Theory
Inverter is a device that converts direct current into alternating current. It is the core component of solar photovoltaic power generation system. According to the product design, it can be divided into special sine wave inverter for solar photovoltaic power generation and economical solar photovoltaic power generation control inverter.Performance characteristics of special sine wave inverter for solar photovoltaic power generation are as follows: DSP Chip control, intelligent power module assembly, pure sine wave output, output voltage stabilization and frequency stabilization, as well as various protection functions such as over-voltage, under-voltage, overload, short circuit and reverse connection of input polarity. Its inverter efficiency is not less than 85%, with AC bypass function and excellent input / output performance EMI/EMC Indicators, can be equipped RS-232/485 Interface, high reliability.
Application/Usage
1. In Africa, work can only be started at night because it is too hot during the day. The small inverter is light and space-saving, which solves a big problem for busy farming and site construction.
2. When there is a sudden power failure in restaurants and outdoor activities, it will not affect our normal progress.
3. When going to remote areas or disaster areas for emergency rescue, it can not only help lighting, but also drive most medical devices, which is very convenient.
4. At ordinary times, you can have a barbecue on the roof or in the field at night, and you don't need to connect the power supply. You can directly bring this inverter to meet many needs. For example, small refrigerators, mobile phones, lighting, etc.
Advantage/Selling points
1. High reliability
Due to the dual conversion design, the inverter output has frequency tracking, noise filtering and low distortion
2. High adaptability
Wide input frequency range to realize stable operation of solar generator
3. High and optimal performance of battery
Intelligent battery management technology ensures longer battery life. Advanced constant voltage charging technology can activate the battery to the greatest extent and save cost.
4. Comprehensive and reliable protection
The power on test function can avoid faults and unnecessary hazards.
5. Overall automatic protection and alarm, such as output overload protection.
Operation method
At the beginning, it is the preparation before wiring. Before the electrical connection of photovoltaic inverter, it is necessary to ensure that the DC switch of inverter is in "off" state and disconnect the air switch at AC side. Otherwise, the high voltage of the inverter may cause the life danger of counterfeiters. Then, each inverter shall be installed independently - an AC circuit breaker. It is forbidden to share multiple inverters. It is forbidden to connect load between inverter and circuit breaker. It is forbidden to use single core wire at the output end of the inverter.It should be noted that the protective ground wire PE should also be connected. At one point, the protective ground wire PE should be connected. The inverter and the grounding bar should be connected through the protective ground wire PE to achieve the purpose of grounding protection.
Attention
As an indispensable daily necessities, we all have a natural fear of electricity more or less. As an electronic product, photovoltaic inverter is composed of multiple devices. When it is connected to the grid for power generation, it is often hundreds of volts, so it must not be careless in operation, otherwise there may be potential safety hazards.
1. It is strictly prohibited to operate and disassemble the inverter at will
The inverter operators shall receive systematic training and be qualified before operating the inverter. Non professional operators are not allowed to operate without authorization. It is forbidden to disassemble, repair and transform the inverter by themselves.
2. Do not damage power wires and cables
Do not step on, screw or pull the cable. Cable damage will cause electric shock, short circuit and fire. In case of burning odor, abnormal sound, abnormal heating, smoking and other abnormal phenomena, close the circuit breaker immediately and contact the inverter manufacturer immediately, otherwise there are dangers such as electric shock and fire.
3. Please place fire extinguishers in the place where the inverter is installed
4. We solemnly remind you that you must read and understand the user manual provided by the photovoltaic inverter manufacturer and be familiar with the relevant safety symbols before installing and commissioning the equipment.

FAQ
Q1. What is an inverter?
A: The inverter converts DC energy into current. It consists of inverter bridge, control logic and filter circuit.
Q2. What are the output wave-forms of the inverter?
A: Pure sine wave inverter is divided into pure sine wave inverter and modified sine wave inverter. Pure sine wave inverter can provide high-quality AC power supply and carry various loads, but it has high technical requirements and high cost. The modified sine wave inverter load does not carry inductive load, but the price is moderate.
Q3. How is your service?
A: Customer centered service, improve its service portfolio according to the needs of each customer, because we believe that customer satisfaction is the driving force for the development of the company. Our skilled R & D engineers and customer support team are ready to provide customers with a full range of services.
Q 4. Is the quality of your products really up to standard?
A: You have no doubt about this. We pay great attention to quality, "manufacturing reliable products" is the core business foundation of our company. Suns only provides reliable solar products.
Q 5. Why does the battery suddenly stop working and the indicator light doesn't light up?
A: 1. Please check whether the battery is faulty and replace it if necessary.
2. Check whether the positive and negative electrodes are connected correctly.
3. Check whether the cable is loose. If it is loose, tighten it immediately.
Q6. Why is the service time too short after being fully charged?
A: 1. The power consumption of electrical appliances is greater than the rated load of inverter.
2. The battery is faulty or damaged.
3. Poor battery charging.
4. The current drops when passing through the cable.
