    <p>I have concerns as well, because I too have been considering the
      SolArk for upcoming larger designs.  I regularly expect the
      builders to test the system and expose any problems before the
      owners move in.  It should be able to run any properly operating
      120 v equipment there is.  Having said that, I once had a
      contractor's air compressor not run on one of my systems.  It was
      an archaic monster belt drive thing, and when I checked it, it had
      a missing starting cap, and a ground fault.  So no, the inverter
      should not have to operate faulty equipment either. <br>
    </p>
    <p>I have never had to use a balancing transformer before on any of
      my systems.  The Magnum 120/240 vac PAE inverters generally will
      run everything 120 I've ever thrown at them, have full 240 in/out,
      but they're rated at 1/3 the power of the Solark.  So something is
      definitely wrong; shutdowns are not acceptable.  I hope Solark
      addresses this immediately.<br>

                    have had this issue with a recent installation. 
                    It\u2019s a new off-grid house build, and so not many
                    loads to speak of yet, except mainly power tools. 
                    The Solark 12K will not start any of: portable air
                    compressor, table saw, and sometimes struggles with
                    a miter saw, which are each 16amps or less at 120V,
                    but I have measured close to 50amps start up for the
                    air compressor and table saw.  The air compressor
                    and table saw are 1.5HP each.  What helps is if the
                    motors are warmed up, or putting another load on the
                    other leg to balance the inverter\u2019s output.

                    <div>Was thinking we would install a couple of
                      dedicated 120V outlets for \u201chigh-current\u201d 120V
                      loads with a PSX-240, stepping down the inverter's
                      240 to 120.  My understanding is this will solve
                      the issue for starting these loads, but not sure
                      if we might run into issues with inbalance down
                      the road...  Would be curious to know if there\u2019s
                      another way to balance all of the house loads

                                  <div>Good morning Wrenches,<br>
                                    <br>
                                    I\u2019ve strongly been considering using
                                    the SolArk 12K unit for awhile but
                                    have heard from a few folks that
                                    there can be somewhat frequent
                                    issues with the inverter shutting
                                    down from line to line imbalance. As
                                    little as 1400 watts? I could see
                                    where these instances would be
                                    minimized with attention to detail
                                    on balancing all the loads but if\u2019s
                                    as little as a delta of 1400 watts
                                    that might occur with something as
                                    innocent as a toaster oven. Seems
                                    like it would also be less of an
                                    issue in a grid back up or AC
                                    coupled scenario but for off grid
                                    I\u2019d be bummed to be getting calls
                                    every couple weeks from an off grid
                                    client that trusted me to offer the
                                    right equipment.<br>
                                    <br>
                                    How much of an issue is this? Is it
                                    getting exaggerated? Those that have
                                    NOT had this happening was it on a
                                    full time off grid site?<br>
                                    <br>
                                    Has it happened less on sites using
                                    the "Limited to Home\u201d mode? I have
                                    an upcoming project that was going
                                    to be setup with a couple Radians in
                                    HBX mode and my thought was perhaps
                                    it might be an ideal solution there
                                    but if the continuity of electrical
                                    service was going to be provided
                                    mainly through batteries and
                                    inverting and not through the pass
                                    through relays the majority of the
                                    time then the site might likely
                                    experience this issue with imbalance
                                    shutdowns.<br>
                                    <br>
                                    There are many attractive features
                                    of the SolArk and I really like the
                                    thought of taking advantage of the
                                    185 amp DC charger versus the
                                    Radian\u2019s 115 but I\u2019m kind of
                                    thinking the risks may outweigh the
                                    benefits if these shutdowns occur
                                    even once every couple of months.
                                    Any of you have a long enough
                                    history with them to chime in with
                                    your observations? Are they most
                                    reliable for AC coupled with backup
                                    rather than off grid or the \u201cLimited
                                    to Home\u201d mode?<br>
                                    <br>
