Page 8 Closing the Sunny Boy Page Introduction Installation Guide before starting the installation. For safety reasons, it is rec- ommended that only qualified personnel install and operate this equipment.

Consult with a representative of the local utility company before designing and installing a PV system. Page 14 Sunny Boy. Section 7: Displays and Messages This section provides troubleshooting tips and procedures for resolving problems that may occur during installation and operation.

If it becomes necessary to return the Sunny Boy, use the original packaging in which it was delivered. For this reason, it is required that the inverter be mounted so that the rating label on the side of the inverter be visible. The Sunny Boy must be mounted so that there is at least eight inches of clearance around it. Set the bracket aside temporarily, and drill holes at the marks you made on the wall.

Page 27 5. Insert the screws through the holes in the wall-mounting bracket and into the holes you drilled in the wall. Tighten the screws until the bracket is held firmly against the wall see Figure Do not overtighten the screws. The teeth of the washers should face towards the wall in order to ensure proper grounding. They are required to adequately prevent insects entering the unit. Carefully verify that the Sunny Boy is firmly mounted in place.

Page 30 Mounting Mounting Procedure 6. When the Sunny Boy has been mounted correctly it should look like one of the examples in Figure Moisture trapped within the enclosure may cause corrosion and damage to the electronic components.

Page 34 The figure Figure below illustrates commonly used transformer types. Remember, when connecting the Sunny Boy to the utility, the phase relationship is not important, but the voltage must be compatible. Page 36 The Figure below illustrates the proper jumper settings when connecting to a Delta : V Stinger type transformer. Note the order in which inverters are connected to the phases. Note: The Photovoltaic System Grounding shall be installed per the requirements of sections Wiring from the AC disconnect switch to the Sunny Boy, follow the procedure on page et seq..

Page Opening The Sunny Boy 2. Remove the screw from the underside of the switch handle with the provided allen-key. Pull off the switch handle. Page Wiring The Ac Output The following diagrams show the potential losses in AC wires with respect to the cross-sectional area of the cable and the length of the cable. Use the following diagrams to determine the best wire size to use for your particular installation. Page 47 Verify that all connections are correctly wired and properly torqued.

Figure shows a simplified wiring diagram of a PV system. Page Dc Input Grounding 1 and change the jumper position 2 as shown in the following illustrations. See the online SMA string size calculator at www. Verify that the external DC disconnect is open in the DC disconnect enclosure. Page 56 9. Page 58 Figure DC Connection with positive grounding 1. Page Communication Wiring Piggy-Back modules that can be installed and connected either at the time the inverter is installed or at any time thereafter.

These modules are not included with the Sunny Boy. Please contact SMA America for information. Refer to the instructions included with the communication module for installation procedures.

For detailed information, please see the Tech Updates section of our web site at www. Page Communication Module RS bus. Page Closing The Sunny Boy 3. Check the seal on the inside of the cover to ensure it is undamaged and in the correct position. Carefully position the cover on the front of the Sunny Boy so that the four holes in the cover are aligned correctly with the four threaded holes in the case. The teeth of the washers should face towards the LID. While holding the cover in place, carefully insert the four Page Commissioning 2.

Connect the grid voltage to the Sunny Boy by switching on the main AC circuit breaker in the main utility panel. Page 66 AC disturbance, the inverter will wait 5 minutes after the AC power has been restored to reconnect. When servicing the inverter, always disconnect the DC first, then the AC.

Shown in Figure This allows the user to determine the operating mode of the inverter at a glance. Page 68 The inverter will not restart automatically after detecting a ground fault. The ground fault may also clear the GFDI fuse. Page Led Operation Indicators Occasionally, during inclement weather or low irradiation, the LEDs may all turn on at once and then go off again.

This indicates that the inverter is trying to initialize but the power available from the array is not sufficient for normal operation.

This is not a malfunction. Page 70 Note: If the inverter fails to connect to the utility grid 3 times in a row, it will wait 10 minutes before the next attempt. The SMA Inverter feature galvanic isolation and can be used with all types of solar crystalline panels as well as thin-film. The die-cast aluminum enclosure, with the OptiCool active temperature management system, guarantees the highest yields possible and a long service life, even under extreme conditions.

Compact design makes SMA Inverter ideal for residential use and the integrated DC disconnect makes installation more cost effective. Increased efficiency means better performance and shorter payback periods. With over , fielded units, Sunny Boy has become the benchmark for solar inverter performance and reliability throughout the world.

When required, this process is assisted by a temperature controlled fan. The built in meter of the SMA Inverter displays system status as well as the solar energy being produced by the power plant and other key information on the LCD screen. Several meter and software options are available from Blue Pacific Solar. These codes may vary from city to city and county to county.

All grid-tied SunnyBoy inverter solar installations should be permitted and inspected, where required, by the local inspection authority in the same manner as other equivalent electrical systems. One last thing.

It is always a good idea to contract with a local licensed electrician to at least do the final electrical connection of your SMA Inverter system from the AC disconnect to your home utility breaker box.

Some local permitting authorities require that a licensed electrician do all the wiring from the rack to the utility interconnect. If you need help with the permitting documents for your SMA Inverter project, we are here for you. Solar permit service add on is available at checkout.

Be aware that only qualified personnel should install or replace SunnyBoy inverter. Do not attempt to repair the SunnyBoy inverter as it contains no user-serviceable parts.

If it fails, please contact SMA. Tampering with the SunnyBoy inverter will void the warranty.
