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 power point search status;
4. Green light is on—-MPPTMaximum power point locked state;
5. The green light turns red—-a.Island protection; b. Frequency protection; c. AC over/under-voltage protection;
6. 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 um power point search)→ The green light is on, (MPPT lock).

Kaideng WVC series micro-inverter installation guide

To properly install and use Kayden Energy WVC series micro inverters, please read and follow this guide and all warnings and instructions in Kay Energy WVC micro inverters. The “Installation and Operation Manual” can be downloaded from the official website of Kaden Energy: www.kaidengdg.com.Safety warnings are listed on the back of this guide. All models of WVC Series Micro inverter listed in this guide have a ground wire in the AC cable, no additional ground electrode is required(EGC), there are three wires in-side the AC cable with equipment, which are Blown zero line N (Blue) ground wire / safety line G (Yellow & green). Each micro-inverter is equipped with an AC cable with a length of 3 4 2 meters. The current of each AC cable branch cannot be greater than 40A. For the number of connected branches of each branch, refer to the following installat-ion guide.
Important information: Kaideng Energy WVC series micro-inverters use IP65 waterproof rating. When installing, please try to install it in a place where there is no rain, nor in a place where the sun is exposed to ensure ventilation and heat dissipation.

Preparation before installation:

1. Please visit our company’s official website www.kaidengdg.com to download the kaideng-app.apk app to install on your Android phone, then open the app and register an account on it, and create a power station on the account to reverse the WVC
series. The inverter is monitored or controlled. For detailed operation, please refer to the instructions in the inverter monitoring section.

2. The device for data collection with the inverter communication is WiFi- MODEM, and the communication method between WiFi MODEM and inverter is long- distance wireless transmission (open field 1800 meters, air baud rate 00bps). Operating frequency range (433.4-473.0MHz Up to 100 communication channels) Maximum 100mW (20dBm) transmit power (8 levels of power can be set) Four working modes, suitable for different applications, please refer to the WiFi MODEM manual for details.

3. Please refer to the following list and compare the electrical parameters of the solar modules in the table to select the inverter model.

4. 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.

5. Check if you still have the following related equipment: AC junction box, tools: screwdriver, wire cutter, voltmeter, tor -que wrench, socket and wrench for installing hardware,

6. After the installation of the power station is completed, please install a ground wire on the photovoltaic support, install and use a 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.

7. 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.

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

8. Implement all national electrical codes (NEC), ANSI / NFPA 70 in accordance with all local electrical codes and all relevant regulations.

9. Please note that only qualified personnel can install and / or replace Kaideng micro-inverters.

10. Please do not try to repair 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 micro inverter will invalidate the warranty.

11. 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.

12. Please make sure that the installation operation is performed before the AC power is disconnected, and do not install the Kaideng micro-inverter with power on.

13. Please install Kayden micro inverter series products as shown in the following figure.
