I read two threads about the same error #28, but posting my question to ask an additional help. Following is my solar setup, it worked perfectly fine for few days. But it failed with MPPT error code #28, yesterday first time, as suggested in document I disconnected all the wires and then re-connected them again. It worked for few hours and failed again with same error code #28 today. Appreciate your help in advance.
1) How do I get a replacement? The solar-biz.com from where I purchased all the devices said I should send it to Victron Energy directly. I am in Arizona, USA, can someone help me how do I return and get a replacement device?
2) Is there any further debugging or fix I can implement to make my setup work? It seems getting a replacement device will take couple of days to weeks.
