3kVA 240V inverter and three gel batteries 100Ah 12V. And I am only running my borehole system 1st pump .38kW, 2nd pump .75kW.

The inverter lasts for five mins then goes off because of low battery.

    What cabling do you have? How is things connected? Three 12V batteries doesn't make 24V.

    Also post the age of the batteries, and if older, approximately how many times they were recharged and what device they powered before. And post the voltage of the pumps. Model number of the inverter would be helpful too, Nov 18 at 12:23
