2.3System connection diagram
The diagram below shows the system application scenario of this product. A complete system consists of the following components:
· PV modules: converts light energy into DC energy, which can be used to charge the battery via an
inverter or directly inverted into AC power to supply the load.
· Utility grid or generator: connected to the AC input, it can supply the load and charge the battery at the
same time. The system can also operate generally without the mains or generator when the battery and the PV module power the load.
· Battery: The role of the battery is to ensure the regular power supply of the system load when the solar
energy is insufficient and there is no mains power
· Home load: Various household and office loads can be connected, including refrigerators, lamps,
televisions, fans, air conditioners, and other AC loads.
· Inverter: The energy conversion device of the whole system.

3. Installation
3.1Select the mount location
SPH series are designed for INDOOR USE ONLY (IP20) . Please consider the followings before selecting the location
· Choose the solid wall to install the inverter. · Mount the inverter at eye level. · Adequate heat dissipation space must be provided for the inverter. · The ambient temperature should be between -10~55 (14~131) to ensure optimal operation.
! DANGER
· Do not install the inverter where highly flammable materials are near by. · Do not install the inverter in potential explosive areas. · Do not install the inverter with lead-acid batteries in a confined space.
! CAUTION
· Do not install the inverter in direct sunlight. · Do not install or use the inverter in a humid environment.

3.2Mount the inverter
Make 4 mounting holes in the wall with an electric drill according to the specified dimensions, insert 2 expansion screws above and fix the inverter with 2 M5 screws below.
3.3Remove the terminal cover & anti insect net
Using a screwdriver, remove the terminal protection cover and anti insect net.
! NOTICE
When using the device in areas with poor air quality, the dust screen is easily blocked by airborne particles. Please dismantle and clean the dust screen regularly to avoid affecting the internal air flow rate of the inverter, which may trigger an over-temperature protection fault (19/20 fault) affecting the use of the power supply and the service life of the inverter.

· Only Solar Chargin OSO
Solar charging only, no mains charging is activated. This is the most energy- efficient method, with all the battery power coming from solar energy, and is usually used in areas with good radiation conditions.

5.5Time-slot charging/discharging function
The SPH series is equipped with a time-slot charging and discharging function, which allows users to set different charging and discharging periods according to the local peak and valley tariffs, so that the utility power and PV energy can be used rationally.
When mains electricity is expensive, the battery inverter is used to carry the load; when the mains electricity is cheap, the mains electricity is used to carry the load and charge, which can help customers to save electricity costs to the greatest extent.
The user can turn on/off the time-slot charging/discharging function in setup menu parameter 46 and 53.and set charging and discharging slot in parameter 40-45, 47-52. Below are examples for users to understand the function.
! NOTICE
Before using this function for the ffrst time, please set the local time in parameter items 54, 55, then the user can set the corresponding time slot according to the local peak and valley tariff charges.

Time-slot Utility Charging/Carrying Function

Time-slot Battery Disacharging Function

With 3 definable periods, the user can freely set the mains charging/carrying time within the range of 00:00 to 23:59. During the time period set by the user, if PV energy is available, PV energy will be used first, and if PV energy is not available or insufficient, utility energy will be used as a supplement.

With 3 definable time periods, users can freely set the battery discharge time within the range of 00:00 to 23:59. During the time period set by the user, the inverter will give priority to the battery inverter to carry the load, and if the battery power is insufficient, the inverter will automatically switch to mains power to ensure stable operation of the load.

8.2Maintenance
To maintain optimum and long-lasting working performance, we recommend that the following items are checked twice a year. 1. Ensure that the airflow around the inverter is not blocked and remove any dirt or debris from the radiator. 2. Check that all exposed conductors are not damaged by sunlight, friction with other surrounding objects,
dry rot, insect or rodent damage, etc. The conductors need to be repaired or replaced if necessary. 3. Verify that the indications and displays are consistent with the operation of the equipment, note any
faults or incorrect displays and take corrective action if necessary. 4. Check all terminals for signs of corrosion, insulation damage, high temperatures or burning/discolouration
and tighten terminal screws. 5. Check for dirt, nesting insects and corrosion, clean as requiredClean the insect screen regularly. 6. If the lightning arrester has failed, replace the failed arrester in time to prevent lightning damage to the
inverter or other equipment of the user.

· Make sure that the inverter is disconnected from all power sources and that the capacitors are
fully discharged before carrying out any checks or operations to avoid the risk of electric shock.
The Company shall not be liable for damage caused by : 1. Damage caused by improper use or use in a wrong location. 2. Photovoltaic modules with an open circuit voltage exceeding the maximum permissible voltage. 3. Damage caused by the operating temperature exceeding the restricted operating temperature range 4. Dismantling and repair of the inverter by unauthorised persons. 5. Damage caused by force majeure: damage during transport or handling of the inverter.
