Product Overview

The 30–500kW Microgrid Hybrid Inverter is designed for off-grid, weak-grid and hybrid microgrid applications requiring coordinated operation of solar PV, battery energy storage, diesel generators and AC loads.

Available in rated power levels from 30kW to 500kW, the MPS series combines power conversion, PV/MPPT integration, battery charging and discharging, grid/off-grid operation and generator coordination in one scalable platform.

The system supports multiple-machine parallel operation, 100% unbalanced loads, flexible PV configuration and diesel-generator load-rate control, making it particularly suitable for mines, islands, remote farms, villages and other locations where reliable power supply and fuel efficiency are important.

Model Range

AC On-Grid Specifications

AC Off-Grid Specifications

The MPS series can operate independently from the utility grid and establish a stable local AC microgrid.

This makes the inverter suitable for applications where the microgrid itself must maintain voltage and frequency without a stable utility grid.

PV Input

PV input can be configured according to project requirements and inverter capacity.

Flexible Solar Configuration

The modular MPPT design allows different PV capacities to be configured around the same base inverter power.

For example:

100kW MPS inverter

can be configured with approximately:

120kW / 180kW / 240kW PV input

depending on project requirements.

This is useful for remote microgrids where solar-array size may be designed according to local irradiation, daily energy demand and required generator operating hours.

Battery System

The wide battery voltage range allows the MPS series to work with different high-voltage battery energy-storage configurations.

Battery-system selection should be matched according to:

• Required backup time

• Daily energy consumption

• Peak load

• PV generation

• Diesel-generator capacity

• Battery charge/discharge rate

• Required autonomy

Diesel Generator Integration

One of the most important functions of the MPS series is diesel-generator coordination.

The controller can support DG load-rate control, helping the generator operate in a more efficient load range instead of frequently running at very low loads.

A typical configuration is:

Solar PV + Battery ESS + MPS Hybrid Inverter + Diesel Generator → Load

Typical Operating Logic

During strong solar production

Solar PV → Load
Excess Solar → Battery

When solar power decreases

Solar + Battery → Load

When battery SOC becomes low

Diesel Generator → Load + Battery Charging

When load demand increases sharply

Battery + Diesel Generator → Load

When renewable energy becomes sufficient again

Generator can be reduced or stopped according to the system control strategy.

Why Combine BESS with a Diesel Generator?

For remote and off-grid projects, running a diesel generator alone can result in:

• High fuel consumption

• Long generator operating hours

• Low-load operation

• Higher maintenance frequency

• Higher operating costs

Adding battery storage and solar PV allows the microgrid controller to coordinate different power sources.

The objective is not necessarily to eliminate the generator, but to use it only when it is needed and at a more efficient operating point.

This is particularly relevant to Linkworld Power because it connects your two major product lines:

Battery Energy Storage + Diesel Generator

into one complete hybrid power solution.

Integrated System Functions

The supplier describes the MPS system as integrating:

• PV / MPPT Module

• Transformer

• STS

• Maintenance Bypass

• Hybrid Power Conversion

• Battery Interface

• Generator Coordination

• Microgrid Control

This means the product is better positioned as a microgrid hybrid power platform rather than simply as an inverter.

Parallel & System Expansion

The series supports parallel connection of multiple machines, allowing larger microgrid systems to be built when required.

This provides flexibility for:

• Future load growth

• Larger battery capacity

• Larger PV installations

• Redundant system design

• Multi-unit microgrid projects

These interfaces allow the microgrid inverter to communicate with the battery BMS and external energy-management system.

Applications

Off-Grid Mining

Suitable for mining sites where utility power is unavailable or unreliable.

Solar and battery storage can reduce diesel-generator operating hours while maintaining stable power for mining loads.

Off-Grid Islands

Suitable for island microgrids traditionally dependent on diesel generation.

PV and battery storage can reduce fuel consumption and improve renewable-energy utilization.

Nomadic Farms & Remote Agriculture

Provides flexible power for farms, irrigation systems and remote agricultural facilities.

Villages Without Electricity

Can be used as the core power-conversion platform for rural electrification and independent community microgrids.

Additional Applications

These series can also be positioned for projects such as:

• Remote Industrial Facilities

• Telecom Sites

• Construction Camps

• Remote Resorts

• Oil & Gas Sites

• Rural Microgrids

• Emergency Power Systems

Project Configuration Example

For example, a remote mining site may require:

100kW Peak Load

150–200kWp Solar PV

300–500kWh Battery Storage

150kVA Diesel Generator

100kW MPS Microgrid Hybrid Inverter

The actual configuration should not be selected only according to peak load.

Before system sizing, we should collect:

• Peak load

• Average load

• 24-hour load profile

• Daily energy consumption

• Critical loads

• PV installation capacity

• Solar irradiation

• Required backup time

• Existing generator capacity

• Generator operating hours

• Fuel cost

• Ambient temperature

• Installation altitude

• Grid availability

Then determine:

PV Size + Battery kWh + PCS/Inverter kW + Generator kVA + Control Strategy
