PVP250kW & PVP260kW Inverter
Installation & Operation Manual
3.5 Environmental Requirements
The unit may be installed either indoors or outdoors. If the installation of the inverter is
outdoors, all interconnect conduit and ttings must be rated NEMA 4 (same as inverter
rating) as required by the NEC. For hot locations a shade structure should be placed over
the unit in order to reduce thermal stress and extend the product’s life.
Inverter power output will be de-rated for ambient temperatures in excess of 50°C/122°F.
Clearances: Front = 3 feet, Rear = 2 inches, Sides = 12 or 36 inches, Top = 18 inches.
Cooling Air Requirements: The maximum cooling air ow rate is 2300 CFM. No external
intake or exhaust air ports in the building are required if volume needs are met.
The maximum heat rejection rate is 41,000 BTU/hr.
3.6 Grounding and Neutral Requirements
PV Array Frame Grounding
The inverter incorporates an integral GFDI device. The PV array safety ground (frame
ground) may be attached to the grounding busbar provided. The grounding busbar is
located below the DC sub panel in the front left of the inverter cabinet. The PV array is
grounded internally by means of the GFDI.
!
DANGER
Do not connect the PV negative or positive conductors to the ground busbars
provided. The PV array is grounded through the integral GFDI. Connecting
the PV array positive or negative conductors to ground at any other point in
the system would defeat the ground fault protection circuit.
!
DANGER
Ne branchez pas les conducteurs photovoltaïques positifs ou négatifs à la
barre omnibus de mise à la terre fournie. Les piles PV sont mises à la terre
grâce au GFDI intégral. Mettre les conducteurs positifs ou négatifs à la terre à
tout autre point du système ne permettrait pas au circuit de protection contre
les mises à la masse défectueuses de fonctionner normalement.
The inverter is shipped pre-congured with positive or negative PV array grounding
based on the preference provided at the time of order.
