hey matt,
a follow up note here,
with your last post we see that with the low capacity automotive batteries we came up to charge quickly and had less "run time" which had less capacity and therefore had less to recharge.
we changed over to nicer batteries with more capacity meaning more charge time needed but find we have more "run time". our available charge has not changed but we may have changed our "run time" habbits?
we have seen folks use their inverter alarm/low voltage cutoff to determine their "run time" and the results are always the same..bad. say it ain't so.
these little systems are fun and you will get a feel for how yours behaves after a very short time and know just how much is going in and out. one of the best things i did early on was to get a trimetric 2020 monitor.
it's all good fun, even the having trouble part!
kind regards, dave kb1mzf
