NOTE A SolarEdge inverter may be installed in a site with a generator, however must not operate at the same time as the generator. Operating an inverter and a generator simultaneously will void the warranty. SolarEdge requires installing a physical or electronic interlock, which will prevent the generator and inverter from operating simultaneously.
Chapter 1: Introducing the SolarEdge Power Harvesting System Chapter 1: Introducing the SolarEdge Power Harvesting System The SolarEdge power harvesting solution maximizes the power output from any type of solar Photovoltaic (PV) installation while reducing the average cost per watt. The following sections describe each of the system’s components.
Inverter with Safety Switch Each power optimizer also transmits module performance data over the DC power line to the inverter. Two types of power optimizers are available: l Module Add-on power optimizer – connected to one or more modules l Smart modules - the power optimizer is embedded into a module Inverter with Safety Switch The inverter efficiently converts DC power from the modules into AC power that can be fed into the main AC service of the site and from there to the grid.
Chapter 1: Introducing the SolarEdge Power Harvesting System Installation Procedure The following is the procedure for installing and setting up a new SolarEdge site. Many of these also apply to modification of an existing site. 1. Connecting Power Optimizers in Strings, page 21. 2. Recording power optimizer serial numbers (optional), page 49. 3. Mounting the inverter, Page 28. 4. Connecting the strings and the AC to the Safety Switch, page 33. 5. Commissioning and activating the installation, page 41. 6.
Chapter 2: Installing the Power Optimisers Chapter 2: Installing the Power Optimisers Safety The following notes and warnings apply when installing the power optimizers. Some of the following may not be applicable to smart modules: WARNING! The metallic enclosure of the power optimizer must be grounded in accordance with the product's listing and local and national codes.
Chapter 2: Installing the Power Optimisers CAUTION! If you intend to mount the optimizers directly to the module or module frame, first consult the module manufacturer for guidance regarding the mounting location and the impact, if any, on module warranty. Drilling holes in the module frame should be done according to the module manufacturer instructions.
Installation Guidelines Installation Guidelines l l l l l l Frame-mounted power optimizers are mounted directly on the module frame , regardless of racking system (rail-less or with rails). For installation of frame-mounted power optimizers, refer to http://www.solaredge.com/sites/default/files/installing_ frame_mounted_power_optimizers.pdf. The steps in this chapter refer to module add-on power optimizers.
Chapter 2: Installing the Power Optimisers Figure 3: Power optimizer clearance l When installing modules in a confined space, for example, if installing Building-integrated photovoltaic (BIPV) modules, ventilation measures may be needed to ensure the power optimizers are not be exposed to temperatures outside their specifications. NOTE The images contained herein are for illustrative purposes only and may vary depending on product models. -Three Phase System Installation Guide MAN-01-00527-1.
Step 1: Mounting and Grounding the Power Optimizers Step 1: Mounting and Grounding the Power Optimizers For each of the power optimizers1: 1. Determine the power optimizer mounting location and use the power optimizer mounting brackets to attach the power optimizer to the support structure (See Figure 4). It is recommended to mount the power optimizer in a location protected from direct sunlight.
Chapter 2: Installing the Power Optimisers Figure 4: Power optimizer installation and grounding using a star washer l For mounting on rails with sliding nut fasteners: If the star washer cannot be used, use the SolarEdge grounding plate (purchased separately) between the railing and the flat side of the mounting bracket. Use mounting specific hardware as needed. Apply torque of 9.5 N*m / 7 lb*ft.
Step 2: Connecting a PV Module to a Power Optimiser 6. Record power optimizer serial numbers and locations, as described in Reporting and Monitoring Installation Data on page 49. Step 2: Connecting a PV Module to a Power Optimiser NOTE Images are for illustration purposes only. Refer to the label on the product to identify the plus and minus input and output connectors.
Chapter 2: Installing the Power Optimisers Step 3: Connecting Power Optimizers in Strings You can construct parallel strings of unequal length, that is, the number of power optimizers in each string does not have to be the same. The minimum and maximum string lengths are specified in the power optimizer datasheets. Refer to the Designer for string length verification. IMPORTANT SAFETY FEATURE For a compliant PV Rapid Shutdown System (PVRSS) installation, use no more than 30 optimizers per string. 1.
Step 4: Verifying Proper Power Optimiser Connection Step 4: Verifying Proper Power Optimiser Connection When a module is connected to a power optimizer, the power optimizer outputs a safe voltage of 1V (±0.1V). Therefore, the total string voltage should equal 1V times the number of power optimizers connected in series in the string. For example, if 10 power optimizers are connected in a string, then 10V should be produced. Make sure the PV modules are exposed to sunlight during this process.
Chapter 3: Installing the Inverter Chapter 3: Installing the Inverter Install the inverter either before or after the modules and power optimizers have been installed. NOTE l l Use only copper conductors rated for a minimum of 90°C/ 194°F. For the SE10KUS, SE20KUS, SE33.3KUS three phase inverters where opposite polarity DC conductors are routed in the same conduit, 1000V rated cables must be used.
Inverter Interfaces l ON/OFF/P Switch: Figure 10: ON/OFF/P switch o o o ON (1) - Turning this switch ON (after optimizer pairing) starts the operation of the power optimizers, enables power production and allows the inverter to begin exporting power to the utility grid. OFF (0) - Turning this switch OFF reduces the power optimizer voltage to a low safety voltage and inhibits exportation of power. When this switch is OFF, the control circuitry remains powered up.
