Years ago when I investigated solar panels, I never imagined that supporting electronics would push the complexity and costs to be more than panels&inverter! I love DIY technology projects, but the stress level (costs, inspection headaches) takes all the fun out of it.I've now spent more on rapid shutdown than what I spent in 2019 on buying my 36x265W used panels and racking them with unistrut
yes but the last paragraph of the page says much. it says basically is you don't have a "bundle tag", you can may request a field inspection, where an inspector can tag it approved or if there are parts that can't be tested without a lab he makes a "call" n the viability. A windmill farm has no tag, he has to make the call. An RV has no tag he has to make the call. Not sure they will get same results. I suspect hiring an engineer to stamp it all will get it done unless it's political, but is the RV guy going to pay the design fees?Regulations and building codes protect people living in buildings. Construction contractors have every incentive to cut corners since the goal of capitalism is to maximize profit.
Yes, they still need to be compliant. They hydrogen risk of AGMs is exaggerated, but FLAs is very real. The other concern is you essentially have a hazardous chemical inside a residence, which can affect fire fighting.What of AGM and older technology batteries? They aren't nearly as likely to set themselves on fire as long as they are installed with overcurrent and overtemperature protection. It does not exempt them?
A UPS is still considered an ESS, especially if it is not portable. 480 and 706 are not mutually exclusive.A little more specifically - if I understand it correctly - is that a UPS system is specifically not a type of ESS (as far as NEC article 706 defines it), and so only has the battery requirements section (NEC article 480) applies.
It’s what I’m going to use.
I figured 480 applies to all systems using batteries, but the informal note made it seem like an UPS system should be considered differently? (but of course what AHJ interprets/wants)A UPS is still considered an ESS, especially if it is not portable. 480 and 706 are not mutually exclusive.
It's been a while, but I think that is in the International Fire Code. NFPA 855 also has a small reference on residential installations. (But that is a poorly-conceived standard in how it defines an individual ESS.)I’m having a hard time finding where lead acid doesn’t have the same requirements as any other chemistry in NEC.

They have already done that. I’ve read the average person commits three felons a day…Make everything illegal and everyone will be an outlaw.

I loves me some pdf from the typeset.
All I know is a trailer is not covered by the building code unless you connect it to your house as a source. Then NEC 2020 might apply when it is connected as a source of energy from batteries.If had a solar install in a trailer, what technically applies or is in the pipeline to apply?
Here’s how one can generally tell if somthing will soon be regulated by someone or somthing …..All I know is a trailer is not covered by the building code unless you connect it to your house as a source. Then NEC 2020 might apply when it is connected as a source of energy from batteries.
