Intended Use

The Sunny Boy is a transformerless PV inverter with 2 MPP trackers, which convert the direct current
of the PV array into grid-compliant alternating current and feeds it into the utility grid.
The product is suitable for indoor and outdoor use.
The product must only be operated with PV modules and cables that have been recommended and
sold by the distributor. Do not connect any energy sources other than PV modules to the 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.
PV modules with a high capacity to ground may only be used if their coupling capacity does not
exceed 3.4 μF.
All components must remain within their permitted operating ranges and their installation
requirements at all times.
The product is exclusively approved for the Japanese market and must only be used in Japan.
