Safety Hint: Please don’t connect PV array posi�ve or nega�ve pole to the ground, it could cause serious damages to the inverter.
  • Page 15 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.
  • Page 16 d) Finally insert the DC connector into the posi�ve and nega�ve input of the inverter,shown as picture 5.6 Pic 5.6 DC input connec�on Warning: Sunlight shines on the panel will generate voltage, high voltage in series may cause danger to life. Therefore, before connec�ng the DC input line, the solar panel needs to be blocked by the opaque material and the DC switch should be 'OFF', otherwise, the high voltage of the inverter may lead to life- threatening condi�ons.
  • Page 17 Pic 5.7 AC input connec�on Warning: Be sure that AC power source is disconnected before a�emp�ng to wire it to the unit. 1. Before making Grid port connec�on, be sure to turn off AC baeaker or disconnector first. 2. Remove insula�on sleeve 10mm length, unscrew the bolts, insert the wires according to polari�es indicated on the terminal block and �ghten the terminal screws.
  • Page 18 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.

    When the frequency exceeds StopPT: 51.5Hz, the inverter output should stop (ie 0 W). When the frequency is lower than StopPT: 51.5 Hz, the inverter will linearly increase the power output with a gradient of 100% Pmax/Hz un�l it reaches StrtPT: 50.5 Hz. In the hysteresis mode, when the frequency is lower than StopPT: 51.5 Hz, the inverter will not increase the power output un�l it is lower than RecPT: 50.1 Hz.
