How to keep my home powered during outages?

SolaX solar battery systems with built-in EPS (Emergency Power Supply) functionality automatically supply power to essential loads during grid failures. The system features UPS-level switching time of under 10 milliseconds, ensuring devices like refrigerators, lights, routers, and medical equipment continue running without reboot or delay.

How to maximize solar self-consumption?

SolaX EPS-enabled systems allow homeowners to store excess solar energy and use it during blackouts or peak-rate hours. This approach reduces reliance on the grid and utility companies while ensuring better utilization of your stored solar energy.

How quickly does an integrated backup power system activate during a grid outage?

High-performance emergency power systems offer UPS-level switching times of under 10 milliseconds. This means the transition from grid power to battery backup is virtually instant and seamless, ensuring that sensitive devices such as refrigerators, routers, and medical equipment continue to operate without rebooting or experiencing delays.

Can a battery backup system help reduce my monthly electricity bills?

Yes. In addition to providing power during blackouts, these systems allow homeowners to store excess solar energy and discharge it during expensive peak-rate hours. By better utilizing stored renewable energy and reducing reliance on utility power when rates are highest, users can achieve significant long-term cost savings.

What are the primary advantages of a battery-based backup system compared to a traditional diesel generator?

Battery-based systems provide a fully automatic and silent power solution with zero emissions, whereas diesel generators are often noisy, require manual starting, and can take over 15 seconds to activate. Furthermore, battery systems integrate seamlessly with solar arrays to provide true energy autonomy, making them a more sustainable and resilient alternative for modern homes.

Emergency Power Supply: Ensure 24/7 Power with SolaX Solar Battery Systems

In a world where power outages are increasingly frequent due to extreme weather, aging infrastructure, and rising energy costs, energy resilience has become a top priority for homeowners. SolaX Power, a global leader in smart energy solutions, offers UPS-level Emergency Power Supply (EPS) functionality built into its solar battery systems—ensuring uninterrupted power during grid failures.

What is EPS in SolaX Solar Battery Systems?

EPS (Emergency Power Supply) in SolaX systems is an integrated backup power feature that ensures critical appliances remain powered during grid outages. When combined with a SolaX hybrid inverter and solar battery, EPS automatically supplies power to selected essential loads through a dedicated EPS output.

What sets SolaX apart is its UPS-level switching time of under 10 milliseconds—According to the ITI (CBEMA) Curve, the global industry standard for power quality, most modern Information Technology Equipment (ITE) can only withstand a complete power interruption for a maximum of 20 milliseconds before experiencing a system reboot or data corruption, which means that the transition from grid power to battery backup is instant and seamless. Devices like refrigerators, lights, routers, and medical equipment continue running without reboot or delay.

Benefits of SolaX EPS for Residential Backup Power

Uninterrupted Power (UPS-Level Performance)

SolaX EPS guarantees a sub-10ms switchover time, preventing power loss to sensitive electronics. This makes it ideal for homes relying on continuous connectivity and safety.

True Energy Independence

EPS allows homeowners to store excess solar energy and use it during blackouts or peak-rate hours, reducing reliance on the grid and utility companies.

Cost Savings

The EIA reported that residential electricity prices increased by over 6% in August 2025, raising concerns among developers, analysts, and policymakers as costs rise. EPS-enabled systems allow better utilization of your stored solar energy, especially during expensive peak hours or outages, reducing reliance on utility power. Over time, this contributes to significant energy cost savings.
