Installing the Conduit Box

INSTALLATION HAZARDS

  • Read the installation instructions in the HELIOS ESS Installation and Operation Manual (805-0090) prior to installing the conduit box.

  • The following instructions do not provide the level of detail available in the HELIOS ESS Installation and Operation Manual. Reference the manual when installing the batteries and the conduit box.

Failure to follow these instructions may result in injury.

  1. Prepare the conduit box. If installing multiple HELIOS ESS batteries with conduit boxes, plan on drilling holes on the sides for passing wires and cables between conduit boxes with batteries.
    The diagram below is an example of the possible hole positions and sizes.

Example Size and Location of Holes (Ø63.2 mm [2.488 in], Ø28.7 mm [1.13 in])

Depending on the installation plan, holes may not be required on both sides of a conduit box, or may not be required at all.

  1. On the top side of the conduit box, punch out the knockouts required for the two positive and two negative inverter cables and the CAN communication cable.

  2. Use a stud finder to locate the wall studs.
    Identify a location that optimizes usability and support for the inverter and battery. The battery’s Wall-Mount Bracket requires at least 4 bolts supported by wall studs.

  3. If the wall studs are not in ideal locations, consider adding appropriate structural supports to spread the weight of the 130 kg (286.6 lb) battery and the 62.5 kg (135 lb) inverter.

  4. Use the template provided with the Conduit Box (see ITEMS SHIPPED IN THE BOX) and mark the location of holes for the battery and inverter wall-mount brackets.

Drilling Template

  1. Verify the hole marks are level, at the correct height, and in an appropriate location against the wall.

  2. Drill the holes for screws of the Wall-Mount Brackets of the Sol-Ark 15K-2P-N Hybrid Inverter and HELIOS ESS battery.

  3. Secure the HELIOS ESS Wall-Mount Bracket to the wall using appropriate fasteners that can support the battery’s weight and are compatible with the material of the wall or studs.

  4. Attach the HELIOS ESS battery to the Wall-Mount Bracket. Refer to the HELIOS ESS Installation and Operation Manual (805-0090) for instructions.

  5. On the top of the HELIOS ESS battery, unscrew the four conduit box mounting screws.

  1. Place the HELIOS ESS Sol-Ark Conduit Box on top of the battery and affix to the battery with the mounting screws.

  2. Attach the Sol-Ark 15K-2P-N to the inverter Wall Mount Bracket. Refer to the inverter manufacturer’s documentation for installation instructions.
