(CPLD Fault)
Recommended solutions:
1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace Control Board or inverter

Maintenance and Decommissioning of Inverters
This section defines the activities required to properly maintain the inverter and must be done by qualified personnel,
trained in the installation, decommissioning and maintenance of PV inverters.
7.1
Product Maintenance
Maintenance is required to ensure the inverter remains in proper condition, prolonging service life and preventing
potential issues.
Check Electrical Connections
7.1.1
Check all conductor connections as regular maintenance inspection every 6 months to one year, depending on the
temperature changes at the installation site.
Check the conductor/cable connections. If loose, tighten all the terminals to proper torque, referring to Chapter 3
Installation.
Check for damage to the conductor/cable jacket. Repair or replace any damaged conductors/cables.
Clean the Air Vent Grate
7.1.2
The inverter can become hot during normal operation. It uses built in cooling fans to provide sufficient air flow and to
help in heat dissipation.
Check the air vent grate regularly to make sure it is not blocked. Clean the grate with a soft brush or vacuum cleaner
attachment if necessary. The frequency of this cleaning depends on the installation environment.
Replace the Cooling Fans
