E-egineering SMS Solar

I bought the solar system , from E-engeneering in 2017. Was installed in march 2017. In September 2017 he 8 Energiser deep cycle batteries were replaced with 4 200Ahr Narada's. The installation was totally unsafe, a fire hazard and not compliant. the Mecer invertor was not grounded, an AC breaker was installed between the solar panel and the invertor. This is totally unacceptable and a fire hazard. (Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules).The invertor had an earth wire to a ground bar but this was not connected to anything, a 220V AC device with no earth connection. The solar panels were not earthed. not required said the electrician who did the installation. No DC fuse installed between the batteries and the invertor although the installation manual says"For safety operation and regulation compliance, it’s requested to install a separate DC over-current protector or disconnect device between battery and inverter. Nobody answers your emails , calls or whatsapp messages. Stay away from this company. Watch out they may operate under a different name as they still advertise. See the Powerforum and ask there if your installation is safe. I had my installation coorected at my own expense. only to find out the the narada batteries are no good. STAY AWAY.
