I am attempting to know which type of maintenance should be expected in case I installHMS Photovoltaik. Under the conventional systems, I have been told that inverters are usually replaced after every 10-12 years. Micro-inverters are alleged to have longer life and have long warranties, usually 2025 years. But are there things I need to be cautious of e.g., loose cables, failed modules, software problems? What is your cleaning / check-up frequency of the system? I hope it would be actual experiences of the existing owners.
