Intended Use
The SMA Commercial Storage Solution is an energy management system for commercial uses, e.g., increased self-consumption or peak shaving.
System requirements
With the product it is possible to feed the three-phase current directly into the low-voltage grid while complying with the locally applicable connection requirements. If the product is operated with a medium-voltage transformer, the low-voltage side must be configured in a star formation and the neutral point grounded.
The product must only be used as stationary equipment.
The product must not be used as an uninterruptible power supply.
Loads connected to the product must have an CE, RCM or UL identification label.
Communication cables, measuring lines, and control lines must always be laid separately from AC or DC lines to prevent interference due to electromagnetic coupling during data transmission and any resulting malfunctions.
No additional loads or components in the DC intermediate circuit may be connected between the battery and inverter. Any changes to the system configuration must be agreed with SMA Solar Technology AG.
All components must remain within their permitted operating ranges and their installation requirements at all times.
The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the grid operator.
The product is intended exclusively for use in industrial environments.
The product must not be exposed to corrosive atmospheres.
Battery inverter requirements
The Sunny Tripower Storage is an AC coupled battery inverter for parallel grid operation. The Sunny Tripower Storage converts the direct current supplied by a battery into grid-compliant three-phase current.
The inverter is intended for use in residential and industrial environments.
The inverter complies with DIN EN 55011 of class B, group 1 as well as IEC 61000-6-3 and IEC 61000-6-2.
The inverter is suitable for operation in coastal installation according to IEC 61701 in corrosivity category C3.
The inverter is suitable for indoor and outdoor use.
The AC connection of the inverter must be installed with an external four-pole fuse protection (all line conductors and neutral conductors).
The inverter is not equipped with an integrated transformer and therefore has no galvanic isolation. The inverter must not be operated with batteries whose outputs are grounded. This can destroy the inverter. The inverter may be operated with batteries whose enclosure is grounded.
The DC lines of the positive and negative pole must be shorter than 30 m. In systems with 1 battery cabinet only, the DC cabling between battery inverter and battery cabinet is secured at all poles through the battery management system in the battery cabinet. In systems with more than one battery cabinet, the DC cabling between the battery inverter and battery cabinet in the DC distributor must have all-pole fuse protection.
Battery requirements
SMA Commercial Storage is a lithium-ion battery. The battery components are designed in accordance with the state of the art and the product-specific standards.
The battery meets the requirements of IEC 61508 Parts 1 to 7 and complies with safety integrity level (SIL) 1.
The battery is designed for use at altitudes of up to 2000 m above mean sea level. Electrical safety cannot be guaranteed at altitudes above 2000 m.
The battery is suitable for indoor use only.
On flood plains, care must be taken to ensure that the battery is always installed in an elevated position and protected from contact with water.
In accordance with IEC 62619, the battery is certified to safety integrity level SIL 1, and must therefore be installed in a room with protection against fire. The locally applicable fire regulations must be observed.
Fire protection measures for battery operation must be implemented in coordination with the responsible construction supervision authority on-site, in accordance with the locally applicable standards, guidelines and laws. Specifications can be found in the national and regional building codes.
