5 Electrical Connec�on 5.1 DC input terminal connec�on 1. Switch the Grid Supply Main Switch(AC)OFF. 2. Switch the DC lsolator OFF. 3. Assemble PV input connector to the inverter. Warning: When using PV modules, please ensure the PV+ & PV- of solar panel is not connected to the system ground bar.
Page 16
The steps to assemble the DC connectors are listed as follows: a)Strip off the DC wire about 7mm, disassemble the connector cap nut (see picture 5.3). Pic 5.3 Disassemble the connector cap nut b) Crimping metal terminals with crimping pliers as shown in picture 5.4. Pic 5.4 Crimp the contact pin to the wire c) Insert the contact pin to the top part of the connector and screw up the cap nut to the top part of the connector.

DC input current should be 20A. if exceeds, it may damage the inverter and it is not covered by Deye warranty. 5.2 AC input terminal connec�on Do not close the DC switch a�er the DC terminal is connected.Connect the AC terminal to the AC side of the inverter, the AC side is equipped with Three phase AC terminals that can be conveniently connected.
Page 18
The AC output connector is divided into three parts: matching socket, sleeve and sealing- sleeve, as shown in picture 5.7, the steps are as follows: Step 1: Remove the cable sealing ring and sleeve in sequence from the AC connector. Step 2: Use strippers to strip the protec�ve sheath and insula�on layer of the AC cable to the right length, as shown in Picture 5.8.

5.3 The connec�on of the ground line Good grounding is good for resis�ng surge voltage shock and improving EMI perfor- mance.Therefore, before connec�ng AC, DC and communica�on cables, you need to ground the cable firstly. For a single system, just ground the PE cable. For mul�ple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to ensure the equipoten�al connec�on.
Page 21
In order to protect the inverter AC connec�on, it is recommended to install a circuit breaker to prevent overcurrent. See table 5.3 below.

5.6 Installa�on of datalogger When the inverter is out of the factory, the installa�on loca�on of datalogger is sealed by a sealed plate as shown in Picture 5.13. When installing the datalogger, remove the sealing plate, replace it with the sealing plate with square hole in the accessories, and �ghten the screws. Insert the datalogger into the interface and fix it with a screw.

7. Zero-export func�on via energy meter There're two kinds of energy meters for this series inverter. First type is Eastron SDM630-Modbus V2 which is able to measure the Max. 100A current directly. More details please refer to Pic 7.1 & 7.2. For the Eastron SDM630 MCT 40mA, it needs external CT to measure the current.

7.1 Mul�ple strings and parallel connec�on meters This applica�on is that when the string inverters work in parallel, there is only one power grid and one load, and only one meter can be connected to prevent reverse current, so only this many-to-one an�-reverse current connec�on can be connected. If there’s several inverters in a plant, also it can use 1pcs meter to realize zero export func�on.For example,if there’s 3pcs inverter in the system with 1pcs meter.We need to setup 1pcs inverter as the master and others setup as slaves.

7.3 Notes while using zero export func�on For your safety and the opera�on of limiter func�on of the inverter, we put forward the following sugges�ons and precau�ons: Safety Hint: Under zero export mode we strongly recommend that the two PV arrays are formed by the same number of PV panels of the same size, which will make the inverter more responsive to limit the power.
