The most frequent cause of system failure is the inductive load. Motors found in pumps, compressors, and power tools require an "Inrush Current". A massive energy spike to start spinning that can be 3 to 5 times their running wattage.
If you connect a 1000W well pump to a standard 2000W inverter, it will likely trip because the pump demands a split-second surge of up to 4000W to start. Industrial inverters use heavy-duty toroidal transformers and high-capacity IGBTs to deliver this momentary magnetic field instantly.
Choosing the Right FRECON Series
FRECON provides distinct series engineered for specific professional environments. It is critical to select the correct line for your application.
SP Series: Off-Grid & Hybrid Solar Inverters
The SP Series (e.g., SP500, SP600) is designed to supply household or office AC loads from solar and batteries.
Target Loads: General AC equipment like lights, computers, and appliances.
2x Surge Capacity: A 2000W unit is typically rated to handle peaks of 4000W for motor startup.
Integrated Management: Features built-in MPPT solar charge controllers and configurable priority settings.
PV Series: Dedicated Solar Pumping Inverters
The PV Series (e.g., PV150, PV500) is engineered strictly for driving AC water pumps directly from PV panels.
Pump Optimization: Includes advanced MPPT control and dry-run protection specifically for agricultural or industrial irrigation.
Application Note: These units are specialized industrial tools and are not intended for household or office use. They should not be grouped with SP Series units for general AC power needs.
Conclusion
When selecting an inverter for professional use, always look beyond the "2000W" label. If your application involves any type of motor or pump, prioritize an industrial-grade unit like the FRECON SP Series that provides the necessary "headroom" for startup spikes.
