Yeah, me too. Mine was a 200A Smart BMS with Fan for my first build. I didn’t know all that much about BMSs. It too has been running flawlessly for the last 2.5 years so keeping my fingers crossed ?. I did turn off the Daly balance circuit and add a 4S-5A Active Balancer which keeps cell Delta...

I like working on things as much (if not more) than actually using them. We’ve had several RVs, a Cessna 172, a drag car, and a few motorcycles. I really enjoy working on them to understand their design, capabilities, and potential. Only airplanes were a close second to my wife. I really liked...

@Rednecktek - Thanks again for your insight! I have confidence in the DIY I built because,,, I have used it since I built and know its limitations, i.e. I learned a lot! You‘re right (of course) about prices. In 2021 my DIY cost around $550 all-in with cells, bms, cables, lugs, bla, bla, bla and...

I’ve been reading through this thread and looking at the included links. I have a 12V 200AH LFP in my truck camper. I built the battery in July/August 2021 and it has been performing admirably. The wife and I consume 15 to 50 AH daily depending on the time of year. My current solar system of...

My, my, my. My search skills really, really, stink! Thank you very much. Dave

I bought an inexpensive Rivnut tool on Amazon years ago and used it on my Renogy tilt brackets to get rid of those stupid wing-nuts. I hadn’t thought of using them for the panels. Dave

I had a narrow and short Lance 1575 TT before. I put 2S strings on either side of the AC specifically for the reason you mention and it worked fine. I also had a portable setup for the same purpose and kept it. Thanks, D

My search skills are not very good. I tried different iterations of: effects, shading explained, etc., and couldn’t find it. Will is a pretty sharp fella and I would like to read up on the discussion. Could you provide a link to that thread? Thanks Dave

Since my controller can easily handle a Voc of 88 volts (and I already have everything I need) I’m going to try 2S2P for a while. If that doesn’t work for me then “it only costs a little bit more to go first class.” Thanks everyone, Dave

I don’t participate much on here but just about everything I learned about solar comes from diysolarforum. Thank you @Rednecktek and @Rocketman for sharing your knowledge and @HarryN for asking such a pertinent question. D

I have a second controller (Morningstar 15A mppt) from my old camper that I put in the battery compartment. I made a 24V 120W portable panel (2P 60W). I went with the higher voltage so I could use smaller gauge extension cables. Since Watts are Watts and I don’t need to worry about shade I might...

Thanks for the reply. Running 4P mainly to ameliorate the effects of shading. Shade is inevitable at some point during the day when boondocking in the forests (typically Arizona and Utah). I do winter in the desert for a while but mainly spring through autumn travels. Going 4S would exceed the...

Forgot the photo:rolleyes:

I’m mounting an array on my Truck Camper consisting of 200W, Voc = 44V and Isc = 5.75A panels wired 4P; total Isc of 23A (EDIT Amps not Watts) Is it okay to use 4x1 50A ”Y” connectors (photo) an all MC4 run,,, or should I wire the panels through a roof-mounted junction box with minimal (if any)...

My sincere apologies for the late response. It was as @Bobert suspected as being a problem on the battery side. In my case it was the cheap ($12) 40A inline circuit breaker between the SCC and the battery that had poor continuity/bad contacts. I rapped on the CB with a small hammer and the...

Thank you for your reply. ? That’s what I thought too (considering the load from the pump). This was just the first time in almost a year this “issue” has shown up. I almost always dry camp w/o hookups and we do consume a bit of power especially when we run the furnace. I keep a close eye on the...

Thank you for your reply. I understand the SCC battery output would depend upon battery charge, however, SCC panel output has (had) always been 250+ watts in full sun when charging regardless of battery SOC unless battery voltage was above the absorption setting then the SCC would change to...

I am spending a week in northeast Missouri this Memorial Day visiting family. My truck camper system is 2S2P Rich Solar 80W CIGS (320W total) running through a Victron 100/30 MPPT controller charging a home built 200AH LiFePO4. I currently have the SCC on the default LFP setting. I monitor the...

DIY for sure (IMHO). Many years ago I had a camping trailer that was very limited in cargo carrying capacity. I prefer boondocking in the woods several days or a few weeks at a time. I originally had two 100AH AGM but couldn’t carry enough solar to keep them topped off. I carried a 2KW Honda...

:LOL::LOL::ROFLMAO::ROFLMAO::ROFLMAO: Don’t forget to add those to your living trust to keep it fully funded!

:oops:You guys paid too much. :ROFLMAO::ROFLMAO: These only cost me 30 cents a pop. I would have given you one except the postage would have cost more money than the diode was worth and USPS shipping is slower than Amazon’s...

You might check the Corporate Corner. There was a post earlier today about a store.

I would call Winnebago or join a Winnebago or Navion specific forum. I have a Lance and can get the engineering CAD drawings specific to my year and model. But I agree with all the others talking about the fragile nature of roof materials and/or membrane outside of a structural metal roof. I’m...

Perfect!!! Thanks @pvdude !,!,! Other than my holes in the roof, because I had some warps in the roof, that’s exactly what I did. Perfect explanation. Dave

Well,,,, it certainly “LOOKS” to be adequate based on that PDF. That’s why I suggested to drop them an email and ask. It’s also why I asked @pvdude what tape he used (although @pvdude may not remember). What was recommended by 3M for my aluminum tilting panel mount to TPO roof membrane was 1...

Jeez, it was right on the bottom of the RP62 page. https://multimedia.3m.com/mws/media/1015904O/3m-industrial-adhesives-and-tapes.pdf

What I did was contact 3M directly and asked. On my camper the question I asked was, “What tape does 3M recommend for attaching an ‘aluminum’ frame to a ’TPO’ roof on a camper?” I went on to more precisely explain my installation (lengths, widths, weights, wind speed, etc.). They replied within...

3M makes about a dozen VHB tapes using different adhesive compounds for different substrates. @pvdude, which VHB tape did you use?

Yeup! I never leave it alone. I disconnect and turn off before walking away.

It was just a tongue-in-cheek comment. I knew what a diode was. What I didn’t know was the circuit. In the old days it was said that the television’s 200 dollar CRT was there to protect the 59 cent fuse.

Thank you very much!! I have a pack of them on their way from AMZN. Six bucks vs sixty makes since to me!

Just out of curiosity, what will be the problem if that diode is not replaced? I once had the voltage incorrectly set on my PS and there was quite a spark, however, the power supply still worked so I finished my charging. Yesterday (a couple of months later after the “spark”) I was using the...

@smoothJoey , #8,,, my apologies,,,,

This is an interesting thread. So, I can turn the balancing off (Thanks to @Sharky722 - set balance start voltage to above the hvd) and use Active Balancing - OR - balance all the time via sinowealth and set BOC to zero. ? What rationale would one use to choose one over the other?
