A1-Hybrid series inverter is designed and certified to meet stringent UL1741/IEEE
1547 and ANSI/IEEE 62.41/62.42 lighting and surge requirements.
However, every PV installation is unique. Thus, additional external UL/NEC AC and
DC surge protection and solid grounding practices are recommended.
Battery Safety Instructions
►
SolaX A1-Hybrid Series inverter should be coupled with a high voltage battery.
The battery must comply with UL 1973 and must be intrinsically safe.
For the specific parameters such as battery type, nominal voltage and nominal
capacity etc., please refer to Section 4.3.
As accumulator batteries may contain potential electric shock and short-circuit
current dangers, to avoid accidents that might be thus resulted, the following
warnings should be observed during battery replacement:
1: Do not wear watches, rings or similar metallic items.
2: Use insulated tools.
3: Put on rubber shoes and gloves.
4: Do not place metallic tools and similar metallic parts on the batteries.
5: Switch off load connected to the batteries before dismantling battery
connection terminals.
6: Only personnel with proper expertise should carry out the maintenance of
accumulator batteries.

2.2 Explanation of Symbols
This section gives an explanation of all the symbols shown on the inverter and on
the type label.
CAUTION! Risk of electric shock from energy stored in capacitor. Never operate
on the inverter couplers, the MAINS cables, Battery cables, nor PV cables when
power is applied. After switching off the PV , battery and Mains, always wait for
5minutes to let the intermediate circuit capacitors discharge before unpluging
DC, battery plug and MAINS couplers.
When accessing the internal circuit of the inverter, it is very important to wait 5
minutes before operating the power circuit or demounting the electrolyte
capacitors inside the device. Do not open the device beforehand since the
capacitors require time to sufficiently discharge!
Measure the voltage between terminals UDC+ and UDC- with a multi-meter
(impedance at least 1Mohm) to ensure that the device is discharged before
beginning work (35VDC) inside the device.

IntroductionIntroduction
3 Introduction
3.1 Basic features
A1-Hybrid Series is a high-quality inverter which can convert solar energy to AC
power, convert AC power to DC power, and store DC power into a battery bank.
The inverter can be used to optimize self consumption, store in the battery for
future use or feed into public grid. Work mode depends on PV energy and the
user’s preference.
It can be used to power critical loads during a grid outage by using a battery, also
with the possibility of using power generated from PV arrays, and other string
inverters.

3.2 Work Modes
Work mode: Self-use (without PV Power)
When no PV supplied, the battery bank will
discharge for local loads first, and the grid will
supply power when the battery capacity is not
enough.
EPS Mode
When there is a grid outage, the ESS will supply
power from the PV and/or battery to supply
critical loads. (Battery is necessary in EPS
mode.)
A1-Hybrid inverter provides multiple work modes based on different
requirements. Some basic work modes of A1-Hybrid are shown as below.
Work mode: Feed in Priority
Priority: load > grid > battery
This mode applies to regions with feed-in tariffs
and export control.
Work mode: Back up mode
Priority: battery > load > grid
This mode applies to regions with frequent
power outages. This work mode will ensure the
battery maintains a minimum capacity fully
charged for when there is a grid outage.
In this mode work the battery will be charged
at the set time and will never discharge when
the grid is on. You can also choose whether to
charge or not from the grid or not.
Work mode: Self-use (with PV Power)
Priority: load > battery > grid
This mode applies the area that has low feed-in
tariffs and high energy prices.
Work mode: Force time use
Priority: battery > load > grid (when charging)
Priority: load > battery > grid (when discharging)
For applications that have different electricity
prices depending on the day, time and seasons.
The power generated from PV will be used to
supply the local loads firstly, then to charge the
battery bank. The redundant power will export
to the public grid.
The charging and discharging time can be set
flexibly, and it also allows to choose whether
charge from the grid or not.

6.4 Load connection & Auto-transformer connection
The A1-Hybrid Series inverter has on-grid and off-grid functionality. The inverter
will deliver output power through Grid port and Load port when the grid is on,
and it will deliver output power through Load port when grid is down.
Warning!
Note that the Load port can deliver output power only when an
auto-transformer is connected with the inverter functions property.
Warning!
Note the power rating of back-up Loads connected on the Load
port can not exceed the Load power rating.
Selecting appropriate Back-up loads
Before the system installation, define which loads will be critical during an outage,
and then connect them to the load port. When there is an outage, only these
back-up loads can be powered for essential usage. Examples of critical back-up
loads include: lights, electrical outlets, and a refrigerator.
The back-up load power rating must be within the Load port power rating,
otherwise the inverter will shut down with an “ overload” warning.
For the nonlinear load, make sure the inrush power is within the
Load output power range.
