Good Sales Service With Clear Information With Strict Controls To Prevent A Hard Sell But Very Poor Knowledge About Battery Installation And Very Poor After-Sales Service. The information provided about the solar panels was excellent and a good survey was carried out to check the suitability. The installation looks to be good quality and they coped well working with our builder who was doing our drive at the time. Safety, as reported by our retired Nuclear Electric Safety Manager neighbour, was not up to the current standards but the I do think these are rather excessive. Battery installation was not as specified in the battery installation manual, and the parameters for operation do not appear sensible, according to the battery's manual. So far it has taken 18 months for them to investigate. Initially EEC insisted that the battery manufacturer documented incorrect installation options in their manual, then suggesting maybe they may be right to some extent, then suggesting another option, not in the manual, and requesting photos of how they actually installed the batteries. This was after not providing any updates, apparently loosing the cases. I highlighted "time of the essence" which legally requires them to solve the problem without delay but this failed to produce any action. After requesting to talk to the support agent's supervisor last week there has been some action, initially the supervisor continued to assert that the batteries were installed correctly and the manufacturer had confirmed this. Subsequently they rang back to say the batteries had not been installed correctly and the Operation Director (Ewen) would call me to arrange action to address this including re-validation of the warrantee. He also agreed to address the issue of the parameters for operation although his view was that the inverter has default settings and that is all they use. He explained it with the example of a car: just because it is capable of 100 mph does not mean you always need to drive it at 100 mph. The implication is that there is nothing wrong with the garage using a speed limiter, with a PIN, to prevent it doing more than 50 mph as this will help reduce warrantee claims. I will update this if they do indeed carry out any action to rectify the issues highlighted and am hopeful we have turned a corner. They also failed, when requested by email numerous times, to provide a link so I could update my original glowing review :( This review only comes to you as I have twice contacted * Reviews and provided proof I had bought the installation.
