2 System Introduction 2.1 System Overview Commercial & Industrial Smart Inverter Solution integrates devices such as inverters, batteries, Smart Meters, and smart communication sticks. In a photovoltaic system, it converts solar energy into electricity to meet the power demands of commercial and industrial applications. The energy IoT devices in the system manage the electrical loads by identifying the overall power situation within the system, thereby achieving intelligent management of power for use by loads, storage in the battery, or export to the grid. • Select the battery model according to the inverter and battery compatibility list. For requirements regarding batteries used in the same system, such as whether models can be mixed or capacities must be consistent, please refer to the user manual of the corresponding battery model or contact the battery manufacturer for relevant requirements. Inverter and battery compatibility list: https://en.goodwe.com/Ftp/EN/Downloads/User%20Manual/GW_Battery%20Co mpatibility%20Overview-EN.pdf. • Due to product version upgrades or other reasons, the document content will be updated periodically. For the compatibility relationship between inverters and IoT products, please refer to: https://en.goodwe.com/Ftp/EN/Downloads/User%20Manual/GW_Compatibility- list-of-GoodWe-inverters-and-IoT-products-EN.pdf. • The PV system is not suitable for connecting devices that rely on stable power supply, such as life-sustaining medical equipment, etc. Please ensure that system power failure will not cause personal injury. The BACK-UP function is not recommended for PV systems without a battery configured, as it may cause a system power failure risk. • The BACK-UP port does not support connecting auto-transformers or isolation transformers. • The battery current may be affected by factors such as temperature, Humidity, weather conditions, etc., which may lead to battery current limiting and affect • WARNING 24
load capacity. The inverter has a UPS function with a switching time of <10ms. Please ensure the BACK-UP Loads capacity is < the inverter's rated power. Otherwise, the UPS function may fail during a grid power outage. • The BACK-UP function is not recommended for PV systems without a battery configured, as it may cause a system power failure risk. • For detailed networking and wiring schemes for each scenario, please refer to: Detailed System Wiring Diagram. • • When the inverter is in an off-grid state, it can be used normally for common household loads. However, the following loads need to be limited, such as: inductive load: inductive load power < 0.4 times the inverter's rated output power. ○ Capacitive load: total power ≤ 0.66 x inverter rated output power. ○ The inverter does not support half-wave loads. Half-wave loads: Some old or non-EMC compliant appliances (such as hair dryers, small heaters using half- wave rectification) may not work properly. ○ • In a system where the inverter operates completely off-grid, if the battery is in low light or rainy weather for a long time and cannot be replenished in time, it may lead to over-discharge, causing battery performance degradation or damage. To ensure long-term stable system operation, avoid completely draining the battery. Recommended measures are as follows: During off-grid operation, set the minimum SOC protection threshold. It is recommended to set the off-grid battery SOC lower limit to 30%. ○ When the SOC approaches the protection threshold, the system will automatically enter load limiting or protection mode. ○ If there are multiple consecutive days of insufficient sunlight and the battery SOC is too low, promptly replenish the battery using external energy sources (such as a generator or grid-assisted charging). ○ Regularly check the battery status to ensure it is within a safe operating range. ○ It is recommended to fully charge and discharge the battery every six months to calibrate the SOC accuracy. ○ WARNING 25

No. Name Description 43 Aerosol Fire Extinguishing Device 44 Document Shelf - 45 Fire Action Signal Port 46 Maintenance Hook Shelf 47 Lifting Ring Installation Hole - 48 Air Conditioner Switch Connects to the air conditioner power cable and controls the air conditioner power supply. Fire Protection System Description Monitors fire signals inside the cabinet and implements fire extinguishing. When a fire occurs, the aerosol fire extinguishing device ignites the thermal fuse upon receiving an electrical start signal or open flame. The electric igniter thermal fuse burns and activates the aerosol generator in the fire extinguishing device. The aerosol generator releases heat through a series of reactions to decompose the chemical coolant, allowing the aerosol generator and coolant to combine for fire extinguishing. Dry contact signal interface, normally NC (normally closed state). Voltage: 0-24Vdc, Current: 0.3A. Connects to the audible and visual alarm cable. When disassembling the Pack and PCU, the maintenance hook can be taken from here for operation. 43
1 2 3 4 Smoke Detector Heat Detector Aerosol Fire Extinguishing Device Temperature Detector & Smoke Detector ■ Temperature Detection Principle: The detector uses a negative temperature coefficient thermistor as the sensor, leveraging its sensitivity to ambient temperature to obtain environmental temperature information. The internal circuit converts this information into a voltage signal and transmits it to the microcontroller. The microcontroller analyzes and processes the signal using built-in intelligent algorithms to determine whether a fire alarm or fault condition is present. Smoke Detection Principle: The detector utilizes infrared light scattering principle 44 Explosion-Proof Valve
to detect fires. In a smoke-free state, it receives only very weak infrared light. When smoke enters the optical smoke detection chamber, the scattered light enhances the received light signal. When the smoke concentration reaches a certain level, an alarm signal is output. Technical Specifications Dimensions (mm) 102 × 55 Installation Requirements Screw Fixation indicator (Red) Flashes during monitoring, stays on Operating Temperature (℃) -40~+85 Relative Humidity ≤95%RH (Non-condensing) Explosion-Proof Valve ■ When the internal pressure of sealed products like battery enclosures rises rapidly, the explosion-proof check valve's exhaust port opens to quickly and directionally release the internal gas, thereby preventing explosions in sealed products such as battery boxes. Temperature Smoke Detector Detector when alarming 45
Technical Specifications Explosion Vent Valve Ingress Protection Rating IP68 Opening Area 570 mm2 Operating Temperature -40℃ ~ +130℃ Flame Retardancy UL94-V0 Aerosol Fire Extinguishing Device ■ When a fire occurs, upon receiving an electrical activation signal or when an open flame ignites the thermal fuse, the electric initiator or burning thermal fuse activates the aerosol-forming agent inside the fire extinguishing device. The heat released by the redox reaction of the aerosol-forming agent causes the chemical coolant to decompose, enabling both the aerosol-forming agent and the coolant to participate in fire suppression. Technical Specifications Aerosol Fire Extinguishing Device Operating Ambient Temperature Range -30℃ ~ +70℃ Operating Ambient Relative Humidity ≤95%RH Thermal Activation Temperature 185±10℃ 46
Fire Protection Logic The fire protection for this battery system employs a graded response design. When a fire occurs inside a battery Pack, it is first detected by the Pack-level detector, which immediately activates the Pack's internal aerosol fire extinguishing device for initial suppression. If the fire is not controlled and spreads further, cabinet-level fire protection is triggered. When both the smoke detector and temperature detector detect a fire, or when an open flame ignites the thermal fuse (at a temperature of 180°C), the cabinet-level aerosol fire extinguishing device is automatically activated for comprehensive fire suppression. The aerosol-forming agent produces extinguishing agents through a combustion reaction, and the heat released during the reaction decomposes the chemical coolant. The aerosol fire extinguishing agent and coolant work synergistically to extinguish the fire. Simultaneously, the BMS receives feedback signals from the fire protection system, triggering external audible and visual alarms until the fire is completely extinguished. 47

2.4 System Working Mode Self-Use Mode The fundamental operating mode of the system. • • PV generation prioritizes supplying power to the loads. Excess power charges the battery, and any remaining power is sold to the grid. When PV generation is insufficient to meet the loads' demand, the battery supplies power to the loads. When the battery power is also insufficient, the grid supplies power to the loads. 51
Backup Mode Recommended for use in areas with an unstable grid. • • When the grid fails, the inverter switches to off-grid operation mode, and the battery discharges to supply power to the loads, ensuring uninterrupted power for the BACK-UP Loads. When the grid is restored, the inverter switches its operation mode back to grid-tied. • To ensure the battery SOC is sufficient to maintain normal system operation during off-grid periods, the system will charge the battery using PV or grid power to the backup power SOC during grid-tied operation. If purchasing electricity from the grid to charge the battery is required, please ensure it complies with local grid regulations and laws. 52
TOU Mode Subject to compliance with local laws and regulations, buy and sell electricity during different time periods based on peak and off-peak grid electricity price differences. For example: During off-peak price periods, set the battery to charging mode to purchase electricity from the grid for charging. During peak price periods, set the battery to discharging mode to supply power to the loads via the battery. 53

It supports household loads, heat pumps, etc. The load control methods are as follows: Time control: Set the time to switch the load on or off. The load will automatically turn on or off within the set time period. • Switch control: When the control mode is set to ON, the load will turn on; when set to OFF, the load will turn off. • • BACK-UP Loads control: The inverter has a built-in relay dry contact control port, which can control whether the load is switched off via the relay. In off-grid mode, if an overload is detected on the BACK-UP port and the battery SOC value falls below the off-grid protection setting, the load connected to the relay port can be switched off. Rapid Shutdown（RSD） In a rapid shutdown system, the rapid shutdown transmitter and receiver work together to achieve rapid system shutdown. The receiver maintains module output by receiving signals from the transmitter. The transmitter can be external or built into the inverter. In an emergency, by enabling an external triggering device, the transmitter can be deactivated, thereby shutting down the modules. 63
