I have this one and am wondering if it can handle LiFePo batteries and the issues that go with them?

    I also have 2 Panasonic H.I.T. 330 watt panels, and thinking of adding a 3rd one, for 990 watt total?

    My system is setup with an 2000 watt "Samalex" 24 Volt Inverter running off 4 USP 12 VOLT BATTERIES (80 AMP.) wired series/paralell, at present....
    Pretty "Goofy" eh ?

    I think firstly, I probably need to get a good 12 Volt (2000 watt) Inverter, and run batteries just paralell so my Amps would be about 320, instead of about 160 amps as now?

    You should get yourself a good 48 volt inverter and run your batteries in series. Batteries shouldn't be ran in parallel. Regardless how you wire your batteries you still have the same WATT hours. Difference is you are inverting the voltage at a much lower current, requiring much smaller cabling and current protection.

    Another benefit to running at 48 volts is you can quadruple the size of your array @48 volts vs. 12 volts.

    Running batteries is better in series. I was going to say in general, but I can't think of any time it's not better for battery usage and charging. Running in parallel requires more connections, often you would want extra breakers. In addition it's pretty much impossible to get each string of batteries to share the load and the charging equally.

    In addition, charge controllers are rated by the amperage they regulate, so a Morning star that can handle @1000 watt array at 12 volts, can handle about a 2000 watt array at 24 volts.

    BTW - The morning star is a good choice for a camper, it has a fanless design so it'll be quiet.

    Your statement above appears to show a lack of understanding about how these systems work. In parallel, batteries amperage is added and the voltage remains the same, for the same number of batteries in either layout, the watt hours of storage, remain the same.

    Watts=amps x volts, If you run an 120 watt load on a 12 volt system, it draws the same wattage as in a 24 volt system. 

    In a 12 volt system it draws 10 amps at 12 volts in a 24 volt system it draws 5 amps at 24 volts.

    I believe the Morningstar can handle lithium battery parameters, but I'm not sure. Are your batteries failing?

    You can set high voltage disconnect, max charge amps, and how much Temperature Compensation Voltage the batteries see.
      (settings done with serial cable and software called MSView from Morningstar )
    What it can't do, is stop charging upon command from the BMS,
    it can't stop charging when battery is below +3 degrees C
      That would have to be done with a SSR on the PV cable, commanded by the battery bank BMS
