System Efficiency Comparison

Startup:
Turn system ON. Generator starts/stops automatically when batteries are low.

Lithium Battery system powers ALL SYSTEMS:
Lighting, hydraulics, water pumps, USB sockets.
AIR Heating powered by diesel tank & battery.
240v Sockets, kettle & microwave.

Generator for lithium battery charging ONLY:
When batteries are low the generator is used as a battery charger. Victron systems manage the power flow.

Hot water on demand:
An integral storage tank keeps water hot for up to 4 hours (generator power for 4 minutes)

*Based on 10 hours per day for 260 days, 80 days in winter mode and 180 days in summer mode.
Each day is a typical usage day.
Solar panels achieve maximum output in direct sunlight, but they work in normal daylight and cloudy weather too. The amount of power a solar panel or charging kit generates in cloudy weather will be lower compared to direct sunlight. Also the positioning of the cabin will affect the solar charging of the batteries i.e. under trees, etc.
This assessment doesn’t take in consideration the usage of the hydraulics. This assessment is guidance only.
