The 230V appliances on board are microwave, larder fridge, tv, DVD/amp. Apart from the fridge, the other items are intermittent use. On the roof we have 2 x 120W solar panels feeding through a 20A MPPT controller. Overnight I turn the inverter off and the A+++ insulated fridge stays cool enough. We find the solar panels and 2-3 hours cruising a day keeps the batteries upto 100% on the meter. Over 6 years of leisure use we have found this an acceptable compromise for battery usage. At their age they may be due for replacement soon. The benefit of a wide beam is all that roof for solar panels! So I think would worth investing for off grid usage eventually. I leave my fridge on all day and night, also the inverter we cruised between 3 and 4 hrs a day and find that the batteries are normally as full as they will get when we stop. We also use an electric kettle in summer and a coffee maker but no microwave Link to comment Share on other sites More sharing options...
