Thanks. Re the leisure battery, the fact that the Ocean comes with two is only a benefit if you expect to be without a hook up for more than 3-4 days? And sorry what does trickle charge mean? if you were driving for say an hour, very roughly speaking, what % of the battery would recharge? thanks
That is quite a technical question, and one that I cannot answer.
What we have done is put two 100 watt solar panels on the roof. We use these to charge the leisure battery, and hope that it will give us a year round off grid solution - however, it is almost completely untested. We shall be rigorously testing it over the next year as we are off on a year long farewell tour of the European Union beginning 5 June, ending June/July 2018. Over that year we hope never to hook up, but just in case, we are taking away with us a 10m hookup cable and Euro socket adaptor. We have been told that solar panels with a good MPPT controller gives an excellent recharge to the battery and mains hookup is not required to keep the battery is tip top condition.
We expect the solar panels and battery combination to:
1. power all internal lighting at night
2. power the compressor fridge 24/7
3. charge iphones, ipads, torches and electric toothbrushes
4. occasional 12 volt TV use
5. power the diesel heater pump when in use
With this setup, it is best to charge items in section 3 during the day rather than at night.
The cost of this setup is £853. As campsite hookup is typically £2-£4 extra per night, solar panels are not an economic advantage, simply a convenience.
