10. The inverter is off-grid, and the input power supply of the load equipment needs to be confirmed as the only input device, and do not use in parallel with other input AC power to avoid damage.

Connection Security Information

1. The DC voltage must be matched;
   Each inverter has a nominal voltage, and the selected battery voltage must be consistent with the nominal DC input voltage of the inverter. For example, a 12V inverter must select a 12V battery.

2. The output power of the inverter must be higher than the maximum power of the electrical appliance;
   The maximum power of equipment with large starting energy requirements, such as motors and air conditioners, cannot be higher than the output power of the inverter, and an additional power margin is required.

3. The positive and negative poles must be wired correctly;
   The diameter of the connecting wire must be thick enough, and the length of the connecting wire should be minimized.

4. The inverter shell should be properly grounded to avoid personal injury due to leakage.

Installation Safety Instructions

1. Before installation, please read this manual carefully and be familiar with the installation steps.
2. Be very careful when installing the battery. When installing a lead-acid liquid battery, you should wear protective glasses. Once you come into contact with the battery acid, please rinse it with clean water in time.
3. Avoid placing metal objects near the battery to prevent short circuits of the battery.
4. Acid gas may be generated when the battery is charged, make sure the surrounding environment is well-ventilated.
5. When installing the cabinet, be sure to leave enough space around the inverter for heat dissipation; do not place the inverter and the lead-acid liquid battery together.
6. False connection points and corroded wires can cause extreme heat to melt wire insulation, burn surrounding materials, and even cause fire, so make sure that the connectors are tightened, and the wires are fixed by cable ties to avoid loose connectors caused by shaking of the wires during mobile applications.
7. When installing outdoors, avoid direct sunlight and rainwater infiltration.
8. After the power switch is turned off, there is still high voltage inside the inverter, please do not open or touch the internal components, and related operations can only be performed after the capacitor is fully discharged.
9. Please do not install the inverter in harsh environments such as damp, greasy, flammable, explosive, or a large amount of dust.
10. It is forbidden to reverse the polarity of the battery input terminal of this product, otherwise, it is easy to damage the equipment or cause unpredictable dangers.
11. The AC output is a high voltage, please do not touch the wiring.
12. When the fan is working, do not touch it to avoid injury.

Installation and Wiring

Installation Steps

• Step 1: Read the user manual carefully.
• Step 2: Determine the installation position and heat dissipation space.
• Determine the installation position (wall-mounted or horizontal installation mode can be used).
• When installing the inverter, ensure that sufficient space is available and the inverter is removed
• At least 200mm (7.9in) space should be left between the tuyere and the intake for air circulation.
• If installed in a closed container, ensure that heat dissipation can be dissipated through the container; otherwise, reduce the amount of heat used.
• Step 3: Connect cables

1. The AC device shall be determined according to the continuous output power of the inverter, but the impact power of the AC device. Do not exceed the instantaneous impact power of the inverter. Otherwise, the inverter may be damaged.
2. Before wiring, set the inverter switch to OFF state.
3. During the wiring process, do not close the circuit breaker or safety, and confirm the lead connection of the electrodes of each component.
4. The battery end needs to be installed with insurance, which is selected according to the inverter input rated current of 2-2.5 times.
5. Ensure that the safe position is not more than 150mm away from the battery.
6. The input has no reverse connection protection. Before connecting the battery cable, ensure that the positive and negative terminals are correctly connected.

FAQ

Q: What should I do if the inverter shows an overload alarm?

A: If the inverter displays an overload alarm, immediately disconnect excessive loads to prevent damage to the equipment.

Q: Can I install the inverter outdoors?

A: The inverter should be installed indoors or in a protected environment to ensure proper operation and longevity.

Q1: When I have some problems in the process of using the inverter, what information can I provide to BougeRV to provide me with technical support faster and better?

A1: Send the following information to the email， ①The connection method of the inverter and battery. ②The voltage and battery type of the battery. ③The display data/app data of the inverter. ④Connection from battery to inverter and inverter to the loads. If the above information can be provided with pictures or videos, BougeRV can provide you with technical support faster.

Q2: Can I use the inverter with a 24 V system?

A2: No. This model can only work with a 12V battery system.

Q3: Can I use this inverter to charge my batteries?

A3: No. The BougeRV 12VDC to 120VAC inverter can only convert DC power to AC power. Please check the BougeRV Pure Sine Wave Inverter Charger.

Q4: How to check the power consumption of this inverter?

A4: This inverter has a built-in Bluetooth module, and parameters can be set and viewed on the mobile APP.

Q5: Why does the inverter suddenly disconnect during work?

A5: 1. The battery voltage is low, start the over-discharge protection, and it can work normally after recharging the battery; 2. Battery overcurrent. Most batteries are discharged at 1C(1C discharge refers to:The max discharge current of a 100AH battery is 100A, and the max discharge current of a 50AH battery is 50A.), and a 1500W electrical appliance connected to a 2000W inverter connected to 12V 100AH will cause overcurrent. Because after connecting a 1500W electrical appliance, the inverter needs to get 500W/12.8V=117.19A>100A from the battery. In this case, the battery will start protection and disconnect from other devices. Connecting batteries in parallel to increase the current can solve this problem. 3. The power of the electrical appliance is greater than the rated output power of the inverter. For example, using the 2000W inverter to carry a 2500W high-power electrical appliance cannot work. At the same time, the inverter can withstand a maximum instantaneous impact power of 4000W. This means that even if the rated power of the electrical appliance is less than 2000W, excessive instantaneous power will cause abnormal operation and even damage the inverter.
