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: ● S2.1P-PELD10-MII For limiting up to 10 single phase inverters at a time ● S2.3P-PELD10-MII For limiting up to 10 three phase 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 (for 1 phase, only use CT1) Comm_INV Communication with Autarco inverter Communication Connection for Monitoring Device or Software Upgrade Stick Figure 4.5: Three-phase system with Autarco S2.3P-PELD-MII... - Page 12 Figure 4.6: Three phase system with Autarco S2.3P-PELD-MII Figure 4.7: Single phase system with Autarco S2.1P-PELD-MII 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 the 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 the PELD to the mains 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. Carefully check 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 connected to yellow and RS485B to blue wire. Suggested RS485 cable: preferred 0.5-1.0mm ● Refer to figure 4.17, connect the communication cable between the inverter and the PELD, then measure the distance from PELD to inverter. -
Page 15: Connect The 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. ●... -

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. Autarco has a limited number of 300 : 5 Current Transformers in stock and they must be ordered separately. Check space requirements in your installation. -
Page 17: Multiple Inverter Connection
Before starting up the inverter, please follow 6.5.1 to set the inverter number in the PELD. 4.10 Monitoring Inverters that are connected to the PELD can be monitored by Autarco Ethernet/WiFi/GPRS stick or box. WiFi/GPRS/Ethernet stick is used for single inverter monitoring. In case of a single inverter, always check if using the internal PELD function with an external meter is an alternative. -

Note: it is possible that NG will be shown when the current-transformer is connected correctly if the cable is smaller than designed for. Make sure the cable lies centralized in the core for proper reading. For the single phase S2.1P-PELD10-MII only one CT is shown. 6.3.3 Software The screen shows the model version and the software version of the PELD. -

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 power equal to the lowest power of the three phases (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. -
Page 28: Set Inverters
The PELD is available with different operation modes. To make sure that the inverters can work with the MII version, set the inverters into the correct operation mode. Notice: If you are using S2.PELD10-MII, select 5G EPM Notice: If 5G EPM is chosen, all inverters produced before Nov 30th 2019 need to update the firmware. -
