On Grid Solar Inverters
The grid tie inverter converts the DC power generated by solar panels into AC power for the load. The excess power can be fed back to the power grid company to get a margin. When the solar intensity decreases and the electricity generated by the solar panels is not enough to support the load, the grid power will also supply power to the load.
At JMHPOWER, we have solar grid tie inverters from world-renowned brands, such as Growatt, Solis, Deye, MEGAREVO, etc., and have grid-connected certification licenses that comply with most countries in Europe, Asia, America, etc., such as CE, UL, FCC, SAA, ROSH, CQC, UN38.3, IEC, EN, VDE, NRS, UNE, CEI 0-21, and so on.
The power of grid tie inverters ranges from 1kw to 200kw, including single phase inverters and three phase inverters. Single phase inverters are mainly used in home solar systems and small commercial solar systems. Three phase inverters are mainly used in industrial and commercial solar power systems and large power stations.
In addition, on grid inverters are easy to install because they do not require batteries. Small on grid solar power systems only require basic electrician knowledge to install.

The Working Principle of On Grid Solar Inverter
The working principle of an on grid solar inverter is to convert the DC power generated by solar panels into AC power that matches the electrical grid’s voltage and frequency. It uses power electronics to achieve this transformation and synchronizes the AC output phase with the grid for smooth power transfer. Additionally, the on grid solar inverter monitors grid conditions and can disconnect if necessary to ensure safety and stability.
Key Functions of On Grid Inverters
As an important part of the solar power generation system, the grid tied inverter increases the utilization rate of green energy.
Understanding its characteristics and functions can make the solar system more standardized, reasonable, safer and maximized. Improve the utilization rate of green and environmentally friendly energy.
The on grid inverter accurately tracks the maximum power point of the solar panel through intelligent algorithms based on the voltage and current generated by the solar panel, ensuring that it can produce maximum power output under different light intensities. Improve the efficiency of solar power systems.
The AC output frequency and voltage of the grid-connected inverter need to be consistent with the grid. The inverter will also monitor changes in grid data in real time and then make adjustments to ensure the consistency between the inverter and the grid.
When the grid is out of power and requires maintenance, the inverter will cut off the connection with the grid within 4ms to ensure the safety of maintenance personnel. After the grid returns to normal, the inverter will automatically connect to the grid.
The bidirectional current data of the inverter and the power grid can be counted through the smart meter. There is also WiFi or GPRS that can monitor the working data of the solar system, and the data can be viewed in real time through mobile phones and computers.
How to Choose a Suitable On Grid Inverter?
- Match Power Capacity: Choose an on grid solar inverter with a power rating that matches or slightly exceeds your solar array’s maximum output.
- Ensure Compatibility: Verify the on grid solar inverter is compatible with your solar panels’ voltage and the grid’s requirements.
- Prioritize Efficiency: Select an on grid solar inverter with high conversion efficiency to maximize energy output.
On Grid Solar Inverters FAQ
On grid solar inverters are not compatible with all types of solar panels. They need to match the specific voltage and current characteristics of the solar panels. It’s important to check the solar inverter’s technical specifications to ensure compatibility with your solar panel type and system configuration.
Many on grid solar inverters are designed for outdoor installation, featuring weather resistant enclosures to protect against environmental conditions. However, it’s important to ensure the solar inverter’s IP (Ingress Protection) rating matches the specific outdoor conditions of your location. Proper installation and protection from extreme weather are also crucial for long term reliability.
To ensure electrical safety during the installation of an on grid solar inverter, always follow the manufacturer’s installation guidelines and local electrical codes. Use proper personal protective equipment (PPE) such as gloves and safety glasses, and make sure the power supply is disconnected before starting any work. Additionally, ensure all connections are secure and correctly insulated to prevent electrical shocks and short circuits.
An on grid solar inverter should be installed in a location that is cool, dry, and well ventilated to ensure optimal performance and longevity. It is typically placed near the main electrical panel or close to the solar array to minimize cable length and voltage drop. Additionally, it should be easily accessible for maintenance and monitoring while being protected from direct sunlight and harsh weather conditions if installed outdoors.
