11 features you should know about Deye 50KW

Founded in 2007, Deye has established itself as a leading provider of energy solutions through superior product quality and exceptional customer service. To date, Deye has distributed more than one million hybrid inverters, demonstrating its unwavering commitment to advancing renewable energy solutions globally.

Deye's three-phase hybrid inverter series presents a comprehensive solution designed to meet the diverse power needs of residential, commercial and industrial consumers. Among all products, Deye's 50 kW three-phase hybrid inverter has several key advantages that differentiate it in the market.

800V maximum battery for higher efficiency: Deye's 50 kW three-phase hybrid inverter features lithium-ion batteries with a maximum voltage of 800V (battery voltage range is 160-800V). This higher voltage not only improves power conversion efficiency, but also contributes to longer battery life. With this advantage, users can expect optimal performance and greater energy savings over time. In addition, paired with lithium-ion batteries, it features increased energy density, enabling extended power supply durations in a compact volume.
100A maximum charge/discharge current: Equipped with two battery inputs, each capable of handling a maximum charge/discharge current of 50A, the inverter ensures efficient energy transfer processes. This design facilitates faster charge and discharge cycles, thus optimizing overall system performance and maximizing energy utilization.
Maximum 36A * 4 MPPTs = more power production: With a maximum of 4 MPP trackers and a maximum operating input current of 36A per MPP, the inverter maximizes power production by efficiently tracking and utilizing the available solar energy. This ensures optimal performance even in varying sunlight conditions, resulting in higher overall energy yields. In addition, the four MPP trackers facilitate flexible PV module configuration.
Maximum of 10 units in parallel and support for multiple batteries in parallel: With support for up to 10 units in parallel for both on-grid and off-grid operations, this inverter offers unmatched scalability for large commercial and industrial scenarios. In addition, it integrates seamlessly with multiple batteries in parallel, such as Deye's flagship product: the BOS-G battery. This versatility allows for easy expansion and adaptation to evolving energy needs.
6 time periods for battery charging/discharging: The inverter has six programmable time periods for battery charging and discharging. This feature is typically used in scenarios where there is a large difference between peak and off-peak electricity prices. This customization capability allows users to align energy storage and usage with specific consumption patterns to optimize energy management and save on their pocketbook.
Grid-to-grid zero-level UPS switching: Equipped with the grid-to-grid zero-level UPS switching function, the inverter ensures uninterrupted power supply. In the event of sudden power outages, it automatically switches to battery power, providing continuous uninterrupted electricity, making it an ideal choice for critical applications where downtime is not an option.
AC coupling for greater flexibility: The inverter uses AC coupling, promoting greater system flexibility. Operating in parallel, the hybrid inverter can be coupled to grid-tied inverters and microinverters without the need for extensive power grids or adjustments. This feature simplifies system expansion and maintenance, offering users greater adaptability to evolving energy demands.
Support for diesel generators for greater energy stability: In addition to storing energy from solar panels, the inverter draws power from diesel generators. Equipped with automatic voltage regulation, it improves the power quality of solar-diesel hybrid systems. In scenarios where solar generation falls short of demand, the seamless switch-over to diesel generators ensures an uninterrupted power supply, facilitating continuous electricity generation.
Three-phase 100% unbalanced output: Each phase The SUN-29.9-50K-SG01HP3 series features three-phase 100% unbalanced output. This function has better performance than other brands, as most other brands cannot achieve 100% unbalanced three-phase output on each phase. It can support single-phase and three-phase load application scenarios simultaneously.
Real-time monitoring and online operation and maintenance: The device supports WIFI module, which ensures that it can be operated by mobile equipment. The device can use WIFI modules and RS485 communication terminal port for remote monitoring and to ensure the solar power system is working normally. Real-time monitoring can transfer alarm information and inverter maintenance operation records, which can be used by after-sales personnel.
High-voltage BOS-G battery series: Deye's SUN-29.9-50K-SG01HP3 series is compatible with the BOS-G series of high-voltage lithium batteries, offering safe and reliable performance. These batteries, with capacities up to 61.44kWh, feature an embedded design and flexible connection methods. In addition, they ensure system stability and safety with advanced protection features. Deye has pioneered the development of industrial and commercial energy storage products with 50kW of power, being recognized by PV Magazine as the Best Inverter of 2023.
