Same things we do now. Lighting, yes. Communication. Power tools. Pumps. Winches. Automation. GPS should last a good while too.

A lot of those heavier duty things you mention require three phase power, which is very difficult and expensive to handle independently without the grid to support you.

Do they really require it? Or do they just currently use it because it's convenient with the grid? In an off-grid scenario, you probably wouldn't use AC power for anything. DC motors will serve perfectly well for the "heavy duty" applications.
