wait a moment!! You mean you will start periodic inspections of the inside of SGP equipment? I see a big advantage with the wall mounted batteries in this moment. I think you could inspect them while in operation. Cannot imagine that with racks in a shelf.

yes, periodic inspections incl tightening wires, still need to get that torque wrench/ driver By the way it was "months earlier".. like in 30 months earlier. That user did regular inspections -- the last one had been 2 weeks prior to the fire. The bulging battery was replaced in 2021. I like...

yeah, that language barrier is an issue. What's happening is.. that they did NOT go boom as expected. The Victron fuse test starts at minute 9:50 and around minute 10:56 had been for 45 minutes at 176.5A and 90C warm (hot), yet not blown. At minute 11:30 he replaces the wire with a thinner...

the 2 videos are from a guy in Germany who tested Victron Mega fuses and iMAXXX Mega fuses. Those videos are not related to the guy who had the fire.

You bought the mega fuses? The other thread had a video where someone tested them. One user summarized it up: "After watching that video not sure anyone should be using mega fuses :unsure:" Post in thread 'House burned down' https://diysolarforum.com/threads/house-burned-down.83098/post-1090686

I have this one in my 24V system: https://www.amazon.com/gp/aw/d/B0BHSNYHHH?psc=1&ref=ppx_pop_mob_b_asin_title a no-name product, I fear. After reading on the risks, I may want to buy a known brand for the 48V system.

That was exactly my question for you LOL It's said probably on every of the 20+ pages in the house-burnt-down thread: fuses protect wires, not equipment. But yes, my intuitive answer is one class T per 48V battery. In the 24V system I have only 1 fuse, but those 3 batteries are not on a bus...

My 24V system has the class t fuse in a plexiglass container. It's supposed to contain a mess. I haven't had a chance to verify.

I think the worst case is one battery going bad and the others dumping into it. The thread "house burned down" is very detailed. The breakers may not be able to break the high current. Or they may be too slow. Wires melt in 0.1s at high enough current. I have a single class T on the + side of...

Good description why you like SA. The whole install looks good. SGP will like it. I have the entire main house (4000sqft, 2 kitchens, hot tub, electric water heater) on solar and used utility power for a few hours only (10 maybe) in the first half of March. If I charge the PHEV on the SGP...

I see they have another fan club on reddit. Good presence.

I have seen something remotely similar on an RV. Only when parked.

Prius Prime is also available with a solar roof . It's an option that costs $610. It gets about 5 m/kWh or better if you drive conservatively. https://www.motortrend.com/features/the-2023-toyota-prius-primes-battery-could-take-three-weeks-to-recharge/ From the article: "Those figures are...

Not helping Signature Solar to have this thread at the top. It probably impacts Google ranking etc.

Anyone looking to buy cheap breakers, fuses or switches should read this thread. 22 pages in 4 days. https://diysolarforum.com/threads/house-burned-down.83098/
