Single System Installs (Whole-Home 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 (100A) or AC-Coupled system to the GEN terminal block
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 = 135lbs (61.24kg). Securely attach to the wall. Affix a mounting board to studs using 6-8 screws
E. Use 2-3 screws + washers (choose screw length and surface type) 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. Add two screws for the bottom mount
Integrating Batteries (Sol-Ark POWERED "OFF")
A. Connect batteries to Sol-Ark as shown in Fig. B below
B. Install included toroids (Part e. on pg. 4) on battery input cables, as shown in Fig. A to the right
C. Ensure the built-in battery disconnect is OFF while connecting batteries, or arcing may occur
D. The 15K reaches a max of 275A of battery charge/discharge if using both sets of battery
terminals. If using one set of terminals, the max battery charge/discharge is 160A. (see pg. 21)
Multi-System Installs
a. ALL paralleled systems MUST connect to the same large battery bank, each with its own
cables attached
b. Do NOT use separate battery banks for parallel systems
Positive to
Sol-Ark
Negative
to Sol-Ark
Sol-Ark 15K is a 48V system. Do NOT wire
the battery bank to any other nominal
voltage.
When using 12V batteries do not exceed
FOUR (4) batteries in series.
When using other battery chemistries, stay
within the voltage range: MIN 43V-MAX 63V

Do NOT stack more than 2
banks high
PCC batts are
stackable
Do NOT reverse
polarity of batteries!
Damage will occur!
