GNE New Energy products can be deployed in residential, commercial and large-scale PV systems. GNE solar power optimizer provides design flexibility, module-level performance measurement, control and optimum energy harvest, cost efficient maintenance for solar arrays of all sizes.

Key Technology

he key technology of GNE power optimizer is comprehensive combination of high efficiency electronic converting technique, express DSP and controlling technology, advanced semiconductor integrated circuit technology, data acquisition and monitoring technology, network communication and data processing technology etc. Base on those technologies, it could optimize the power output of each PV module by independent module level MPPT and consequently achieve the maximum power generation of the entire PV system.

GNE power optimizers are DC-DC converters connected to PV modules in order to maximize the energy harvested from each module. It can achieve module-level maximum power point tracking (MPPT) and plays a critical part in the whole power system.Each power optimizer transmits its module's performance data to a shared data communicator. The signals from the distributed power optimizers and inverters are received by the data communicator and can be used for remote monitoring and maintenance.The power optimizers have been widely used in the grid-tied PV power system applications from pilot power sites to mega solar parks.

Relying on the comprehensive application of high efficient electronic converting technology, express DSP and controlling technology, advanced semiconductor integrated circuit technology, data acquisition and monitoring technology, network communication and data processing technology, etc., GNE New Energy features the solar power optimizer with high efficiency, reliability, flexibility and lower cost.

The GNE optimization solution enables solar arrays to harvest more energy, and provides distinct advantages in design, installation and operation.

Working Principle

• 1. Solar power optimizer connects with PV module directly without additional panel wiring. By using a smart algorithm for GNE solar power optimizers, each module constantly performs at its maximum power point, therefore maximizes the energy generated per module in any light condition, and consequently the total solar energy is produced. PV modules perform individually to eliminate the power loss caused by module mismatching, aging, shading, coverings and any other factors.
• 2. GNE solar power optimizers are connected with each other in series to achieve the proper bus voltage required by the grid-tied inverter. This work facilitates the optimizer’s implementation within a system as each optimizer outputs low voltage. Consequently, higher efficiency, increased reliability and lower cost could be possible.
• 3. Due to PV strings formed by the modules and optimizers connected in parallel, it can eliminate the quantity limitation of each string and keep the PV arrays more flexible in installation.
• 4. The output power from all optimizers is aggregated at the DC side of grid-tied inverter and converted to AC
• 5. Solar Power Optimizer supports the function of data acquisition and wireless data transcribing, gathering the information of output voltage, current and power in real-time. It operates module-level data acquisition and performance measurement to achieve higher reliability, rapid fault detection automatic alerts localized on a virtual site map for accurate troubleshooting.
• 6. The collected data of GNE solar Power Optimizer is transmitted wirelessly via GNE Data Acquisition Unit to the GNE Data Aggregation Device. DAU sends the data via Ethernet to Cloud Data Center (GNE Monitoring Server).
• 7. Cloud Data Center (GNE Monitoring Server) stores and analyzes the working information of PV modules, deliveries early warning of abnormal data/status to the data acquisition unit via Internet. Then, the data acquisition unit would operate feedback information to solar power optimizer. Simultaneously, users or operators would receive notification such as SMS and Email from Cloud Data Center once serious failure taken place.
• 8. This monitoring system allows module-level visibility and provides insight into the performance of any system. User can login the web-based monitoring system, measure current energy production and status of the entire solar system. Meanwhile, user can access the historical data to analyze the performance of solar system.
