Warning symbols
This symbol indicates information that, if ignored, could result in minor injury or
equipment damage.
This symbol indicates information that, if ignored, could cause serious injury,
equipment damage or death.
This symbol indicates relevant information that is not related to hazard situations.
Warnings
Read this entire document before installing or using the Sol-Ark 12K inverter. Failure to follow any of
the instructions or warnings in this document can result in electrical shock, serious injury, or death.
Damage to the 12K inverter is also possible, potentially rendering it inoperable.
High Life Risk Due to Fire or Electrocution ONLY qualified persons should install the Sol-Ark 12K
inverter.
The system must have Ground connections and Neutral connections. Ground MUST be bonded to
Neutral ONLY ONCE in the circuit.
Solar PV+/PV- are UNGROUNDED. Note, you may ground PV Racking/Mounts, but doing so directly to
the Sol-Ark will likely result in damage in the case of a direct lightning strike to the PV array.
DO NOT connect the grid to the Load Output Terminal Block.
DO NOT reverse the polarity of batteries. Damage WILL occur.
DO NOT exceed 800Voc on any MPPT on the Sol-Ark.
DO NOT use impact drivers to tighten any fasteners on the Sol-Ark.
MUST use Strain Reliefs ON ALL wires entering/exiting the Sol-Ark 12K user area.
MUST use conduit (or double insulated wire) for AC Wires entering/exiting Sol-Ark 12K user area.
ALL terminals/breakers, including battery, MPPT, and AC Terminal Block inputs, should only have one
conductor connecting to them.

Backup circuits
A. The sub panel powered by the LOAD terminal will be considered the critical loads panel.
B. You must keep the critical loads panel within the limitations of the unit:
•It must be sized to cover 12KW in loads.
Mounting the Sol-Ark
A. Considering the dimensions of the inverter, find a suitable location for the system(s), see Figure (1.1), there must
be at least 50cm of upper clearance for proper heat dissipation. Heat transfer is done from bottom to top at a rate
of 290W/hr.
B. NEMA 3R - IP65 enclosure, rated for outdoor installation (can be installed indoors) .
C. PROTECT LCD screen from direct exposure to UV light.
D. Mount the Sol-Ark on the installed French cleat / ensure Sol-Ark is level and sits properly (French cleat dimensions
can be seen on page 8).
