Installation Space Requirement (see Figure 3-4a, b, and c):
The distances between the inverters or the surrounding objects should meet
the following conditions:
(A) Minimum Height from the ground (12 Inches minimum):
a. MUST Prevent Water damage in flood prone areas.
b. SHOULD Allow for ease of fan replacement
c. MUST meet NEC 6’ – 7” maximum height to disconnect.
(B) Minimum height between air intake or air exhaust. 6-inches is the smallest
allowable distance.
a. The distance MUST be great enough to allow low impedance to
air flow.
b. The distance SHOULD allow easy fan replacement access.
(C) The NEC specifies the maximum allowable height for a disconnect MUST
be 6’ - 7” Maximum.
(D) The distance between side by side inverters SHOULD be greater than 18”.
a. This dimension depends on if the inverters are stacked and
staggered (Figure 3-4a) or not. The stacked and staggered
configuration does not require a baffle since the exhaust of the
lower unit is directed between the inverters above.
(E) The distance between side by side inverters SHOULD be greater than 12”
– except in case (D) above.
(F) (F1) This dimension will be determined primarily by the structural strength
required to support the inverters. There MUST be a vertical chimney for
the exhaust air of at least 50 square inches directly above and per inverter.
(F2) The clearance above the inverter chimney MUST be greater than 6”
per stacked inverter. The front and rear of this dimension MUST be open
to allow horizontal air-flow.
(G) (G1) In the case of a wire-way installed between the stacked inverter, the
clearances MUST meet (B) and (C) above. For a 10” wire-way this would
be 22” minimum. (G2) If no wire-way is installed, the minimum clearance
MUST be greater than 18”.
(H) In the staggered configurations, the vertical alignment MUST be as shown.
If inverters are stacked and meet (C), Baffles must be installed unless the
inverters are staggered per Figure 3-4a. This configuration also allows ease
of conduit routing without a wire-way.
