November 26, 20196 yr Hi guys, I have a solar system of around 9 kW of panels with two Apex inverters. Associated is approximately 20 kWh of battery capacity. The system runs great for the most part. However, one of the issues we are finding is that during cloudy weather the system will switch off the power for a second or two and then the power comes back on. It happens a few times during the day when the weather is cloudy. The system is set to "SBU". Does anybody have any ideas as to what could be causing this? Any and all help much appreciated.

Sounds like the low voltage cutoff being triggered, as soon as it switches off, the voltage returns to above the setpoint and the inverter switch on again.
