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.
Important Safety Instructions 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. The equipment could radiate radio frequency energy and this might cause harmful interference to radio communications if not following the instructions when installing and using the equipment.
Important Safety Instructions Symbols replace words on the equipment, on a display, or in manuals Can be OEM Trademark. Caution, risk of electric shock. Caution, hot surface. Symbol for the marking of electrical and electronics devices according to Directive 2002/96/EC. Indicates that the device, accessories and the packaging must not be disposed as unsorted municipal waste and must be collected separately at the end of the usage.

Microinverter System Introduction This integrated system improves safety; maximizes solar energy harvest; increases system reliability, and simplifies solar system design, installation, maintenance, and management. Microinverters maximize PV energy production Each PV module has individual Maximum Peak Power Tracking (MPPT) controls, which ensures that the maximum power is exported to the utility grid regardless of the performance of the other PV modules in the array.

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 Step 1 - Install the AC branch circuit junction box 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.
Installation Procedures 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.
Installation Procedures Step 4 - Install a AC cable protective end cap at the end of AC cable Step 5 - Connect Microinverters to the PV Modules NOTE: When plugging in the DC cables, the Microinverter should immediately blink one quick red and three short green. This will happen as soon as the cables are plugged in and will show that the Microinverter is functioning correctly.
Microinverter system operating instructions To operate the microinverter PV system: 1. Turn ON the AC circuit breaker on each microinverter AC branch circuit. 2. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a one-minute waiting time. 3.
Troubleshooting Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly: Status Indications and Error Reporting Start up LED One minute after DC power is first applied to the microinverter,one short red blinks indicate a successful microinverter startup sequence,be equal or greater than two short red blinks after DC power is first applied to the microinverter indicate a failure during microinverter setup.
Troubleshooting Troubleshooting a non-operating Microinverter There are two possible overall areas of trouble: A. The Microinverter itself may be having problems. B. The Microinverter itself is working fine but it is having trouble communicating with the ECD. The items below refer to Microinverter issues, not communication issues (addressed in the ECD manual).
Replace a microinverter 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.
Technical Data WARNING: Be sure to verify the voltage and current specifications of your PV module match with those of the Microinverter. Please refer to the datasheet or user manual. WARNING: You must match the DC operating voltage range of the PV module with the allowable input voltage range of the Microinverter.
