2.3 System connection diagram
The diagram below shows the system application scenario of this product. A complete system consists of the following components: 1. 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. 2. 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. 3. 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. 4. Home load: Various household and office loads can be connected, including refrigerators, lamps, televisions, fans, air conditioners, and other AC loads. 5. Inverter: The energy conversion device of the whole system. The actual application scenario determines the specific system wiring method.

6.4 Time-slot charging/discharging function
The SOEC-AO-MB51400-10KW/SOEC-AO-MB51300-10KW 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.
Before using this function for the first 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.

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.

after 10s. Load > 125% ±10%: error reported and output switched

off after 5s.

AC output reverse

Prevents AC back flow from the battery inverter to the bypass AC input.

Bypass over-current protection

Built-in AC input over-current protection circuit breaker.

Bypass phase inconsistency
protection

When the phase of the bypass input and the phase of the inverter split do not match, the inverter disables switching to the bypass output to prevent the load from dropping out or short-circuiting when switching to the bypass.

9.2 Maintenance
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 product 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 anti insects net as required. 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 product 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 product.
