FRECON provides specialized architectures depending on whether you are powering a standard home or industrial equipment. Note that FRECON SP series inverters are primarily single-phase units on the AC side.
For Home & Small Office (Single-Phase):
The SP500 Series is our flagship off-grid inverter.
· Pure Sine Wave: Provides clean 230V output for standard household and office loads.
· High-Voltage MPPT: Optimizes solar harvest for residential backup systems.
For Professional & Specialized Applications
While both the SP520 Plus and SP600 are pure-sine, MPPT-based off-grid inverters, they are engineered to support distinct professional scenarios.
SP520 Plus: Flexible Hybrid Power Core
The SP520 Plus is optimized as a flexible hub for buildings and critical loads that require precise energy management.
· Complex String Management: A wide 120–500 VDC PV window and 100 A MPPT allow it to handle complex arrays with simpler wiring.
· System Integration: Includes a dry-contact output for clean interfacing with BMS, generators, or external alarms.
· Intensive Cycle Reliability: Features smart battery management and automatic equalization to extend battery life in demanding daily-use environments.
SP600: High-Demand Off-Grid Backbone
The SP600 is designed as a robust backbone for higher-power, more demanding installations such as workshops or agricultural processing centers.
· Higher Power Class: Rated around 5.5 kW, it is built to handle the larger aggregated loads of small factories and mixed building complexes.
· Inductive Load Protection: Specifically designed with full electronic protections (over-voltage, overload, and short-circuit) to safely run heavier machinery without damaging sensitive components.
· Industrial Coordination: Its design emphasizes reliability for sites where inverter trips would halt production or critical services.
