Product Details

Scalable Hybrid Solar Power for Residential and Commercial Systems

The SOONEST MC Series Hybrid Solar Inverter is available in 6.2kW and 11kW models for residential, off-grid and light commercial solar energy systems.

It integrates solar charging, battery management, utility input and AC power output into one compact unit. The inverter can intelligently coordinate energy from solar panels, batteries and the utility grid to increase solar self-consumption and provide reliable backup power.

Selected MC Series models support parallel operation, allowing multiple compatible inverters to work together when higher output power or greater system capacity is required.

Key Features

6.2kW and 11kW Power Options

The MC Series is available in two output power ratings:

  • 6.2kW
  • 11kW

The 6.2kW model is suitable for common household loads and small off-grid systems, while the 11kW model can support larger homes, farms, offices and light commercial applications.

The correct model should be selected according to the total continuous load and the starting power of connected equipment.

Single-Phase AC Output

The inverter provides single-phase AC output for compatible residential and commercial electrical systems.

Available output voltage and frequency options may vary by model and destination market. Confirm the required electrical standard before ordering.

Parallel Operation

Selected MC Series models support parallel connection, allowing multiple compatible units to operate as one larger power system.

Parallel operation can provide:

  • Higher total output power
  • Greater system flexibility
  • Easier future expansion
  • Improved load distribution
  • Support for larger backup systems

The maximum number of parallel units, required communication cables and supported configurations must be confirmed according to the selected model.

Intelligent MPPT Solar Charging

The integrated MPPT solar charge controller continuously tracks the maximum available power from the PV array.

It automatically adjusts the operating point according to sunlight and panel temperature, helping improve daily solar energy harvesting.

The following specifications vary by model:

  • MPPT voltage range
  • Maximum PV input voltage
  • Maximum PV input current
  • Maximum solar-array power
  • Number of MPPT channels

Hybrid Energy Management

The inverter manages electricity from:

  • Solar panels
  • Battery storage
  • Utility grid
  • Connected loads

During the daytime, solar energy can power the loads and charge the battery. When solar generation is insufficient, the system can use battery or utility power according to the selected operating priority.

Multiple Operating Modes

Available operating modes may include:

  • Solar priority
  • Battery priority
  • Utility priority
  • Self-consumption mode
  • Backup power mode
  • Off-grid operation
  • Scheduled utility charging
  • Time-of-use charging and discharging

Available modes and programmable settings may vary between the 6.2kW and 11kW models.

Pure Sine Wave Output

The MC Series provides stable pure sine wave AC output for compatible household and commercial electrical equipment.

Typical loads may include:

  • Lighting
  • Refrigerators and freezers
  • Televisions
  • Computers
  • Fans
  • Communication equipment
  • Security systems
  • Water pumps
  • Office equipment
  • Compatible air-conditioning units
  • Other household appliances

The total load and surge demand must remain within the selected inverter’s rated limits.

Flexible Battery Compatibility

Depending on the selected model, the inverter may support compatible:

  • LiFePO4 batteries
  • Lithium-ion batteries
  • AGM batteries
  • GEL batteries
  • Flooded lead-acid batteries

Battery voltage, charging current and communication compatibility must be confirmed before system installation.

Lithium Battery BMS Communication

Selected models may communicate with compatible lithium battery management systems through interfaces such as:

  • CAN
  • RS485
  • RS232

When properly configured, the inverter may receive battery information including:

  • State of charge
  • Battery voltage
  • Charging current
  • Discharging current
  • Battery temperature
  • Warning status
  • Fault information

Battery communication protocols are not universal. Compatibility with the selected battery brand must be verified before ordering.

Solar and Utility Battery Charging

The integrated charging system can manage battery charging from solar energy and, on supported configurations, utility electricity.

Charging priorities and current limits may be adjusted according to the battery type, available solar generation and backup requirements.

Correct charging parameters must be used to protect the battery and maintain dependable operation.

Reliable Backup Power

When connected to a compatible battery system, the inverter can supply designated loads during a utility-grid outage.

Backup duration depends on:

  • Battery capacity
  • Battery state of charge
  • Connected load
  • Inverter efficiency
  • Available solar generation
  • System operating settings

A dedicated backup-load circuit should be designed by a qualified technician.

User-Friendly Display

The front display provides access to operating data and system settings.

Depending on the model, users may be able to monitor:

  • Solar input power
  • PV voltage and current
  • Battery voltage
  • Battery state of charge
  • Charging and discharging status
  • Utility input
  • AC output
  • Load percentage
  • Operating mode
  • Warning and fault codes

Optional Remote Monitoring

Selected models may support optional remote monitoring through compatible accessories.

Available options may include:

  • Wi-Fi monitoring
  • Mobile application
  • Online monitoring platform
  • USB communication
  • RS485 communication
  • Remote fault checking

Monitoring functions and accessories should be confirmed for the selected model.

Typical Applications

The SOONEST MC Series hybrid inverter is suitable for:

  • Residential solar energy systems
  • Home battery storage
  • Whole-home backup power
  • Villas and large houses
  • Farms and rural properties
  • Small offices
  • Retail stores
  • Workshops
  • Restaurants and cafés
  • Cabins and remote buildings
  • Areas with unstable grid electricity
  • Off-grid solar systems
  • Solar self-consumption projects
  • Expandable parallel inverter systems
  • Light commercial backup power

How the System Works

During daylight hours, solar panels generate DC electricity.

The inverter converts solar energy into usable AC electricity for connected loads. Excess solar power can be used to charge the battery.

When solar generation falls below the load demand, the battery can discharge to support connected equipment. If solar and battery energy are insufficient, utility electricity can supply the remaining power when grid input is available.

During a grid outage, the inverter can continue powering designated backup loads if sufficient battery energy is available.

In a parallel system, multiple compatible inverters communicate and share the connected load according to the approved system design.
