Finding reliable energy for remote applications can be a real challenge. Batteries are heavy and go dead quickly, so they don’t provide a long-term solution. Generators are noisy, dirty and require lots of maintenance. The default solution is solar modules. Once installed, they deliver electricity courtesy of the sun. There’s one problem though: when the weather’s bad, power production drops dramatically and devices may stop operating. That’s why solar modules often need to be oversized and equipped with large batteries to make sure that they continue producing power even in bad weather.

100% reliable power around the clock, in any weather

The EFOY Pro/solar hybrid combines the best of both fuel cell and solar technologies.

In a fuel cell/solar hybrid system, the solar module provides all the power when the sun is shining. The EFOY Pro remains in standby mode as long as the sun delivers free energy.

In bad weather, solar cells can’t deliver enough power and so, battery voltage drops. Once the charge falls below a certain threshold though, the fuel cell automatically cuts in, recharges the battery, and then returns to standby mode.

A hybrid system consisting of the EFOY Pro and a solar system offers cost advantages. You no longer have to construct oversize solar panels and you can keep battery size to a minimum.

An EFOY Pro/solar hybrid system is also economical. When the sun is shinig, less fuel is needed. More importantly, though, you no longer have to replace batteries. That means lower personnel and logistical costs.

Easy to integrate

Use plug and play to integrate the EFOY Pro into new or existing solar systems.
