You can never have too many options for alternative energy charging choices for the DC system on a boat. The EFOY Fuel Cell, which is powered by methanol is perfect for a boater without a generator, who would like to stay at anchorage for a few more days without worrying about draining the boat’s batteries or running the boat’s engine at a low idle to charge the batteries. It may also appeal to the boater with a generator who is tired of the constant noise, vibration and fumes, especially in a tight anchorage or quiet bay.
The EFOY is extremely quiet, can be stored in a cabinet or under seating, has no vibration, is maintenance-free, fully automatic and does not produce emissions so it is eco-friendly. The unit is compact and weighs only eight kilograms (17 pounds).
There are three EFOY models, designed specifically for the marine and RV industry, an 80A, 140A and 210A. The EFOY is by no means a replacement for a traditional generator, its real purpose is to charge batteries. It comes with an integrated charge regulator that monitors the charging status of a 12-volt battery. The EFOY will start automatically when it senses the battery is low and then switch off when the battery is full. When you install the unit, it is important to select the type of batteries you will be charging, such as flooded, gel, AGM or LiFePO4 (lithium iron phosphate).
