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.

Mr. River Wang, CEO

They do keep track of consumption or export at least on hourly level. On their website, I can go back in time and see consumption/ export for any date / time in 1hr intervals .. not sure how many years back. Afaik, I have an old NEM contract. System is from 2004. They have all the data, but...

The system has its shortcomings, but there were only 2 days where their server was down. The first time they didn't announce it. I just couldn't log in. The second time they had an error message, IIRC, on the login screen. Unfortunately each time the outage was over 6h. Given that happened over...

It tells me the SOC and that most likely the house has not burnt down yet at time of viewing. I can also deduct from the load whether someone is showering or doing laundry or both. I like that.

Can we get the full story?

Off topic: Just to give you an idea how messed up our PoCo PG&E is. One of my renters called me 2018 that her fridge doesn't work. It was dark. I hoped to just give her a new bulb and feared to be on the hook for a fridge. Upon my visit, it turned out that her house had no power. I called PoCo...

Yeah, exporting to the grid without permission seems crazy. I previously had read your comment thinking it's a response to my posting about an off grid installation which would bring down the grid bill. I still wonder if a 20%+ drop in consumption triggers the aforementioned PoCo to do an...

Ummm ... which question is this a response to?

I do have a permitted grid tie 5kW system, 20 years old, and I added recently an off grid system. My bill month compared to previous year's same month definitively drops a lot more than 50%. As in from 1900kWh to 600kWh in March year over year. But there have been similar drops in past years...

In what geographic area is this the case?

No, I cannot remember that. I did not know it. And that's very critical information to be aware of!!! Appreciate it.

I was trying to find out about STC rating vs NMOT rating, to determine my panel setup. To see Isc and Voc. And found this post. For my panels, Voc is 40.6 (NMOT) vs 43.1 (STC). I suppose to determine how many panels can go on a string, I need to use the higher number, even if in the real world...

Just yesterday I read in another thread here about someone who had exported less than 100W for less than 15 minutes and he received a phone call.

I had no idea!

Can you explain this? My grid delivers 245 to 248V. What would happen if it were 270V? My appliances fry???

50% were reached a little while ago and no more power consumption from grid. As it should. 👌

I didn't think that (although all cloud solutions are a potential target for hackers). But with an internet outage, I believe *some* ring installations will fail to make the chime work. I had bought a ring system for a spec house that I built (for sale) and was told that the door bell won't work...

Yeah, the one that came with the unit. It sends my data every 5 minutes to Cindy's servers. Tbh, they are not SGP servers. It's a separate company. I normally am against unnecessary cloud solutions. I laugh about the people who have a ring door bell that goes through the cloud for everyone...

I still use this one, gives Cindy in CN something to look at. If my postings are not to her liking, she can shut me off.

I stopped paying attention since the APL mode issue was resolved.. by this forum. I check 1x or 2x a week how warm it is getting in the shed, and am thinking of replacing the duct fan with a more powerful one. It's below 97F so far. What I started obsessing about is the PG&E (power company)...
