One source certainly can be enough in many cases, but the other sources need to be able to be prevented from doing anything dumb, which, depending on the source happens a lot. If you have a good...

Our homemade mounts are similar to Marko's, but I only used one piece of angle and than a piece of flat stock up that mounts to the side of the solar panel which they said was OK for our panels from...

Most of that test look very normal for AGM charging, including the time to recharge only 22%. By 4 hours you were considerably tapered on amps at 12.1a and at that point the charger timed out of...

It really should reset on tail amps and voltage, as that what matters. It was interesting though that appeared to reset when it 100% in the example given. The defaults in the Victron are way off...

That is the basic premise for sure. The problem comes from the depth of discharge before recharging because the charge efficiency will change as the battery fills so the overall efficiency has to be...

My guess is that for a big battery bank like yours the charge efficiency may be a bit high because you will be in the inefficient slow charging range much of the time. Setting the efficiency may be...

Do you have a charge efficiency programmed in to the Victron? You should expect to always see more amps back in than were taken out due to the inefficiency of charging. On a very low discharge like...

i dug around some and it appears that Interstate uses some non normal chemistry in at least some of the deep cycle batteries. They talk about 14.4v bulk and then 15.5v absorption, then 13.2v float. ...

Yes that is what I mean. .56 amps is like .1% which is way low for wet cells. What shunt and settings do you have in the Victron?


What model # batteries are they?

yep, Bogart knows their stuff, although they also have backed off on defaults because most chargers can't do the charging well enough. It is too bad the charger folks haven't improved things for wet...

The T105s are wet cells so would have totally different charge parameters compared to AGMs. 14.4v vs 14.7v is not a big deal in most cases. If yours are wet cell GC2s, I would do a test to see what...

I am assuming you have AGM batteries? if so, the setting that is generally too conservative is the tail current (return amps, ending amps, float transition amps).


The recommended setting for...
