20A Off-Grid Charging System Package

PART NO. 40-256

The CTEK 20A Off-Grid Charging System charges your battery bank from several sources, prioritizes connections, and looks after the battery so it will not become completely flat. It also optimizes charging while driving to give you more time off-grid. CTEK gives you full control with the battery monitor that shows you how many hours are left before the battery bank is empty. With this system, you can sit back and relax because you know how long your battery will last.

20A Off-Grid Charging System Package Includes:

1 – Part# 40-186 - D250SA Dual – DC/DC onboard charger

1 – CTEK Battery System Monitor (not available separately)

“Having owned several of another ‘popular’ brand of charger, the CTEK is far and above superior in every possible category. WELL worth the miniscule additional cost. ”
