I once worked it out that Wales gets enough rain to provdie for the whole population of the World!!!
So you are using the quoted pump rate of your pump to work out how many litres rain there was? mmm... not sure that I would trust the pump manufacturer to quite that extent!
The point I was trying to make was 1000L will be the extreeme rather than the rule.
If your pump takes 1 hour to drain this and draws 6A then your implication is each day you need to put 6Ah of juice back in the battery.
In reality the way the weather works you might have two days of high rain fall, two days of moderate rainfall (maybe 1/4 the demand) and then say three much drier days. So in a pretty bad week you might draw 15 Ah rather than over 40 if every day was actually super wet.
