Happy to sell but poor after-sales service

From the start my inverter has not worked properly. At least once a month it just switches off solar power to the battery once it's charged and then the battery just drains, even when the sun is shining. I've reported this several times and each time the response from Beryl, their manager, is "I've sent it to the technical team and they will get back to you" but I never hear back from them. It's obvious the inverter is faulty and they should replace it, but they refuse to.

I strongly recommend looking elsewhere for your solar needs. Aztec seems very busy doing new installations but apparently has no time to attend to existing customers.
