Overview

A 300W on-grid inverter is a device used in solar power systems to convert the direct current (DC) generated by solar panels into alternating current (AC) that can be used in a home or business and fed back into the electricity grid. A 300W grid tie inverter is an essential component of a solar power system, managing the flow of electricity between the solar panels, the home, and the grid.

Features:

High performance maximum power point tracking (MPPT). This leads to increased efficiency, more energy production, and improved grid stability.
Directly connected to the solar panels (do not need to connect the battery).
AC 0 angle with high precision auto-detection. This helps in reducing stress on the electrical components and extending their lifespan.
Synchronous high-frequency modulation. Operating at high frequencies reduces switching losses, leading to improved overall efficiency in the power conversion process.
Power automatically locked (APL), make the output power more stable, use SPWM directly to make pure sine wave output.
Automatically adapt to different load power factor and automatically shut down when the power output of a fault.

Details:

Aluminium Magnesium Alloy

Its lightweight nature reduces the overall weight of the inverter, making it easier to install and handle. This alloy also has excellent thermal conductivity, aiding in effective heat dissipation and helping maintain optimal operating temperatures for grid tie inverter components. The alloy's high corrosion resistance ensures durability and longevity, even in harsh environmental conditions.

DC Input

DC input in on-grid inverter offers high efficiency. It allows seamless integration with solar panels or other renewable energy sources, converting DC power directly into AC power for grid use. Also can handle a range of DC voltage levels from different renewable sources. Additionally, using DC input simplifies the overall system, as fewer conversion stages are required, lowering costs.

Pure Sine Wave

This consistent power supply reduces noise and interference, improving performance and lifespan of connected devices. Pure sine wave power inverter is also more efficient and generate less heat, contributing to a longer overall system lifespan. Pure sine wave produces a cleaner power signal that is less likely to disrupt nearby electronic equipment, ultimately enhancing overall system reliability.

FAQ

How to select a right solar inverter for PV system?

Solar inverter is an important conversion device of solar photovoltaic system, which can not only convert direct current energy into sinusoidal current synchronized with the frequency and phase of the power grid, but also feed the power into the grid. It can also protect the safety of the whole power station, so the selection of a good solar inverter plays an important role in the photovoltaic power station.

Efficiency. The efficiency represents the power loss of solar pv inverter. The efficiency of the inverter has an important impact on the photovoltaic power generation system to improve the effective power generation and reduce the cost of power generation. Therefore, the selection of solar inverter should be compared as far as possible and the products with higher overall efficiency should be selected.
Rated output power. The rated output power represents the power supply capacity of the solar inverter to the load. Solar inverter with high rated output power can carry more power load. When choosing solar inverter, we should first consider that it has enough rated power to meet the requirements of the equipment under the maximum load, as well as the expansion of the system and the access of some temporary loads.
Startup performance. The solar inverter should be started reliably under rated load. The high performance solar inverter can start at full load for many times without damaging the power switch and other circuits.
Output voltage adjustment performance. The adjustment performance of output voltage represents the voltage stabilizing ability of output voltage of solar inverter. Generally, photovoltaic inverter products give the percentage of fluctuation deviation of output voltage of the solar inverter when the dc input voltage changes in the allowable fluctuation range, which is usually called voltage adjustment rate.

It would be nice if the casing were more rugged for outdoor use.

I used this 300W grid tie inverter to connect a small panel array to my home system, and it synced up with the grid smoothly. MPPT tracking works well. It’s great for light-duty setups, but don’t expect it to handle high-demand appliances.
