Field Service GuideCommon field service procedure: (Fill in the Field Service Form) (Create a

field service form)1. Record the user’s information: Owner's name, Address, phone, email2. Service technician name, company, service date3. Record the inverter’s serial number.4. Number of panels in string A, number of panels in string B5. Record the panel’s information (Voc, Isc, Vmp, Imp, Power, Temp. Coeff.

Manufacturer, model number). Check the system configuration.6. Check the correctness of the system configuration (use the quick assessment

way)7. Check the DC isolator, AC isolator and wire connection.8. Check the grid voltage against the specification on the inverter label. Contact

the utility company if the voltage is beyond the specification. 9. Check the DC voltage range. It should between 150 to 400V.10. Restart the system: First switch off the AC, then switch off DC. Wait for at

least 10 min. before you open the inverter’s cover. This allows the internal capacitors to discharge.

11. Open the Cover. (Follow the Inverter Open Procedure.)12.Do service work.13.Upgrading procedures (example: replace fuse)• Replace the water sealing gasket• Reinstall the cover after service . (Follow the Inverter Cover Installation

Procedure.) 7“Aero‐Sharp confidential. Do not distribute without permission from Aero‐Sharp ”

Cover Installation Procedure

1. Plug in and fully lock the display ribbon cable, then connect the cover grounding wire.

2. Make sure the water-sealing gasket sits properly along the edge of the inverter box when install the cover. This is important for avoiding water-leakage.

3. Slightly tighten the four screws following diagonal order, then make the last few turns one by one.

4. You should be able to touch the tip of the screw from bottom but not allowing the screw tip protrude the screw hole.

Gird Volt Error1. Check the grid voltage against the specification

on the inverter label.

2. If the voltage is within the specification range, open the inverter cover.

3. Measure the white resistor (see right picture). If the resistance is beyond 32-34Ω，replace the inverter.

4. Otherwise, measure the fuse. If it is broken, replace it. Select the proper fuse from the chart.

5. If the fuse is good but the problem stays, replace the inverter.

“System Error” (may have other errors together) or “Grid Freq Err” or “Please Wait”

1. Check the system configuration.

2. Turn off and turn on the inverter. If the problem stays, open the inverter cover.

3. Replace the control board with the suitable software version. Pay attention to the pins underneath.

4. Replace the driver ribbon cable and the display ribbon cable. Make sure the connectors are fully locked.

3. Reinstall the inverter. If the problem stays, replace the inverter.

TVS components need be replaced



Replace the TVS component1.The hole position of TVS at DC side as right figure. The number starts from 1 to 10 (count from the left side). The hole used for one TVS should be 1-2-5, and other TVS will be 6-9-10 as right below figure.Hole 1 and hole 10 are for the pins of safety fuse (the slimmer pin).Replacement method: Replace with the qualified DC TVS in accordance with the correct hole position. TVS Pin No. 1 2 3 3 2 1 TVS Hole No. 1 2 5 6 9 10

2.Restart the system. Replace the controlboard if the problem still exists.

3.If the problem still occurs, replace the inverter.
