1.2 Target Audience This manual is intended for anyone who uses Autarco inverters in conjunction with a Power Export Limiting Device (PELD). Before any further action, the operators must first read all safety regulations and be aware of the potential danger to operate high-voltage devices. Operators must also have a complete understanding of this device’s features and functions. -
Page 6: Intended Application
1.3 Intended Application This manual applies to the following products; ● S2.PELD10-MII For limiting up to 10 inverters at a time ● S2.PELD80-MII For limiting up to 80 inverters at a time Please note that all current inverter models excluding the UX Series are capable of internal power export limitation using an external current clamp or consumption meter. -

PELD is listed below: Grid AC voltage sampling terminal CT1/2/3 AC current sampling terminals (CT1 only when 1 phase) Comm_INV Communication with Autarco inverter Communication Connection for Monitoring Device or Software Upgrade Stick Figure 4.5: Three-phase system with Autarco S2.PELD-MII... - Page 12 Figure 4.6: Three phase system with Autarco PELD Figure 4.7: Single phase system with Autarco PELD Note that the PELD shall be installed near the measuring point for current/voltage. The CT cables and grid input cable are usually limited in length. In order to shorten the length of CT and grid input cable, the PELD is recommended to be installed near the customer distribution box.

Page 13: Make The Grid Input Cable
Measure the distance from PELD to power distribution box. Choose the proper cable for grid input. Use a 5-core cable for Autarco 3 phase PELD and a 3-core cable for Autarco single phase PELD. Check carefully the connections in the connector and make sure the cables inside the connector cannot touch each other. -
Page 14: Make Rs485 Cable (Comm-Inv Port)
4.5 Make RS485 cable (COMM-INV port) ● Refer to figure 4.16, the RS485 terminals for inverter and PELD are already assembled. RS485A is 2 connected to yellow and RS485B to blue wire. Suggested RS485 cable: preferred 0.5-1.0mm ● Refer to figure 4.17, connect communication cable between inverter with PELD, and then measure the distance from PELD to inverter. -
Page 15: Connect Ground Cable
● Follow step1 to assemble 2 connectors to each end of the cable. If the RJ45 comms ports are used on the inverter, you also may use standard Ethernet cables for connection from one inverter to the second one and so on. Then you only need to assemble one cable from the last inverter to PELD. -
Page 16: Connect The Grid Input To The Distribution Box
● To prevent overheating, always make sure the secondary side of the CT’s is connected to the PELD before switching on power. In figure 4.20 a few examples of Current Transformers can be found. It is possible to select your own brand and type as long as they meet the requirements and safety standards. -
Page 17: Monitoring
4.10 Monitoring Inverters that are connected to the PELD can be monitored by Autarco Ethernet/WiFi/GPRS stick or box. WiFi/GPRS stick is used for single inverter monitoring. Multiple-inverters must use WiFi/GPRS box to monitor via the PELD. Digital Monitoring Sticks (with “-D”... -

Failsafe settings determine how the inverter operates if there is a loss of connection with any device. There are 3 error modes ● RS485 AllFail: PELD has lost communication with ALL inverters ● RS485 Fail: PELD has lost communication with one or more inverters ●... -
Page 26: Peld On/Off
Figure 6.16: Mode 01 Mode “02” is the per phase limiting mode. In this mode the export power is 0 on each phase. The inverter will generate a power equal to the lowest load power. See the example in figure 6.17: the inverter only generates the power that equals to one of three-phase loads that has the lowest load power of a certain phase (here 4000 W). -
Page 27: System Upgrade
Switching PELD on: the device can monitor and manage the working condition of inverters in real time, and it prevents backflow generated. Switching PELD off, means the device shuts down the function of controlling backflow power. 6.4.8 System Upgrade The upgrade of PELD’s system can be realized through the RS485 communication port with an upgrade stick. -
