Just about the make the move to an off grid caravan. Its in a wooded area so i cant do solar yet. Im taking the plunge on a 3KW inverter genny to give me power at the start. I was going to use it to charge a battery initially as we will have very minimal power requirements.
Do I need anything else appart from the battery (leisure battery, maybe 80 - 120 Ah), battery charger (230v) and genny. How often will I need to do a top up on the battery with very minimal power usage (laptop, LED lights, phone etc.)
