Grid-Tied with Full Backup

Interconnected to the Grid – Full Backup

This system combines solar panels, high-capacity backup batteries, and connection to the utility grid (CFE). During the day, your system generates solar energy to power your home or business; when outages occur, the batteries automatically activate to keep the entire property running without interruptions.

Advantages

Continuous energy supply, even during outages.
Significant savings during daylight hours by using solar power.
Independence from grid failures.
Added property value by incorporating full energy backup.
Greater comfort and safety: lighting, refrigeration, and security operate without interruption.

Considerations

Higher upfront cost compared to partial backup: battery capacity must be sized to support all desired loads.
Requires adequate space for batteries and equipment.
Maintenance planning is essential to ensure the lifespan of batteries and inverter.

Main Components

Solar panels.
Inverter charger that switches seamlessly between solar, battery, and grid power.
Battery bank (ideally lithium) with adequate depth of discharge.
Controller: manages battery charging, protecting them and optimizing energy flow. There are all-in-one units that already have an inverter built in.
Real-time monitoring system (app/software) to track generation, consumption, and battery status.
Safety and protection devices (switches, surge protection, fuses, structural support).
