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?
