The PVS980-58 is a central inverter designed for solar power systems. It converts, adjusts, and conveys power generated by a solar generator to the electrical power system. The inverter operates through various machine states including Initialize, Disconnected, Connecting, MPPT, and Night Q production. It features grid code settings for different countries, grid monitoring to ensure grid stability, and various control functions such as reactive power control and active power limitations. The inverter can be controlled locally via a control panel or remotely through fieldbus interfaces. It also supports PC tools for firmware updates, configuration, and monitoring.
Troubleshooting and error codes
| Code in Dec (Hex) | Fault | Cause | What to do |
|---|---|---|---|
| 11776 (0x2e00) | Overcurrent | Output current has exceeded internal fault limit. | Check: • AC connection • Grid failure • Transformer failure • Inverter main circuit failure. |
| 11778 (0x2e02) | Short circuit (This fault cannot be reset.) | Short-circuit in output. This fault requires a reboot of control unit either by switching the power off and on, or using parameter 196.08 Control board boot. | Check: • there are no power factor correction capacitors in output • the inverter main circuit failure. If fault persists, contact your local FIMER representative. |
| 11781 (0x2e05) | BU current difference | Current difference detected by branching unit. | Check: • current difference between power modules • power module internal fault. If fault persists, contact your local FIMER representative. |
| 15876 (0x3e04) | DC link overvoltage | Intermediate circuit DC voltage has exceeded. | Contact your local FIMER representative. |
| 15878 (0x3e06) | BU DC link difference | Difference in DC voltages between parallel-connected power modules. | Contact your local FIMER representative. |
| 24071 (0x5e07) | PU communication | Maximum charging time exceeded or connection to BAMU/power modules is not functional. | Check • charging fuses and resistors • the fuse in auxiliary power board of the power module • fiber optic cable connections. If auxiliary code is 7, check the connection to BAMU. |
