BEFORe you start Congratulations on purchasing your Protect PV 4600 Grid PV-Inverter from AEG Power Solutions GmbH referred to in this manual as “PV-Inverter”, or simply the “device”). This PV-Inverter is a highly reliable product due to its innovative design and perfect quality control. The device is dedicated to high-demand, grid-linked PV systems. This manual contains important information regarding installation and safe operation of this unit.
safety instructions risk of electric shock 1. Do not remove the casing. Protect PV® contains no user serviceable parts. Refer servicing to qualified service personnel. Both AC and DC voltage sources are terminated inside the PV-Inverter. Please disconnect these circuits before servicing. 2. When a photovoltaic panel is exposed to light, it generates a DC voltage. When connected to this equipment, a photovoltaic panel will charge the DC link capacitors. 3.
limited warranty The limited warranty provided by AEG Power Solution (“AEG PS”) in this Statement of Warranty applies only to Equipment purchased for residential, commercial or industrial use in the ordinary course of the business. terms of warranty AEG PS warrants that it is sufficiently experienced, properly qualified, registered, licensed, equipped, organized and financed to perform the Work in compliance with the terms of this Agreement.
accidents brought about by the Purchaser‘s actions, such as negligence, connection error, failure to follow instructions for maintenance, abnormal use due in particular to electrical or mechanical overload. Any parts furnished under this warranty may be new or factory-remanufactured. Repair or replacement of a defective Equipment or part thereof does not extend the original warranty period.

3. INSTALLATION INSTRUCTIONS OPENING THE PACKAGE After opening the package, please check the contents of the box. It should contain the following: 1. One Protect PV inverter 2. Instruction manual 3. One mounting frame 4. 4 mounting screws 5. 2 safety-lock screws 6. One AC socket assembly for Protect PV 2000 and 2800 BEFORE Installation Before starting installation please consider the following items: This unit is designed for indoor usage. Do not expose the unit to wet, or moist conditions.
mounting Protect PV to the wall 1. Select a wall or solid vertical surface that can support the PV-Inverter. 2. P rotect PV requires adequate cooling space. Allow at least 20cm space above and below the inverter. 20 cm space 20 cm space 3. U sing the mounting frame as a template, drill 4 holes as illustrated in the following figures. 4. F ix the mounting frame as the figure shows. Do not drive-in the screws flush to the wall. Instead, leave 2 to 4mm exposed. 5.
6. Check the installation conditions a) Do not install the PVInverter on a slanted surface b) Check the upper straps of PV-Inverter and ensure it fits on to the bracket c) Insert safety-lock screws to the bottom leg to secure the inverter. Check the secure mounting of the PV-Inverter by trying to raise it from the bottom. The PV-Inverter should remain firmly attached. Select the installation location so that the status display can be easily viewed.
Connecting to the grid (AC utility) 1. Measure grid (utility) voltage and frequency. It should be 230VAC or 220VAC), 50/60Hz, and single phase. 2. Switch off by breaker or fuse between PV-Inverter and utility. 3. For Protect PV 2000 and 800, connect AC wires as follows: • Disassemble female socket. • Connect AC wires to connection socket as indicated.
• Connect Phase to pin 1, Neutral to Pin 2 and PE to Pin • Assemble the socket again and attach. • Twist the coupling ring to the PV-Inverters receptacle. Make sure it is correctly matched. To prevent risk of electric shock, ensure that PE is properly grounded before operating the PV-Inverter. 4. Suggested wire-cross section or AC wire model diameter Ø (mm) area (mm2) awG no.
Connect to PV Panel (DC input) 1. Make sure the maximum open circuit voltage (Voc) of each PV string is less than 450VDC UNDER ANY CONDITION. We recommend Voc less than 360VDC with ambient temperature of 25C. 2. Use MC 3 (Multi-contact) connectors for PV array terminals. 3. Connect the positive and negative terminals from the PV panel to positive (+) terminals and negative (-) terminals on the PV-Inverter.
4. SySTEm diagRam The typical connection diagram for the entire PV system is shown in the following figure. 1. Pv-Panel: Provide DC power to Protect PV inverter 2. Protect Pv PV-inverter Converts DC (Direct Current) power from PV panel(s) to AC (Alternating Current) power. Because Protect PV is grid-connected it controls the current amplitude according to the PV Panel power supply. Protect PV always tries to convert the maximum power from your PV panel(s). 3.
5. Operating Your PV-Inverter Modes of operation There are 3 different modes of operation. 1. Normal mode: In this mode, Protect PV works normally. Whenever the supplied power from PV panel is sufficient (voltage>150VDC), Protect PV converts power to the grid as generated by the PV panel. If the power is insufficient, (voltage<120VDC) Protect PV enters a “waiting” state. Whilst “waiting” Protect PV uses just enough power from the PV panel monitor internal system status.
• Normal operation: When PV string DC voltage is greater than 150V, Protect PV operates in the normal state. In this state, it feeds power to the grid. Protect PV automatically stops when the PV power is not enough. a. Press the “Function” key repeatedly until “Contrast” shows in the display. b. Hold the “Function” key down for more than 2 seconds, until display shows “Set contrast” and a bar graph on the right. c. Press the “Function” key repeatedly until the display’s contrast is acceptable. d.
maximum power point trackinG (mppt) A good PV inverter must be able to convert the maximum power from any PV panel. Due to its advanced design, Protect PV PV-Inverter can track the maximum power from your PV panel in any condition. When the displayed power on the LCD output does not change dramatically, Protect PV inverter is converting the maximum power from panels. When the LCD power reading is significantly changes, Protect PV is tracking the power according to the varied sunlight.
6. Inverter Status Protect PV is designed to be user-friendly; therefore, the status of the Inverter can be easily understood by reading the information shown on the front panel display. All possible messages are shown in the following table. Display information Operating conditions Message Description Power off No display PV inverter is totally shutdown, VPV <=70V Standby STANDBY 90V< Input voltage < =100V Normal Working Status Input voltage range 100~150V during start-up.

7. COmmuNiCaTiONS Protect PV is equipped with a powerful communications interface and options. Use Protect PV Monitor to monitor the status of your PV Inverter. Also, qualified personnel can upgrade the firmware using the RS232 port. 1. RS232: To use the RS232 port, remove the RS232 cover on the bottom side of Protect PV. It is a DB9 socket. The pin definition is pin 1 2 3 4 5 6 7 8 9 functional description n.C. TxD RxD n.C. Common n.C. n.C. n.C. n.C. n.C. means “no Connection” 2.
3. Firmware upgrade: To keep the firmware up to-date, use the RS232 port and supplied program to upgrade firmware. To do this, please contact your local AEG PS service To prevent risk of damage it is recommended that only authorized personnel perform firmware upgrades.
8. Trouble shooting In most situations, the Protect PV inverter requires very little service. However, if Protect PV is not able to work perfectly, please refer to the following instructions before calling your local AEG PS dealer. • Should any problems arise, the red (Fault) LED on the front panel turns on and the LCD displays the relevant information. Please refer to the following table for a list of potential problems and their solutions.
Inverter Failure 27 1. Check the open PV voltage, see if it is greater than or too close to 450VDC PV over Voltage 2. If PV voltage is less than 450VDC, and the problem still occurs, please call local service 1. Disconnect PV (+) or PV (-) from the input, restart the PVConsistent Fault Inverter 2. If it does not work, call service 1. The internal temperature is higher than specified normal value 2. Find a way to reduce the ambient temperature. Over Temperature 3.
