    I had a similar problem in that my water pump would overload the inverter if it tried to start while the inverter was in standby mode. So I cobbled up a second pressure switch set to a slightly higher tripping point that when activated, turned on a night light bulb. Eventually replaced the substandard motor with a high efficiency Leeson 1/4 hp and never needed the second pressure switch and load.
    But now, with the price of solar so low, why not just leave the inverter running 24/7? That's what I'm doing now.
    Island cottage solar system with appriximately 2500 watts of panels, 1kw facing southeast 1.3kw facing southwest 170watt ancient Arco's facing due south. All panels in parallel for a 24 volt system. Trace DR1524 MSW inverter which has performed flawlessly since 1994. Outback Flexmax 80 MPPT charge controller four 467A-h AGM batteries. Insignia 11.5 cubic foot electric fridge 1/4hp GSW piston pump. My 31st year.
