The Firman 6kW (6kVA) Smart Hybrid Inverter is an advanced, transformerless power solution designed for high-efficiency energy management in residential and commercial settings. It is engineered to seamlessly integrate solar energy, battery storage, and public grid/generator inputs to provide reliable, uninterruptible power.
Core Functionality & Design
Transformerless Technology: This design makes the unit significantly lighter (approx. 13kg) and more compact than traditional transformer-based inverters. It achieves higher conversion efficiency (95%+) but is more sensitive to high-surge startup loads like industrial pumps.
Hybrid Management: The inverter intelligently prioritizes power sources based on user settings:
Solar Priority: Uses solar first, switching to batteries or the grid only when solar is insufficient.
Grid Priority: Relies on the grid primarily, using solar and batteries as backup.
Battery Priority: Uses battery power until low, then switches to solar or grid to recharge.
Smart Monitoring: Features a built-in WiFi module that allows users to track real-time energy production and battery status via smartphone apps or web platforms.
Detailed Specifications
Power Capacity: 6kW (6000W) continuous output.
Input Range: Wide PV input voltage range from 120V to 500V DC, allowing for flexible solar panel configurations.
Battery System: Operates on a 48V DC nominal battery bank and is compatible with both Lithium-ion (Li-ion) and Lead-Acid batteries.
Quiet Operation: Maintains noise levels below 45dB, making it suitable for indoor residential use without disturbance.
Expansion: Supports parallel connection, allowing multiple units to be linked to increase total system capacity as power needs grow.
Typical Load Capability
A 6kVA setup is robust enough to power a typical three-bedroom flat. It can handle:
Heavy Appliances: 1 to 2 inverter air conditioners, a pumping machine (daytime use recommended), and a refrigerator or freezer.
Essentials: Multiple fans, LED lighting, TVs, sound systems, and laptops.
Kitchen/Laundry: Microwave, blender, and washing machine (note: heavy loads should not all run simultaneously).
Safety & Warranty
The unit is housed in an IP20-rated enclosure for protection against dust and includes comprehensive safety features such as overload and short-circuit protection. It typically comes with a 2 to 5-year warranty.
