Installation Instructions

Ventilation

Outdoor
The inverter is designed for outdoor installation. Following
the working clearances specified in Table 5, no additional
space is required for the inverter to achieve proper air-flow
ventilation.
Indoor
When installing indoors (e-house), plan for the inverter's
heat-rejection during daily operation:
Intake/exhaust air volume is 4500 cfm
●
Recommended room-air exchange rate
●
Rejected heat is up to 35 kW at full export power under
●
optimum operation and cooling.
1 kW = 3412 Btu/hr
●
1 Btu = 1,055.0559 Joules
●
Site Recommendations
Eaton recommends that for optimum performance, the front
of the inverter should be facing the South-East direction.
