Procedure for device configuration
Qualified person
This section describes the procedure of device configuration for a charging station.
It provides an overview of the steps, which must be performed in the prescribed sequence.
Settings at point of interconnection | Explanation | See | |
|---|---|---|---|
Nominal grid voltage | Nominal value of the grid (e.g., 230 V) | ||
Maximum unbalanced load | Unbalanced load limit per national regulations (e.g., 4.6 kW in Germany). This is important for regulating the operation of single-phase and two-phase charging vehicles and the boost function. | ||
Phase assignment | Assign line conductors in the same way as the Sunny Home Manager 2.0 or Energy Meter at the point of interconnection. Important for the integrated unbalanced load regulation function. | ||
Operation with meter at point of interconnection | Explanation | See | |
|---|---|---|---|
Select the country data set | If you select a country data set which is not valid for your country and purpose, it can cause a disturbance in the PV system and lead to problems with the grid operator. When selecting the country data set, you must always observe the locally applicable standards and directives as well as the properties of the PV system (e.g. PV system size, point of interconnection). If you are not sure which standards and directives are valid for your country or purpose, contact the grid operator. | ||
Nominal current of the point of interconnection | Nominal value of the selective circuit protection at the point of interconnection or at the Sunny Home Manager. Important for control to ensure power outage protection. | ||
Active power limitation fallback value, control at the point of interconnection | Fallback charging power in case of loss of communication. | ||
Charging settings | Explanation | See | |
|---|---|---|---|
Nominal active power | Ability to limit the maximum charging power, e.g., to 11 kW. | ||
Minimum charging current | According to IEC 61851, min. 6 A. Can be adjusted for the specific vehicle, e.g., to 10 A. | ||
AC current limitation | Nominal value of the miniature circuit breaker for the separate electric circuit for the charging station. | ||
Disconnection after full charge | Relevant for the Sunny Home Manager to plan and reserve charging power. Select Yes if the available power is to be provided to the other optional loads after the charging process is completed. Select No if the charging station is the only controlled load, or if prior climate control is to be used. | ||
Standby for charging process to disconnection | Time until activation of “Disconnect after full charge.” The default value is set to 15 minutes. | ||
Lock the charging cable to the charging station | Permanent locking of the charging cable to the charging station. | ||
Setting the phase switching time | From firmware version 2.7.X.R, the phase switching time between 15 and 120 seconds can be configured via the parameter "Minimum switching time relay" (Chrg.MinSwTm). | ||
Settings in the delta IT system | Explanation | See | |
|---|---|---|---|
PE ground connection | For firmware version >2.5.xx.R, the parameter Ground connection monitoring is enabled by default. In a delta IT system, grounding monitoring cannot be carried out due to the physical characteristics of this system configuration. After startup, the SMA eCharger indicates event E-901: “PE connection missing.” Operation will not continue. Firmware version 2.5.29.R provides the option to disable ground connection monitoring. For the parameter Ground connection monitoring, select the value No. Then restart the SMA eCharger. | ||
Peak load shaving | Explanation | See | |
|---|---|---|---|
Warning: When peak load shaving is enabled, the functions for PV-optimized charging of the SMA eCharger are only available to a limited extent. The SMA eCharger may not be able to be switched on or start a charging process. Also, be aware of the effects of peak load shaving on other controllable loads in the energy management system. |
