I guess maybe perhaps you shouldn't watch his videos anymore if you don't really like them. BTW, he did go over several of these points, he did mention he reached out to Sol-Ark and spoke with them. Also in your screenshot where you say 'David Poz Please Read This', he actually posted that same...

In my opinion, an important part of the equation is to work a lot harder as a society to de-desertify more regions of the world. Like what John Di Liu, Allen Savory and others have lots of videos about. Those guys really understand that we simply need to get the Earth as a whole more green...

My previous stance: Potentially open-minded about getting a jab for a Covid-19 vaccine, if necessary to keep my job (which brand would be best to go with if I did do it?), me never really being one to ever get shots, never really saw flu shots as important, having faith in my immune system and...

Victron forgot to put in their manual, that every time you stop to park your RV, you should pull out your 6ft copper ground rod and sledge hammer, pound the rod in, and ground your solar gear for safety/lightning strike, and when you leave use your slide-hammer to pull it back out (or it can get...

As I am continuing to develop my homestead property out in the desert where there is no easy power or easy Internet, several of our other shareholders on our co-op use traditional satellite Internet solutions, in which they complain about their service quality constantly. They tell me video...

I managed to finish the 48v banks tonight. All went well, cells are all insulated from chassis now, got them all torqued down with a bit of pressure. I am chalking two 2x4's under each battery chassis running down the sides for extra support for the weight on the bottom plate. It holds the...

Well, a lot of these inverter types must run in 'inverter bypass' mode in order to charge the batteries, which means the generator is supplying the household AC loads in addition to powering the battery charging load. Many of them allow the user to turn down the amperage on the battery charging...

Here's a couple pictures of the LV6548, came in the other day, just had a chance to unbox and have first look:

I just helped a neighbor fix this F90 mayhem on a 6500EX the last two nights (learned several things along the journey)... Fun facts about F90 error... -You (the user) likely made some change exactly 60 days before the F90 triggered (1440 hours before), like firmware upgrade (yes, that was us...

I'd rather prefer to do it the other way around. Have a breaker on each battery pack (for each battery to disconnect independently, break it out of the battery array to service a single battery pack at a time), and then put the Class-T fuse(s) on the other side of the bus bars, one going to each...

I had purchased two LV6548 a few years ago, then later I got to thinking, as I started seeing China putting a lot more pressure on Taiwan's physical boundaries more than any other time in history, I'd better get a couple more spares (in case it soon gets very hard to acquire more), so a year...

If my wife got pissed about my last battery purchase, I would have just bought her a set of cubic zirconia earrings and taken her out to dinner at the local buffet restaurant, but luckily she got over it fairly quick, so I was able to put that money into my battery fund for next year's expansion...

About 20 years ago, I wired up a 1500 VA APC UPS for my stepfather to run his pellet stove to cover for power outages. I took out the factory batteries in it, and install longer battery wire extensions on it so I could connect it up to some larger size GEL batteries externally (two 12v batteries...

What city or rough area are you in (in case there is somebody close by you who could help in your area)... When looking at what seems to be like a big mammoth problem, always stop, don't panic, break the big problem down into a series of tiny problems and create a checklist. Don't be...

I second this on the importance of R value and sealing the envelope. I would study up somewhat on 'passive home' strategies, and determine how you can renovate in a way that can seal the envelope, improve R value significantly, make use of natural effects (South Sun), capturing sunlight in South...

I finally got around to putting together my 12v and 48v battery banks (holder/clamp assemblies)... Just thought to post some pictures of it as a couple people had asked me before here. Still have to mount the BMS's, install the heat pads on bottom plate, thermostats, wiring, etc... But it's...

I've set my 2 Victron charge controllers to 14.08v Absorption and 13.4v Float and doing the 10-year test now, so far it seems good. I'll report back in 8 years...

Also, if you're in immediate need of assistance, go find a Mormon church and find/talk to the Bishop. I am not an active Mormon for many years now, but I grew up Mormon and know they have an outgoing and compassionate humanitarian program which I like, and they can help people who need immediate...

My guess is the inverter was doing MPPT sweeps on the circuit, and due to weak setting Sun, the voltage was lazy, so the sweeps were fluctuating the voltage a lot, as it couldn't get anywhere near to finding Imp at that time. Try more testing when the Sun is strong, and the voltage should have...

Am I missing something here? Why not just use a BMS which has low-temp cutoff (in addition to the high-temp protection), as the last line of defense, and wire in the heater pad with digital thermostat like so many others here have done (with the posted how-to threads and whatnot)? ...So you can...

Some options? 1. Eliminate the Anderson connector in the battery bank (straight run, no connector). 2. Increase the size of the Anderson connector in the battery bank to match the size of the Anderson connector lug/holder you want to run. 3. Get a copper bus bar/block to attach the 4/0 cable...

Doesn't it seem like if the step is really necessary to precharge an inverter, the manufacturer would put that warning/step into their manual for that model? And then what happens when your BMS decides to turn off on safety protection? You have to add that ritual into your routine every time...

When I used to be a mechanic, we would use valve spring pressure testers to help us determine what a cylinder head's valve spring 'installed height' should be set to. They have cheaper ones where you can use a bench vise and put the tester on one end of the spring...

Looks awesome! Thanks for the pictures and providing all the information about your install... I am planning a similar type setup, using these parts: Mine isn't so custom (as I just purchased off-the-shelf parts along the lines of some others had done on this forum), but hoping it will get...

I do believe it would be a good idea to have the bolts in there if you live in an area which could be prone to earthquakes. In the datacenter labs I am in charge of at work, facilities management wants all our racks to be attached to the cement floor with concrete anchors, and all servers /...

I made more progress on the 48v banks today. They are both fully operational now. I'm glad I added those 2a active balancers since they come with bluetooth management app, where the two BMS (I bought originally), are unmanaged. It is nice to be able to log into the balancers and see each cell...

I just used these ones here and fold the wires either once (to get 2 thick), or twice (to get 4 thick), depending on how small the wires are (to get a tight fit), before crimping them in. You have to twist really tight, crease the wire with your fingernail, pinch very tight, make sure the...

If it were me, I would run it hard, then while it's hot and running hard, do a voltage drop test at various points, this is where you put the + lead of voltmeter on one end of a cable, and put the - of the voltmeter lead on the same cable, but at the other end of it, it could for example show...
