Hybrid Solar Inverter Mppt 48V 3Kw Single Phase On Off Grid Inverters

Photovoltaic inverters (PV inverters or solar inverters) can convert the variable DC voltage generated by photovoltaic (PV) solar panels into mains frequency AC inverters, which can be fed back to commercial transmission systems or used for off-grid power grids. Photovoltaic inverters are one of the important system balances (BOS) in photovoltaic array systems, and can be used in conjunction with general AC powered equipment. Solar inverters have special functions in conjunction with photovoltaic arrays, such as maximum power point tracking and islanding protection.

Products Description

1. Introduction to photovoltaic inverters

Photovoltaic inverter is a device that converts direct current (DC) generated by photovoltaic solar panels into alternating current (AC). In the process of constructing and operating photovoltaic power plants, the inverter in electrical equipment plays a very important role. Like photovoltaic power generation system technology, it continuously improves operational efficiency and conversion power, and combines with photovoltaic modules and other power generation equipment to form the most efficient photovoltaic system.

Usually, the process of converting DC electrical energy into AC electrical energy is called inverter, the circuit that completes the inverter function is called inverter circuit, and the device that implements the inverter process is called inverter equipment or inverter.

Inverters, also known as power regulators, can be divided into two types based on their use in photovoltaic power generation systems: independent power supply and grid connected. There are various types of inverters, so special attention should be paid when selecting the model and capacity. Especially in solar power generation systems, the efficiency of photovoltaic inverters is an important factor determining the capacity of solar cells and battery capacity.

2. Working principle of photovoltaic inverter

1) DC input: The DC input of the photovoltaic inverter is the direct current generated by the solar panel. These solar panels are typically composed of multiple solar cells, each generating a certain voltage and current.

2) Maximum Power Point Tracking (MPPT): The photovoltaic inverter is equipped with a Maximum Power Point Tracking (MPPT) controller, which is used to monitor the output voltage and current of the solar panel in real-time, and adjust their operating points to obtain maximum power output.

3) Boost circuit: The direct current of the solar panel enters the boost circuit after passing through the MPPT controller. The boost circuit adjusts the voltage and current to meet the requirements of the internal circuit of the photovoltaic inverter.

4) Inverter: The direct current passing through the boost circuit enters the inverter. The inverter converts direct current into standardized alternating current by using AC switching devices (usually MOSFETs or IGBTs). At the same time, the inverter also adjusts the phase, frequency, and voltage according to the requirements of the power grid.

5) Network connection: The AC power output from the inverter can be connected to the power grid to provide electricity for household, industrial, or commercial use. The inverter ensures that its output is synchronized with the grid and meets the voltage, frequency, and power requirements of the grid.

6) Control and protection: The photovoltaic inverter is also equipped with various control and protection functions, such as temperature monitoring, short circuit protection, overload protection, etc. These functions focus on ensuring the safe operation of photovoltaic inverters and improving the reliability and stability of the system.

Overall, inverters not only have direct to AC conversion functions, but also have the function of maximizing the performance of solar cells and system fault protection. In summary, there are automatic operation and shutdown functions, maximum power tracking control function, anti separate operation function (for grid connected systems), automatic voltage adjustment function (for grid connected systems), DC detection function (for grid connected systems), and DC grounding detection function (for grid connected systems).
