Solar Power Mini-Inverter solves partial-shading problems.

Press Release Summary:

Featuring 4 DC input channels, CyboInverter can connect to as many as 4 solar panels using standard connectors and performs Maximum Power Point Tracking (MPPT) for each connected panel. Ability to connect to panels with different sizes or brands, oriented in different directions or angles, promotes installation flexibility, and multiple CyboInverters can daisy chain with AC cables connecting to power grid.

CyboEnergy Unveils CyboInverter, the World's First Solar Power Mini-Inverter at Intersolar North America

SAN FRANCISCO -- CyboEnergy, a subsidiary of CyboSoft (Rancho Cordova, California), announced today that it is showing its patent-pending CyboInverter, the world's first solar power Mini-Inverter at Intersolar in San Francisco.

In Booth 8242, CyboEnergy is running a live CyboInverter demo. As shown on, each 4-channel CyboInverter can connect to four solar panels using standard connectors. Multiple CyboInverters can daisy chain with AC cables connecting to the power grid. Imagine the ease of installation.

The CyboInverter performs Maximum Power Point Tracking (MPPT) for each connected panel solving partial-shading problems. It can connect to panels with different sizes or brands, oriented in different directions or angles. This "anything goes" design significantly improves scalability, user-friendliness, and ROI.

CyboEnergy CEO Dr. George Cheng said, "A small solar power system on a residential rooftop or backyard can be viewed as a personal power generation plant. CyboInverters allow people to start small and grow with recurring revenue through power generation. As solar system prices come down and electricity prices go up, this scalable approach makes even more sense. Since many states no longer offer incentives, this approach encourages homeowners to make low risk yet affordable investments in personal power plants that can grow. This is a sustainable business model that could reach a critical mass and have a powerful impact on the energy industry."

So, what really is a Mini-Inverter? CyboEnergy gives the definition based on the table at comparing Centralized Inverters, Microinverters, and Mini-Inverters.

A Centralized Inverter connects to all solar panels on a string through one DC input port. It has the lowest inverter per watt cost but has partial-shading problems and complex design and installation requirements. Because Centralized Inverters can handle a large number of panels, they are well suited for large-scale systems.

A Microinverter is mounted on each solar panel and performs MPPT. It solves partial-shading problems and makes installation easy. The Microinverter market is showing a rapid growth. However, since each Microinverter supports only one panel, it is difficult to reduce the inverter per watt cost.

CyboInverter, as the first solar power Mini-Inverter, is designed to include multiple DC input channels that can connect to multiple solar panels and perform MPPT for each channel. This is a more cost-effective approach for inverter design, manufacturing, and installation. For this reason, it can provide the lowest per watt cost for an installed system. CyboInverter's scalable capability makes it ideal for small- to mid-size solar power systems, and potentially suitable for large or even utility-scale projects.
