EFOY Pro + Solar cells – The best of both technologies

If the weather’s good, solar cells provide the power.

If the weather’s good, only the solar module generates electricity in a fuel cell/solar cell hybrid. The EFOY Pro remains in standby mode and solar generation keeps fuel consumption low.

In bad weather, darkness, or winter, the fuel cell kicks in.

Solar cells will not deliver enough current to batteries in bad weather with the result that voltage drops. Once the battery level dips below a certain threshold, the fuel cell cuts in automatically and recharges the battery. It then reverts automatically to standby mode.

Inexpensive

An EFOY Pro/solar cell hybrid is inexpensive. Costly over-sizing of solar panels is no longer necessary, while battery capacity can be kept to a minimum. Heavy, expensive banks of batteries are a thing of the past.

Cost-effective operation

An EFOY Pro/solar cell hybrid is also inexpensive to operate. Fuel costs for the fuel cell only occur when the sun isn’t shining. What matters most though, are the personnel and logistics savings that result from not having to travel on site to replace batteries.

Easy to integrate

The Plug & Play feature allows you to combine the EFOY Pro easily with new or existing solar systems. The EFOY Pro connects to all common 12-volt and 24-volt batteries.
