INSTALLATION
Plan a location for the Encharge batteries
The Encharge housing is IP55 and can be installed indoors or outdoors. The
terminal blocks accepts copper conductors of 2.5 - 10 mm2.
A ) Following local standards, choose a well-ventilated location where
the ambient temperature and humidity are within -15° C to 55°
C and 5% to 100% RH, non-condensing, preferably out of direct
sunlight. The optimum ambient temperature range for installation
location is 0º C to 30º C. Provide smoke alarms in the residence in
accordance with building, re and installation codes.
B ) Ensure that the mounting location can sustain the total weight
of the Encharge batteries and mounting bracket. Total weight
for the Encharge 3T, including the Encharge base unit, cover and
wall mount bracket, is 48.8 kgs. Total weight for the Encharge 10T,
including the three Encharge base units, cover, and wall mount
bracket, is 143.6 kgs.
*WARNING: The installer should install blocking between studs
to ensure that no single stud carries the entire weight load of the
Encharge batteries.
C ) Plan the mounting location to be at least 15 cm off the ground and
15 cm from the ceiling. Keep the Encharge away from falling or
moving objects, including motor vehicles.
*WARNING: If mounted in the path of a motor vehicle, we
recommend a mounting height that is 91 cm minimum above the
oor.
D ) Ensure that there are no pipes or electrical wires where you plan to drill.
E ) Plan to maintain at least 1 m of clearance in front of each Encharge.
Allow at least 15 cm clearance on top and bottom of the Encharge
so that the vents on the top and bottom of the units are not blocked
for air circulation.
F ) Consider the dimensions of the Encharge batteries, easy access,
height, and length of cable when selecting the location.
G ) Follow all local standards.
H) Up to two Encharge 10T (or six Encharge 3T) units can be daisy
chained on one circuit. For installations with more than this number
of units, there must be a separate load center, subpanel, or circuit
combiner with over current protection to combine the daisy chained
circuits. You must select proper conductors and AC breaker for
these circuits according to local codes, standards, and other
applicable requirements.
The subpanel could be a small, two circuit box with circuit breakers.
The circuit breakers in the box would have to be suitable for
back-feeding, per local grid connection regulations.
Select the right size subpanel and breakers based on the number of
Encharge units being installed.
To do this, you must purchase an off-the-shelf subpanel and install
as shown in the following image:
1Install the AC disconnect
Following all local codes and standards:
A ) Install an AC isolator that can break the maximum rated current of
the branch circuit under load. The AC isolator must be installed in
line-of-sight of Encharge, per local regulations.
B ) Each Encharge unit is suitable for use with up to 10 mm2wires on a
maximum 40 A branch circuit.If more than six Encharge 3T or two
Encharge 10T are installed, a separate subpanel must be installed
between the Encharge units and main panel to combine the Encharge
circuits together. All circuit breakers in the subpanel must be suitable
for back-feeding, per local grid connection regulations.
C ) Verify that AC voltage at the site is within range: single-phase L to N
voltage must measure between 184 and 253 VAC.
