1.1. Introduction

This manual provides information on functionality and maintenance of the Protect PV solar inverter.

Illustration 1.1: Protect PV 10 kW, Protect PV 12.5 kW, Protect PV 15 kW

CE marking - This certifies the conformity of the equipment with the regulations which apply in accordance with the directives 2004/108/EC and 2006/95/EC.

The Protect PV inverter series comprises:

Protect PV easy

1.2. Operation Mode Definition

Off grid (LEDs off)

When no power has been delivered to the AC grid for more than 10 minutes, the inverter disconnects from the grid and shuts down. This is the normal night mode. The user and communication interfaces are still powered for communication purposes.

Connecting (Green LED flashing)

The inverter starts up when the PV input voltage reaches 250 V. The inverter performs a series of internal self-tests,including PV auto detection and measurement of the resistance between the PV arrays and earth. Meanwhile, it also monitors the grid parameters. When the grid parameters have been within the specifications for the required amount of time (depends on country settings), the inverter starts to energise the grid.

1. Introduction

On grid (Green LED on)

The inverter is connected to the grid and energises the grid. The inverter disconnects if: It de- 1 tects abnormal grid conditions (depending on country settings), if an internal event occurs or if

no PV power is available (no power is supplied to the grid for 10 minutes). It then goes into connecting mode or off grid mode.

Fail Safe (Red LED flashing)

If the inverter detects an error in its circuits during the self-test(in connecting mode) or during operation, the inverter goes into fail safe mode. The inverter will remain in fail safe mode until PV power has been absent for a minimum of 10 minutes, or the inverter has been shut down completely (AC + PV).

Refer to the section on Troubleshooting for further information.
