    Combiner Ground

    So when I get around to grounding my solar panels it will be to an 8 foot driven ground rod Not to my household main ground! I have changed my thoughts on this, If lightning strikes the panels it will go to the ground rod. Lightning protection systems use ground rods and high points to...

    problem programing renogy 40A for my system

    What is the Nameplate watts of your fan? I agree with the others, your drawing too much power from your system. Basics.... what is the load and for how long? Your charge controller is it set up for LiFePO4 batteries or just plain Lithium.

    Question about Growatt AC IN

    If you look carefully at any late NEC it does not say UL, it says Listed and approved by the AHJ. If your install is Listed by some recognized testing lab and that is Approved by your local Authority Having Jurisdiction your covered.

    Battery + Inverter in a tiny popup RV vs mounting them in a milk crate

    I have 3 Renogy batteries. What is the issue, they each have there own BMS and a warranty? In case of a fire in or around your home made solar electric system.... the Insurance company is going to look at your self built battery system and say sorry.

    Mini Split on Solar

    Having worked commercial HVAC/R for over 30 years, I can tell you right now R410a has no business being in line sets with flare connections. The original mini splits had R22 and that was fine, but the much higher pressure R410a needs silver or Sil phos brazed connections. When I installed mine...

    32V charging from 3 100W 12V solar panels.

    The old, old farm Delco power plants were 32 volts. I wonder if changing it over to 36 volts would be an issue?

    Signature Solar wins... I lose.

    When I crated for shipping it was 2x4 or 2x2 Frame nailed to furring strips and the cheapest 1/4 inch plywood. Things strapped inside of course. Fork truck drivers did their best Not to put a hole in it!

    Noob question: 12V 100aH batts in series?

    The cost difference between a 12 volt semi conductor and a 24 volt one is pennies.... that is not the reason they were designed that way!! They are designed to be a 12 volt battery BMS only.

    Grounding panel frames on a RV

    If it was ground or roof mounted but these are on a RV on rubber tires. The reason you can not get a reading with your meter on the aluminum has nothing to do with a ground, the aluminum in the video has a protective coating your meter leads points did not penetrate.

    New NEC code makes it impossible for DIY systems to be compliant

    Does it really say UL approved? Most of the Code says Listed, they got in trouble years back by saying UL approval needed, now it has to be Listed and then or approved by the AHJ.

    Is Renogy Going Out Of Business?

    I have no issues with the Renogy app on the iPhone, if I do its not any different from the rest of the apps I use on the same iPhone 11 with all the upgrades. I am in the ending stages of setting up a off grid back up system with 600 watts of panels. Everything I have received from them has...
