Truth, wayne, AKA Rimmer has told several lies in this post. Most of
them stemming from the fact that he has proven time and again that he
did not design his system. He has already conceded that he has a
300,000Ah+ over production and a 5000Ah short fall per year, his
claim is that this is normal. None of his above figures can be taken
seriously. He cannot provide any coherent number for his system.
Beware, Rimmer is a fraud who despite claims of having designed his
system and having built his house has yet to provide any compelling
reason to be believed.
A point in case is the last paragraph in which he claims that adding a
transformer some how has added input and storage capacity to a system.
