Built to Resist. Engineered to Survive.

Built with 100% solid-state battery cells that resist fire, overcharge, and extreme pressure - without breaking a sweat. But safety doesn’t stop there.

The SurgeGuard™ Defense System(SDS) is a next-gen active protection mechanism. When the BMS detects temperatures exceeding 392°F (200°C), SDS instantly deploys inert gas to isolate air and stop ignition at its source within a second.

Frequently Asked Questions (FAQ)

Have a Question? We’ve Got the Answer!

How does POWISER ULTRA ensure electrical safety and minimize fire risks?

POWISER ULTRA uses solid-state battery technology, which is inherently more stable than traditional liquid batteries due to its non-flammable electrolyte. Even in extreme conditions, if a thermal event occurs, ULTRA’s AI-powered monitoring system detects temperature spikes within 0.8 seconds and activates the SurgeGuard™ Defense System (SDS). This releases inert gas to smother flames by cutting off oxygen, ensuring rapid fire suppression.

Why choose solid-state batteries over conventional lithium-ion/LiFePO4?

Solid-state batteries offer: - Enhanced Safety: No flammable liquid electrolytes, reducing fire risks. - Extreme Environment Adaptability: Operates reliably in -40°C to 40°C (unlike liquid batteries, which degrade in extreme cold/heat). - Longer Lifespan: Higher cycle stability with minimal capacity loss over time.

What does 10 kWh mean?

The 10 kWh capacity ensures sustained power for hours, even at peak loads. You can power:
- Household: Powers essentials for 8–15 hours (e.g., fridge + lights + router).
  - RV Road Trip: Runs a mini-fridge, LED lights, and a CPAP machine for ~24 hours.
  - Garage/Workshop: Supports power tools (e.g., 1kW saw) for 10 hours or a 500W fridge for 20 hours.

Absolutely! 12kW output means ULTRA can simultaneously support: Central AC (3.5kW) + Refrigerator (1kW) + Microwave (1.2kW) + **LED Lights (0.2kW) with room to spare.

The 10 kWh capacity ensures sustained power for hours, even at peak loads. You can power:
- Household: Powers essentials for 8–15 hours (e.g., fridge + lights + router).
  - RV Road Trip: Runs a mini-fridge, LED lights, and a CPAP machine for ~24 hours.
  - Garage/Workshop: Supports power tools (e.g., 1kW saw) for 10 hours or a 500W fridge for 20 hours.

How do I charge ULTRA with solar panels?

ULTRA supports dual solar input modes:
 1. High-Voltage (150V–500V): Connect to rooftop solar arrays via a professional grid-tied inverter or directly to the HV SOLAR input port.
2. Low-Voltage (12V–150V): Use portable/balcony solar panels plugged into the LV input.

*Pro Tip: For off-grid setups, pair with a microinverter for optimal efficiency.

What’s the advantage of 120V/240V split-phase output?

Split-phase power lets ULTRA:
  - Run 240V heavy-duty appliances (e.g., water pumps, electric stoves).
  - Balance loads efficiently across 120V circuits (standard U.S. outlets).
  - Eliminate the need for external transformers, simplifying integration with home/RV systems.

How long does ULTRA take to charge from 0% to 100%?

With 12kW AC input: ~1 hour. Solar charging depends on panel wattage (e.g., 2+ hours with 6 kW solar array).
