Important Safety Instructions This manual contains important instructions to follow during installation and maintenance of the Photovoltaic Grid-connected Inverter(Microinverter).To reduce the risk of electrical shock and ensure the safe installation and operation of the Microinverter, the following symbols appear throughout this document to indicate dangerous conditions and important safety instructions.
but maintain the protective earthing conductor in the branch circuit breaker connect to the inverter ,then disconnect the DC inputs. In any circumstance, do not connect DC input when AC connector is unplugged. Please install isolation switching devices on the AC side of the inverter. Radio Interference Statement CE EMC Compliance:The equipment can comply with CE EMC, which are designed to protect against harmful interference in a residential installation.
CE mark is attached to the solar inverter to verify that the unit follows the provisions of the European Low Voltage and EMC Directives. Refer to the operating instructions. Person adequately advised or supervised by an electrically skilled person to enable him or her to perceive risks and to avoid hazards which electricity can create.

Microinverter System Installation A PV system using Microinverters is simple to install. Each Microinverter easily mounts on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect from the PV module directly to the Microinverter, eliminating the risk of high DC voltage.Installation MUST comply with local regulations and technical rules.
Installation Procedures a. Install an appropriate junction box at a suitable location on the PV racking system (typically at the end of a branch of modules). b. Connect the open wire end of the AC cable into the junction box using an appropriate gland or strain relief fitting.

WARNING: Prior to installing any of the microinverters, verify that the utility voltage at the point of common connection matches the voltage rating on microinverter label. WARNING: Do not place the inverters (including DC and AC connectors) where exposed to the sun, rain or snow, even gap between modules.Allow a minimum of 3/4 (1.5cm.) between the roof and the bottom of the Microinverter to allow proper air flow.
NOTE:When plugging in the DC cables, if AC already available,the Microinverter should immediately blink red light and will start work within the setting time (default 60 seconds). If AC is not available,the red light will blink 3 times quickly and repeat after one second until AC is connected.
3. The units should start blinking red one minutes after turning on the AC circuit breaker. Then blue led blinking. This means they are producing power normally, the faster blinking of the blue led means more power generated. 4. Configure the internal wifi module according to its user manual. 5.
GFDI Error A four time red LED indicates the Microinverter has detected a Ground Fault Detector Interrupter (GFDI) error in the PV system. Unless the GFDI error has been cleared, the LED will remain four times blinking. Other Faults All other faults can be reported to the website and APP. WARNING: Never disconnect the DC wire connectors under load.

2. Diagnosing from the network: a. No-Data-Display: The website and APP don't display any data.Check the network configuration. b. Only display microinverter is online but no data.This maybe because server is updating. To troubleshoot a non-operating Microinverter, Follow the steps below in order: 1.
Replacement Follow the procedure to replace a failed Microinverter A. Disconnect the Microinverter from the PV Module, in the order shown below: 1. Disconnect the AC by turning off the branch circuit breaker. 2. Disconnect the AC connector of the microinverter. 3.
