The sals team and installers are wonderful, but when things go wrong it is a different story. EEC Solar persuaded me to buy a very expensive Tesla battery to store electricity for my own use when the sun goes down. They also told me that they would be monitoring my site periodically to see if everything is OK. I have just discovered that the monitoring went offline in November 2017. I called Solaredge as EEC Solar wouldn't return my calls and they told me that I have an error code that means the battery isn't working. Also, although EEC Solar emailed me instructions how to get my wifi connection with the solar panels working again, this would mean I would have to take off the front of the inverter to get to the installer menu and this is highly dangerous and they do not want home owners to do this. I have left several messages with EEC Solar for the Director or customer services to get back to me - but they won't! The customer services lady leaves at 3pm and seems to be inundated with problems to sort out!
