FiveStar Solar Inverter that left me in the dark

I purchased a 10Kv hybrid solar inverter from FiveStar. My installer installed the unit and the unit was faulty. Do not for one second think that this manufacture has any sort of warrantee or guarantee on any of their products. The unit was then in for repairs as they do not swap out brand new faulty equipment. after one month of being told the unit is ready and two visits to the shop the unit was still not repaired. upon enquiring again when the unit will be ready i was told the repairs will cost R8500 on a brand new unit that never worked. Stay away from the con artists !
