Warning Symbols
This symbol indicates information that, if ignored, could result in minor injury or
damage to the equipment.
This symbol indicates information that, if ignored, could result in serious injury,
damage to the equipment, or death.
This symbol indicates information that is important but not hazard-related.
Warnings
Read this entire document before installing or using the Sol-Ark 30K-3P-208V Inverter. Failure to
follow the instructions or warnings in this document can result in electrical shock, serious injury, or
death. Damage to the Sol-Ark Inverter is also possible, potentially rendering it inoperable.
High Life Risk Due to Fire or Electrocution –ONLY qualified personnel should install the Sol-Ark 30K-
3P-208V 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.
We recommend grounding the frames outside of the Sol-Ark circuit.
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 turn off the battery breaker if any current flows in or out of the battery.
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 30K-3P-208V user area.
MUST use conduit (or double insulated wire) for AC Wires entering/exiting Sol-Ark 30K-3P-208V user
area.
ALL terminals/breakers, including battery, MPPT, and AC Terminal Block inputs, should only have
one conductor connecting to them.

Deciding the Site’s Backup Circuits
A. Ensure you keep the Inverter within its amperage limits
•ON-Grid = 200A passthrough (160A software limitation)
•OFF-Grid = 30kW = 83.4A Continuous | 45kVA = 125A Peak (10s)
B. Verify each load circuit by measuring typical and max Amps with a clip-on Amp meter. Amps x 120V = Watts
C. Install a subpanel for backup loads if there is a chance of exceeding any amperage limits while powering the
entire site off-grid; failure to do so will result in an outage and potential damage to the Inverter
D. If you have Arc-Fault / GFI breakers, DO NOT use a multi-circuit transfer switch.

Single System Installations (Small Commercial Backup)
A. Use the output from 200A Fused Disconnect (from the grid) for the Grid input connection to the Sol-Ark
B. Connect the Load output from the Sol-Ark directly to the Main Service Panel (at least 2/0 AWG)
C. Connect a Generator (150A @ 120V x3) or AC-Coupled system to the GEN terminal blocks
Mounting the Sol-Ark
A. Keeping in mind Sol-Ark's dimensions, find a suitable location for the system(s)
B. NEMA 3R rating for Outdoor installations
C. PROTECT the LCD screen from excessive UV exposure
D. System weight = 172 lbs (78kg). Securely attach to the wall. You may affix a mounting
board to studs using 6-8 long wood screws
E. Use the four (4) bolts + washers provided to mount the French Cleat to the board/wall
F. Mount Sol-Ark on the installed French Cleat / Ensure Sol-Ark is level and sits properly
G. Secure with the six (6) small screws (from 9 provided) for both sides of the French Cleat
Integrating Batteries (Sol-Ark POWERED "OFF")
A. Connect batteries to Sol-Ark as shown below
B. Ensure the external battery disconnect is OFF while connecting batteries, or arcing may occur
C. The 30K-3P reaches a maximum of 100A battery charge/discharge when using both battery terminals. When
using one set of terminals, the max battery charge/discharge is 50A
Multi-System Installs*
Please contact Sol-Ark technical support for parallel operation details.
Sol-Ark 30K-3P-208V is a High Voltage
Battery system. Do NOT wire the battery
bank to any other nominal voltage.
When using 48V batteries, do not exceed
eight (8) batteries in series.
Stay within the voltage range:
MIN 160V-MAX 500V
Do NOT reverse
polarity of batteries!
Damage will occur!
Do NOT pull actuation levers more than 45 degrees
away from vertical when installing the batt cables
