********** after sales support

It's such a disappointment that I have to come to this forum to get some (or hopefully get some) feedback. I have had my solar for less than a year and it has been an absolute nightmare. I have spent numerous time on the phone with their support to get absolutely nowhere. Never mind the tickets I submit that fall in the ether. I am having constant problems with my battery going offline and most of the time I have to feed from eskom so I can just have a day with no tripping. The inverter itself is constantly throwing out errors, the sound itself coming from the inverter is constantly doing some type of internal switching over. it's been an absolute nightmare. Each time I call their support, they say they are going to login to my system remotely and make changes to fix the problem or update the firmware, telling me they will phone me back with an update. I have never received a call back from them with feedback. I simply need someone to come out and assess the setup, it's not that difficult. Honestly, it's **********.
