Service Tip: Setting up Sunny Boy Storage to control export of SMA PV inverters

Service Tip Setting up Sunny Boy Storage to control export of SMA PV inverters

AC-coupled battery storage allows any new or existing PV system to flexibly add battery storage. The new Sunny Boy Storage is the simplest solution for adding battery storage to PV systems using new high voltage batteries such as the LG Chem RESU10U. However when adding battery storage to a PV system, grid operators may place additional requirements on the system such as limiting the export of energy from both the battery and PV inverters to the grid. With its smart capabilities, the Sunny Boy Storage is able to limit export of energy to the grid not only for itself, but also for up to three SMA PV inverters.

Service Tip: Accessing inverter information from new generation SMA inverters using WiFi and the Web User Interface


For improved long term reliability in the field, new generation SMA inverters do not have a built-in display. Instead these inverters utilise WiFi with a built-in Web User Interface (WebUI) to turn any smart device into an inverter display, even when the inverter is not connected to the internet. Connecting to the inverter’s WebUI can allow access to real-time performance of the inverter, as well as event and error log information. Such information can be useful to an installer or home owner either during system commissioning, field operation, or troubleshooting if things ever go wrong.

Service Tip: How to change grid parameters for SMA inverters in Sunny Explorer


One of the most important steps during the commissioning process is connecting the inverter to the grid.  For the inverter to be suitable for the local grid, the correct country standards must be selected. However, in some areas, customized grid settings of the inverter need to be configured to meet the special requirements of the local utility grid. Wrong grid settings can cause inverters to frequently cut off or affect the stability of the local grid. SMA inverters have flexible grid settings which can easily be changed via Sunny Explorer. Your SMA inverter can easily meet the requirements from local grid providers and have a stable grid connection at the same time.
