4. Decide Critical Backup Circuits

a. 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:

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

IF PROGRAMMED TO SMART LOAD

DO NOT CONNECT GENERATOR TO GEN PORT

5. Mount Transfer Switch

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 8K 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 8K user area

Ground and Neutral must be wired as shown above, or damage will 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 (10 AWG) to Neutral Bar

Step 3. Connect Green/Ground wire (12 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)

Opt. Limiters

6. 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. Mount Sol-Ark 8K

a. Find a suitable location for the system, 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 75lbs (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.

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

a. Connect the batteries to the Sol-Ark 8K 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).

i. The toroid usually fits inside the user area of the Sol-Ark.

c. When connecting for 1st time, use included 100ohm resistor (part b. on pg. 3) to

pre-charge the inverter for 30s before connecting 6ft cable to Sol-Ark (see Fig. D).

i. Hold the resistor so that it contacts the free battery cable and the battery terminal,

completing the circuit (see below). This can be done with small clamps or by hand.

Note: PCC batteries are stackable

WARNING! Do not stack more than 2 banks high!

Do NOT reverse

polarity of batteries!

Damage will occur!

Use included resistor to charge

capacitors when connecting batteries for

the first time. Hold for 30 seconds.

Best Practice

Spacer

Recommended

Sol-Ark 8K 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 41V-Max 59V

9. Solar Panel Install

1. Sol-Ark 8K has 2 separate pairs of solar panel inputs.

(Dual MPPT)

2. Use the chart to the right to determine how many strings of

panels and how many panels per string can be installed. This chart

is only a guide, other panel types and configurations can be

compatible if within system specifications.

3. Max PV input:

11,000W(+/- 5%) per system (6,000W per MPPT) PV = 500Voc Max

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. Each pair of strings, PV1A/B and PV2A/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: Max Panels in Series:

60 Cell: 10 72 Cell: 9 96 Cell: 5

Fig. E: Suggested Solar Panel String Guide

(60 or 72 cell Panels, 305W/Panel or less)

60-72 Cell 280W-315W panels assumed for

this guide. Please check your panel datasheet

to confirm Voc rating!!

August 3, 2019 10

(If using Panel Stands)

If using Y-Connectors: (Running two strings in parallel, totaling 18A (self-limiting) Note: separate wires can be

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