well bhai i don deals in invertors or solar thing but heres the detail .
Infini is a True Hybrid inverter .... Axpert is just 2 different low end things joined together..... performance difference is way way way too much.. also, axpert cannot do half of what infini does.. for detailed comparisons, download both their spec sheets from company website and compare them.. you will understand ..... if you have buget, go for infini, if you dont axpert will be ok for small loads.. just buy a seperate charge controller with axpert, as that is the worst CC ever seen... even Infini CC is only 60% efficient.. but much better than axpert, which may dip as low as 30%...marketting of cheaper low end devices with big false figures is comon, as more people prefer buying cheap stuff to save money, and then cry later ..... axpert is a very low quality inverter, not because of just the inverter part.. it has very poor lowest quality IC, board, cheap transfomer, a very inefficnent inverter, and a highly power wasting CC embedded in it.. and none of its joined together compnents play fair with each other leading to too much power losses and extreme difficulty in upgrading the setup beyond a limited point.. also,. thats jst marketting hype about high torque appliances,, infini ca manage more heavy appliances than axpert and better.. infini 3kva is 3200W, while axpert 5kva can barely manage 3500W in real practice for longer times..
