NO BACKUP, DON'T EVEN KNOW EACH INVERTER REQUIRES ITS OWN ****LE, NO COMMUNICATION

After many messages and phone calls and weeks later I still do not have my COC, missing ****le and by the looks of it system has not been properly earthed. Stay away if you want a problem free job and don't have to pay someone else to come fix the issues and have to litigate to get your money back for that
