Sunny Islands generally need a battery bank to function correctly. Your batteries are the one thing that can be damaged/ruined in days or hours if they are not managed correctly.Get a volt meter and measure your battery bank voltage and make sure that it is getting properly charged (not overcharged or over discharged).Once your battery bank condition is known/stabilized, then you can start working on the rest of the issues.Doing things like measuring the AC line voltage (and frequency--especially for genset power) is a starting point (if AC line is out of proper operating range, Grid Connected systems will generally shut down until proper conditions are restored).I guess you are in Nigeria? Do you have an installer?The SMA systems are highly configurable, and should be displaying error codes/functions somewhere. I may be of limited help, but we would need a lot more information about your basic setup and what is happening. Has the system been working and is now failing, or is this a new install?Take care,-Bill
Thanks a lot Bill!!
