Im running a 1500VA,24v battery inverter and Im using 2×12v 100AH batteries and 2×100watts solar panels.My problem is just after the batteries run out they charged but as soon as I switch on the load my inverter battery low alarm switches ON.What could be the problem?

Not enough voltage!

18V is the maximum voltage you can get from a solar panel designed to be a nominal 12V, so you would need at least 2 of these panels to charge a 24V battery. Don't forgeT to use a solar regulator to prevent overcharging and damaging the battery.
