Why I abuse batteries was: trojan battery cycle [RE-wrenches]

HI John,

I guess I said to poorly, but was trying to convey the efficiency of  
battery charging of the generator/inverter/charger combo.

For example the sunny Island will do a different charge every 14  
days, but for some customers that could be 14 cycles or others none  
at all.

So what I'm suggesting is a fully adjustable for days between  
different types of charging  ( 80% full, 90% full and 100% full?)

Could we also get a program that scheduled the genny to start at some  
program time, but wasn't fixed.  So if its within some parameter,  
start at say 6pm ( when the evening loads are starting) but if some  
lower voltage occurs before that then start then.
Right now there is no way to do this that I know of, but this can  
improve the efficiency as many generators are sized to provide full  
charge power + extra for the house loads and then saving charge  
cycles on the batteries.

Does that answer your questions

As this thread has brought up  what I have been wanting for some time  
is this idea of a smarter
