Stay Powered on the Water: Pair CTEK D250SE with a Solar Panel for Onboard Charging
For boaters who love exploring the open water without giving up the comforts of home, reliable power management is key. With the CTEK D250SE paired with a solar panel, enjoying extended time at sea is easier than ever. This combination ranks high among the most effective boat onboard charger solutions – offering seamless, dual-source charging whether you’re docked or on the move.
The CTEK D250SE is designed for those who want to power their boat’s service battery when you don’t have shore power. It draws energy both from the boat’s alternator (also known as a smart alternator) and solar panels, making it the ideal charging solution for off-grid marine adventures. With its fully automatic 20A output and built-in temperature compensation, the D250SE keeps your service battery in top condition, even in varying weather.
Charge While You Cruise
One of the standout benefits of this system is its ability to charge your service battery while on the move. Whether you're sailing to your next fishing spot or cruising the coastline, the D250SE takes power from both the alternator and your solar panel in parallel – ensuring consistent energy delivery without needing to stop or plug in. It's an ideal feature for those who enjoy uninterrupted power for fridges, lights and navigation systems.
