    24 Volt Panels charging 12 volt battery MPPT

    That i good news! So I guess I can use 200w 24 volt panels in 2 pairs. Any advantage to using 2P2S vs 2S 2P?

    24 Volt Panels charging 12 volt battery MPPT

    I tried to find a thread on this but no luck. I have 2 BB 12 volt batteries in parallel in my RV. I want to put up to 800 watts solar on my roof and charge with the 40AmTracer BN or the 40 Amp Rich Solar. The pre wiring from the roof to the SSC is 10 AWG so max 35AMPs If I go 12 volt in...

    Hello All First Post Solar Design

    Finally finished this project, well the first phase, see photos. I have the inverter, transfer switch, monitor and wiring to roof and a frame done. I am driving this with a 200 Watt panel and PWM attached at the a frame and getting 60 amps a day of power (mostly sunny days). Really cool! Next...

    Hello All First Post Solar Design

    Thanks , it the 12 volt will not hurt the battery, sounds like it will not do much, I guess I could install a diode to block the backflow. Pulling fuse sounds way easier LOL

    Hello All First Post Solar Design

    I will tie the brakes and tongue jack in on the hot side of the disconnect so no worries. What I am struggling with is the 7 pin 12 volt power. If 7 pin 12 volt aux powers the break away controller and brake away controller gets power from LI Battery only when breakaway is engaged. Then the...

    Hello All First Post Solar Design

    I am planning to put a disconnect on the negative side of the battery. Which would typically go first the disconnect or the shunt?

    Hello All First Post Solar Design

    Ok so need another fuse after the buss, cool. No worries, Inverters come in so many flavors, with TS, solar CC, I should have been more specific. I did contact Giandel last week and they said the wires are pure copper and sized for their inverters. They are 35mm2 which as far as I can tell is 2...

    Hello All First Post Solar Design

    Ooops forgot the 50Amp CB on the MPPT to the Battery, Thanks. I like the serial panel idea, I could do that with the 2 on the roof, but the third is ground deployed so I would need some kind of switch when it was not in use. Maybe I can serial the 2 roof panels and plug the PWM for the ground...

    Hello All First Post Solar Design

    Hello, First Post I have been lurking on this board and watching Will's Vids for 6 months. I have a lot of electrical wiring experience, dad was an electrician. There is so much great knowledge here but solar it can be a little overwhelming. So I have studied as much as I could made some...
