Supported Batteries


Sunny Island

The Sunny Island supports lead-acid batteries of types FLA and VRLA as well as various lithium-ion batteries. It is important to observe the capacity:

  • Lead-acid batteries with a capacity of 100 Ah to 10000 Ah can be connected.

  • Lithium-ion batteries with a capacity of 50 Ah to 10000 Ah can be connected.

This corresponds to a maximum storage capacity of 480 kWh for a battery with 48 V and 10000 Ah.

A lithium-ion battery is especially suited for intermediate storage of PV energy due to its high cycle stability. The lithium-ion batteries must be compatible with the Sunny Island:

  • The battery must comply with the locally applicable standards and directives and must be intrinsically safe.

  • The Sunny Island must only be operated in connection with an intrinsically safe lithium-ion battery approved by SMA Solar Technology AG (see Technical Information “List of Approved Batteries” at www.SMA-Solar.com).

  • If no lithium-ion battery approved for the Sunny Island can be used, use a lead-acid battery.

Sunny Boy Storage

The Sunny Boy Storage must only be operated in connection with an intrinsically safe lithium-ion battery approved by SMA Solar Technology AG (see Technical Information "Approved batteries and battery communication connection" at www.SMA-Solar.com).

Sunny Tripower Smart Energy

The Sunny Tripower Smart Energy must only be operated in connection with an intrinsically safe lithium-ion battery approved by SMA Solar Technology AG (siehe Technical Information "Approved batteries and battery communication connection" at www.SMA-Solar.com).

Lithium-ion battery for Sunny Island, Sunny Boy Storage and Sunny Tripower Smart Energy

The battery management of lithium-ion batteries controls the operation of the battery. To enable battery management, the lithium-ion battery must be connected to the battery inverter or hybrid inverter via a data cable.

In the case of compatible lithium-ion batteries, SMA Solar Technology AG has only tested the interaction between the battery inverter and the battery management of the lithium-ion battery. For information on other technical properties of the batteries, please contact the respective manufacturer of the lithium-ion battery.
