Get the data necessary to design the best system
Why calculate your daily loads?
The daily load calculator is a simple yet informative tool that can show us (and you) critical information about your boat’s energy cycles and how to optimize your systems. These load calculations ultimately dictate solar charging needs, inverter sizing, and the ideal battery bank size & chemistry. The more accurate your data is, the more effective the planning and design process will be, and the more you can enjoy your time on the water.
