    What voltage/capacity is the battery and gauge of battery to inverter conductors, if not sized correctly the voltage will drop rapidly causing the inverter to shut down on low battery cut off. The array is obviously too small to support such a large load if used for any length of time, you need to calculate everything to build a system that will work, there not enough information at this point.
    1500W, 6× Schutten 250W Poly panels , Schneider MPPT 60 150 CC, Schneider SW 2524 inverter, 400Ah LFP 24V nominal battery with Battery Bodyguard BMS 
    Second system 1890W  3 × 300W No name brand poly, 3×330 Sunsolar Poly panels, Morningstar TS 60 PWM controller, no name 2000W inverter 400Ah LFP 24V nominal battery with Daly BMS, used for water pumping and day time air conditioning.

    Going to need a lot more power to run a 1.5hp pump   And a large, Pure Sine inverter. 
      look in the chart below for 1.5hp
     46A @ 230V for starting = 10,580 watts
     12A @ 230V running = 2,760 w
      Throw in 30% more for the Power Factor losses, 4Kw continuous load is what you are looking at.

    Change my mind.
