The DEYE SUN-100K-SG02HP3-EU-GM10 is a powerful 100 kW three-phase high-voltage hybrid inverter engineered for advanced solar PV and energy-storage systems requiring high power, flexible energy management and reliable backup capability.

Combining a solar inverter, battery inverter and intelligent energy-management platform in a single unit, the SUN-100K-SG02HP3-EU-GM10 can manage PV generation, high-voltage lithium battery storage, the utility grid, backup loads, AC-coupled generation and generator input. This makes it an exceptionally versatile solution for high-capacity commercial and professional energy-storage installations.

With 10 independent MPPT trackers and up to 20 PV strings, a maximum PV access capacity of 200 kW, two high-voltage battery inputs, 100 kW rated AC power, and up to 250 A continuous AC passthrough from grid to load, the inverter is designed to handle complex, high-power energy systems efficiently.

High-performance 100 kW hybrid energy platform

At the heart of the SUN-100K-SG02HP3-EU-GM10 is a highly efficient three-phase conversion platform with a maximum inverter efficiency of 98.7%, Euro efficiency of 98.1% and an MPPT efficiency above 99%.

The inverter delivers 100,000 W rated AC input/output active power, with maximum AC apparent power of 110,000 VA. For demanding off-grid conditions, it can temporarily supply up to 1.5 times its rated power for 10 seconds, providing additional capability for loads with high starting currents.

10 MPPT trackers and up to 20 PV strings

One of the major advantages of the GM10 version is its exceptionally flexible PV architecture.

The inverter provides:

• 10 independent MPPT trackers
• 2 PV strings per MPPT
• Support for up to 20 PV strings
• 200,000 W maximum PV access power
• 160,000 W maximum PV input power
• 1,000 V maximum PV input voltage
• 180 V start-up voltage
• 150–850 V MPPT operating range
• 650 V rated PV input voltage
• Maximum operating current of 42 A per MPPT
• Maximum short-circuit current of 63 A per MPPT

The large number of independent MPPT channels provides considerable design flexibility where PV arrays have different orientations, inclinations or operating conditions. The manual additionally provides an MPPT Scan function that can periodically perform I-V curve scanning to relocate the maximum power point when shading affects normal MPPT tracking.

High-voltage lithium battery support

The SUN-100K-SG02HP3-EU-GM10 is designed for high-voltage lithium-ion battery systems, helping reduce current and associated conversion losses in high-power installations.

Key battery characteristics include:

• Lithium-ion battery support
• 160–1,000 V battery voltage range
• Two battery inputs
• Up to 100 A + 100 A charging current
• Up to 100 A + 100 A discharging current
• Automatic charging strategy through compatible BMS communication
• Dedicated BMS1 and BMS2 communication interfaces

The inverter can therefore work with two battery systems through its separate battery power and communication interfaces. The manual also describes configurations where battery clusters can be operated in parallel, subject to the appropriate BMS arrangement and Deye's approved battery requirements.

Intelligent Time-of-Use energy management

For installations where electricity prices vary throughout the day, Deye provides advanced programmable battery control.

The inverter supports six programmable time periods for battery charging and discharging, allowing the system to determine when battery energy should be stored, retained or used.

Depending on the selected configuration, this can be used to:

• Charge batteries during low-cost tariff periods
• Discharge during periods of high electricity demand
• Increase solar self-consumption
• Establish different target battery SOC levels during the day
• Permit grid or generator battery charging during selected periods
• Control energy export during specified periods
• Optimize the balance between solar, battery, grid and load consumption

The detailed System TOU functionality is configurable directly through the inverter interface.

Multiple operating modes

The SUN-100K-SG02HP3-EU-GM10 offers considerable flexibility for different system architectures and energy-management strategies.

Supported applications described by Deye include:

On-grid operation
Solar generation can supply loads, charge the battery and, where permitted and configured, export surplus energy to the utility grid.

Off-grid operation
The inverter can supply backup loads from PV and battery storage without an active grid connection.

UPS / backup applications
Critical loads can be connected to the inverter's dedicated LOAD connection for backup operation.

Zero Export to Load
The inverter can restrict its output to the connected backup loads and battery charging.

Zero Export to CT
Using external CTs or a compatible smart meter, the system can supply both backup and home loads while controlling energy flow at the grid connection point.

Selling First
Surplus available energy can be exported to the utility grid where permitted by local regulations and system configuration.

These operating modes allow the installer to tailor the inverter to the requirements of the installation rather than being restricted to a single energy-flow strategy.

AC coupling for existing PV installations

The SUN-100K-SG02HP3-EU-GM10 supports AC coupling, making it possible to integrate compatible existing grid-connected solar generation into a hybrid energy-storage system.

The manual describes AC coupling on either the Grid side or Load side, as well as the use of the multifunctional GEN connection for an external grid-following inverter in suitable configurations.

This capability makes the inverter particularly useful where an existing photovoltaic installation is being upgraded with battery storage rather than completely redesigned.

Generator integration

For installations requiring an additional independent energy source, the Deye inverter incorporates extensive generator integration functionality.

The generator connection can be used to provide AC energy to the system and charge the battery. The inverter also includes a G-Start dry contact that can be used for remote generator start/stop control according to configured battery conditions.

Generator management options described in the manual include battery SOC-based starting and stopping, maximum generator charging current, maximum generator run time, generator downtime and generator peak shaving.

The peak-shaving function allows the inverter to supplement generator output with PV or battery power, helping prevent the generator from exceeding a configured power limit.

Multifunctional GEN / Smart Load port

The GEN connection is more than simply a generator input. Depending on the system configuration, it can serve different functions, including:

• Generator input
• Smart Load output
• On-grid inverter / AC-coupling input

When configured as a Smart Load output, the inverter can automatically switch selected loads according to battery SOC or voltage thresholds, making it possible to direct surplus available energy toward controllable non-critical loads.

Up to 10 inverters in parallel

For installations requiring considerably more capacity, Deye specifies support for up to 10 compatible units operating in parallel in both on-grid and off-grid applications.

The manual describes a master/slave parallel architecture for coordinating multiple units. In a parallel installation, all participating inverters must be the same model, and Deye specifies particular requirements regarding battery configuration and communication.

This scalability makes the SUN-100K-SG02HP3-EU-GM10 suitable as a building block for very high-power distributed energy-storage systems.

100% unbalanced output capability

Deye specifies 100% unbalanced output, providing additional flexibility in three-phase installations where the electrical demand is not distributed equally across all three phases.

The manual also contains an Asymmetric Phase Feeding function which can be used in applicable on-grid configurations to manage systems with uneven phase loading.

250 A continuous AC passthrough

The inverter supports up to 250 A continuous AC passthrough from the grid to the load, giving it substantial capacity when supplying connected loads while grid power is available.

Combined with the dedicated GRID, LOAD and GEN connections, this allows the inverter to form the central energy-management component of a sophisticated three-phase installation.
