4 Product Overview
SMA Solar Technology AG
Operating Manual 19HS-BM-3.28-10-BE-en-10
4.4 Interfaces and Functions
4.4.1 RJ45 connection
The battery is equipped with an RJ45 terminal as standard. The battery can communicate via cables with SMA
inverters via this RJ45 terminal (information on supported SMA products at www.SMA-Solar.com). For the
communicative connection of SunnyTripowerSmartEnergy, a pre-assembled communication cable is recommended
(see Technical Information "Approved Batteries and Information on Battery Communication Connection" of the
SUNNYTRIPOWERSMARTENERGY).
4.4.2 User Interface
The product is controlled by an inverter and is integrated into the user interface of the inverter.
4.4.3 Increased self-consumption
With increased self-consumption, the highest possible proportion of the power of a generator (e.g., a PV system) is
consumed at the place where it is generated. With increased self-consumption, power output and power consumption
at the point of interconnection are reduced.
The SMAHomeStorageSolution supports the increased self-consumption through intermediate storage of energy from
generators.
4.4.4 Black start
A black start is the startup of an energy supply system after a grid failure. With this black start, the energy supply
system uses internal energy reserves and is therefore independent of external energy sources.
The product supports a black start in conjunction with an inverter with battery-backup function and black start capacity.
If the energy supply from the utility grid and the PV system fails at the same time, a black start can be triggered
manually using the DC switch on the product.
4.5 LED signals of the battery modules
The LEDs indicate the operating state of the battery modules.
LED signal Explanation
The green LED is flashing
(2s on and 2s off)
Waiting for valid operating conditions
The conditions for charging and discharge mode are not yet met. As soon as the condi-
tions are met, the battery will start charging and discharging.
The green LED is glowing Charge and discharge mode
The battery charges or discharges in current-controlled operation.
The green LED is off No battery voltage
The red LED is glowing Error
Operation of the battery has been stopped. In addition, a distinct event message and
the corresponding event number will be displayed on the inverter user interface or in
the communication product (e.g., SMADataManage or SunnyHomeManager).
Red LED is flashing (0.25s
on, 0.25s off)
Alarm event regarding temperature or voltage
An alarm was triggered during operation. The battery keeps running, but the cause
should be checked.
Red LED is flashing (0.25s
on, 1.25s off)
Internal battery alarm
An alarm was triggered during operation. The battery keeps running, but the cause
should be checked.
