Solis Three Phase String Inverters
Solis three phase solar inverters range from 3kw to 215kw, which can not only meet the needs of home solar systems, but also be widely used in industrial and commercial solar panel systems and large scale grid connected power stations.
The inverter supports 3 phase unbalanced loads, triple peak power, pure sine wave output, and a wide input voltage anti-interference range, which can adapt to harsh power grid environments. At the same time, the inverter also has complete protection mechanisms, such as overvoltage, overload, overheating, short circuit, overcurrent, and other protection functions.

Differences Between Three Phase and Single Phase String Inverters
- Output Voltage and Grid Compatibility:Three phase string inverters output three phase AC voltage, suitable for industrial and commercial grids, while single phase string inverters provide single phase AC voltage, designed for residential and smaller applications.
- Power Capacity and Efficiency:Three phase string inverters are typically higher in power capacity and more efficient under high load conditions, making them ideal for large scale installations, whereas single phase string inverters are better suited for lower power needs and smaller setups.
- Harmonic Distortion and Complexity:Three phase string inverters generally produce lower harmonic distortion and are more complex in design, while single phase string inverters are simpler and may have slightly higher harmonic distortion.
- Cost and Application Scenarios:Three phase string inverters are more expensive and commonly used in large solar farms and industrial facilities, whereas single phase string inverters are more cost effective and widely used in residential and small commercial installations.
Does the Efficiency of Three Phase String Inverters Decrease Over Time?
The efficiency of three phase string inverters is relatively stable under normal operating conditions and does not significantly decrease with time. However, if a three phase string inverter is exposed to high temperatures, high humidity, or dusty environments for extended periods, it may lead to poor heat dissipation or aging of internal components, thereby affecting its efficiency.
Regular maintenance, such as dust removal and inspection of the cooling system, can effectively extend the inverter’s lifespan and maintain its efficiency.
Three Phase String Inverters FAQ
The three phase string inverter is a device used to convert the direct current (DC) generated by solar panels into alternating current (AC). Its output is three phase AC, which enables more efficient power transmission and provides higher quality power stability. It is typically applied in high power, high stability industrial and commercial applications.
The installation of a three phase string inverter can vary in difficulty depending on the specific model and the installer’s experience. Typically, it requires some electrical knowledge and adherence to safety standards. With proper planning, correct tools, and following the manufacturer’s guidelines, it can be installed efficiently, but it is often recommended to have it done by a professional to ensure safety and optimal performance.
A three phase string inverter generally does not require regular calibration. However, periodic maintenance and inspection are recommended to ensure optimal performance and longevity. This includes checking connections, cleaning components, and verifying system settings to maintain accuracy and efficiency.
The lifespan of a three phase string inverter generally ranges from 10 to 20 years. This duration can be influenced by factors such as operating conditions, maintenance practices, and the quality of the inverter components. Regular maintenance and optimal installation environments can help extend its lifespan.
Three phase string inverters generally produce some level of noise during operation, but it is usually not excessively loud. Modern inverters are designed to minimize noise through advanced cooling systems and efficient circuit design. Proper installation and placement, such as keeping the inverter away from living areas, can further reduce any potential noise impact.
