Advantages of Grid-Tied Systems.

1. Save more money with net metering

Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries.

2. The utility grid is a virtual battery

The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity goes to waste with conventional battery systems.

High output

• The highest efficiency 98.2%
• Real-time and accurate MPPT algorithm, MPPT efficiency greater than 99.5% to ensure maximum return
• Wide operating voltage range: from 90V to 580V, compatible with various specifications of photovoltaic arrays
• Independent dual MPPT tracking for better adaptability to various rooftop power station designs
• Transformerless inverter topology is used to achieve higher inverter efficiency

Flexible and economical system solutions

• LCD screen plus combination buttons for easy viewing of inverter status information, communication connections, and system configuration
• RS485 and external Wi-Fi/GPRS (optional): System monitoring configuration is more flexible
• Mobile APP real-time monitoring is more convenient
• Built-in anti-backflow function (optional)
• Built-in sound and light alarm function

Low maintenance costs

• Transformerless design, Higher efficiency, smaller size, lighter weight
• All-aluminum stainless steel case, natural heat dissipation, enhanced corrosion protection, extended service life
• IP65 protection level, freedom of installation location
• Photovoltaic connector for easier installation and maintenance
• Flexible and mature monitoring solutions

Smart Grid Management

• Reactive power adjustable function
• When the power grid is over-frequency, automatic load shedding
• Remote active limit function
