GridGap For Boat And Shore Power Users

On a boat, the power question is rarely just battery size. Shore power, charging windows, available mounting space, ventilation, and marine installation constraints all shape what is realistic.

Start with shore-power assumptions

GridGap is useful when you want to compare docked charging with more independent onboard use. In many boat projects, grid charge hours maps naturally to the shore-power window you expect to have.

Be realistic about solar space

Solar assumptions need a reality check on a vessel. Available area, orientation, shading, and how panels can be mounted may matter more than the theoretical panel count. Use GridGap to test the estimate, then check it against the boat itself.

Where marine reality takes over

Marine installation standards, corrosion risk, enclosure choices, ventilation, isolation, switching arrangements, and onboard safety compliance are outside the final authority of the app. Use GridGap for early sizing direction, then translate that into a marine-safe design process.
