Gerry underwood Posted July 2, 2020 Report Share Posted July 2, 2020 As per my last post. I believe that I have calculated correctly and it would appear that we are at about 90AH per day. We are not going to be using the kettle, microwave or toaster. We have had a quote for a 12V 640W Complete Boat Solar Kit With Mono Panels. Works out at £750 for everything.

Being pedantic it’s actually 1080Wh. But I agree that you should be good for 8 months of the year. But don’t be surprised when your controller never shows anything like 640W flowing into the batteries. Link to comment Share on other sites More sharing options...
