If the shunt, or fuse holder is made out of flammable material like plastic it can catch fire if it has a hot spot. I suppose that could even happen with a hot spot on a battery terminal. When you have low voltage and high currents hot spots are a problem. Lifepo4 has flammable liquids once it...

My brother when he was a teenager used a lighter at night to check the battery fluid level on a car battery hydrogen sulfide gas exploded in his face. His face got a bad sun burn his hair was burnt some he was lucky the gas was probably not enough to do more damage. Not sure how his eyes didn't...

This is why my batteries will be enclosed in steel with 1/4" plate steel on top. Haven't had time to weld it together yet been busy with other projects soon it will be built. The box will weigh 250lbs itself I have casters already roll it around my garage. The only thing that keep this from...

You will want solar panel disconnects don't use circuit breakers. If you disconnect under heavy load DC arc will not break and melt the thing. Lot of YT videos on that subject. Make sure you buy a quality shunt there is a thread in up in smoke guy burned up his DIY battery bank from a shunt that...

Depends on the risk you want to take if your battery bank is inside a shed outside take little more risk on a cheaper fuse. If it's inside your home, or in an expensive RV last thing you want is to a fire because you wanted to save $40. I try to go with everything that is UL listed then I know...

Your adding a battery to your current grid tied system you be required to sign a new interconnect agreement, and lose the grandfathering. Also be required to add 2 more meters that is if you plan on permitting it. I'm just taking a few circuits going off-grid for battery backup I don't plan on...

Wonder about 110V inductive loads like window AC units would do this?

Did they connect to a different location because of the easement issues? Usually they can force a land owner to give easement if they don't agree to it by emanate domain. Even private power utilities can do this because of laws allow them to they have to go to court. It's a long process most...

He has an air gapped manual switch on the grid connection to the inverter it was shut off when they said it was back feeding. The only thing could have done it was through the neutral, or inductance between wires that were close together. I have wondered about this is have an inverter sharing a...

SRP Taking away from their profits which they claim they not suppose to be making any profit.

The problem is the only way you know is when you get a call from the utility I'm assuming rather not get calls from them. Maybe it happens lot more then we know lot of people have portable battery stations any of those could back feed somehow.

I went back and read that I edited my original post about the manual switch you have. I think the hybrids just a power circuit between the input and output. Possible induction how it happened. UL listed reliance control generator transfer switch going could induce voltage on the line side all...

xantrex xw6048 isn't that a hybrid inverter? Likely the power just coming from that. You should be able to see the inverter voltage spike up with an oscilloscope, or maybe a DVM that records max voltage. Watch what is causing the voltage to go higher then the grid voltage. You said the grid...

I'm no inverter expert but speculating the way these are designed hybrid VS Off-grid the hybrid always going have a parallel path with some kind of power circuit between the input side, and output side. Where the off grid has air gapped relays that direct power to the battery charger, or bypass...

That's exactly what I'm going to do off grid through a transfer switch with 6000xp I have one already working on installing. The only issue is cooling it because it gets so hot here in the summer my garage hits 95F in July and Aug have to see how hot it gets probably have to cut back the power...

I don't plan on mounting panels on my roof wife doesn't like the look of solar on the roof also if you ever want to remove it going to leave big mess on the shingles with black marks all over the roof from the sealant. That means entire roof has to be re-shingled I got it done in 2012 for 4500 I...

SRP like APS requires all the equipment to be on the CEC list (California approved). The good thing is EG4 18 and Powerpro battery just got approved on the CEC list. You have to get a new design plan go to greenlancer get plans drawn up. I would probalby ditch the current GT inverters and get...

Code is ECLIPSE5 Link

Leasing solar is a bad idea stuck with that company forever just one downside. Sounds like your DIY fix resolved it IMO I would just treat it as your own system and support it yourself who would know any different. My utility has been increasing solar connect fees, and reducing the rate they...

I'm simply stating that you benefitted by Government subsidizing and giving tax breaks to the solar industry. The reason Government has done that is because of Climate change even if you don't believe in it. Did you file on your tax's 30% credit for your solar system?

You realize that if it wasn't for climate change solar panels would cost $20 a watt probably not even exist like it does today. Industry not going to invest millions of R&D into an something that has no future. Government jump started the industry by subsidizing it and EV cars because of climate...

Video of flexible panels melted the RV roof.

What's wrong with turkey legs and Christmas. Have to admit Trump would have been much better off if he never got involved in politics. He probably have a new TV show by now. He might not say it publicly I do believe he wished never got involved in it.

15 feet of 10/3 is $100 at HD that is crazy pricing. Going to buy 250 feet of 12/2 for $100 shorter pay over $2.50 a foot. I found a 250 foot roll of 14/2 in the attic I must have bought years ago probably paid $29 for it. I haven't had issues with rats we do have roof rats here seen them...

House was built in 1976 bicentennial year. I remember celebrating Bicentennial in school was 8 years old when my house was built. Builders trying to penny pinch as usual. The house is slump block home with 2 flat roofs and a pitched roof in the middle. Almost every home built here in the 70's...

I watch local news once in awhile talk about local stuff which what affects me. Politics doesn't interest me just gets people angry rather talk about technology lot more interesting. Time to unwatch this thread.

Like to demo entire switch Jbox and remove all wire going to it pull a new copper wire up from outlet feeding that switch Jbox. That means more drywall work I suppose if I got better at doing drywalll I could just replace all the Aluminum wire.

Did you use purple wire nuts only ones rated for pigtail those are expensive. Contractor offered to come in and use a crimping tool he wanted $50 an outlet. I have pigtailed a few outlets where I put in a GFCI outlet others I replaced the outlet with AL rated one never found a lose wire. I think...

SEER is taken over entire season of use where EER is measured at 95F. I guess I'm only concerned with heat when we hit 119F every summer these units run full blast probably pull the same power as ones built 30 years ago. The rooftop unit I have now which was a 2021 model pulls the same power as...

I liked it better when news talked about tax and spending, ground hog day, Pardoning a turkey, Christmas Tree boring stuff.

Isn't EER more accurate measurement then SEER? I have always heard seer is measured when it's 80F outside when you get over 115F pulling power of an AC unit made 30 years ago. Mini split need R410 refrigerant have to add that cost in.

It will be the start of the end both will be fading off into history. I think once it's over lot less discussion about who is president.

I ended up ordering a 6000 XP I will just use it on circuits that match the amount of solar, and battery I have.

Can't wait till the election is over sick of hearing about Trump and Biden.
