    Installed New 1300W Solar, 400 Amp Lithium Batteries, 3000 Watt Inverter and Surge protection: Critique welcome

    Hi All,
    I spent it seemed like forever on line researching what alternatives were available for a solar/battery/inverter and protection setup and I never ran across anything that seemed very professional or that seemed like a complete top to bottom system.

    4270 Heartland Cyclone
    1300 Watt Solar & 400Amp Lithium

    Here is what I installed starting from after the transfer switch, let me know if you have any questions.

    1. Surge Guard 35550 Permanent RV Surge Protector 50 Amp. With Remote Monitor
    I would carry a spare as I've heard these will blow and are not re-settable. Or just use one that plugs into shore power before your AC cable
    2.
    Go Power GP-IC-3000-12, 3000 WATT INVERTER / 125 AMP CHARGER - 50A TRANSFER SWITCH with Remote Monitor
    This is the only unit that I could find that will pass thru both 50amp legs of 120v while your hooked up to shore power.
    So basically this unit can be in-line from shore power to rv breaker panel vs the other nonsense of sub panels.
    3.
    BEP Marinco Power Products Pro Installer EZ-Mount On/Off Battery Switch 400Amp
    4. Go Power! FBL-400 Class T 400 Amp Fuse with Block
    5.
    Copper Grounding Busbar, Ground Wire Included: No Item # 22LU64 Mfr. Model # HBBB14210A 2ea.
    6. Battle Born LiFePO4 Deep Cycle Battery - 100Ah 12v with Built-in BMS - 3000-5000 Deep Cycle Rechargeable Battery
    7. Outback Flexmax 80 FM80 MPPT 80 AMP Solar Charge Controller
    8.
    Blue Sea Systems C-Series Single Pole Rocker Circuit Breakers 30A & 80A
    9. SM Panel A Series CB Breaker enclosure
    10. LG, LG330N1C-A5, PV MODULES, 330W, BLACK FRAME, MC4-TYPE 4ea. If you want to double this you can go to 24V wiring

    Re: Installed New 1300W Solar, 400 Amp Lithium Batteries, 3000 Watt Converter and Surge protection: Critique welcom

    Hi Ron,

    Nice looking setup. I have a somewhat similar system with 6 golf cart batteries and I haven't mounted the panels on the roof yet. Mine also doesn't have the voltage regulator thing like yours has. I'm using a 2,800 watt Magnum inverter and a Midnite solar classic 150 charge controller.

    As to your panels you may get some loss from shadows from things like vents. That's one thing that I have noticed that some people use smaller panels and more of them to get them away from anything that will create shadows. Have you been using it since you got it all hooked up? And will the inverter run the A/C system?

    Looking forward to hearing some updates on it.

    Big B

    If you haven't already done so, you need to change the setting to "custom" on you IC3000, so it charges correctly for the Lithium. I have this documented and can send you the info you'd like. PM me your email address and I'll send it over.

    Once I did this on my system, my 6 BB's were loving life!

    Magnum/Midnight is the other option I liked, but have Outback at my house. Both treat the solar as off grid. I have run the ac off the system, but it really wasn't designed for that and im pretty sure that if the wfey turned on the hair dryer or coffee it might blow .
    System is performing extremely well and haven't had any issues other than when plugging into bad campground power. Glad I installed the inside surge protector. It tests the power before engaging. Generator runs through system well and haven't needed it yet. I didn't use 12v panels because I would have needed like 12 of them which would not fit.

    I forgot to ask you about mounting your panels on the roof. The guy that I bought my panels from (280 watts) told me to use double stick tape under the z brackets then self leveling caulk over the screws. How did you mount yours?

    I know 3M VHB tape is used on motorhomes with fiberglass roofs but I've never heard of it being used for EPDM/TPO roofs. Not sure it would be effective. That you are using screws as well, should be good to go.

    On mine, I used butyl tape under the brackets as a sealant, then SS lag bolted the brackets down and added Dicor Lap Sealant around the bracket and over the lag head.

    Thanks for the info Jim. I decided to use unistrut to mount my panels on. I'm wondering if I should try to hit the rafters or just put the 1/4" stainless lag bolts into the plywood roof without regard to where the rafters are. I can't remember for sure but it seems like the Bighorn has steel rafters.

    I think the trusses are aluminum. But for sure not wood.

    I'm pretty sure that you are right on that. If I recall correctly there are metal rafters with 1/2" plywood on top of that. Did you try to hit the rafters with your mounting screws or just go for the plywood alone?

    I just went for the wood. Trying to find and hit the center of the trusses would have influenced where I could mount 6 long panels on my small roof and I felt these lightweight panels would be good to go with 4 lags into the plywood. Two travel seasons and maybe 20,000+ miles says - we're good
