Thinkpower inverters

HI,
I am intended to give a review about ***“THINKPOWER KTL 15 INVERTER” with 5 years warranty .I have installed the unit about 18 months back in my country Pakistan (marketed by M/s NMC Energy Ltd).
Unfortunately ,by the last week of July I faced a problem of MPPT 2 shortage. I have contacted the company .There is no service centre of NMC in Pakistan .They are selling THINKPOWER with different trade marks like NMC & KNOX etc. The pretend that there will be a full replacement warranty of THINKPOWER will be available at site by them with backup of THINKPOWER.But there statements are false .
I think that the THINKPOWER is not a reliable inverter and it is wastage of money and time.

BEWARE OF These people .THINKPOWER IS A THIRD CLASS CHIOCE
