    Nice Rack

    Sorry about the title. I couldn't resist. Member @D. Abineri sent me a PM the other day asking about my angle iron solar panel rack and I said I would send some pics. I figured I'd put it here in case it is of interest to anyone else. I built and assembled the rack. I made all the brackets and...

    Ham Radio and Inverters

    My Magnum inverters do pretty well. Mine are within the loop of my main antenna and there is no prblem. My Midnite Classic 150 makes some hash on 80 meters but since I only do 80M at night it isn't a problem.

    Needing to know how many batteries and solar panels are needed.

    One thing you don't mention is a generator. A 5kW or so would be fine for thins setup. I personally don't have three days worth of battery power and never have in over 20 years off grid. I just charge every day, sun or generator. If my power slurping hog self isn't there the system would go...

    Needing to know how many batteries and solar panels are needed.

    Make sure to use the term watt HOURS. It does seem that you are calculating watt hours but using the term watts. Very different meaning. It sounds like you realize this too but in terms of batteries what you need to know is the after dark loads. Running a fridge is no big deal, I run two fridges...

    Solar array, 3S2P vs 6S

    +1 with what @Snowboater said. I'd just add don't forget you are working with high voltage. Make sure everything you use is properly rated and watch out for shocks.

    Solar pv voltage too high

    Yeah, switch to a 2S4P configuration. UNder cold and sunny conditions your voltage will go up. Something will pop one of these days if you don't.

    Charge management

    No. An isolator allows the alternator to be connected to the house battery to charge yet prevents the start battery from being run down by house loads.

    Charge management

    The alternator has it's own charge controller of sorts. Most are pretty crude. There are some out there with real smart profile. Solar has its own charge controller. Wind generally has to have a load or be able to furl and you'll have to see what its requirements are but it needs a charge...

    Shore power and solar

    They solar charge controller and shore power should play fine together. Your solar will mostly be idling if you are plugged into shore power as your batteries will be fully charged.

    Ok to mix panels?

    It will work. Depending on the specs of the panels you may not get full expected output. Here is an explanation of what to expect:

    Are my battery cells defective?

    And if you aren't yet equipped to top balance you can connect them in parallel for a day and then connect them in series and charge them. Then you can pull some power out of them and see how they do. However, you do want to top balance eventually before putting the battery pack in service.

    Currently using Crown batteries. Last bank was Sam's club. I check the water levels once a month and usually add some every 3 months or so. Taking 200aH out of a 300aH bank will wear it out quickly.

    Wire size and breaker size protection

    At 12 volts, 1500 watts will pull 125 amps. So of course you can't use the maximum rated output of your inverter. A 150 amp breaker will protect the wiring but will leave the BMS as the primary circuit protection. As to what gauge wire that depends on the length of run. You can use this...

    DC-DC Chargers in Parallel

    I put my input breaker on the base of the driver's seat, Makes it easy to reach down and shut it off and turn it on. However, my battery is under the seat so it made that easy.

    NEWS: New Midnite Solar DIY Series - SCC's & Inverters (great $ too)

    Awesome! A friend and I were commenting recently about how Midnite was getting left behind and entering "OK Boomer" territory. Really glad to see they are staying in the game. Although I don't know why they can't put a software patch out for the Classic to handle LFP.
