  If the Load Status LED Indicator is red and flashing fast, and there's no output voltage at the Load Terminals, it means there is a short circuit. Clear the short circuit and then press the Load On/Off Button (4). After 3 seconds, the output voltage at the Load Terminals should be restored, and the load will start operating normally again.

  If the Load Status LED Indicator is red and flashing slowly, and there is no output voltage at the Load Terminals, it indicates that the current drawn from the Load Terminals exceeds 10A. Reduce the load to below 10A and press the Load On/Off Button (4). After 3 seconds, the output voltage at the Load Terminals will be restored.

Why is the Battery Status LED Indicator (2) Green and flashing fast on my SamplexPower MSK-90?
- A

  The Battery Status LED Indicator (2) flashes green rapidly because the battery voltage has risen to the Over Voltage Disconnect Threshold of 16.0V. Measure the battery voltage; if it is higher than 16.0V, disconnect the battery. The controller is defective, so call Technical Support.

  The Battery Status LED Indicator being steady orange indicates that the battery voltage has dropped to the Under Voltage Warning Threshold of 12.0V. The Battery Status Indicator will return to green when the battery voltage rises to the Under Voltage Warning Reconnect Threshold of 12.2V.

How to fix Charging Status LED Indicator (1) being OFF on SamplexPower MSK-90?

  If the Charging Status LED Indicator is off during the day when the PV panels are in direct sunlight, it means the input connection from the solar panels has been disconnected or the PV Voltage is less than 5V. Check that the wiring from the solar panels to the Solar Panel Input Connections is connected and tight. Also, verify that the PV Voltage is greater than 6V.
