this suggestion... You mean insert a battery and use the 12v feed to charge it and use the battery to power the DC 'stuff'?

Ah, so the voltage should NOT have changed when the pump started running? Yeah that makes sense given I was taking the measurement at the input terminals. I don't think I understand how that would help me since the input being too low to start with, but if there is a wiring issue with the...

Ok, Chris, I'm following. I do have a victron 12|24 dc to dc charger already. I'll have to check the total amperage. I figured 40A was going to be more than enough...

I'm such a moron. The pump came on when I inserted the fuse because the damn switch was in the on position. All my issues should be solved so easily. All I have left to try is redoing those butt connectors. Fingers crossed...

Thanks again MisterSandals. Removing panel from the search helped a little. Not much in the area, but a lot of solar companies so, fingers crossed...

Ok, some sense is coming of this, perhaps. If 26.9v is what is coming out of the 'switched power supply', then the batteries will not charge much beyond yet, correct? Yet, when I run the engine, the dc-dc charger inputs 12v because the alternator is putting out higher volts than the battery's...

Not to hijack this thread, but I am in a very similar situation wanting to use two panels on the roof of my van and the VOC of the xl 450w-ish panels all dancing on the edge of 50 which is cutting it too close for my Victron 100|50. I was going to go parallel but most people say to go series...

This stuff has me feeling like an idiot, although, following this chain of events in the attachment, I don't think I will ever understand this stuff as it seems to defy logic to me. Does this series of steps add up to you? The worst part of being new with something is the lack of confidence to...

I want to take advantage of the Ford CCP. I'll run the positive 8 awg cable about 8 feet to the rear of the driver's seat where I'll add a 60A breaker and from there connect to the CCP. I'll run the negative cable directly to ... Not entirely certain where to connect this. I was hoping not...

I included the cell readings in the attachment. They are all within .02a, so, pretty balanced. It will charge at 1a for a while. I will plug it back in and see when it shuts off completely. The BMS seems to not be 'accurate', but hard to tell, really. I also included a link to the charger I...

For the record, I received my new Victron 12-24 70A convertor that defaults output at 13.2 and I just connected it and everything worked as expected. My research found lots of evidence that the simple converter I had was supposed to be outputting 12.2v and that simply was not enough. If I had...

The charger has no setup one way or another. Only the BMS can control the amount of incoming amps AFAIK. I guess that is ultimately the issue at hand... TYVM for the input!

Mike, I had hit the discharge to disable it while charging. I didn't have to but I just did. The electrical system is not running anything important at the stage. My thinking was that the BMS was limiting the input from the charger due to the cells being 'mostly full'. But I want to get them...

Pretty sure I need to top balance my battery cells. They won't seem to charge much beyond 27.5v. Can that be done with with a 24v 30A charger? My bench charger is only 60A 5V and I'd prefer to use the much faster one if it will work, but it has no controls. This is it...

I just went for a quick drive to check the dc-dc 24-12 15A charger. Input on BMS gui was showing 12A. Wow, so confusing. Just plugged the charger back into the shore power and showing 1.8A. Man, that is confusing to a newb like me! Checked charger and 26.9v coming out and checked battery...

I am in a van moving southward. Presently in Savannah GA heading to Jacksonville FL. I have a 24v battery system in the van and need a large solar panel. I always wondered why no one ever seems to use the large ones and assumed it was the size and hard to fit with a maxair fan and the like...

Thanks for all the info Mike. I was hesitant to buy another 24v charger since I thought I already had one that didn't do the trick, but mine seems unable to be adjusted higher than it is. It does have the adjustment, but it is maxed which is the root cause for all of this. Plus,. it is a...

Yes, I was thinking 40v at the very minimum. Most of the panels I have spec-ed were 48+ so that was what I hoped to get. I'm in Tampa/Clearwater area for a while and there are a great many solar installer companies. Surely I can find one. I'll have to check craigslist but I am not sure a...
