4. Decide Critical Backup Circuits

a. If using a 10-circuit switch: decide which 10 circuits will be on backup power continuously.

These circuits must use non-GFI breakers to work with the transfer switch. You can replace a

GFI breaker with a normal breaker, installing GFI outlets instead (or you can move GFI breaker

into 10-circuit SW). If applicable, low load circuits can be combined.

b. Important: Make sure to keep within inverter amperage limits (per inverter):

On Grid = 50A continuous

Off Grid = 33A continuous/83A peak

c. Verify each load circuit by measuring typical and max Amps with a clip-on Amp meter. Amps x

120V = Watts

d. If you have Arc-Fault / GFI breakers in your main panel we recommend that you install a

subpanel for your backup loads, not a multi-circuit transfer switch.

e. If using multiple 12K units in parallel consider powering the main breaker panel directly as

shown on page 15. (Example: 3 systems will have a total of 150A of pass through)

IF PROGRAMMED TO SMART LOAD

DO NOT CONNECT GENERATOR TO GEN PORT

February 3, 2020 5

5. Mount Multi-Circuit Transfer Switch (Not valid for Arc-Fault/GFI breakers)

Important notes:

When the transfer switch is in the “Gen” position, this means the circuit is being powered by the Sol-Ark

(which can use Grid/Solar/Battery/Generator automatically).

When in the “Line” position, the transfer switch is being powered by the grid (Sol-Ark can be removed).

The transfer switch setup is complete once all the switches are set to “Gen”position.

The Sol-Ark will take care of the rest.

If you are not installing a transfer switch (Off Grid or have a 50A sub-load panel), you can wire the “Load”

output of the Sol-Ark 12K directly to a Main Lug breakers sub-panel rated for at least 50A.

Please refer to page 11 for complete wire diagram

Strain Reliefs must be used for all wires going in/out of the Sol-Ark 12K user area

Ground and Neutral must be wired as shown above, or damage can occur.

Conduit (or double insulated wire) must be used for the AC Wires going to and from the Sol-Ark.

DO NOT CONNECT THE GRID TO THE LOAD OUTPUT BREAKER

Step 1. Turn off main breaker

Step 2. Connect White/Neutral wire (6 AWG) to Neutral Bar

Step 3. Connect Green/Ground wire (8 AWG) to Ground Bar

Step 4. Remove load wire (12 AWG) from circuit breaker and

connect it to the black “A” wire (12 AWG) with a wire nut.

Step 5. Place red “A” wire (12 AWG) from the switch into

breaker.

Step 6. Repeat steps 4-5 for circuits A-J

Note: All AC wires should be 6 AWG (4 AWG OK)

6. Single System Installs: Install Double Pole 50A breaker in Main Panel for Grid In/Out

a. It is best practice to install at the opposite end of the bus bar from the main breaker (Usually

this is the bottom of the breaker panel as seen on page 5).

7. Multi System Installs: Line side tap recommended for grid connection point

a. Please see page 15 for an example diagram.

8. Mount Sol-Ark 12K

a. Find a suitable location for the system(s), keeping in mind the dimensions in Fig. 1 below.

b. System must be protected from moisture and extreme heat. (Do not mount outdoors or in

attic OR WARRANTY WILL BE VOID AND DAMAGE WILL LIKELY OCCUR)

c. The system weighs 74lbs (34kg), be sure to attach it securely to the wall. You may need to affix

a mounting board to your wall first using 6-8 screws into studs.

d. Then use 2-3 screws (appropriate in length and type for your mounting surface) to mount the

French Cleat to the board/wall (washers recommended).

e. Mount the Sol-Ark on the installed cleat making sure that it sits properly and is level.

f. Add 2 screws in bottom mounts.

9. Connect Batteries (Sol-Ark should be POWERED “OFF”)

a. Connect the batteries to the Sol-Ark 12K as shown in the diagrams Fig. B below:

b. Fig. A: Install included ferrites (part k. on pg. 3) on the battery input cables. Slide

the ferrite over the battery cables so that both cables are within the toroid (as

shown in Fig. A).

c. When connecting batteries make sure the built-in battery disconnect is in the off

position while the batteries are connected, or arcing will occur.

d. Multi-system installs:

i. All systems in parallel are connected to the same battery bank, with each

system having its own battery cables to connect to the same large battery

bank. Do not use separate battery banks for parallel systems.

Note: PCC batteries are stackable

WARNING! Do not stack more than 2 banks high!

Do NOT reverse

polarity of batteries!

Damage will occur!

Best Practice

Spacer

Recommended

Sol-Ark 12K is a 48V system. Do not wire the

battery bank to any other nominal voltage.

When using 12V batteries do not exceed 4

batteries in series. When using other

battery chemistries, stay within the voltage

range: Min 43V-Max 63V

12V Battery Wiring Examples

February 3, 2020 9

10. Solar Panel Install

1. Sol-Ark 12K has 2 separate pairs of solar panel inputs. (Dual MPPT)

3. Max PV input:

16,500W(+/- 5%) per system (8,250W per MPPT) PV = 500Voc Max

Max Isc input per MPPT: 33A (self-limiting to 20A @450Voc/300Vmp or 18A @ 500Voc/400Vmp)

Note: Damage will occur if PV Voc > 550V.

4. Connect the strings of solar panels to the system as shown on pages 9/10.

5. Parallel strings per MPPT must be the same voltage, PV1A/B must be the same voltage if both are used (see

Fig. E).

6. Panel frame grounding can be done to any ground in the home via 12AWG wire. Mounts usually bond

frames together, so only 1 ground wire is needed.

Note: When connecting more than 13,000W +/- 10% of PV to Sol-Ark 12K, it is recommended that a portion of

the array faces a different direction (Example: 2 strings west, 4 strings south). This increases the max total

energy produced per day.

Note: Max Panels in Series (Rule of Thumb, always verify the string characteristics are within spec):

60 Cell: 10 72 Cell: 9 96 Cell: 6

If more than 2 strings in parallel:

each string must be fused (In-Line)

PV input

Positive

Negative

February 3, 2020 10

If using Y-Connectors: (Running two strings in parallel, totaling 20A (self-limiting) Note: separate wires can be

used per string, and string minimum is 5 panels or 175V)
