The EFOY fuel cell – the perfect partner for your solar system
If your mobile home already possesses a solar system but you’ve noticed that it isn’t providing you with enough power on rainy days or in the autumn, then the EFOY fuel cell is the perfect solution for you.
EFOY fuel cells and solar cells – Power you can depend on in any weather
Working together as a hybrid, EFOY fuel cells and solar cells combine the best of both technologies.
- In nice weather, the power comes from the solar cell
In a fuel cell/solar cell hybrid, the solar module alone produces electricity. The EFOY remains in standby mode. - In bad weather, darkness or in winter, the power comes from the EFOY fuel cell
Solar cells cannot deliver enough current to the battery during bad weather. EFOY fuel cells are equipped with a built-in regulator that connects directly to the battery, monitoring its voltage continually. If the voltage dips below 12.3 volts, the EFOY fuel cell cuts in automatically and recharges the battery. It then automatically shuts itself off and resumes standby mode. - Economical to operate
A fuel cell/solar cell hybrid is an economical solution. Power from the sun is free. You’ll incur fuel costs only if there’s no sunlight.
Two ways to combine the EFOY fuel cell into a solar system
You can:
- retrofit the EFOY fuel cell as an adjunct to your existing solar system with a minimum of effort or,
- purchase a complete intelligent fuel cell/solar combination for your mobile home from the Büttner- Elektronik company (German Version).
You’ll have reliable electrical power anytime, anywhere, with a hybrid combining the EFOY fuel cell and a solar cell
