Huge Investment - down the drain

Please be warned do not use them. After sales services shocking and did not install inverters as laid out by SANS which resulted in the inverter failing (blowing up).

The root cause of the failure, according to an Independent Assessor was the result of incorrect installation practices and not having followed the requirements laid out in SANS. Any competent person would have ensured the correct installation practices were followed and comp**** to. Very limited knowledge of the requirements laid out in the legislation and wasn't qualified to do such work. A very expensive lesson for us that we should have used a qualified and registered person who was 100% compliant.
