Page 6: The Solaredge Electricity Meter
Chapter 1: Introduction The SolarEdge Electricity Meter The SolarEdge meter enables measuring the power and energy of the photovoltaic (PV) system. The meter is used by the inverter for the following applications: Consumption monitoring Export limitation StorEdge Smart Energy Management on-grid applications The meter is built into an enclosure and requires two Current Transformers (CTs; available from SolarEdge). The SolarEdge inverter or the Control and Communication Gateway (CCG) reads the exported power from a meter installed at the grid connection point or reads the consumption from a meter installed at the load consumption point.

Page 7: Meter Connection Options
Meter Connection Options Meter Connection Options In a single inverter system, the meter is connected directly to the inverter. If your inverter has a built-in revenue grade meter (RGM; the inverter is referred to a revenue grade inverter), you can connect an external meter on the same bus as the RGM (available form SolarEdge). Figure 4: Single-inverter connection In a multiple inverter system, two options are available: The meter is connected to the RS485 port of one of the inverters. In this case, as the inverter's RS485 port is occupied by the meter, use an RS485 Expansion Kit (available from SolarEdge) or ZigBee communication between the inverters. The meter is connected to one of the RS485 ports of a CCG. The CCG’s second RS485 port can be used to create an RS485 bus for communication between the inverters. This option is illustrated in Figure 5. Figure 5: Multi-inverter connection with CCG and meter SolarEdge SolarEdge Electricity Meter Installation Guide MAN-01-00270-1.0... -

The switch, disconnect, or circuit breaker must be located near the meter and be easily o perated . Use circuit breakers or fuses rated for 20A or less. Use grouped circuit breakers when monitoring more than one line. The circuit breakers or fuses must protect the mains terminals labeled L1, L2, and L3. In the rare cases where neutral has overcurrent protection, the overcurrent protection device must interrupt both neutral and the ungrounded conductors simultaneously. The circuit protection / disconnect system must meet a ll national and local electrical codes. Installing and Connecting the Meter Mount the meter on a wall or pole using the supplied bracket. To mount the meter: 1. Install the bracket with the semi-circles facing down, as shown below. Verify that the bracket is firmly attached to the mounting surface. Figure 6: Mounting bracket SolarEdge-SolarEdge Electricity Meter Installation Guide MAN-01-00270-1.0... - Page 9 Use only knockouts located at the bottom, back and sides of the enclosure. Opening the top knockouts may damage the protection rating of the enclosure. Figure 8: Meter - rear view 5. Mount the meter: Attach the meter enclosure back brackets to the mounted bracket using the four supplied screws. Tighten the screws with a torque of 9 N*m / 6.6 lb*ft. To install the CTs: 1. Turn off AC power before clamping on current transformers. 2. Install the CTs around the conductor to be measured. Split-core CTs can be opened for installation around a conductor. A nylon cable tie may be secured around the CT to prevent accidental opening. 3. Install the CT with the arrow pointing to the grid for consumption or export measurement.

Page 25: Appendix E: External Lightning Protection Connection
Appendix E: External Lightning Protection Connection Appendix E: External Lightning Protection Connection Protection devices are most often installed from each data line to the local earth ground, and should be selected to begin conducting current at a voltage as close to the system's normal communication level as possible, but never lower. For RS485 communication lines, the selected voltage rating is typically 6-8 V. Transient suppressors should be installed as close as possible to the port that is being protected, and the user must provide an extremely low impedance connection to the local earth ground of the SolarEdge device. This ground connection is crucial for proper suppression device operation. The ground connection should be made using a heavy gauge wire and kept as short as possible. If the cable between the SolarEdge device and the protection device must be longer than 1m/ 3.3 ft., a copper strap or a braided cable intended for grounding purposes must be used for the protection device to be effective. In addition to the high frequency nature of transients, extremely high current may flow. A protective device with surge discharge ratings of In: 10kA 8/20μs and Imax: 20kA 8/20μs is recommended. Various lightning protection devices are available for RS485 communication lines. The diagram below shows a connection example using the ISKRA ZAŠČITE VM-RS 485 data protocol protection device. A detailed datasheet can be found at: http://iskrazascite.si/uploads/datasheet/1396000869.pdf.
