the size of the battery bank is much more to do with what you need to take out of the system, rather than what you use to put it in! :wink:
If you're drawing 70amp/hrs in a day, you'll need ten times that (700amp/hrs), minimum battery bank size, as you shouldn't aim to take more than 10% out in a day! This isn't me trying to flog you lots of batteries - it is a pragmatic "rule of thumb" to ensure reasonable and economic battery life and performance! :geek:

sorry Martin I'm a technoidiot. that is a good rule of thumb to remember tho. thanks.

so, about Sammy (i've already given him a nickname :0).. would he do the job for us.. minus the fridge? (I'm planning to experiment with some low tech fridges)

what can you tell me about the EMF's coming off the equipment? Have you ever measured that?
