7.0 Troubleshooting and Inverter Messages

Identifying and resolving faults

The PVI 3000S-5300 is fitted with a self-diagnostic system, which can recognize a majority of

possible faults and show these on the display. This allows the operator to rapidly identify possible

problems in the solar inverter or system. Please refer to Table 7.1.1 for a thorough explanation of

fault codes, modes, etc. These indicate both internal errors and external faults.

Ground Fault

If a significant ground fault occurs in the PV array or wiring, the Ground Fault LED will light and

the “fault” will be displayed. The GFDI fuse (located on the wiring/connector panel) may be

blown. If it is, determine and repair ground fault and replace fuse with Bussmann KLKD1 (1 Amp,

600VDC).

WARNING: In the event of a ground fault, DO NOT TOUCH any equipment (including,

but not limited to: the inverter, the PV array disconnects, the PV array combiners, the

PV panels, the PV racking system). Immediately contact the installer or another

qualified person to locate and repair the source of the ground fault. Be aware that

normally grounded conductors and equipment may be energized and may pose a

significant shock and / or fire hazard.

Weak Sunlight Condition

Operation in weak sunlight, (for example early in the morning, when overcast, or when snow is

covering most or all of the PV array) can cause the inverter to go through a cycle of trying to start

and restart several times. This can occur if the array reached 235V (strike voltage) but there is

nearly no power available. If in doubt, wait for stronger sun.

7.1 Inverter Messages

Explanations of Error Messages

In the event of a fault, the inverter will stop feeding the AC voltage to the building/utility and

display the error message on the LCD. Qualified service personnel shall do the analysis,

measurement, and debug the system if needed according to the error message in order to

resume normal operation. It is recommended to analyze the fault condition(s) by referring to the

table below and then remove the fault condition(s) in order to return the inverter to normal and

continue to feed AC voltage to the utility steadily. Please contact Solectria Renewables if the

same error message is persistent.
