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...

Works differently for me. I'm net zero on an annual basis or darned close to it. I get a free AC battery that can fully power my 400 amp service, with almost everybody else paying for it.

No bus bar attached to the battery. AWG 1 cable to the anderson connector, then the mating anderson is wired to the bus bar.

Part of what the CPUC said, translated: Well, it turns out that the old program that we though was right, is actually wrong, but what we're mandating now is the right way, trust us. “Net energy metering is effectively funded by ratepayers that do not have solar, and the tab makes up about 10%...

I'm planning on using the rolling wire shelves for my LiFEPO4 server rack batteries, and anderson SB 175 connectors to connect them. The shelves and casters are rated a bit over 2x the max weight I'll put on them.

According to a Honda patent that I read, their inverter generators have a very narrow range for the AC frequency and its stability. I doubt that their inverter generators would be able to parallel with any small non-inverter generator.

I vote that it's perfectly clear: Whatever you put into the holder (wires+fuses) must not produce more than 6 watts of heat at any given time. More than that risks a failure, the plastic case melting as an example.

Mine are inside, in metal conduit (in USA). Could be a local code thing.

Hardly any of them use a sync cable. Honda, Yamaha, and Harbor Freight are among those that don't. The second generator to start up senses the phase of the first on it's AC output and syncs with it. Sometime in the past I know Champion and Kipor used sync cables but it looks like the current...

These are attributes of the charger, not the generator. Not a Honda question. As far as I know, chargers with PF correction are still fairly rare. Xantrex makes some chargers and inverter/chargers with PF correction, saying the "typical" PF is 0.98. In approximate numbers, using this instead...

When sizing a charger, you also have to take its power factor into consideration. While the generator is advertised in watts, it is actually rated in VA. If you can find a power factor corrected charger, that's great. If it's not power factor corrected, chances are that you won't find the...

The DC output of the eu2200i is unfiltered and unregulated. It's simply a generator winding run through a full-wave bridge rectifier to the connector on the panel. Its output is pulsating DC that is suitable for charging flooded lead acid batteries and possibly nothing else. AGM batteries are...

Is it an eu2000i, or some other model? On the chance the growatt doesn't like the 126 volts, try adding a load like a space heater to pull the voltage down to see what happens.

There are a lot of the DIN rail breakers that have both an AC and DC spec, with only the AC spec printed on the breaker case. You have to find the spec sheet for the breaker in question for the answer. I couldn't find a spec sheet for the CHNT CB-125A on line, so that makes it kind of difficult.

And I found a Mersen data sheet that gives the DC breaking capacity of 40 kA at 240 volts. Either way, on paper this is superior to class T. https://ep-us.mersen.com/sites/mersen_us/files/brochure_BS88_Low-Voltage-Fuses-and-Fuse-Holders.pdf On the Bussman spec, it's showing the 100 amp fuse...

Can somebody decode the BS 88 spec sheet? Translate it from British specs to more common terms like AIC? One of the specs says "IR: — 200kA RMS Sym." which I'd guess might be the equivalent of AIC, but 200kA? That couldn't be right for a DC spec, and I couldn't find anything that looks like...

There is a QR sticker on the top of each cell. They are visible in one of the photos in post #2. They are covered by the balance lead PCB, shown in the next picture. I'd have to do a lot of disassembly to see one of the stickers. In hindsight I wish I had taken a good picture of one of the...

I do not know. There were no markings that mean anything to me.

I had a few dead 12 volt AGMs, standard auto battery size more or less, and the best I could find was Autozone giving a $10 gift certificate credit for turning them in. I found big-city recycling places that might have done better but wasn't interested in the 200 mile drive. The autozone...

The Outback ground fault detection method is to bond the DC side of the system (battery, PV array negative lead, charge controller, inverter) to earth ground through a 0.5 amp breaker., so if more than 0.5 amps flows between the PV system ground and earth ground, the breaker trips. When the...

I couldn't find in the video what the voltage creating the arc in the breaker is. Was it there and I missed it? I suspect that's just as big a factor as the current.
