SOLAX X3-EPS Box
Product details
Solax EPS BOX Emergency Power Box (X1/X3)
The Solax EPS BOX is a key accessory for Solax G4 hybrid inverters (X1 and X3) that enables the Emergency Power Supply (EPS) function. It allows the photovoltaic system to automatically switch to backup power in the event of a grid outage, ensuring uninterrupted energy supply for the entire home. Integrated dual contactors simplify installation and enhance the safety of the whole system.
Key features of the Solax EPS BOX:
- Automatic emergency power: The box provides intelligent, near-instant switching (switching time 0.5 s) between grid power and emergency mode, ensuring uninterrupted operation of essential household devices.
- Simplified installation and increased safety: Integrating two contactors into a single enclosure significantly simplifies the wiring of the backup power system and improves operational safety.
- Support for single-phase and three-phase installations: Two dedicated versions are available: the X1 EPS BOX for single-phase systems and the X3 EPS BOX for three-phase systems, providing an ideal fit for any Solax G4 hybrid inverter.
- Whole-home backup power: The device is designed to manage backup circuits, enabling power to the entire home or selected critical loads during a grid failure.
- High resistance to external conditions: The IP65-rated enclosure ensures dust-tight protection and protection against water jets, allowing safe installation in various locations.
Who is it a good choice for?
This is an essential component for any owner of a Solax X1-Hybrid G4 or X3-Hybrid G4 inverter who wants to make the most of their system and protect their home from power interruptions. The EPS BOX is an ideal solution for those who value energy independence and comfort. With it, a public grid outage becomes practically unnoticeable, and household members can enjoy continuous access to the energy stored in batteries.
