8.0 – PV Module (DC) Connection
The SimpliPHI inverter has two MPPT inputs for different string lengths or orientations along with an
integrated Rapid Shutdown Transmitter. This RSD transmitter is compatible with AP Smart rapid shutdown
devices which can be mounted to the back of each solar module (sourced separately). This RSD transmitter in
the inverter must be connected to an approved, remotely accessible E-Stop device that is readily available to
emergency personnel.
Each of the MPPT inputs can handle a maximum combined STC Short Circuit Current (Isc) of 21A with a
minimum input voltage of 160VDC and a maximum of 550VDC per string at expected operating conditions.
Parallel strings of equal length can be combined per each MPPT input as long as they meet the minimum and
maximum requirements stated in this manual. Each series string length should not exceed Voc of 600VDC at
maximum expected operating conditions. Consult the solar module specification sheet for operating
parameters to determine proper string sizing.
NOTE 1: Please use breakers that are rated for 1000VDC/20A
NOTE 2: Overvoltage category of the PV input is II.
CAUTION!
BEFORE CONNECTING TO PV MODULES, PLEASE INSTALL SEPARATELY A
RAPID SHUTDOWN OR EMERGENCY POWER OFF BUTTON AND TIE IN TO THE AP
SMART MODULE RELAY IN THE INVERTER.
WARNING!
AND VIOLATE THE TERMS OF THE WARRANTY!! CHECK THE PV SYSTEM WIRING
CONFIGURATION BEFORE MAKING YOUR FINAL CONNECTIONS.
