Poor customer service and poor warranty experience
Our Growatt inverter died after 4 years (within warranty). It took Growatt 2 months to find a suitable replacement unit for us. During that time, we had to buy energy from the grid, during the hottest part of summer with 30+C temperatures and our ducted aircon uses a lot of energy. Despite their warranty quoting Australian Consumer Law where it says that they will compensate for losses under the warranty, they are flat-out refusing to compensate us for the energy we bought to cover the time where they couldn't supply a replacement inverter, which is unlawful. Also, the replacement inverter doesn't come with a new warranty - it continues the warranty from the original inverter, which means if our replacement inverter also dies in the next 4 years we are out of luck and would have to buy a whole new inverter. Also, the replacement inverter didn't come with a dongle to transmit information to the related app to monitor usage and any outages, which the original inverter came with, so we don't consider that a like-for-like replacement. All in all, the experience has been very poor and we're once again warned about using inferior-quality hardware as it's rarely worth it.
