Introduction Introduction SolarEdge’s StorEdge Solution can be used for various applications that enable energy independence for system owners, by utilizing a battery to store power and supply power as needed. The StorEdge Solution is based on and managed by the StorEdge Inverter with Backup (referred to as “StorEdge inverter” or “inverter” throughout the document) for both PV and battery management, and is compatible with the Tesla Powerwall Battery.
Introduction Backup Power Only Use stored energy for backup power only. The StorEdge inverter monitors the grid, and when it is down it automatically switches to backup mode, disconnecting from the grid and supplying power to backed-up loads. In cases where battery charging from the grid is permitted, this mode can be used without PV modules. Figure 2: Backup power only Smart Energy Management Only Use stored energy for smart energy management applications (detailed below).
Introduction In addition to these three modes, the StorEdge inverter can be used without a battery as a PV inverter with no StorEdge applications. NOTE For configuring the inverter when not using any StorEdge applications, refer to Appendix E - StorEdge Inverter without a Battery. NOTE The StorEdge inverter requires CPU version 3.18xx and above. If an upgrade is required contact SolarEdge support for an upgrade file and instructions. All modes can be used together with the export limitation application.
Backup Power with Smart Energy Management - System Configurations The next chapters describe each of these configurations for each of the three modes described above, and the required system setup via the inverter LCD and internal buttons and via the monitoring portal (where applicable). Backup Power with Smart Energy Management - System Configurations, page 5. Backup Power Only - System Configurations, page 18. Smart Energy Management Only - System Configurations, page 27.
Backup Power with Smart Energy Management - System Configurations For configurations with more than one SolarEdge inverter, the inverters are connected to each other with RS485, with one inverter configured as the master and connected to the SolarEdge monitoring server. An RS485 Expansion Kit is installed in the inverter for connection of the meter on a second RS485 bus.
Backup Power with Smart Energy Management - System Configurations The following diagram illustrates the connection of the system components when using two batteries. In this case, an external fused combiner box is needed. For enlarged segments of this diagram, refer to Appendix D – Detailed System Connection.
Backup Power with Smart Energy Management - System Configurations Basic Configuration This configuration is based on one of each of the StorEdge components and is suitable for most residential systems.
Backup Power with Smart Energy Management - System Configurations 5 Check the Communication status screen and verify that the battery and the meter are properly connected and configured: Prot – Displays how many devices are communicating with the inverter on the RS485-1 bus. ## – Displays how many devices are configured to communicate with the inverter on the RS485-1 bus. 6 If Dev is not MLT, the system is not pre-configured and requires full configuration. Proceed with step 9 below.
Backup Power with Smart Energy Management - System Configurations 2 To set a minimum battery charge level, so that the battery will always have energy stored in case backup power is needed, do the following: Select Power Control Energy Manager Storage Control. The following is displayed: 3 Select Backup RSVD and set the required level as percentage of the battery capacity. Set %PV according to user requirement.
Backup Power with Smart Energy Management - System Configurations 2 Select AC Charge Enable. 3 Select AC Charge Lim Limit Type and set one of the limits: 4 Set %PV to enter a limit as a percentage of year-to-date energy production. 5 Set kWh to enter a fixed annual energy limit. ► To verify communication: After connecting and configuring a communication option, perform the following steps to check that the connection to the monitoring server has been successfully established.
Backup Power with Smart Energy Management - System Configurations Large Residential PV Systems For residential sites with large PV systems, a StorEdge inverter and a SolarEdge single phase inverter may be installed together.

Proceed with step 10 below. 9 If ## = 01 and Prot = 01 – the battery is configured and communicating properly. Skip steps 10 to 13 below and proceed with set up backup power only as described below. 10 Select Communication RS485-1 Conf Device Type Multi-devices. A list of devices is displayed.

NOTE The meter is used for Smart Energy Management and does not measure the non-SolarEdge inverter production.
Appendix A – Creating a Charge/Discharge Profile Appendix A – Creating a Charge/Discharge Profile A charge/discharge profile is created from a yearly calendar, repeated for 20 years as long as no profile changes are made. The yearly calendar is divided into segments, with one of seven charge/discharge modes assigned to each segment.
Appendix A – Creating a Charge/Discharge Profile 12 Optionally select the Exceptions tab. In this tab you can define dates that should have a specific daily profile instead of the profile defined for the relevant period. For example, if you defined a weekly profile for a period from Dec. 15 to Jan.
Appendix B - System Behavior Example Appendix B - System Behavior Example In this example the StorEdge system uses maximize self-consumption mode with zero export limit. The inverter is connected to L1 and L2 in a split phase home. It supplies loads connected to L1 and to L2 load and exports excess PV power to the grid. The produced PV power is 2kW, and there is 2kW load on L1 and a 1kW load on L2. The StorEdge system supplies 3kW to the loads – including 1kW from the battery - and exports 0kW to the grid.
Appendix C – Verifying StorEdge Functionality Appendix C – Verifying StorEdge Functionality After system installation and configuration is completed, verify that the system is properly operating: ► To verify the meter: 1 Make sure other power sources (e.g. non-SolarEdge PV inverter) are not producing power. 2 Verify the AC is ON. 3 Check the meter (installed in export or consumption position, CT arrows point to the grid): 4 Turn the inverter ON/OFF switch to OFF.
