System Components

A

Sunny Tripower Storage X 30 (STPS30-20) / Sunny Tripower Storage X 50 (STPS50-20)

Battery inverter for parallel grid operation that converts the direct current supplied by a battery into grid-compliant three-phase current.

When used as System Manager, the battery inverter in conjunction with an energy meter (Energy Meter or Power Quality Analyser) can take over the closed-loop control at the point of interconnection and provide open or closed-loop control of subordinate devices. The System Manager also takes over system monitoring and communication to the Sunny Portal powered by ennexOS.

For Sunny Tripower Storage X 30: SMA Commercial Storage 30 (Storage-30-20)

For Sunny Tripower Storage X 50: SMA Commercial Storage 50 (Storage-50-20)

Battery cabinet with battery management system: The battery management system contains the necessary all-pole fuse protection for one battery cabinet.

SMA Commercial Storage Extension

Battery module

D

Temperature and humidity sensor

The supplied temperature and humidity sensor continuously records the ambient temperature and humidity in the installation room. The collection of this data is a prerequisite for any warranty claims.

The temperature and humidity sensor is included in the scope of delivery of the battery cabinet.

E

Switch

Optionally, communication between the battery and battery inverter can be conducted via this switch. This simplifies the connection of a service PC to the battery monitoring software BatMon, for example.

The switch is included in the scope of delivery of the battery cabinet.

F

Energy meter: SMA Commercial Energy Meter 600 A / SMA Commercial Energy Meter 200 A / Power Quality Analyser UMG 604 E

The energy meter determines electric measured values at the grid connection point and transmits the measured data to the System Manager.

G

Only in systems with more than one battery cabinet: DC distributor including circuit breaker as fuse protection for the battery system

The DC distributor allows up to four battery cabinets to be connected to a battery inverter. The DC distributor contains the necessary fuse protection for the battery if there is more than one battery cabinet.

H

Optional: SMA Data Manager M (EDMM-20)

Data logger for monitoring and controlling the system. In systems with more than ten devices, the SMA Data Manager performs the role of the System Manager.
