ATS-S

User Manual

Introduction

The Auto-Transfer Switch Single Phase (ATS-S)controls the switching of the contactors to provide power to the EPS load in both grid-tied

and off-grid conditions. The ATS-S integrates a contactor to provide users with a simple connection. It is used with Growatt Hybrid inverter

and AC coupled inverter (single phase). Configured with ATS-S, when the power outage, ATS-S can automatically switch to Off-Grid state,

it can continue to supply power to the EPS load, the load can continue to run.

Opening step of ATS-S

Open the ATS-S

As shown above, please put the key into the Keyhole on the ATS-S

right, clockwise rotation of 90°, the lower end of the first lock up

gently move Open, remove the lock at the upper end of the buckle,

then you can open the cover, Step of locking the cover opposite to

the above.

Wiring Connection

There are two type wire connection diagram of ATS , show as below:-S

9.1 total wire diagram

As shown in chart 2.1, the input side ATS-S is connected with

EPS and GRID of SPH/SPA inverter, the output side is connected

with EPS LOAD, and the position in the system is shown in the

circle in the chart 2.1. EPS LOAD default connect with Grid

power, if Grid is lost, EPS LOAD will turn to EPS output of hybrid

inverter.

2.Use the diagonal plier to trip 15mm of insulation from one side of

the 10AWG wires(6pcs);

Use the diagonal plier to trip 15mm of insulation from two side of

the 10AWG wires (2pcs,If it is standard 2, you need 3pcs);

Use the diagonal plier to trip 10mm of insulation from two side of

the 12AWG wires(2pcs);

Use the diagonal plier to trip one side of GND wire about

7mm(3pcs).

Note:

1.These include 2pcs 10AWG wire (1pcs red, 1pcs black) for

shorting contactor ports 2 and 4, 6 and 8, Its length is about 60cm,

10 AWG N wire (for standard2)length is about 50cm.

Standard 1 is for general using, and standard 2 is for like Australia where Neutral line can't be switched. When connect with ATS S,

please check which standard is suit for you.

3.There are three types wire need to be machining, please check

ref to 9.1 wired diagram. The follow three type wire are show

as below:

9.5 EPS-wires Connection

Use the screwdriver to unscrew the nut with position numbers 2,

4, 6 and 8 in the contactor, and the red 10AWG short wire ends

were inserted into the contactor port 2 and 4, The Black 10AWG

short wire ends were inserted into the contactor port 6 and 8,

then insert EPS load-L wire and EPS load-N wire into the port of

contactor(2&6) through the cable nut and tighten them with

screwdriver. Use a screwdriver to lock the ground wire on the E-

wire copper bar.

Use the screwdriver to unscrew the nut with position numbers

R1 and R7 in the contactor, and then insert GRID-L wire and

GRID-N wire into the port of contactor(R1&R7) through the

cable nut and tighten them with screwdriver. Use a

screwdriver to lock the ground wire on the E-wire copper bar.

Note:

The following step is an example for Australian grid system

where neutral line can't be switched. (If you do not have this

requirement, ignore the following step)

9.7 Checking

P l e a s e m a k e s u r e t h a t al l w i r i n g i n t h e AT S S i s

tightened， check the connection diagram with section 9.1.

In the process of use, if the EPS load does not work when the

on-grid, please turn off the Hybird inverter, and then open the

ATS-S cover, check the GRID and EPS LOAD line is connected

properly.

If the load does not work when off-grid, please turn off the

inverter, and then open the ATS-S cover, check the control line,

the EPS wiring and the EPS LOAD wiring is normal.

Use the screwdriver to unscrew the nut with position numbers

3 and 5 in the contactor, and then insert EPS-L wire and EPS-

N wire into the port of contactor(3&5) through the cable nut

and tighten them with screwdriver. Use a screwdriver to lock

the ground wire on the E-wire copper bar.

Note：

Please prevent other wires from getting loose during

operation.

Use the screwdriver to unscrew the nut with position numbers 5

and 7 in the contactor, and then insert EPS-L wire and EPS-N

wire into the port of contactor(5&7) through the cable nut and

tighten them with screwdriver.

Please use the equipment within the scope of specification.

Excessive current or voltage may cause device damage

To avoid personal injury due to energy hazard, remove

wristwatches and jewelry when repairing. Use tools with

insulated handles.

Repair are to be performed only by qualified technical personal

authorized by Growatt.

After connecting the ATS S internal wire, close the cover, the

GRID and EPS end of the ATS-S are respectively connected

with the AC GRID and EPS output of SPH/SPA inverter, EPS

load end access load, run SPH / SPA inverter, load to normal

operation.

A-EPS-L wire

B-Control coil-L wire

C-EPS-N wire

D-Control coil-N wire

Use the screwdriver to unscrew the nut with position numbers

A1， 3, A2 and 5 in the contactor, Then the red 12AWG wire ends

are inserted into A1 and 3, both ends of the black 12AWG wire are

inserted into A2 and 5, and tighten the corresponding nut with a

screwdriver.
