2 Introduction
2.1 Basic features
The inverter is a high-quality inverter which can convert solar energy to AC energy and store
energy into battery. The inverter can be used to optimize self consumption, store in the
battery for future use or feed-in to public grid. Work mode depends on PV energy and
user’s preference. It can provide power for emergency use during the grid lost by using the
energy from battery and inverter (generated from PV).

2.3 Work Modes
Inverter provides multiple work modes based on different requirements.
Work modes: Self-use (with PV Power)
Priority: load>battery>grid
This mode applies the area that has low feed-in tariff and high energy price.
The power generated from PV will be used to supply the local loads
firstly, then to charge the battery. The redundant power will export to
the public grid.
Work modes: Self-use (without PV Power)
When no PV supplied, battery will discharge for local loads firstly,
and grid will supply power when the battery capacity is not enough.
Work modes: Force time use
Priority: battery>load>grid (when charging)
Priority: load>battery>grid (when discharging) this mode applies the
area that has electricity price between peak and valley. User can use off-

6
peak electricity to charge the battery.
The charging and discharging time can be set flexibly, and it also
allows to choose whether charge from the grid or not.
Work modes: Feed in Priority
Priority: load>grid>battery
This mode applies the area that has high feed-intariff and export control.
The PV generated power will be used to supply the local loads firstly, then
export to the public grid. The redundant power will charge the battery.
Work modes: Back up mode
Priority: battery>load>grid
This mode applies the area that has frequentpower outages. And this
mode ensures the battery will has enough energy to supply when the
grid is off .
In this mode battery will be charging forcibly in the setting time and
will never be discharged when the grid is on, and it also allows
choose whether charge from the grid or not.
Back-up status
When the grid is off, system will supply emergency power from PV or
battery to supply the home loads. (Battery is necessary in BACK-UP
mode.)

5. Electrical Connection
5.1 PV connection
Hybrid can be connected in series with 4-strings PV modules for 10KVA, 12KVA, 15KVA.
Select PV modules with excellent function and reliable quality. Open-circuit voltage of
module arrays connected in series should be <Max. DC input voltage; operating voltage
should be conformed to MPPT voltage range.
Warning!
PV module voltage is very high, which already achieve dangerous voltage range,
please comply with electric safety rules when connecting.
Please do not make PV positive or negative ground!
Step 1:Connection Steps
1. Checking PV module.

1.1 Use multi meter to measure module array voltage.
1.2 Check the PV+ and PV- from the PV string combiner box correctly.
1.3 Please make sure the impedance between the positive pole and negative pole of PV
to earth should be MΩ level.
Step 2: Separating the PV connector.
1. Wiring.
1.1 Choose the 12 AWG wire to connect with the cold-pressed terminal.
1.2 Remove 12mm of insulation from the end of wire.
1.3 Insert the insulation into pin contact and use crimping plier to clamp it.
1.4 Insert pin contact through the cable nut to assemble into back of the male or female
plug. When you feel or heard a “click” sound the pin contact assembly is seated correctl.
1.5 Plug the PV conntector into the corresponding PV connector on inverter.
Note!
The following requirements of PV modules need to be applied for
each input area;
Please do not make PV positive or negative ground!
In order to save cable and reduce the DC loss, we suggest to install the
inverter near PV modules.
5.2 Grid Connection
Hybrid series inverter are designed for single phase grid. Voltage is 230V, frequency is 50Hz.
Other technical requests should comply with the requirement of the local public grid.

5.3 BACK-UP Connection
Inverter has on and off grid function, the inverter will deliver output power through AC port
when the grid is on, and it will deliver output power through BACK-UP port when the grid is
off.
Auto & Manual
BACK-UP function can be achieved automatically or manually according to user’s
wishes. BACK-UP function can only be triggered automatically.
1. For inverter, the standard PV installation typically consists of the connection of the
inverter with both panels and batteries. In case of systems not connected to the batteries,
the Back-Up function is strongly not advised to use. We shall not cover the standard
warranty and be liable for any consequences arising from users not following this
instruction.
2. Hybrid inverters are able to supply over load output at its Back-Up. For details please
refer to the technical parameters of inverter. And the inverter has self-protection derating
at high ambient temperature.
3. For complicated application, or Special load，please contact after-sales.
Note!
In case of discrepancies between wiring mode of local policy and the
operation guide above, especially for the wiring of neutral line,
grounding and RCD, please contact us before any operation!
Back-Up Connection:

16
When using the off grid function, please add off grid AC breaker in off grid output
cable to ensure safety.

Requirements for BACK-UP load
WARNING!
Make sure the BACK-UP load power rating is within BACK-UP output rating, otherwise the
inverter will shutdown with an “over load” warning.
When an “over load” is appeared, adjust the load power to make sure it is within the
BACK-UP output power range, then turn the inverter back on.
For the nonlinear load, please make sure the inrush power should be within the BACK-UP
output power range.
5.4 Battery Connection
Charging & discharging system of inverter is designed for high-voltage lithium battery.
Before choosing battery, please note the maximum voltage of battery cannot exceed 350V
and the rated voltage of battery cannot exceed 336V, and the battery communication should
be compatible with inverter.
Battery breaker
Before connecting to battery, please install a nonpolar DC breaker to make sure inverter can
be securely disconnected during maintenance.
