12 5. Start & Stop 5. Start & Stop 5.1 Start the Inverter To start up the Inverter, it is important that the following steps are strictly followed: 1. Switch the Grid Supply Main Switch (AC) ON first. 2. Switch the DC disconnect switch ON. If the PV array (DC) voltage is higher than the inverter's Start Up Voltage, the inverter will turn on. The red DC POWER LED and LCD will light (continuous). 3. The Ginlong inverters are powered from the DC side. When the inverter detects DC power that is within start-up and operating ranges, the inverter will turn on. After turn-on, the inverter will check internal parameters, sense and monitor AC voltage, hertz rate and the stability of the supply grid. During this period, the green OPERATION LED will flash and the LCD screen shows INITIALIZING. This tells the operator that the inverter is preparing to generate ac power. 4. After 300 seconds (IEEE-mandated, US systems), the inverter will start generating AC power. The green OPERATION LED will light continuously and the LCD screen will show GENERATING. 2. Wait ~30 seconds (AC side capacitors are dissipating energy and the ac connection terminals will go to zero volts). If the inverter has DC power within the MPPT operating range, the red POWER LED will be lit. After waiting for the AC side of the inverter to de-energize, switch the DC disconnect switch on the bottom of the inverter to OFF. Switching the DC disconnect switch to the right or to the left will disconnect the inverter from the DC power source. All LED's will switch OFF within one (1) minute. WARNING: Although the inverter DC disconnect switch is in the OFF position and all the LED's are OFF, operators must wait 5 minutes after the DC power source has been disconnected before opening the inverter cabinet. DC side capacitors can take up to 5 minutes to dissipate all stored energy During normal operation LCD shows the current status of the inverter. The screen will display current power generation, total generation, a bar chart showing ac power generation over time, etc. Press the button labeled ESC to switch from home dashboard, i.e. the initial interface for owners and operators, to other screens showing details of daily and monthly generation.

22 7. Maintenance 8. Troubleshooting The Solis US Three Phase series of inverters do not require any regular maintenance. However, cleaning the dust off the heat sink will help dissipate heat away from the inverter and this will increase the lifetime of the inverter CAUTION: Do not touch the surface when the inverter is operating. Some parts may be hot and cause burns. Turn OFF your inverter (refer to Section 5.2) and let it cool down before you do any maintenance or cleaning of inverter. Alarm Message No power LCD show initializing all the time Failure description Inverter no power on LCD can not start-up Solution 1.Check PV input connections 2.Check DC input voltage (single phase >120V, three phase >350V) 3.Check if PV+/- is reversed 1.Check if the connector on main board or power board are fixed. 2.Check if the DSP connector to power board are fixed. The LCD and the LED status indicator lights can be cleaned with a soft cloth if they are too dirty to read. OV-G-V Over grid voltage 1.Resistant of AC cable is too high.
