If the pump uses 92Watt and is AC them it s AMPs should be lower. If you have 110Volts, the A would be 92/110 = 0,84 A
Please check with the specs/manual of your pump.
You could research using 12V DC pump which would erase the need for inverter and the losses of it. It should be more economic to invest in 12V pump than into more batteries, more panels and inverter

With two tanks for clean water – one low and one high, the pump would use the solar power directly to move the water up, without any batteries.
How much flow do you need?
