Fire protection: PDF page 11: Despite the extremely stable chemical properties of lithium iron phosphate batteries and the multiple protections, each battery unit is equipped with a fire protection module to further ensure the safety and reliability of Fox ESS batteries. This innovative module utilizes a new type of aerosol fire extinguishing device with features such as pressure-free storage, no maintenance required, high extinguishing efficiency, non-toxic and harmless characteristics.; PDF page 11: The fire extinguishing mechanism of thermal aerosols involves two main mechanisms: the cooling effect from endothermic decomposition and the chemical suppression effects in both gas and solid phases, which work synergistically. Additionally, the gaseous components in the products of the aerosol extinguishing agent also play a supportive role.; PDF page 12: Activation method: Thermal activation Thermal activation temperature: ≥ 170°C Discharge time: ≤ 5 seconds Notes: Please contact Fox ESS for immediate replacement if the fire protection module is activated. Non-professionals should not disassemble the battery without authorization. Do not touch the device until the casing has cooled after the internal fire extinguisher has been activated to prevent burns. For further assistance, please contact an authorized personnel or Fox ESS for further instructions.

Low SOC storage: PDF page 33: After the product is powered off, static power consumption and self-discharge loss may occur in internal modules. Therefore, charge batteries in a timely manner and do not store the product in low SOC. Otherwise, the product may be damaged due to overdischarge, and battery modules need to be replaced. Storage in low SOC may occur in the following scenarios:; PDF page 34: The DC Switch on the power control module is OFF.  The power cables or signal cables are not connected.  The batteries cannot be charged due to a system fault after discharge.  The batteries cannot be charged due to incorrect configurations in the system.  The batteries cannot be charged due to no PV input and long-term mains failure. Regardless of scenarios, the batteries must be charged within the longest interval corresponding to the SOC when the batteries are powered off. If the batteries are not charged within the specified interval, they may be damaged due to overdischarge. Storage environment temperature Power-Off SOC Before Storage Maximum Charge Interval 0~35°C 0% ≤ SOC < 5% 7 days Note: When the battery SOC decreases to 0%, charge the batteries within seven days. Permanent battery faults caused by delayed charge due to customer reasons are beyond the warranty scope.

Operating sequence: PDF page 28: When the grid connected system is started, the inverter should be turned on first to avoid the current pulse of the inverter increasing to the battery pack.  All installation and operation must comply with local electrical standards.  Check all power cables and communication cables carefully. System Start Up: When the inverter is connected to the PV and the grid and both are operating normally, turn on the battery DC Switch. Press the Power switch and hold it for 3 seconds, then release. The Status LED is blinking green and indicates that the system is working normally. System Shut Down: Press and hold the Power Switch for at least 5 seconds until all of the LEDs (BMS Status LED and SOC LED) begin blinking. Once they start blinking, release the switch. The lights will automatically turn off after 5 seconds. Then, turn off the DC Switch. System Black Start: Under special circumstances when both PV and Grid power are out of order, the battery can be activated through the "Black Start" function. This means that our energy storage inverter and battery can continue to operate. The startup steps for Black Start are as follows:  Turn on the DC Switch, press and hold the Power Switch for 3 seconds, then release.  Press the Power Switch three times in succession within 4 seconds (Complete within 30 seconds after the battery system starts up).  The Status LED remains solid green, indicating successful activation of Black Start mode. Note: Ensure correct battery-inverter connection prior to Black Start. No cable modifications during Black Start.

Maintenance schedule: PDF page 33: Regularly check whether the service environment of the battery meets the requirements, and the installation position should be far away from the heat source.; PDF page 33: Regularly check whether the battery and its supporting terminals, connecting cables and indicator lights are normal.; PDF page 34: When the red / green LED on the panel is flashing or normally on, it does not mean that the CQ16 is abnormal, it may be just an alarm or protection. Please check the “LED status indicators” in chapter 9 for the detailed faulty definition before any troubleshooting steps. In general, the alarm indication is normal without manual intervention. When the alarm triggering state is removed, CQ16 will automatically return to normal use. Problem determination based on the following points：  Check if the red indicator light illuminates once the battery enters operation;  Whether the buzzer in High-Voltage Control Box on;  Whether the battery system can be communicated with inverter;  Whether the battery can be output voltage or not. Preliminary determination steps Battery system cannot work, when DC Switch on and POWER on, the LED doesn’t light up or flash, please contact the local distributor.  The LED display of High-Voltage Control Box and CQ16 is normal, but it cannot charge and discharge. Observe the display screen of inverter and there is no SOC. Please check whether the CAN communication between High-Voltage Control Box to inverter is well connected. If the connection is good, please replace a CAN communication cable. If the SOC is still not visible on the inverter display screen,; PDF page 35: please contact the local distributor.  After the battery system is powered on, if you can see the alarm information on the LED and inverter display screen at the same time, please contact the local distributor.

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
