1 AQ-TRON® HYBRID Inverter Introduc�on
The AQ-TRON® HYBRID inverter is used in a PV system with bery storage.
The energy produced by the PV system will be opmized for maximum self-consumpon.
The AQ-TRON® HYBRID inverter can operate in auto or me-of-use (TOU) mode, charging/discharging the ery as
needed. In auto mode, the inverter charges the excess PV energy in the ry and discharges the ry to supply
power to the local load when the PV energy ient.
In case of power failure, the AQ-TRON® HYBRID inverter can operate in emergency power supply (EPS) mode. The AQ-
TRON® HYBRID inverter will use power from the PV panels and energy stored in the baery to power the crical load.

2 Safety regula�ons
Make sure you read and understand this manual before install AQ-TRON® HYBRID inverter strictly complies
with safety regin design and tesg. During installon and maintenance, users must comply with
local safety regmproper opern may cause electric shock or damage to equipment and property.
2.1 Safety regula�ons
Electrical installaon and maintenance must be performed by qualied electricians according to local
regulaons.
The AQ-TRON® HYBRID inverter must be installed only by qualied electricians, and only those with the
appropriate acon as required by local authories.
DO NOT place explosivemmable materials such as gasoline, kerosene, diesel, oil, wood paste,
on or rags near teries or the AQ-TRON® HYBRID Inverter.
First disconnect the AC conneen disconnect the connec betwry and PV (PV1&PV2),
then wait at least 5 minutes (discharge capacitors) before performing maintenance to avoid electric shock.
The inverter must be completely disconnected (BAT, PV & AC) during maintenance.
The inverter may become very hot during o. Turn  the inverter and wait for the inverter to
cool down before performing maintenance.
Keep children away from baies and AQ-TRON® HYBRID inverter.
It is NOT permi to open the front cover of the AQ-TRON® HYBRID inverter. This will void the product
warranty.
AQ-TRON® HYBRID inverter damaged due to improper install/operaNOT covered by the
product warranty.
2.2 Installa�on and maintenance Remarks
The ba more than 60% charged before delivery and must be protected from short circuits
during transportaon and install
The inverter/bies should be placed in a well-veed place. Do not place the inverter/baies in an
air or poorly veed room or cabinet. This can be very detrimental to the performance and life of the
system.
Keep the inverter/baies away from direct sunlight. Do not put AQ-TRON® HYBRID inverter/baeries close to
an ovene. It may cause y to leak even to explode.
The current capacity of DC cables (from baery to inverter) should be at least 90 A. Use short DC cables to
avoid high voltage drop and current loss.
Use a mulmeter to check baltage and polarity before turning on the bies. Make sure the
ons are correct according to this manual.
Use a mulmeter to check the PV voltage and polarity before turning on the PV isolator. Make sure the
ons are correct according to this manual.
If you want to store the eries without using them, they should be disconnected from the inverter and
stored in a cool, dry and venlated environment.
y maintenance operators must have the knowledge and technical skill for bery maintenance;

All bies connected in parallel must be of the same model and have the same rmware version. This is a
design issue that must be considered by the designer/installer, especially when replacing baies or
modifying an exisng energy storage system.
AQ-TRON® HYBRID inverter has no transformer, therefore the posive pole and the nve pole of the PV
generator are NOT grounded. Otherwise, this will cause inverter failure. In the PV system, all non current-
carrying metal parts (such as: PV module frame, PV rack, combiner box housing, inverter housing) should
be connected to ground.
Warning: follow the following rules when installing/maintaining the bery.
A. Ta your watch, ring and other metal objects.
B. Use only tools with insulated handles.
C. Wear rubber gloves and shoes.
D.
Do not place tools or metals above the bery.
E. Turn othe AQ-TRON® HYBRID invertereries before conneonnecng the ry
terminals.
F. The posive/nve poles of the baery must be isolated from ground.
2.3 Symbols on the inverter
On the inverter there are some symbols related to safety. Please read and understand the contents of the
symbols before installing the system.
This symbol indicates a hazardous situa that could result in injury if not avoided.
Risk of electric shock and wait at least 5 minr turning othe inverter.
Beware of high voltage and electric shock.
Beware of hot surfaces.

CT (current transformer) can measure the value and direc�on of alterna�ng current. Refer to Fig. 11 for the
proper connec�on of CTa.

4.5 Cri�cal load connec�on (EPS func�on )
Cri load: if the grid fails and the EPS funcn is enabled, the inverter operates in EPS (emergency power) mode and
uses the PV power and the energy stored in the ry to supply power to the crical load via the connecon port LOAD.
LOAD connecon port is for connecriloads only. The power r crical loads must be less than
3000VA. The connec procedure of LOAD port is the same as that of mains connec 14). The shape of the
AC voltage does not exhibit an exact sine wave, Ba Supplies is not responsible if certain connected devices do
not work due to an abnormal wave.
Change posi�ons
CAUTION
The changeover switch is necessary.
Make sure the changeover switch is in posion 0 while checking/repairing the cri
load.
When checking/repairing the AQ-TRON® HYBRID inverter, make sure that the
inverter switch is in posion 0 and that the AQ-TRON® HYBRID inverter is
disconnected from the grid.
Under normal condions: inverter is set to posion 1. AQ-TRON® HYBRID inverter can supply power to
crical load in case of power failure.

phase grid
5.1 Principle
The AQ-TRON® HYBRID inverter can also be used in a three-phase grid (both 3x400V and 3x240V). In this
case a CHINT three-phase meter is required, it replaces the mono-phase current transformer.
The AQ-TRON® HYBRID inverter then works with phase compensa�on: although it is connected to one phase, it
will try to bring the SOM of all currents of all phases to zero as much as possible.
5.2 Setup
1. Place the chint 3-phase energy meter DTSU666 (BAT/50798) between the loss current switch and the
general low voltage board. Connect the cables from the loss current switch to terminals 3/6/9/10.
From terminals 1/4/7/10, the cables leave to the ALSB. CAUTION! The current sense in the Chint
energy meter determines correct opera�on of the system.
