I have mutiple Victron Energy MPPT 75/15 Solar controllers in Solar Battery systems that I operate in Australia. I have a serious issue with many of them that I need help with.
Many of the systems are just switching off the load output. When we go to the system and open the application to access the solar controller it them prompts for a software update v2.23 to v2.25 once this update is done it then prompts for the update v1.46 to v1.50. The power / load output immediately works as it should do.
The issue I have is that the update is not storing in the solar controller and this issue is repeatedly happening in the same solar controllers.
- They are not remembering the software/firmware update to V1.50
- They switch off the load output while in the field for no reason.
