Re: OpticsRE says I have a magic free energy machine...

The FNDC has room for three shunts. Why are you ganging them on one side or the other? Just add another shunt and measure whats coming in from the panels/FM, another going out to the inverter or yet another going out/in elsewhere? It's a cool device. What am I missing? What you can't easily get is i...

Re: How does the FNDC determine which sources are connected to it’s terminals?

My FNDC has been disconnected for most of this year. Why? The wife is over reliant on the SOC from the Mate3. When the battery problems got bad the SOC calculation was totally unreliable. It didn't matter what I did, as in to fully charge the batteries per specific gravity max and reset the FNDC. Wi...

OK, I understand. We raise pigs and sometimes on occasion, they become dog food. The dogs really like them lightly smoked and seasoned.

Hmm. a dog tucker. I like that.

Re: Installer won't deregister our MAC address

What is the age of majority on a solar setup? How is support determined - by panel? Is the Daddy the installer? What if more panels were added at a later date? What if from a different installer? What if there is not the equivalent for a birth certificate (install receipt/home birth) of the panels/c...

Re: 1 of 8 RE16-B

Hi JR, I had a “1 of 8” L-16 REB issue with one cell going out after 6 years use. I replaced the one dead battery with 2 Trojan golf carts (in 2018). The overall battery bank has now had almost 8 years of use, so I have gone ahead and proactively ordered another 8 REB’s. They have been good to us. ...

For some inscrutable reason the installers have them pointing about 40° off true south. I’m trying to contact them to find out if there’s any reason I am not aware of for having your panels so far off optimum.
Its really difficult to do this stuff after the installation.

If I were to try swapping out that 20A CB for a 25A CB what is involved with that? Ie, do I need a special type of breaker? Any gotchas?

Re: Few-x240 Autotransformer 20A circuit tripping

Somewhere in the forum is a post about the X-240. If I recall correctly it said that (paraphrased) if you are reducing 240 to 120v the transformer will pull slightly more current on one leg of the 240 than the other. From my understanding its just the physics of the transformer process and how its w...

Re: 1 of 8 RE16-B

it is not unusual to have daytime temps hit mid 90s and into triple digits just have them drop into the mid 60s through the night. Your temps are very similar to what we have at 5,500' in AZ. We may break 100 one or two days a year in June (not this year) but nights are typically in the 60s. I fina...

Re: 1 of 8 RE16-B

What is curious are the battery temps. The battery temp has been climbing up steadily for the last few weeks. Now at 96 +/-. And this has to be one of the coolest summers in memory. So here is the question: for a FLA battery bank that is under-performing, why are the temps climbing? Power = i²R. Ei...
