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...
