2.1
Intended Use
The SMA Energy System is a storage system and optimizes self-consumption of PV energy and
lowers the energy obtained from the utility grid by the following measures:
• Intermediate storage of PV energy in the battery
• Data logging at the grid-connection point with the energy meter (Modbus RTU)
• Visualization of the consumption and generation data from your system in Sunny Portal
Impairment of system communication
The use of external, unapproved components can affect the system communication.
• Only use approved components in the system.
Grid feed-in and purchased energy (from the utility grid) are only recorded with the energy meter
(Modbus RTU). The energy meter (Modbus RTU) does not replace the energy meter of the electric
utility company.
Use SMA products only in accordance with the information provided in the enclosed
documentation and with the locally applicable laws, regulations, standards and directives. Any
other application may cause personal injury or property damage.

IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working.
DANGER
Danger of fatal electric shock due to non-compliance with the safety
instructions in the documents that are enclosed with each product.
This document supplements the documents that are enclosed with each product and does not
replace any locally applicable codes or standards.
• Read and observe all documents enclosed with the products.
If the AC connection of the inverter is disconnected and the battery is
switched off, there is no risk of electric arcs during installation or servicing.
If the AC circuit breakers of the inverters are switched off and secured against reconnection
and the battery or the load-break switch of the battery is turned off and secured against
reconnection, there is no danger of an electric arc during installation or servicing. Be aware
that, when using batteries from BYD, the individual battery modules do not have their own
disconnects. With BYD batteries, all modules are disconnected by means of the BCU's main
switch. The AC circuit breaker of the inverter must be installed in the distribution board.
