The Firman 11kW Hybrid On-Off Inverter (FH11K0110) is a high-precision power management system designed for heavy-duty residential and commercial use. It functions as a "hybrid" unit, meaning it intelligently switches between solar, battery, and grid power to ensure 24/7 electricity.
Core Functionality & Design
Dual Architecture: Available in two main versions to suit different needs:
Transformer-Based (Low Frequency): Uses a heavy iron-core transformer, providing galvanic isolation for superior safety and the ability to handle high "surge" currents from inductive loads like pumping machines and large ACs.
Transformerless (High Frequency): Uses advanced electronics to be more energy-efficient (up to 99%) and significantly lighter (~19.3kg), making it ideal for modern homes with lithium setups.
Smart Energy Management: Features a configurable priority system (via touch screen) that lets you decide whether to use solar, battery, or the grid first.
Parallel Capability: The system can be expanded by connecting up to 6 units in parallel for massive power requirements.
Technical Specifications
Power Capacity: 11,000 Watts rated output with a 1.0 Power Factor, meaning it delivers its full stated wattage.
Solar Input: Equipped with dual MPPT controllers supporting a maximum PV array of 11,000W (2 x 5,500W) and a high input voltage range of 120V to 500V.
Battery System: Operates on a 48V DC nominal voltage; compatible with both Lead-Acid and Lithium-ion (LiFePO4) batteries with a dedicated BMS communication port (RS485/CAN).
Operating Noise: Extremely quiet operation at less than 45dB, making it suitable for indoor installation.
Operational Features
Monitoring: Built-in Wi-Fi data logger (optional) and an intuitive LCD/LED display for real-time tracking of battery status, load levels, and fault records.
Protection: Includes an IP20-rated enclosure and comprehensive safeguards against over-voltage, short circuits, and over-temperature.
WiFi Control: Features integrated WiFi functionality for remote monitoring via smartphone apps.
Do you need help calculating how many 550W solar panels are required to reach the maximum 11kW charging capacity for this unit?
