This design facilitates quicker charging and discharging cycles, thereby optimizing overall system performance and maximizing energy utilization.

3. Max. 36A * 4 MPPTs = more energy production

Featuring a maximum of 4 MPP trackers and a maximum operating input current of 36A per MPPT, the inverter maximizes energy 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. Also, the four MPP trackers make it easy and flexible for the configuration of PV modules.

4. Max. 10 pcs parallel & Support multiple batteries parallel

With support for up to 10 parallel units for both on-grid and off-grid operations, this inverter offers unmatched scalability for large C&I scenarios. Additionally, it seamlessly integrates with multiple batteries in parallel, such as Deye’s star product – BOS-G battery. This versatility allows for easy expansion and adaptation to evolving energy needs.

5. 6 time periods for battery charging/discharging

The inverter features six programmable time periods for battery charging and discharging. This feature is usually used in scenarios where there is a large difference between peak and valley electricity prices. This customization capability enables users to align energy storage and usage with specific consumption patterns and thus optimizes energy management and saving your pocket.

6. UPS Level Grid-to-Off-Grid Switching

Equipped with the UPS Level Grid-to-Off-Grid switching function, the inverter ensures an uninterrupted power supply. In the event of sudden grid outages, it automatically switches to battery power, providing continuous electricity without disruption, making it an ideal choice for critical applications where downtime is not an option.

7. AC Coupling for Enhanced Flexibility

The inverter employs AC coupling, fostering greater system flexibility. Operating in parallel, the hybrid inverter can be AC coupling with grid-tied inverter and Micro Inverter without the need for extensive system redesign or adjustments. This feature streamlines system expansion and maintenance, offering users greater adaptability to evolving energy demands.

8. Support Diesel Generators for Improved Power Stability

In addition to storing energy from solar panels, the inverter gets energy from diesel generators. Equipped with automatic voltage regulation, it enhances the power quality of hybrid solar-diesel systems. In scenarios where solar generation falls short of demand, seamless switching to diesel generators ensures uninterrupted power supply, facilitating continuous electricity generation.

9. 100% Three Phase Unbalanced Output, Each Phase

The SUN-29.9-50K-SG01HP3 series features 100% three-phase unbalanced output. This function has better performance than other brands, for most of the other brands can’t realize 100% three-phase unbalanced output each phase. It can support single-phase and three-phase load application scenarios simultaneously.

10. Real-Time Monitoring Online O&M

The device is compatible with a WIFI module, ensuring it can be operated by mobile equipment. The device can use WIFI modules and an RS485 communication terminal port for remote monitoring and to ensure the solar energy system is running normally. The real-time monitoring can transfer alarm information and inverter maintenance operation records, which can be used by after-sales staff.

11. High-voltage BOS-G battery series

The SUN-29.9-50K-SG01HP3 series can be compatible with BOS-G series high-voltage Lithium Battery, with a single module nominal voltage of 51.2V, single module energy of 5.12kWh, single module capacity of 100Ah. The BOS-G series features a 19-inch standard embedded design, safety and reliable performance, and intelligent BMS, etc.

The battery has a capacity range from 20.48kWh to 61.44kWh, composed of 4-12 battery modules, respectively. Both these embedded designed modules and plug-and-play wire connection methods promise flexible installation and maintenance.

Meanwhile, the BOS-G series is stable and safe for its protection functions including over-discharge&charge, over-current and over-temperature protection. The system can manage the charge and discharge state and balance the current and voltage of each cell automatically.

Deye leads the industry by being the first to develop industrial and commercial energy storage products with 50kW of power. Deye SUN-29.9-50K-SG01HP3 inverter series was honored as the Best Inverter of 2023 by PV Magazine, a leading global solar and storage media platform with regional insights.

“Operating at a high voltage minimizes losses and these types of batteries perform better in terms of capacity and density, For C&l applications, you want to look out for this feature.” said Samuel LeFloch, a senior jury of PV magazine.
