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 8K 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 8K inverter is also possible, potentially rendering it inoperable.
High Life Risk Due to Fire or Electrocution ONLY qualified persons should install the Sol-Ark 8K
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 500Voc 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 8K user area.
MUST use conduit (or double insulated wire) for AC Wires entering/exiting Sol-Ark 8K user area.
ALL terminals/breakers, including battery, MPPT, and AC Terminal Block inputs, should only have one
conductor connecting to them.
