short-circuit of the battery. Acid gas may be generated when the battery is
charged. So, please ensure good ventilation. When installing the cabinet, be
sure to leave enough space around the all-in-one solar charge
inverter for heat dissipation. Do not install the all-in-one solar charge
inverter and lead-acid battery in the same cabinet to avoid corrosion by acid
gas generated during battery operation. Only the battery that meets the
requirements of the all-in-one unit can be charged. Poorly connected
connections and corroded wires may cause great heat which will melt the wire
insulation, burn the surrounding materials, and even cause fires. So, make
sure the connectors have been tightened, and the wires are secured with ties
to avoid looseness of connections caused by shaking of wires during mobile
application. The system connection wires are selected according to a current
density of not more than 5 A/mm2. Avoid direct sunlight and rainwater
infiltration for outdoor installation. Even after the power is turned off,
there is still high voltage inside the unit. Do not open or touch the internal
components, and avoid related operations until the capacitor completely
discharges. Do not install the all-in-one solar charge inverter in harsh
environments such as moist, oily, flammable or explosive, or heavily dusty
areas. Polarity at the battery input end of this product shall not be
reversed, otherwise it may damage the device or cause unpredictable danger.
The mains input and AC output are high voltage, so please do not touch the
wiring terminals. When the fan is working, do not touch it to prevent injury.
Load equipment input power needs to confirm that this all-in-one solar charge
inverter is the only input device, and it is forbidden to use in parallel with
other input AC power to avoid damage. It is necessary to confirm that the

Since the output current of the PV array is affected by the type, connection
method and illumination angle of the PV module, the minimum wire diameter of
the PV array is calculated according to its short-circuit current; refer to
the short-circuit current value in the PV module specification (the short-
circuit current is constant when the PV modules are connected in series; the
short-circuit current is the sum of the short-circuit currents of all PV
modules connected in parallel); the short-circuit current of the PV array
shall not exceed the maximum input current.

3. Operating modes
3.1 Charging mode
- PV priority: PV module will charge the battery preferentially, and the battery is charged by the Mains only when the PV system fails. During the day, solar energy is fully used to charge, while at night, it converts to the Mains. This can maintain battery level, and is ideal for areas where the grid is relatively stable and electricity price is relatively high.
- Mains priority: The Mains supply is preferentially used to charge the battery. Only when the Mains fails, the PV charging can be activated.
- Hybrid charging: PV and mains hybrid charging. PV MPPT charging is a priority, and when PV energy is insufficient, the mains supply supplements. When the PV energy is sufficient again, the mains stops charging. This is the fastest charging mode, suitable for the areas where power grid is unstable, providing sufficient backup power supply at any time.
- Only Solar (Only Solar): Only PV charging, without Mains charging. This is the most energyefficient way in which battery is charged only by solar panels, and is usually used in areas with good lighting conditions.
All-in-one solar charge inverter V2.0
28
3.2 Output mode
PV priority mode: Switch to mains supply when the PV charging fails. This mode
maximizes the use of solar energy while maintaining battery power, suitable
for use in the areas with relatively stable grid. Power supply
prioritySolar–Utility–Battery.
Mains priority mode: Switch to inverter only when the mains fails (when there
was mains power, switch to mains power for charging and power supply).Then,
the unit is equivalent to a backup UPS, suitable for areas with unstable grid.
Switching does not affect PV charging. Power supply priorityUtility–
Solar–Battery.
Battery priority mode:
Switch to mains supply only when the battery discharge undervoltage is lower
than the set point (item 04). When the charging battery is higher than the set
point of (05 setting item), switch to the battery discharge mode. This can
cycle the battery charge and discharge. This mode maximizes the use of DC
power and is used in the area with stable grid. Switching does not affect PV
charging. Power supply prioritySolar–Battery–Utility.

5. Other functions
5.1 Dry contact
Working principle: This dry contact can control the ON/OFF of the diesel
generator to charge the battery. Normally, the terminals are that the NC-N
point is closed and the NO-N point is open; When the battery voltage reaches
the low voltage disconnection point, the relay coil is energized, and the
terminals turn to that the NO-N point is closed while NC-N point is open. At
this point, NO-N point can drive resistive loads: 125VAC/1A, 230VAC/1A,
30VDC/1A.
5.2 RS485 communication port
This port is an RS485 communication port which comes with two functions:
RS485-2 allows direct communication with the optional host computer
developed by our company through this port, and enables monitoring of the
equipment running status and setting of some parameters on the computer;
RS485-1/RS485-2 also allows direct connection with the optional RS485 to
WiFi/GPRS communication module developed by our company through this port.
After the module is selected, you can connect the all-in-one solar charge
inverter through the mobile phone APP, on which you can view the operating
parameters and status of the device.
As shown in the figure: RS485-1: Pin 1 is 5V power supply, Pin 2 is GND, Pin 7
is RS485-A1, and Pin 8 is RS485-B1; RS485-2: Pin 1 is 5V power supply, Pin 2
is GND, Pin 7 is RS485-A2, and Pin 8 is RS485-B2;
5.3 USB communication port
This is a USB communication port, which can be used for USB communication with
the optional PC host software. To use this port, you should install the
corresponding “USB to serial chip CH340T driver” in the computer.
All-in-one solar charge inverter V2.0

5.4 Parallel communication function (parallel operation only)
a) This port is used for parallel communication, through which the parallel modules can communicate
with each other.
b) Each inverter has two DB15 ports, one for the male connector and the other for the female
connector.
c) When connecting, make sure to connect the male connector of the inverter with the female
connector of the inverter to be paralleled, or connect the female connector of the inverter to the
male connector of the inverter to be paralleled.
d) Do not connect the male connector of the inverter to its female connector.
Female connector
Male connector
5.5 Current sharing detection function (parallel operation only)
a) This port is used for current sharing detection, through which the current
sharing of the parallel modules can be detected (parallel operation only).
b) Each inverter has two current sharing detection ports, which are connected
in parallel. When it is connected to other models to be paralleled, either
port can be connected for convenience. There is no special mandatory wiring
requirements.

Faults
Remedy
No display on the screen Battery overvoltage protection
Check if the battery the PV air switch has been closed; if the switch is in
the “ON” state; press any button on the screen to exit the screen sleep mode.
Measure if the battery voltage exceeds rated, and turn off the PV array air
switch and Mains air switch.
Battery undervoltage protection
Charge the battery until it returns to the low voltage disconnection recovery voltage.
Fan failure
Heat sink over temperature protection Bypass overload protection, inverter
overload protection Inverter short circuit protection
PV overvoltage
Check if the fan is not turning or blocked by foreign object.
When the temperature of the device is cooled below the recovery temperature,
normal charge and discharge control is resumed. Reduce the use of power
equipment; Restart the unit to resume load output. Check the load connection
carefully and clear the shortcircuit fault points; Re-power up to resume load
output.
Use a multimeter to check if the PV input voltage exceeds the maximum
allowable input voltage rated.
Battery disconnected alarm
Check if the battery is not connected or if the battery circuit breaker is not closed.
Parallel connection fault
Check whether the parallel line is not connected well, such as loose or wrong connection.
Parallel ID setting error
Check whether the setting of parallel ID number is repeated.
Parallel current sharing fault
Check whether the parallel current sharing line is not connected well, such as loose or wrong connection.
Inconsistent AC input source in parallel mode
Check whether the parallel AC inputs are from the same input interface.
Inconsistent system firmware version in parallel mode
Check whether the software version of each inverter is consistent.

7.Troubleshooting
In order to maintain the best long-term performance, it is recommended to
conduct following checks twice a year. 1. Make sure that the airflow around
the unit is not blocked and remove any dirt or debris from the heat sink. 2.
Check that all exposed wires are damaged by exposure to sunlight, friction
with other objects around them, dryness, bite by insects or rodents, etc., and
the wires shall be repaired or replaced if necessary. 3. Verify for the
consistency of indication and display with the operation of the device. Please
pay attention to the display of any faults or errors, and take corrective
actions if necessary. 4. Check all wiring terminals for corrosion, insulation
damage, signs of high temperature or burning/discoloration, and tighten the
screws. 5. Check for dirt, nesting insects and corrosion, and clean up as
required. 6. If the arrester has failed, replace in time to prevent lightning
damage to the unit or even other equipment of the user.
Warning: Danger of electric shock! When doing the above operations, make sure
that all power supplies of the all-in-one machine have been disconnected, and
all capacitors have been discharged, and then check or operate accordingly!
