I run two MultiPlus 3000 units in split phase in my RV. I run their output into a Victron Autotransformer (32A model) to provide load balancing between the units.

Not my manual. I posted the entirety of the warning above and it says nothing about reverse polarity.

Where do you see this reverse polarity information ?

I am considering doing this but I am hesitant because I read this on the spec sheet of my 75/10: Max. PV short circuit current 2): 13 A When you go to the bottom of the page to read Note 2), it says: 2) A PV array with a higher short circuit current may damage the controller. Is that...

I thought the same thing when my friend was going through the permitting process. After talking with the structural engineer, I had to agree the rules are there for valid reasons. In this case Florida is a hurricane target. It is also very common for severe thunderstorms to roll through almost...

Think energy audit - you desperately need to perform one before you spend a dime.

He did not hire an electrician. We installed and wired all of the components ourselves.

If the permit application requires a licensed contractor to be named that has been added since we installed his. We did all of his electrical work.

I have read every post in this thread. My sincere best wishes to the OP and his family. That is a horrible experience. If there is a donation web site someone please post a link - I will gladly contribute. I can't imagine the depth of the loss they are now going through. Amazing courage to post...

To be fair almost all melted / burnt fuse holders are caused from poor connections, not from faulty fuses. There's a huge difference.

This is one of the most disappointing aspects of life in America today. Unreal that a country with over 1/3 of a BILLION in population cannot offer up better candidates than the ones we see, year after year after year...

I don't know if this will help or hurt but here is an as-built diagram for the system I have installed in my RV. Note that there are only 3 panels installed on the RV - the other 3 panels are ground-deployed when needed:

I am not a fan of breakers on the battery side of the system. A properly sized fuse and a battery switch is a more reliable solution, IMHO. Victron sells 275 amp battery switches for about $35 - put one on each battery feed in place of the 58V 200 amp breaker in your diagram. If you need to take...

My buddy lives in Tampa. Two years ago I helped him install 36 panels, an 8K Sol-Ark, etc. He used this company to do all of the panel / roof / wind calculations. They provided a permitting package which had cut sheets, a CAD drawing, power calculations, etc. The "inspector" came out after we...

I'm happy to report that I contacted the vendor and they shipped a replacement panel to me via FedEx. Even though it came from Hong Kong it arrived in only 5 days. I'm pretty happy with that.

Your solar panels will wire into a MPPT controller. The MPPT output is typically wired into the battery bank via a bus bar. The Multiplus-II is typically wired into the battery bank via the same bus bar. Where are you putting the battery breaker?

There are just the two of us, although we do entertain guests at least once a month it seems. I have been looking into swapping one of the water heater elements to a DC unit and wiring in solar power to it.

I too am wondering why you feel you need to switch the neutral? Please share.

Thanks. Like I said, I'm a visual person so drawings really help me to plan and execute and troubleshoot. All of the subpanel circuits are indeed 120VAC. The wifey did ask about putting the water heater over there. Thoughts? I understand the break / make operation of the MTS. I just want...

If you are reading this - thank you !!! I'm looking for feedback on my system design / plan. I have thick skin - give it to me straight. :-) I am a visual person and I like to have clear documentation of anything I build - it helps me understand what is happening where and is a massive aid for...

Sorry to disagree but I don't know anyone who ever had a failure due to excessive head. Is there even such a thing? :-)

So I've run into snag # 1. It appears they set the wrong dimensions in their machinery when they punched the holes for the power connectors to mount to the box. I am going to contact them to see what they feel the solution to the problem will look like.

That video is more like a marketing video than an actual how-to video. I noticed in that video they say to put copper washers on the battery terminals and then the bus bars. My kits did not come with copper washers. The instructions say to put the bus bar directly onto the battery terminals.

Yes, the connectors are identical. However, in my instance, the long ribbon cable has a red wire amongst all of the white wires. The short ribbon cable does not. Maybe because they ran out of white wire I guess. :ROFLMAO:

Winner winner chicken dinner. I saw both cables in the bag and didn't bother to pull them out. You are correct - one is longer than the other. I really need to learn to be less literal when I read translated manuals. Thank you everyone !!!

I am reading the instructions and making an inventory of the parts and all seems well, except for this info on page 45. Do any of you have an idea of what they are trying to tell me with regards to connecting the wiring to the BMS? I don't see a "short wire" vs a "long wire".

1. You need to drive that ground rod down until only 6" is showing. 2. Multiple ground rods can cause ground loop issues. 3. Ground wires should be as straight as possible for the best protection from lightning. I'd get rid of all those wire loops at the ground rod. 4. The conduits from the...

Because paying it back would run counter to the real initiative, which has been in place for decades...

I understand that. I bought this house in 2010. I paid $245K and I refinanced some years later and locked in a 2.1% loan. My neighbors recently sold their house. Their realtor came over and asked me if I wanted to sell. He told me he could get me $650,000 for the house and he could get it in a...

Until we have a general population that is willing to answer these two questions truthfully, nothing is going to change. Are you better off today than you were in 2020? Is the USA better off today than it was in 2020? I can answer both honestly and easily with a resounding "NO !!!" My cost of...

What is going to charge that battery when the sun isn't shining ?

I don't know who you are referring to with your stupid commentary but I don't always forget anything. Shut up or put up. I have posted data - you keep saying nobody posts data and everyone builds strawman arguments. You are made of straw... Please show me all of the "big oil" people who...

Funny you mention the Salton sea. I read an article that had a paragraph on potential lithium extraction from the brine water there. "Direct lithium extraction offers an interesting domestic application in the Salton Sea, a highly saline and polluted body of water in California that currently...

Yep and it will not happen quickly enough, according to the doomsday predicters of climate change. Everything I see these doomsday people saying is we have until 2030 before it's all over. I'd be stunned if the US has replaced even 25% of ICE vehicles with EVs by 2030. I'd also be stunned if...
