2.3 Installation and wiring

Installation steps:

Step 1: Determine the installation position and the space for heat dissipation. Determine the installation  position of the all-in-one solar charge inverter, such as wall surface; when installing the all-in-one solar charge inverter, ensure that there is enough air flowing through the heat sink, and space of at least 200m  to the left and right air outlets of the inverter shall be left to ensure natural convection heat dissipation.  Refer to the installation diagram of the whole machine as above.

Warning:  Danger of explosion! Never install the all-in-one solar charge inverter and lead-acid  battery in the same confined space! Also do not install in a confined place where battery gas may  collect.

Step 2:  Remove the terminal cover

Step3: Wiring

AC input / output wiring method:

① Prior to AC input/output wiring, disconnect the external circuit breaker and confirm that  the wire used is thick enough. Please refer to Section 2.2 “Wiring Specifications and Circuit  Breaker Selection”;

② Properly connect the AC input wire according to the wire sequence and terminal position  shown in the figure below. Please connect the ground wire first, and then the live wire and  the neutral wire;

：Ground L：Live N：Neutral

③ Properly connect the AC output wire according to the wire sequence and terminal  position shown in the figure below. Please connect the ground wire first, and then  the live wire and the neutral wire. The ground wire is connected to the grounding  screw hole on the cabinet through the O-type terminal.

：Ground L：Live N：Neutral

Note: The grounding wire shall be as thick as possible (cross-sectional area is not less than 4mm2).  The grounding point shall be as close as possible to the all-in-one solar charge inverter. The  shorter the grounding wire, the better.

PV input wiring method:

① Prior to wiring, disconnect the external circuit breaker and confirm that the wire used  is thick enough. Please refer to Section 2.2 “Wiring Specifications and Circuit  Breaker Selection”;

② Properly connect the PV input wire according to the wire sequence and terminal  position shown in the figure below.

PV+: PV input positive pole PV-: PV input negative pole

BAT wiring method:

① Prior to wiring, disconnect the external circuit breaker and confirm that the wire used  is thick enough. Please refer to Section 2.2 “Wiring Specifications and Circuit  Breaker Selection”. The BAT wire needs to be connected to the machine through  the O-type terminal. The O-type terminal with an inner diameter of 5 mm is  recommended. The O-type terminal shall firmly press the BAT wire to prevent  excessive heat generation caused by excessive contact resistance;

② Properly connect the BAT wire according to the wire sequence and terminal position  shown in the figure below.

BAT+: Battery positive electrode BAT-: Battery negative electrode

Warnings:

① Mains input, AC output and PV array will generate high voltage. So, before wiring, be sure to  disconnect the circuit breaker or fuse;

② Be very careful during wiring; do not close the circuit breaker or fuse during wiring, and ensure that  the “+” and “-” pole leads of each component are connected properly; a circuit breaker must  be installed at the battery terminal. Refer to Section 2.2 “Wiring Specifications and Circuit Breaker Selection” to select a right circuit breaker. Before wiring, be sure to disconnect the circuit breaker

to prevent strong electric sparks and avoid battery short circuit; if the all- in-one solar charge  inverter is used in an area with frequent lightning, it is recommended to install an external  lightening arrester at the PV input terminal.

Step 4:  Check if the wiring is correct and firm. In particular, check if the battery polarity is reversed, if the  PV input polarity is reversed and if the AC input is properly connected.

Step 5: Install the terminals cover.

Step 6: Turn on the all-in-one solar charge inverter

First, close the circuit breaker at the battery terminal, and then turn the rocker switch  on the left side of the machine to the “ON” state. The “AC/INV” indicator flashing  indicates that the inverter is working normally. Close the circuit breakers of the PV  array and the Mains. Finally, turn on AC loads one by one as the AC output is normal  to avoid a protection action caused by a large momentary shock due to simultaneous turning on the loads simultaneously. Now, the machine goes into a normal operation according to the set mode.

Note: If power is supplied to different AC loads, it is recommended to first turn on the load with a large  surge current. After the load is stable, turn on the load with a small surge current.

Note:  If the all-in-one solar charge inverter does not work properly or the LCD or indicator is abnormal,  refer to Chapter 6 to handle the exceptions.

3. Operating modes

3.1 Charging mode

1) 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.

2) Mains priority: The Mains supply is preferentially used to charge the battery. Only when the  Mains fails, the PV charging can be activated.

3) 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.

4) Only Solar (Only Solar): Only PV charging, without Mains charging. This is the most energy efficient way in which battery is charged only by solar panels, and is usually used in areas with  good lighting conditions.

3.2 Output mode

1) PV priority mode: Priority use of photovoltaic, battery energy to power the load, photovoltaic  priority carry load, excess power to battery charging, photovoltaic priority carry load, excess  power to battery charging; when photovoltaic ineffective switch to utility power supply and  charging. This mode maximizes the use of solar energy, while maintaining battery power, and is  suitable for areas with relatively stable power grid

2) 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.

3) Inverter 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.

4) Mixed functions mode: When the battery is not available or the battery is fully charged, the load is provided by PV and commercial power, PV maximum output power output。
