Installation Manual
*The Sunny Central 500HE-US was evaluated by UL for compliance with UL 1741 at the inverter
terminals and with UL Recognized external transformer Model DLHX0724T07001, Manufactured by
J. Schneider. This transformer is rated for a voltage of 200 V L-L on the primary side and an impedance
less than or equal to 6%.
Efficiency
11.1 Measurement Accuracy
The Sunny Central is not equipped with a calibrated meter. The display values may deviate from the
actual values and must not be used as a basis for invoicing. The Sunny Central’s measured values are
required for the system management and to control the current to be fed to the grid.
