Yes the coling system is there,,,,,,it doesnt heat up at all,,,,,,,,,,No huge transformers,,,,its really compact and has a balanced weight
about performance,,,,,,it gave me 3 fans and 3 lights for 7 hrs with 200 AH battery
the best thing is that almost no wiring is required in this UPS ,,,,,just open ur ckt breaker box,,,,,,put the phase of ur house in the phase IN of the UPS ,,,,,take out the Phase out from the UPS into the ckt breaker and there u go,,,,,,it takes 10-15 min to start working ,,,,contrary to what i thought earlier,,,,,,,,,,,,,,,,,
they have no outlet in ISB/RWP,,,,,,but u can ask any of ur relatives in karachi to TCS it to u,,,,,,takes only 1000 Rs,,,,,,,
