2 Safety
2.1 Intended Use
The Sunny Tripower Smart Energy is a transformerless hybrid inverter with 2 MPP trackers and a
battery connection that feeds the direct current of the PV array into the connected battery or
converts it to grid-compliant three-phase current and then feeds it into the utility grid. The
Sunny Tripower Smart Energy also converts the direct current supplied by the battery into grid-
compliant three-phase current. In a system with additional PV inverters, the
Sunny Tripower Smart Energy can convert the three-phase current generated by the PV inverters
into direct current and feed it into the battery.
The Sunny Tripower Smart Energy has a backup function. In the event of a power outage, the
Sunny Tripower Smart Energy can continue to supply selected circuits with power from the battery
or PV system.
The product is suitable for indoor and outdoor use.
The product must only be operated with PV modules of protection class II in accordance with
IEC 61730, application class A. The PV modules must be compatible with this product.
The product is not equipped with an integrated transformer and therefore has no galvanic isolation.
The product must not be operated with PV modules whose outputs are grounded. This can cause
the product to be destroyed. The product may be operated with PV modules whose frame is
grounded.
The product must only be operated in connection with an intrinsically safe lithium-ion battery
approved by SMA Solar Technology AG. An updated list of batteries approved by SMA Solar
Technology AG is available at www.SMA-Solar.com.
