This document describes the NBZ Pure Sine Wave Inverter, a device designed to convert DC power from a battery into AC power suitable for various loads. It functions as a second energy AC power supply, offering a reliable alternative to the main power grid.
The NBZ Pure Sine Wave Inverter utilizes advanced sine wave modulation technology to produce an output waveform identical to that of the mains (power grid). This ensures strong shock resistance and a super-high output capacity, making it compatible with a wide range of electrical appliances. The inverter takes DC 12V, 24V, or 48V voltage from a battery and converts it into AC 110V or 220V voltage to power connected loads.
The core working principle involves high-frequency DC/AC conversion. The low-voltage direct current from the battery is first inverted into high-frequency low-voltage alternating current. This is then rectified into a high-voltage direct current of approximately 300V after being boosted by a high-frequency transformer and filtered. Finally, a power frequency inverter circuit converts this into 220V power frequency alternating current for the loads. The use of high-frequency core materials contributes to the inverter's small size, light weight, and improved power density. This design also results in low no-load loss and high conversion efficiency, often exceeding 90%.
The inverter is equipped with several protection functions to ensure safe and reliable operation. These include input undervoltage protection, which automatically turns off the AC output and issues an alarm when the battery voltage drops below a set threshold, indicating the need for charging. Input overvoltage protection similarly activates when the battery voltage is too high, turning off the AC output and sounding an alarm. Short circuit protection automatically cuts off the output power supply in the event of a short circuit at the AC output end. Input protection with opposite polarity is also integrated, where a fuse will burn out to protect the inverter if the battery cable is connected in reverse. Overheating protection is triggered if the internal temperature exceeds 65°C ± 5°C, causing the AC output to turn off and an alarm to sound; the inverter can resume normal operation after about 15 minutes of cooling.
The NBZ Pure Sine Wave Inverter is widely applicable in various systems, including solar power generation, new energy storage, household appliances, and industrial automation equipment. It can power common household appliances such as TVs, refrigerators, induction cookers, electric fans, microwave ovens, and air conditioners.
Key product features include pure sine wave output and a soft start function, which helps protect connected appliances. The input and output are completely isolated, enhancing safety. The inverter is designed to be compact and highly efficient. It incorporates a microprocessor for intelligent control and electronic intelligent temperature-controlled air cooling, which ensures good heat dissipation and energy saving. In addition to the aforementioned protections, it also features battery energy shortage and over-temperature alarm functions.
For optimal performance and safety, specific normal operation conditions must be met. The ambient temperature should range from -10°C to +40°C, with relative air humidity below 85% (at 20°C ± 5°C). The installation altitude should not exceed 1000m. The inverter must be operated indoors, free from vibration, shock, conductive or explosive dust, or corrosive gases. It must be installed in a dry place, away from rain, spray, or splash water, and its safety vents must not be blocked to prevent overheating. For operation outside the specified temperature range (-10°C to +40°C), users should consult the manufacturer.
When connecting the inverter, it is crucial to turn the inverter switch to the OFF position before connecting it to the battery or any electrical equipment. The black wire from the battery should connect to the negative terminal of the inverter, and the red wire to the positive terminal. Reversing the polarity will burn the fuse and potentially damage the inverter. The cabinet grounding screw must be well and reliably grounded.
The startup sequence involves first turning on the inverter switch, followed by turning on the equipment switch. The stop sequence is the reverse: first turn off the equipment, then turn off the inverter switch. Plugging the power cord of the AC appliance into the AC power outlet and turning on the inverter switch should result in the red and green LED indicators lighting up for 3-5 seconds. The red LED will then turn off, and the green LED will remain on, indicating normal operation, provided the output load does not exceed the inverter's rated power.
The inverter includes a USB port for providing 5V DC power to external USB devices, such as charging phones. This output is permanently switched on when the inverter is connected to the input voltage. However, it is important to note that the USB port is not for data transfer; connecting data transmission cables could damage data storage devices.
Battery selection is critical, as it directly impacts the inverter's runtime. The battery capacity (Ah) and voltage (V) should be determined based on the inverter's load power (W). For example, a 150Ah 12V battery with a 600W load would provide approximately 3 hours of backup time. This is a theoretical value, and actual times may vary. To prevent excessive battery discharge, it is recommended to charge the battery before the inverter reaches its low voltage off point, especially under light load conditions.
For battery wiring, series connections increase the total output voltage of the battery pack, with each battery connected in series to match the inverter's DC input requirements. The total capacity remains unchanged in a series connection. Parallel connections, on the other hand, increase the total running time of the AC load, as the total capacity becomes the sum of individual battery capacities, while the voltage remains unchanged.
The inverter is designed with integrated electronic circuits and can automatically reset after protection events. In the event of a reverse polarity connection, an internal fuse may burn out. A spare fuse is typically included with the inverter and can be replaced by maintenance personnel by opening the bottom of the unit.
For safety during installation, it is recommended to connect a DC fuse or circuit breaker with a rated current in series on the positive line of the battery. This acts as short-circuit protection and an input switch. The fuse or circuit breaker should be capable of withstanding the current generated by the battery, with appropriate current ratings (e.g., DC150A for 1000VA, DC200A for 1500VA).
In case of any abnormality or fault, users are advised not to open the product without permission to prevent electric shock, as internal capacitors can retain electrical energy even after power supplies are disconnected. Any faulty product should be sent to professional maintenance personnel.
When scrapping the inverter, it is important to note that electrolytic capacitors in the main circuit and on the printed panel can explode during burning. Plastic parts, such as front panels, will generate toxic gas when burned. Therefore, the inverter should be disposed of as industrial waste.
Troubleshooting common faults is outlined in the manual. If the inverter does not work, checking for poor contact in the input wire is the first step. If the output voltage is too low, verify if the load power exceeds the rated power. A low voltage alarm indicates either low battery voltage or improper wiring. Overheating protection requires placing the inverter in a ventilated area for cooling. If the inverter fails to start, check for reverse polarity connections and a burnt fuse. If the inverter does not operate, ensure the power switch is on and that the fuse and battery cable are firmly connected.
The manual also provides a table of common faults and their solutions, covering issues like no AC output, intermittent AC output, short battery backup time, low battery alarm, and TV interference. Solutions range from charging or replacing the battery, reducing the load, replacing fuses, and checking wiring connections to adjusting battery voltage levels and increasing the distance between the device and the inverter.
The inverter should be de-energized during installation, wiring, maintenance, and troubleshooting, and these operations should only be performed by professional electricians or technicians to avoid electric shock or damage.
The product package includes the inverter, a user manual, DC input wires, and spare fuses. The manual provides detailed diagrams for various inverter power ratings (300W-600W, 1000W-2000W, 3000W-5000W) showing the layout of indicators, switches, sockets, and terminals. It also illustrates battery wiring methods for both series and parallel connections, as well as schematic diagrams for 12V and 24V inverter wiring.
