Performing General Maintenance
Follow these simple routines to ensure many years of service and optimal performance of your solar energy system.
1. Keep the heat sink clear of dust and debris.
WARNING: Shock and fire hazardDo not use a pressure washer to clean the GT Inverter, or use other cleaning methods that could allow water to enter the unit.
2.Clean the PV array with flowing water whenever it is visibly dirty, during a cool time of the day.
3.Periodically inspect the system to make sure that all wiring and supports are securely in place.
4.On a sunny day near noon on March 21 and September 21 of each year, review the output of the system and compare it with the previous year’s reading. Maintain a log of system performance readings so that you can recognize when system performance becomes inconsistent.
