System Grounding and Bonding:
In this product, the PV, AC, and battery circuits are
isolated from the enclosure. This product has been
evaluated, listed and identified by UL to meet the
requirements of 690.41 and 250.4(A) of the NEC.
o The PV system ground reference and protection
is provided internal to the SkyBox, in accordance with
NFPA 70 690.41(A)(6).
o The AC connections are not bonded to ground.
The usual location for a neutral-ground bond is
at the main AC service panel. Make sure to establish
a neutral-ground bond when installing
in an off-grid application.
o The battery connection is not bonded to ground.
Make sure to establish a negative-ground bond for
each battery system. An 8½" AWG #4 green wire is
included with the hardware kit for this purpose.
Equipment grounding is required by Section 250 of the
National Electric Code (ANSI/NFPA 70) and Canadian
Electrical Code (C22.1).
Overcurrent Protection
The battery disconnect device in the BOS does not
o
provide overcurrent protection. The installer must
provide protection for the battery circuit according to
the following parameters.

Maximum 175 Adc

Minimum 10 kA AIC
AC overcurrent protection is provided in the BOS.
o
CAUTION:
!
To reduce the risk of fire, connect only to a circuit provided
with a 60 amperes maximum branch-circuit protection in
accordance with the National Electric Code, ANSI/NFPA 70.
IMPORTANT:
Not intended for use with
life support equipment.

Mounting Bracket

Ensure the mounting surface is strong enough to handle
three times the unit weight. (See the Specifications section.)
Add plywood or other material as necessary to strengthen the surface.
A Locate this horizontal slat at about eye level for easier display viewing.
B Do not place the top of the mounting bracket more than 6' (183 cm) above
l l
the floor. This ensures that the SkyBox can be easily lifted onto the bracket.
Mark the placement of the bracket according to A and B, keeping in mind the
dimensions in the second drawing. These dimensions (see above*) show the SkyBox
overlap (beyond the bracket) as well as the vertical measurements with respect to A.
They also add the required minimum clearances of 6" (15.2 cm) to SkyBox top and sides.
(This clearance includes the requirements for SkyBoxes in parallel. See Commissioning.)
IMPORTANT:
No lower clearance is shown. In outdoor installations a 36" minimum clearance above the
ground or floor is required. The lower vertical measurement becomes 60.6" (153.9 cm) from A.
Included in Box:
o SkyBox literature o SkyBox labels
o Battery conductors o Remote temperature sensor
o Ground bond conductor o Hardware kit
WARNING: Burn Hazard
The heat sink (at the top rear of the product) may
reach temperatures greater than 70°C. Install this
product so that casual contact does not occur.
WARNING: Fire/Explosion Hazard
Do not place combustible or flammable materials
within 12 feet (3.7 m) of the equipment. This unit
employs mechanical relays and is not ignition-
protected. Fumes or spills from flammable materials
could be ignited by sparks.
WARNING: Personal Injury
Use safe lifting techniques and standard safety
equipment when working with this equipment.

IMPORTANT
This document is for use by qualified personnel familiar with photovoltaic

(PV) systems and maximum power point tracking (MPPT) technology as
well as basic inverter functionality. Users of this document should meet
all local and governmental code requirements for licensing and training
for the installation of electrical power systems with AC and DC voltage
up to 600 volts. This product is only serviceable by qualified personnel.
Clearance and access requirements may vary by location. A 36" (91.4 cm)

clear space in front of the system for access is recommended. Consult
local electric code to confirm clearance and access requirements for the
specific location. If this product is installed or used in a manner other than
specified, the protection it provides may be impaired.
Fuses are not to exceed maximum output rating.

When installed outdoors, use only UL514B-compliant wet location or

rain-tight conduit hubs for entry into the enclosure.
See Specifications for instructions on system grounding and bonding.
