That arc was with a ~200 volt source, and will be a lot shorter with 60 volts or less, where the class T fuses generally come into play. I'm not meaning to foo-foo the added difficulty of safely breaking a DC circuit, it's just that all of the videos I've seen posted about breakers smoking and...

Mine get a pretty thick coating of blowing topsoil in the summer. The improvement in cleaning them is less than my capability to measure the difference.

Those big + and - busbars are stock JASSN. The design is to hook up to 3 inverters to the top bolts, and 6 batteries to the bottom bolts, via breakers on the + side..

Commenting on the JASSN, which I purchased. I was unable to convince myself that the JASSN breakers are non-polarized and ended up modifying the box to use Midnite Solar breakers that they say are non-polarized and also have a higher voltage rating. The box also has space for the current...

I did that in conjunction with a class T fuse in the 135AH Mason. I don't know what fuse comes with the 280AH Mason, but the MIDI fuse in the 135AH Mason is woefully inadequate IMO. The breaker is sized bigger than the fuse so it hopefully cannot ever trip, as I am not assuming that the...

Just saw this about 2 months later. Short answer: No new thoughts. The Masons have been working well. They won't get a real test unless we have a lengthy grid outage, but the overnight tests have looked good. Every time I have a wrench on one of the terminals I'm very happy that I added the...

You could be saying one particular product is marginal, or all of their products are marginal. I will state that the one Seplos product I have experience with is IMO not even close to being judged as marginal.

I bought 3 of the 135 amp Mason kits. Other than horrible communication with the shipping information, where I thought I was being scammed, it has been a good experience. I have a few gripes about the design which I was able to address while putting them together. Other than that, I think it...

The anderson sb175 connectors have screw holes, so they can be mounted to a chassis or bracket, just not panel mounted. You could mount to a bracket and have access via a cutout in the panel. If you haven't seen them in person, they're possibly larger than you'd assume. A few good pictures...

Just the 50' of awg 6 in the circuit will account for a loss of 0.5 volts at 25 amps. Throw in a some connections, bus bars, and a breaker and that could easily account for the other half volt drop. RVs are notorious for lousy wiring between the converter and battery. In mine I moved the...

Sigh, if your work wasn't done I would have asked why it's wrong to call split-phase power 2-phase, and yet call 6-phase power 6-phase. Maybe somebody else with a greater understanding than I can explain it. For starters here are some random Internet excuses to not call it 2 phase: - This is...

AIC is only 5,000 amps. I'm planning on using the panel mount midnite breakers with 10,000 AIC even though it adds a lot of work for my DIN-centric enclosure. I wouldn't be surprised if there are a lot of 100+ amp non polarized DIN rail breakers a year from now.

When there's a fault on the grid, a lot of non-inverter things can trip off, and I think it takes a lot longer than 6 minutes to get them back on line.

There are 2 things that have to fall into place: (1) Does whatever app that talks to the BMS run on linux?, and (2) Does you linux have native device support for whatever RS485 adapter you will use, or is there a driver that can be installed? I use mint on my laptops, but issues like this are...

Understatement! If you're the power company, it looks like single phase. If you're the consumer, it looks like 2-phase. I believe that it would have been called 2-phase had that name not had been already used for the 90 degree service mentioned in an earlier post. For those who want to dare...
