Model Range

Technical Specifications

PV Input

The system supports flexible PV array design and high-power PV modules, making it suitable for modern commercial solar projects.

Battery Input

Maximum Charge / Discharge Power

The two independent battery ports provide additional flexibility for battery configuration and future capacity expansion.

AC Grid Output

Rated Output Current

Grid AC Input

The inverter supports bidirectional grid interaction, allowing the system to charge the battery from the grid when required and discharge energy according to the configured energy-management strategy.

The AC passthrough capability is suitable for systems requiring both grid supply and backup-load operation.

Diesel Generator Input

One of the main advantages of this series is its integrated diesel generator interface.

The inverter can coordinate:

Diesel Generator + Battery + Solar PV + Grid

Generator input can be used for:

• Backup power

• Battery charging

• Hybrid off-grid operation

• Weak-grid support

• Remote sites

• Peak load support

The system supports generator input over a relatively wide operating range, helping reduce unnecessary generator oversizing.

For your Linkworld Power positioning, this is one of the features I would emphasize most.

Backup / Off-Grid Output

The inverter provides backup power for critical loads when grid power is unavailable.

Key Backup Features

• Fast transfer <10ms

• Rated backup power up to 50kW

• Up to 160% rated power for 2 seconds

• Three-phase output

• Intelligent critical-load prioritization

• Battery reserve management

• On-grid and off-grid operation

This makes the series suitable for facilities where uninterrupted power supply is important.

Efficiency

Hybrid Power Integration

A typical system can combine:

Solar PV

Provides renewable power to local loads and charges the battery.

Battery Energy Storage

Stores surplus energy and provides backup or peak-shaving power.

Grid

Provides supplemental power or receives excess energy according to system configuration.

Diesel Generator

Provides backup generation and can support battery charging when required.

Hybrid Inverter

Coordinates energy conversion and distribution between all energy sources.

A typical configuration is:

Solar PV → Hybrid Inverter ← Battery ESS

Grid ↔ Hybrid Inverter → Loads

Diesel Generator → Hybrid Inverter → Loads / Battery

This architecture is particularly suitable for Solar + BESS + Generator + Grid hybrid projects.

Smart Energy Management

The inverter supports intelligent system control for applications such as:

• Solar self-consumption

• Peak shaving

• Battery reserve management

• Time-of-use energy management

• Critical load prioritization

• Generator-assisted charging

• Backup power

• Microgrid operation

Remote monitoring and energy-management functions can also be supported through the manufacturer's monitoring platform.

Parallel System Expansion

Multiple units can be connected in parallel for larger projects.

The series supports system expansion up to approximately:

500kW

For larger parallel systems, additional system switching/control equipment may be required according to the project configuration.

This means you can use the same inverter family for projects ranging from smaller C&I installations to larger commercial energy-storage systems.

Protection Functions

The inverter includes multiple protection functions, including:

• Anti-Islanding Protection

• Output Over-Current Protection

• Short-Circuit Protection

• DC Reverse Polarity Protection

• Integrated DC Switch

• Surge Protection

• Battery Protection

• Grid Monitoring

• Optional AFCI Protection
