It is necessary to confirm that the solar charge inverter is the only input device for load equipment, and it is forbidden to use it in parallel with other input AC power to avoid damage.

2.2 Wiring specifications and circuit breaker selection
Wiring and installation must comply with national and local electrical codes.
Recommended PV array wiring specifications and circuit breaker selection: 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.

• Refer to the table below for PV input wire diameter and switch:
  Models| Recommended PV wiring diameter| Maximum PV input current| Recommended circuit breaker type
  ---|---|---|---
  SPH5048P| 6mm2/10AWG| 22A| 2P—25A

Note: The voltage in series shall not exceed the maximum PV input open circuit voltage.

• Refer to the table below for recommended AC input wire diameter and switch:
  Models| Recommended AC input wiring diameter| Maximum bypass input current| Recommended circuit breaker type
  ---|---|---|---
  SPH5048P| 10mm2/7AWG| 63A| 2P—63A

Note: There is already an appropriate circuit breaker at the Mains input wiring terminal, so it is not necessary to add one more.

• Recommended battery input wire diameter and switch selection
  Models| Recommended battery wiring diameter| Rated battery discharge| Maximum charge current| Recommended circuit breaker type
  ---|---|---|---|---
  SPH5048P| 30mm2/7AWG| 125A| 100A| 2P—200A
• Recommended AC output wiring specifications and circuit breaker selection
  Models| Recommended AC output wiring diameter| Rated inverter AC output current| Maximum bypass output current| Recommended circuit breaker type
  ---|---|---|---|---
  SPH5048P| 10mm2/7AWG| 42A| 63A| 2P—63A

Note: The wiring diameter is for reference only. If the distance between the PV array and the all-in-one solar charge inverter or the distance between the all-in-one solar charge inverter and the battery is relatively long, using a thicker wire can reduce the voltage drop to improve system performance.
Note: The above are only recommended wiring diameter and circuit breaker. Please select the appropriate wiring diameter and circuit breaker according to actual situations.
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 m 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, opening 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;
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.

Note: The grounding wire shall be as thick as possible (cross-sectional area is not less than 4mm).
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: When used in parallel connection, different machines need to be connected to different PV arrays or PV sources.

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 6mm is recommended. The Otype 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.

Warnings:

1. Mains input, AC output and PV array will generate high voltage. So, before wiring, be sure to opening 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.

4. Settings [38] need to be set consistently or only for the host. When the machine is running, the voltage set by the host shall prevail, and the master will force the rewrite of the other slave machines to keep the same set. Only can be set in the standby mode.
5. Machine factory default for single machine mode, if you use parallel, split-phase or threephase function, you need to set the [31] item parameters through the screen. The setting method is: power on one machine at a time,  therest of the machine off, and then set the [31] item parameters according to the site system  operation mode.After this machine is  set successfully,turn off the machine switch and wait for the machine to be powered down, then set the  rest of the machinesin turn until  all machines are set, and then all machines are powered up again at the same time and enter the working state. The [31] setting item： When in single phase parallel connection : setting【31】should be  setas 【PAL】 When in single phase parallel connection, setting 31】 should be set as follows：When in three phase parallel connection ,all machines in phase 1 must be set as 【3P1】, all machines in phase 2 must be set as 【3P2】 all machines in phase 3 must be set as 【3P3】, at present, the voltage phase difference between P1-P2, P1-P3 and P2-P3 is 120 degrees.
   a. When the output voltage set in the setting 【38】 is 120 Vac (U model), the line voltage between L1 in phase 1 and L2 in phase 2 is 1201.732 = 208 Vac, similarly the line voltage between L1-L3, L2-L3 is 208 Vac; the single phase voltage between L1-N,  L2-N, L3-N is 120 Vac.
   b. When the output voltage set in the setting【38】 is 230Vac (S model), the line voltage between the live wire L1 in phase 1 and the live wire L2 in phase 2 is 2301.732 = 398Vac, and similarly the line voltage between L1-L3, L2-L3 is 398Vac; the single phase voltage between L1-N, L2-N, L3-N is 230Vac.
   In split phase parallel connection (U) ,All connected P1-phase inverters are set to “2P0″：

1. If all connected P2-phase inverters are set to “2P1”, AC output line voltage difference is 120 degrees (L1-L2), line voltage is 120*1.732= 208Vac; Phase voltage is 120Vac (L1-N; L2-N).
2. If all connected P2-phase inverters are set to “2P2”, AC output line voltage difference is 180 degrees (L1-L2), line voltage is 120*2= 240Vac; Phase voltage is 120Vac (L1-N; L2-N).

6.  After the system runs, the output voltage is measured correctly, and then the load setting is connected.

Operating modes

3.1 Charging mode

1. Solar First: priority shall be given to charging by PV, and mains charging will be started only when the PV has failed. It can fully utilize solar energy to generate power in the daytime and then switch to mains charging to keep the battery level, and can be used in regions where the grid is relatively stable and the feed-in tariff is relatively expensive.
2. Mains First: priority shall be given to charging by Mains Power, and charging with PV power will be started only when the Mains has failed.
3. Hybrid Charging: hybrid charging of PV and Mains Power, give priority to PV MPPT charging, and supplement Mains Power when PV energy is insufficient. When the PV energy is sufficient, the Mains Power will stop charging. This is the mode of fast charging and suitable for unstable areas of power grid, and can provide sufficient backup power at any time.
4. Only Solar: Only PV charging, no mains charging is initiated. This is the most energy-efficient mode and the battery power comes from solar energy, which is usually used in regions with good daylighting conditions.

3.2 Output mode

1. Solar First: PV and battery will power the load, with diversified charging modes available and output mode optional, when the Solar First Mode is selected, the use of green solar energy can be maximized for energy efficiency and emission reduction. Switch to Mains Power when PV has failed. This mode can maximize the use of solar energy while maintaining the battery power, which is suitable for regions with relatively stable power grid.
2. Mains First: switch to inverter power supply only when Mains Power has failed, which is equivalent to backup UPS and is used in regions with unstable power grid.
3. Inverter First: switch to Mains Power supply only when the battery is under-voltage. This mode uses DC energy to the maximum extent and is used in regions with stable power grid.
4. Hybrid output and gird connection（need to be abled) In the utility bypass state, when no battery is connected or when the battery is full, the load power is supplied by the PV and the utility together if the hybrid function is enabled, and the surplus PV energy is fed back to the grid if the grid connection function is enabled.

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!
