    Resistance heaters typically do not have a large surge (there may be some, many elements can have lower resistance when cold). Placing a voltmeter right on the DC inputs to the AC inverter and see if…

    In my humble opinion, taking an older (say older than 1 year) FLA car battery "dead"--Even if you get it recharged and running, it can very easily die again in 1-14 days at any random time.…

    Yea... The are about the same "efficiency" for a properly designed MPPT and PWM systems. That is because the Vmp~35-38 volt array on a warm day is just about the "perfect voltage"…

  • Re: Voltage mismatch

    BB.BB.
    What type of batteries (sounds like 6 volt * 8 batteries = 48 volts nominal). For most Lead Acid chemistries, 62-64 volts is fairly aggressive charging (or equalization charge). I am guessing you are…
