Description of the connector and cable core of the microinverter

Note: You can purchase a professionally customized AC bus with a T-type connector.
Use this AC bus as the AC bus for each branch. Connect it hand in hand to form a modular micro-inverter branch wiring system.

LED indicator function of micro-inverter

1. Red light is on—The micro-inverter is powered on, the red light is on, and the equipment is ready to work;
2. Red light flashes—-The micro-inverter is fully prepared and enters the delayed startup state;
3. Flashing green MPPTMaximum PowerPoint search status;
4. Greenlight is on— —MPPTMaximum PowerPoint locked state;
5. The green light turns red—-
   a.island protection;
   b. Frequency protection;
   c. AC over/under-voltage protection;
   d. DC voltage over and under-voltage protection;
   e. fault; f. software shutdown;

Normal working indicator flashing process:
Connect the micro-inverter to the AC and DC terminals, and then turn on the power — the red light will be on for 3 seconds — the red light will flash for 30 seconds — the green light will flash quickly (MPPT maxim urn PowerPoint search)— The green light is on, (MPPT lock).

Accessories of micro-inverter

Preparation before installation:

1. Please install Kayden micro inverter series products as shown in the following figure.
2. Please note that only qualified personnel can install and/or replace Kaideng micro-inverters.
3. Before installing or using Kaideng Micro Inverter, please read all instructions and technical instructions and the warning mark system and photovoltaic array on Kay Microinverter.
4.  When installing the inverter handshake cable, please plan that your AC branch circuit cannot exceed the current limit, so that the maximum number of micro-inverters in each branch can be reasonably allocated.
   Inverter model| Number of branches
   ---|---
   WVC-295| 30PCS
   WVC-300| 30PCS
   WVC-350| 25PCS
   WVC-600| 15PCS
   WVC-700| 12PCS
   WVC-1000| 10PCS
   WVC-1200| 8PCS
   WVC-1400| 6PCS
   WVC-1600| 5PCS
   WVC-2000| 5PCS
   WVC-2400| 3PCS
   WVC-2800| 3PCS

*Each region may be different. Please refer to local requirements to define the number of micro-inverters per branch in your area.

5. Implement all national electrical codes (NEC), ANSI / NFPA 70 in accordance with all local electrical codes and all relevant regulations.
6. Please do not try to repair the Kaideng micro-inverter. It does not contain user-serviceable parts. If it fails, please contact Kaideng customer service to obtain the ID number and start the replacement process. Tampering or opening the Kaideng microinverter will invalidate the warranty.
7. Please make sure that the installation operation is performed before the AC power is disconnected, and do not install the K -aiding micro-inverter with power on.
8. After the installation of the power station is completed, please install a ground wire on the photovoltaic support, install and use lightning protection, and/or surge suppress -ion equipment protection system in the AC junction box. It is very important to have a switch device that automatically protects against lightning strikes and surges.
9. In addition to Kaideng Energy’s WVC series micro-inverters, you must also purchase photovoltaic brackets / AC boxes / electrical cables and other related materials. The current of each channel of the WVC series micro-inverters at the branch of the installed circuit cannot exceed 40 Amp, if the rated current is exceeded, it may lead to an unsafe factor.
10. Check if you still have the following related equipment: AC junction box, tools: screwdriver, wire cutter, voltmeter, torque wrench, socket and wrench for installing hardware, etc.

Inverter installation steps

Step1: Install the inverter on the bracket of the photovoltaic panel with the screws provided with the machine, as shown in the fo -the following figure:

Step2: Connect the positive and negative poles of the DC connection MC4 plug on the photovoltaic board to the DC input terminal of the inverter, as shown below:

Step3: Open the waterproof cover of the AC output connector of the inverter and connect the AC cable to the AC waterproof plug. The connection method is as shown in the plug connection diagram:

Step 4: Connect the AC output cable to the AC main cable;
Step 5: Repeat steps 1 to 3, install and connect all inverters;
Step 6: Connect the AC main cable to the utility grid to start your green energy journey.

Note: Before installing WVC series microinverter products, please read this manual and pay attention to the installation details.
This manual contains important instructions that should be followed when installing and maintaining reduced the risk of electric shock and ensure safe installation and ope
-ration of Kaideng MicroInverters, Always follow the following safety symbols present in this document to indicate hazardous conditions and important safety Instructions.
