Key Product Features

6kW Single-Phase Output

The inverter provides a 6,000W rated AC output, making it suitable for a wide range of residential and small commercial applications.

It can supply essential and high-demand household loads while providing battery and solar integration for improved energy independence.

Off-Grid Hybrid Operation

Designed primarily for off-grid and backup applications, the inverter can intelligently manage power from multiple sources, including:

• Solar PV
• Battery storage
• Utility/grid input
• Diesel generators

This enables the system to automatically utilise available energy sources according to the configured operating strategy.

High Solar PV Input Capacity

The SUN-6K-OG01LP1-EU-AM2 supports up to 12,000W of maximum PV input power, providing substantial solar-generation capacity relative to its 6kW AC output.

This allows additional PV capacity to be installed to improve solar production, particularly during periods of lower solar irradiation.

The inverter features two MPPTs, providing flexible solar-panel configuration and improved energy harvesting from PV arrays with different orientations or operating conditions.

40–60V Battery System

The inverter supports both:

• Lithium batteries
• Lead-acid batteries

with a battery voltage range of 40–60V.

For compatible lithium battery systems, the inverter uses a self-adaptive BMS charging strategy, helping coordinate battery charging according to battery-management-system requirements.

135A Maximum Battery Current

With a maximum 135A charging/discharging current, the inverter can support high-power battery charging and discharge.

This allows surplus solar energy to be stored efficiently during periods of generation and made available to loads when solar production is insufficient.

AC Coupling

The inverter supports AC coupling, allowing it to be integrated with suitable existing solar installations.

This makes it useful for customers looking to upgrade an existing PV system by adding battery storage and backup functionality without necessarily replacing the entire solar installation.

Up to 16 Inverters in Parallel

Up to 16 units can operate in parallel, allowing system capacity to be expanded as energy requirements increase.

Parallel operation provides flexibility for larger residential, commercial, and off-grid projects requiring more power or increased system redundancy.

Multiple Batteries in Parallel

The system supports the use of multiple batteries in parallel, allowing installers to scale the available energy-storage capacity according to the application’s requirements.

This makes it possible to design systems with increased backup runtime and greater energy-storage capacity.

Diesel Generator Compatibility

The SUN-6K-OG01LP1-EU-AM2 supports integration with diesel generators, providing an additional energy source for off-grid and backup applications.

A generator can provide power when solar generation is insufficient and battery energy is depleted or when additional power is required.

High Peak Off-Grid Power

The inverter can deliver up to 2× its rated power for 10 seconds in off-grid operation.

This high peak-power capability helps accommodate loads with significant startup or surge requirements, such as certain pumps, motors, compressors, and other equipment.

Intelligent Touchscreen Display

The inverter features a colour LCD touch display, providing an intuitive interface for configuration, system status, and real-time monitoring.

The display allows users and installers to conveniently view operating information and configure supported inverter functions.

Communication and Monitoring

The SUN-6K-OG01LP1-EU-AM2 provides multiple communication options for monitoring, battery communication, and system integration.

Available interfaces include:

• Wi-Fi
• RS485
• CAN

These communication interfaces allow the inverter to communicate with compatible battery-management systems and monitoring platforms.

High Efficiency

The inverter is designed for efficient conversion of solar and battery energy.

Efficiency Specifications

• Maximum efficiency: 97.6%

Surge Protection

The inverter incorporates:

• Type II surge protection on the DC side
• Type II surge protection on the AC side

These protection measures help protect the inverter and connected equipment against electrical surges.

IP65-Rated Enclosure

The inverter features an IP65 protection rating, providing a high level of protection against dust and water ingress when correctly installed.

This makes it suitable for both indoor and outdoor applications, subject to the manufacturer’s installation requirements.

Wide Operating Temperature Range

The inverter is designed to operate across a wide temperature range of:

-40°C to +60°C

Performance derating applies above 45°C.

This wide operating range makes the inverter suitable for demanding environmental conditions.

Intelligent Cooling

The SUN-6K-OG01LP1-EU-AM2 uses intelligent air cooling to help regulate internal operating temperatures.

Its cooling system is designed to maintain reliable performance while keeping operating noise below 46dB.

Suitable Applications

The Deye 6kW hybrid inverter is suitable for a variety of applications, including:

Residential Solar Systems

Ideal for homes requiring solar generation, battery storage, and backup power.

Off-Grid Homes
