The SOONEST SF Series 1kW–10.2kW single-phase hybrid solar inverter supports compatible 24V or 48V battery systems. Featuring intelligent MPPT charging, pure sine wave output, flexible energy management and backup power capability, it is suitable for homes, offices, farms and small commercial solar systems.
The SOONEST SF Series Hybrid Solar Inverter is designed for residential, office, retail, agricultural and small commercial solar energy systems.
Available in 4.2kW, 6.2kW, 8.2kW and 10.2kW power options, the SF Series intelligently manages energy from solar panels, battery storage, utility power and connected loads.
It can help increase solar self-consumption, reduce dependence on the utility grid and provide backup power when used with a compatible battery system.
The SF Series is available in several output power ratings:
This wide power range allows users to select a suitable inverter according to their household loads, solar panel capacity and backup power requirements.
Different SF Series models are available for compatible 24V or 48V battery systems.
Depending on the selected model, the inverter may support:
Battery voltage, charging current and communication compatibility must be confirmed before ordering.
The integrated MPPT solar charge controller continuously tracks the maximum available power from the solar panels.
It automatically adjusts the PV operating point according to sunlight and panel temperature, helping improve solar energy utilization throughout the day.
The PV input voltage, maximum input current and number of MPPT channels vary by model.
The inverter intelligently manages energy from:
Solar energy can be used directly to power connected equipment and charge the battery. When solar energy is insufficient, the system can use battery or utility power according to the selected operating mode.
Depending on the selected model, available operating modes may include:
These flexible operating modes allow the system to be configured for different electricity tariffs, backup requirements and solar energy strategies.
The inverter provides stable pure sine wave AC output for compatible household and light commercial equipment.
It is suitable for powering electrical loads such as:
When connected to a compatible battery system, the SF Series can provide backup power during utility outages.
The available backup time depends on:
Essential loads should be connected through a properly designed backup circuit.
The built-in charging system automatically manages battery charging and discharging according to solar generation, battery status and load demand.
Selected models may support lithium battery BMS communication for monitoring information such as:
BMS communication protocols must be confirmed according to the selected battery brand and inverter model.
The front display provides convenient access to important system information.
Users can view data such as:
The control panel also allows users to configure basic system parameters.
Selected models may support optional remote monitoring through:
Monitoring accessories and communication functions may vary by model.
The SF Series includes multiple software and hardware protection functions for safe and reliable operation.
Available protection functions may include:
Protection functions vary according to the selected model.
The SF Series hybrid inverter is suitable for:
During the daytime, solar panels generate electricity to power connected loads.
When solar generation is higher than current load demand, excess energy can be used to charge the battery. When solar production decreases, the battery can discharge to support connected equipment.
If solar and battery energy are insufficient, utility power can supply the remaining electricity according to the selected operating mode.
During a grid outage, the inverter can continue supplying designated loads when a compatible battery system is connected and sufficient stored energy is available.
