Hello. I had a Sunsynk Lifelynk installed a few months ago. Haven't really had to use it due to no load shedding. However, this week we had a power outage. The batteries did not kick in and there was rapid battery voltage loss. Does not seem to be charging from the grid properly. No solar panels. What could be wrong?
