fault problems and how to fix

I have the EB3A first rime out of the box 65% charged so fully charged it via mains supply as I was going away for 3 days. when I got to my destination went to use the device no power at all so only other source I had was the solar panel which I purchased at the same time plugged in showed as charging for 2 mins then nothing. now I am back home plugged into the mains and get 3 fault messages.
