Device and system description

Battery management for PIKO MP plus  

with connected battery 

The PIKO MP plus is not able to control a connected 
battery itself. In order to do this, the PIKO MP plus also 
needs the  KOSTAL Smart Energy Meter and a battery 
activation code, both of which can be obtained from our 
 KOSTAL Solar online shop. The  KOSTAL Smart Energy 
Meter then handles battery management and transmits 
control information to the PIKO MP plus for this purpose. 

Communication between 

 KOSTAL solar inverters and 

 KOSTAL Smart Energy Meter

The  KOSTAL Smart Energy Meter provides various 
interfaces for communication purposes. These establish 
a connection to other  KOSTAL solar inverters, sensors or 
the Internet. 

 

n

LAN 
LAN connects the  KOSTAL Smart Energy Meter to 
the local home network, via which it can then access 
other inverters or the Internet and Solar Portal. 

 

n

RS485/Modbus (RTU)  
Inverters or other devices approved by  KOSTAL Solar 
 Electric, via which information or control commands 
are communicated, are connected to the Modbus 
interface.
