Goodwe Inverter Issues

Goodwe Inverters and the Goodwe support company should be approached with caution if my experience is anything to go by. I worked through their suppliers and installers in 2018 before Solar became the in thing. All was well and the inverter worked well until now. We are 4 months away from the end of the warranty period expiring and unit starts giving problems. My supplier and installer tries his best and follows Goodwe SA instructions. No change! The unit carries on with intermittent shut downs. Emails to Goodwe contact centre - I receive a “ticket number” and am told I will be contacted. I have stopped holding my breath. Looks like Goodwe will not honour their Warranty obligations as I get no response, let alone good news from them. So - beware of Goodwe and their products!
