After the fact

Used the above company to install a solar system. 2 years later we had issues and contacted them. The installer immediately assumed a fault with the invertor and we trusted him so went with it. The distributor, Solar Solved, just shrugged their shoulders even though the unit was bought from them with a warranty. Much ado later we had the unit tested by various persons only to have it returned with no faults. It turns out that the wiring from the installer was faulty and in the resolution of this he became very angry and started swearing at us. He also admitted that the unit was not new, as we had believed, but was in fact secondhand. No integrity at all and won't take responsibility for his short comings.
