I have just purchased 2 of these 5.6Kva Mecer 5M4 inverters. The one operates using the 4.8Kwh Mecer Battery Rack and the other operating on 4 x 200Ah Lithium-Ion batteries. They are installed at 2 different clients and they are both doing the exact same thing. They randomly reset for about 15 seconds while Mains power is on. Also went through all the settings and cannot find a solution. I also need assistance regarding this error.
