Planning
Applications
The SmartRE is intended for grid-interactive applications using photovoltaic (PV) panels to harvest
solar energy and a battery bank to store the harvested energy. The SmartRE has AC input terminals
which connect it to the utility grid, and AC output terminals which connect it to a "critical load"
subpanel for backup power. Normally grid power is transferred from the input directly to the output,
to run the critical loads. When excess PV is available from the batteries, the SmartRE supports those
loads with the PV. When the PV exceeds the load requirements, the SmartRE sells that excess power
back through its input, to the utility grid. When the utility grid is not available, the SmartRE takes over
to run the critical loads with PV and energy stored in the battery bank.
SmartRE models include:
¾SRE-2500-120-NA – 2500 W, 120 Vac/60 Hz ¾SRE-3000-120/240-NA – 3000 W, 120/240 Vac/60 Hz
¾SRE-2500-120/240-NA – 2500 W, 120/240 Vac/60 Hz ¾SRE-5000--120/240-NA – 5000 W, 120/240 Vac/60 Hz
¾SRE-3000-120-NA – 3000 W, 120 Vac/60 Hz ¾SRE-6000-120/240-NA – 6000 W, 120/240 Vac/60 Hz
Figure 3 Typical Grid-Interactive Application
PV Array Planning

¾SmartRE enclosures can be arranged horizontally or
vertically depending on the installation space that
is available. The SmartRE can be wall-mounted,
platform mounted, or stacked.
¾Only two modules can be stacked in a vertical
arrangement. Sets of stacked modules can sit side-by-
side. Ensure the location can support all the weight of
multiple systems. Battery enclosures must be floor/pad
mounted only.
¾In areas where seismic activity is a concern, consult
local code for seismic safety requirements. Horizontal
arrangements may be preferred using the wall-mounting
brackets for stability.

Environmental
¾This unit is rated for 25°C (77°F). Exposure to extreme hot temperatures can affect the unit’s performance.
When used in an outdoor installation, use a shading structure to avoid direct exposure to sunlight.
¾The mounting surface should be level and able to support three (3) times the weight of the enclosure. This
may require additional support for wall-mounted installations.
Clearance and Access Requirements
WARNING: Fire/Explosion Hazard
Do not place combustible or flammable materials within 12 feet (3.7 m) of
the equipment. Fumes or spills from flammable materials could be ignited by
sparks created by sub-standard wiring conditions.
IMPORTANT:
Clearance and access requirements may vary by location. Consult local electric
code to confirm clearance and access requirements for the specific location.
Maintain a 36” (0.91cm) clear space in front of the enclosures for access. To restrict access, a 0.45” hole
is provided on the Front Cover and the Front Cover Locking Bracket to accommodate the installation
of a standard lock.

Conduit and Knockout Preparation
Knockouts are provided on the top and bottom of the enclosures, and on both sides of the enclosures.
Bushings are recommended to prevent damage to conductors from sharp edges along knockout
holes. The rectangular knockout panel on the side can be removed and used as a hand-hold to lift the
enclosures into place. Remove the knockouts from this panel while it is attached to the side of the
enclosure to prevent damaging or bending the panel when removing knockouts.
IMPORTANT:
For 3R compliance, use rain-tight conduit connectors.

3/8” (1 cm) holes (x4) in corners of the bottom of
the enclosures provide a place for either anchor
bolts or leveling feet (not provided).
