The voltage must be lower than the Max. Input Voltage. Damage caused by reverse polarity or Overvoltage is not covered by the equipment manufacturer's liability. • PV string outputs do not support grounding. Before connecting PV strings to the inverter, ensure that the minimum insulation resistance of the PV strings to ground meets the minimum insulation resistance requirement (R=Max. Input Voltage (V)/30mA). Do not connect the same PV string to multiple inverters, as this may damage the inverters. • PV modules used with the inverter must comply with IEC 61730 Class A. • A high PV string input voltage or input current may cause the inverter's output power to be derated. • 1.3.2 Inverter Safety WARNING 17
Ensure that the voltage and frequency at the grid connection point meet the inverter's grid-connection specifications. • • It is recommended to install Protection devices such as a circuit breaker or fuse on the inverter AC side. The rating of the Protection device must be greater than 1.25 times the inverter's AC output Max. Current. • If the inverter triggers an Arc Failure alarm fewer than five times within 24 hours, the alarm can be cleared automatically. After the fifth Arc Failure alarm, the inverter shuts down for Protection. The fault must be cleared before the inverter can resume normal operation. If no battery is configured in the PV system, use of the BACK-UP function is not recommended, as it may result in a risk of system power outage. • Changes in grid voltage and frequency may cause the inverter to derate its output power. • 1.3.3 Battery Safety WARNING 18

2 System Overview 2.1 System Overview The C&I smart inverter solution integrates inverters, static transfer switch cabinets, batteries, smart energy control boxes, smart meters, smart communication sticks, and other equipment. In a PV system, it converts solar energy into electrical energy or purchases electricity from the grid to meet the electricity needs of commercial and industrial users. By monitoring the system's overall power status, the energy IoT devices in the system manage power-consuming equipment, enabling intelligent management of electricity for use by loads, storage in batteries, or export to the grid. • The PV system is not suitable for connecting equipment that requires a stable power supply, such as life-support medical equipment. Ensure that a system power failure will not result in personal injury. • Avoid using loads with high starting currents in the PV system, such as high- power water pumps. Otherwise, excessive transient current may cause off-grid output failure. If no battery is configured in the PV system, use of the BACK-UP function is not recommended, as it may result in a risk of system power outage. • • Battery Current may be affected by factors such as temperature, humidity, and weather conditions. This may cause the battery current to be limited and affect its load-carrying capacity. • If the inverter triggers Overload Protection once, it can restart automatically. If this occurs multiple times, the inverter restart interval will increase. To restart the inverter as soon as possible, restart it immediately via the SolarGo app. • When the inverter is operating in off-grid mode, it can supply C&I loads normally, such as: Motor loads: ○ If the power of a single-phase motor is greater than or equal to3kWor the power of a three-phase motor is greater than or equal to8kW, aVFD/VSD； ■ The total Rated Power of single-phase motor loads must not exceed0.5*Pn/3, and the total Rated Power of all motor loads must not exceed0.5*Pn； ■ WARNING 26
The total power of motor loads connected to a single inverter must not exceed25kW；2or2or more inverters operating in parallel may be connected to motor loads with a total power not exceedingPn*50%*number of parallel inverters*80%； ■ If other loads are present, reduce the motor load accordingly and calculate based on the specific application conditions. ■ Capacitive loads: total power ≤ 0.33Pn。Pnrefers to the inverter's rated output power. ○ The inverter does not support half-wave loads. ○ • In a fully off-grid inverter system, if the battery remains under low-irradiance or rainy conditions for an extended period and is not recharged in time, it may be over-discharged, resulting in degraded battery performance or damage. To ensure long-term stable system operation, avoid fully discharging the battery. Recommended measures are as follows: When operating off-grid, set the minimum SOC Protection threshold. It is recommended to set the lower limit of the off-grid battery SOC to 30%. 1. When the SOC approaches the Protection threshold, the system automatically enters load-limiting or Protection mode. 2. 3. If sunlight is insufficient for several consecutive days and the battery SOC is too low, recharge the battery promptly using an external energy source, such as a generator or supplementary charging from the grid. Check the battery status regularly to ensure it remains within a safe operating range. 4. It is recommended to fully charge and discharge the battery once every six months to calibrate SOC accuracy. 5. When the inverter is in off-grid mode, it can supply power to commercial and industrial loads for normal operation.

No. Name Description 43 Aerosol fire suppression device 44 Document holder - 45 Fire Alarm Activation Signal Port 46 Maintenance Hook Holder 47 Lifting Eye Installation Hole - 48 Air Conditioner Switch Connect the air conditioner power cable to control its power supply. Fire Protection System Description Monitors fire signals inside the cabinet and performs fire suppression. When a fire occurs, the aerosol fire suppression device ignites the thermal cord upon receiving an electrical activation signal or detecting an open flame. The electric igniter's thermal cord burns and activates the aerosol generator in the suppression device. Heat released through a series of reactions in the aerosol generator decomposes the chemical coolant, enabling the generator and coolant to work together to extinguish the fire. Dry-contact signal interface, normally NC (normally closed); connect the cables for the audible and visual alarm. Permissible external voltage and current: Voltage: 0–24 Vdc • Current: 0.3 A • When removing the Pack and PCU, retrieve the maintenance hook from here. 45
1 2 3 4 Smoke detector Heat detector Aerosol fire suppression device Heat Detector & Smoke Detector ■ Temperature Detection Principle:The detector uses a negative temperature coefficient (NTC) thermistor as its sensor. It detects ambient temperature based on the thermistor's sensitivity to changes in ambient temperature. The internal circuit converts this information into a voltage signal and sends it to the microcontroller, which analyzes and processes the signal using an embedded intelligent algorithm to determine whether a fire alarm or fault condition is present. Smoke Detection Principle:The detector uses the infrared light-scattering principle 46 Explosion-proof valve
to detect fires. In the absence of smoke, it receives only a weak infrared signal. When smoke particles enter the optical smoke detection chamber, scattering increases the received light signal. Once the smoke concentration reaches a certain level, an alarm signal is output. Technical Specifications Heat detector Smoke detector Dimensions (mm) 102 × 55 Installation Requirements Screw-mounted Indicator (red) Flashes during monitoring and remains lit during an alarm Operating Temperature (°C) -40~+85 Relative Humidity ≤95% RH (non-condensing) Explosion-proof valve ■ When the internal pressure of a sealed product such as an enclosure rises rapidly, opening the vent outlet of the explosion-proof one-way valve rapidly releases the internal gas in a controlled direction, preventing sealed products such as battery enclosures from exploding. Technical Specifications Explosion Vent Valve Ingress Protection Rating IP68 47
Technical Specifications Explosion Vent Valve Opening Area 570 mm2 Operating Temperature -40℃ ~ +130℃ Flame-retardant Performance UL94-V0 Aerosol fire suppression device ■ In the event of a fire, after receiving an electrical activation signal or when exposed to an open flame, the electric igniter or thermosensitive cord activates the aerosol- generating agent in the fire suppression device. Heat released by the agent through an oxidation-reduction reaction decomposes the chemical coolant, enabling both the aerosol-generating agent and coolant to contribute to fire suppression. Technical Specifications Aerosol fire suppression device Operating Ambient Temperature Range -30℃ ~ +70℃ Operating Ambient Relative Humidity ≤95%RH Hot Start Temperature 185±10℃ Fire Protection Logic The fire protection system for this battery system uses a tiered response design. In 48
the event of a fire inside a battery pack, the pack-level detector detects it first and immediately activates the aerosol fire suppression device inside the pack to contain the fire in its early stages. If the fire cannot be contained and spreads further, the cabinet-level fire protection system is triggered. When both the smoke detector and temperature detector detect a fire, or when an open flame ignites the heat-sensitive cable (at a temperature of 180°C), the cabinet-level aerosol fire suppression device is automatically activated to extinguish the fire throughout the cabinet. The aerosol- forming agent produces a fire extinguishing agent through a combustion reaction. The heat released during the reaction decomposes the chemical coolant, allowing the aerosol extinguishing agent and coolant to work together to extinguish the fire. At the same time, the BMS receives a feedback signal from the fire protection system and activates the external audible and visual alarm until the fire is completely extinguished. 49

2.4 System Modes Self-Consumption Mode The system's basic operating mode. • • PV power is used first to supply the loads. Any surplus power charges the battery, and any remaining power is exported to the grid. If PV generation is insufficient to meet the load demand, the battery supplies the loads. If the battery charge is also insufficient, the grid supplies the loads. Backup Mode Recommended for areas with an unstable grid. • • When a Grid Power Outage occurs, the inverter switches to off-grid operation, and the battery discharges to supply the loads and ensure uninterrupted power to the BACK-UP loads. When grid power is restored, the inverter switches to grid- connected operation. To ensure that the battery SOC is sufficient for normal system operation when off- • 53
grid, the battery is charged to the backup power SOC using PV power or electricity purchased from the grid while the system is grid-connected. If you need to purchase electricity from the grid to charge the battery, confirm that this complies with local grid laws and regulations. 54
TOU Mode Where permitted by local laws and regulations, set different time periods for purchasing and Export Energy based on variations in the grid Tariff during peak and off-peak periods. For example, set the battery to charging mode during off-peak periods to charge it using electricity purchased from the grid; during peak periods, set the battery to discharging mode to supply the loads. 55
