As one of the leading off grid inverter manufacturers, FRECON offers a compact, intelligent solution tailored for solar energy systems in remote or grid-unstable regions.
1. Pure Sine Wave Output
The FRECON SP520 is a pure sine wave off grid inverter, delivering utility-grade AC power that protects sensitive equipment from damage, overheating, noise, or device failure.
2. Configurable output source priority
Our grid off inverter can automatically switch between solar power, battery, grid electricity, or a generator, which means it always selects the best energy source available, preventing outages caused by low sunlight or unstable grid supply.
3. Configurable AC/Solar charger priority
Our inverters for off grid enable you to decide whether the charging sources are first from solar energy or from the AC grid, helping users reduce electricity bills by maximizing solar energy utilization.
4. Built-in 120-450V MPPT solar charger controller
Our SP520 grid off inverter boasts a Built-in MPPT controller, which can solve low power generation issues caused by cloudy weather, unstable sunlight angles, and voltage fluctuations, significantly improving the overall energy harvest.
5. Support no battery operation function
SP520 off grid inverter can operate directly from solar input without requiring batteries, reducing battery-related costs, maintenance, and safety concerns.
6. Compatible to grid power or generator power
This FRECON SP520 is the best inverter for off grid solar system, as it can seamlessly work with grid power or diesel generators as backup, ensuring uninterrupted supply when solar input is low.
7. Built-in Wi-Fi & App Monitoring
The SP520 series grid off inverter is equipped with a built-in Wi‑Fi module, which allows you to monitor the status and performance data of the equipment via a mobile app in real time, helping to reduce on-site maintenance time and operational costs.
8. Comprehensive System Protection
Our SP520 grid off inverter is equipped with complete short-circuit, over-voltage, under-voltage and overload protection, etc., improving overall system reliability and prolonging the lifespan of the inverter.
