The SOONEST SF Series 1kW–10.2kW single-phase hybrid solar inverter integrates MPPT solar charging, battery management, utility input and pure sine wave output. It provides flexible energy management and reliable backup power for homes, offices, farms and off-grid solar systems.
The SOONEST SF Series 1kW–10.2kW Single-Phase Hybrid Solar Inverter combines solar energy conversion, battery charging, utility input and backup power management in one integrated unit.
Designed for homes, offices, farms, shops and remote properties, the inverter intelligently manages power from solar panels, batteries and the utility grid. It helps increase solar self-consumption, reduce dependence on grid electricity and maintain a stable power supply during outages.
With multiple output power options from 1kW to 10.2kW, the SF Series can support different system sizes, from essential household loads to larger residential and light commercial applications.
The SF Series is available in multiple output ratings from 1kW to 10.2kW.
Different models can be selected according to:
Exact available power ratings should be confirmed before ordering.
The inverter provides single-phase AC output for compatible residential and small commercial electrical systems.
Available output voltage and frequency options may include different regional standards. The required voltage and frequency must be confirmed before purchase.
The integrated MPPT solar charge controller continuously tracks the maximum available power from the photovoltaic array.
It automatically adjusts the operating point according to changes in sunlight and panel temperature, helping improve daily solar energy generation and charging efficiency.
The following specifications vary by model:
The inverter coordinates power from:
During daylight hours, solar energy can directly power the loads and charge the battery. When solar generation is insufficient, the inverter can use battery or utility power according to the selected operating priority.
Depending on the selected model, available operating modes may include:
These programmable modes allow the system to be configured according to local electricity tariffs, solar availability and backup requirements.
The inverter provides stable pure sine wave AC output suitable for compatible household and office equipment.
Typical loads may include:
The continuous load and starting power must remain within the specifications of the selected inverter.
Depending on the selected model, the SF Series may support compatible:
Battery voltage, charging current and charging parameters must match the inverter requirements.
Selected models may support communication with compatible lithium battery management systems through interfaces such as:
When communication is correctly configured, the inverter may monitor battery information including:
Battery communication protocols are not universal. Compatibility must be verified before ordering.
The integrated charger can use available solar energy to charge the connected battery.
On supported models, utility electricity can also charge the battery when solar generation is insufficient or scheduled grid charging is enabled.
The charging voltage and maximum charging current must be configured according to the selected battery.
When connected to a compatible battery system, the inverter can provide electricity to designated loads during a utility-grid outage.
Actual backup time depends on:
Essential equipment should be connected through a properly designed backup circuit.
The front display provides access to system operating information and programmable settings.
Depending on the selected model, users may be able to view:
Selected SF Series models may support optional remote monitoring through:
Monitoring accessories and available functions vary by model.
Available software and hardware protection functions may include:
Exact protection functions should be confirmed from the selected model’s technical datasheet.
The compact enclosure is suitable for wall-mounted installation in homes, utility rooms, offices and other protected environments.
Adequate clearance and ventilation should be maintained around the inverter to support heat dissipation and reliable operation.
The SOONEST SF Series hybrid inverter is suitable for:
During the daytime, solar panels generate DC electricity.
The inverter converts solar energy into AC electricity for connected loads. When solar generation exceeds current consumption, excess energy can be used to charge the battery.
When solar production decreases, stored battery energy can support the connected loads. If both solar and battery power are insufficient, utility electricity can provide additional power when available.
During a grid outage, the inverter can continue supplying designated backup loads when sufficient battery energy is available.
