well I am using Axpert since one year i have no issues yet from it. For testing purpose, i have connected my 2140 watt panels to it and it is really very nice so far.
So if a cheaper stuff can work good why to spend 3times more for almost same purpose.
Axpert is 5kW so cannot be treated as low sized inverter. I have used my 5kW to around 3kW including microwave oven and water pump and washing machine together.
i agree infini do have some edges over Axpert.
From farhan bhai's old posts, he is of the view that the pwm and mppt not to far in pakistan conditions. Infini has MPPT and Axpert has PWM...
by the way Axpert also have MPPT models..
so you have to make a decision where you spend as much as you afford and get optimum returns.
I am of view that for small sized installations there is no significant performance difference , because panel array is small and already needs to be cost effective cz of lower bugets most people have..
when mppt will fall in price over some years then pwm will be obsolete, Why? because some new tech will make mppt old news by then.. and same debate will still exist.
90% of axpert models are with a pwm cc.. and a very poor quality at that...tufail has a seperate mppt CC for charging if i remember correctly. so all the load is easily dissipated.
Tufails axpert unit @ 5kva is already over powered for his uses so the inefficiency of the axpert brand is masked in under utilization.. the problem is limiting yourself to 60% capacity by paying 100% for it... goodwe and outback have much higher tolerance and superior efficiency than any other when price is no object...with medium buget infini has much better quality internal components..
when price is object , be prepared to compromise on either performance or features.
