Power-Plant-in-a-Box™

Power-Plant-in-a-Box™ is a fully integrated system that provides continuous renewable electricity on-site. At its heart is HyWatts’ Energy Conversion System, that transforms excess solar power into hydrogen and reconverts it to electricity on demand—ensuring reliable energy even when the sun isn’t shining. No reliance on local grid infrastructure is necessary, making it perfect for partially grid-connected or fully off-grid scenarios.

Solar Panels

Generating green electric power
HyWatts’ Energy Conversion System

Converting the excess electricity to hydrogen and then back to electricity, on demand.
Energy Management System

Responsible for managing the overall system operation
Power Distribution System

Responsible for conditioning and distributing electric power between different subsystems and to the user.

During times of high generation and low demand, the HyWatts system directs excess electricity into hydrogen production, which is accumulated physically in vessels for later use. When renewable generation dips or demand spikes, the hydrogen is converted back into electricity—enabling around-the-clock power in any setting.

How It Works

Our Power-Plant-in-a-Box™ seamlessly combines solar power generation with our Energy Conversion System to deliver uninterrupted, low-cost electricity—day or night, in any environment.

1. Harnessing Solar Power
The system captures energy from sunlight, instantly powering electric loads such as EV charging stations. This ensures immediate, on-site usage of clean electricity.
2. On-Demand Energy Conversion

When production exceeds demand, surplus electricity is converted into hydrogen and accumulated in secure vessels.
3. Reliable Power Around the Clock

When solar production dips, hydrogen is reconverted into electricity to keep everything running smoothly and resiliently.

By integrating these steps into a single, modular system, Power-Plant-in-a-Box™ removes the volatility of solar-only setups, providing cost-effective, zero-emission energy wherever it’s needed most.
