FSolar Atlantic F12 12kVA 48V Hybrid Solar Inverter

The FSolar Atlantic F12 is a high-performance 12kVA hybrid solar inverter engineered for large residential installations, commercial power systems, backup applications, and off-grid solar energy solutions.

Designed for a 48V battery system, the Atlantic F12 intelligently manages power from solar panels, batteries, utility electricity, and compatible generators. It provides stable pure sine wave output for appliances, office equipment, pumps, motors, lighting, electronics, and other compatible electrical loads.

With a rated output capacity of 12kVA and a powerful 24kVA surge capacity, the inverter can support demanding loads and equipment with high starting-power requirements.

Dual MPPT Solar Charging

The FSolar Atlantic F12 is equipped with dual MPPT solar trackers, allowing two separate solar arrays or panel orientations to be connected and managed efficiently.

The inverter supports up to 15kW of total PV input power when both MPPT inputs are used. A single MPPT supports up to 9kW, while the dual-input configuration supports 27A + 27A of PV input current.

Solar Input Specifications

• Solar charger type: Dual MPPT
• Single MPPT capacity: 27A / up to 9kW

• MPPT operating voltage range: 60V–450V DC
• Maximum PV open-circuit voltage: 500V DC
• Maximum PV charging current: 160A

Solar panel strings must be designed so that the total open-circuit voltage remains safely below the inverter’s maximum PV voltage under all expected weather conditions.

160A High-Capacity Battery Charging

The Atlantic F12 provides powerful battery charging from solar panels, utility power, or a compatible generator.

Charging Performance

• Maximum PV charging current: 160A
• Maximum AC charging current: 160A
• Maximum combined charging current: 160A
• Maximum battery discharge current: 220A

The charge and discharge settings must always be configured according to the connected battery manufacturer’s permitted limits.

Lithium and Lead-Acid Battery Compatibility

The inverter supports both lithium and lead-acid battery systems, providing flexibility for different energy-storage applications.

It includes RS232, RS485, and CAN communication interfaces, enabling communication with compatible lithium battery management systems.

Battery and Communication Features

• LCD display
• Built-in system monitoring

Battery communication compatibility and protocol settings must be confirmed before installation.

Flexible Grid and Generator Operation

The FSolar Atlantic F12 can operate with utility electricity and compatible generators, making it suitable for locations with unstable grid supply or installations that require an additional backup energy source.

Its wide AC input voltage range allows the inverter to adapt to different operating conditions:

• Normal mode input range: 90V–280V AC
• UPS mode input range: 170V–264V AC
• Input frequency: 50Hz / 60Hz, automatically adaptive

LCD Display and System Communication

The integrated LCD display provides access to important operating information, including solar production, battery status, AC input, output power, load condition, charging status, and system warnings.

Multiple communication interfaces make the inverter suitable for integration with compatible batteries and energy-management systems.
