I run the same set up, though without sg. I just set the victron up from pc, as per instructions. I can't remember what I set float at, but according to my bmv, I hit 100% with Genny. Perhaps your BMV is lying. They tend to do that. Do you check the tail current or specific density or anything else to determine 99.99999%?

No, I don't bother doing anything (other than water them) until the batteries get knackered. Then I get new ones.

So long as you keep your batteries between 50% and 100% (ish) they will last longer than letting them drop consistently under 50%. Basically lead acid batteries don't like being left empty for too long. Trust me, I know nothing.

Are you getting a cut for being the middle (wo)man? I answered all this on the other thread! Or just trying to tempt a certain person out of hiding... neither really, i have a genuine question so thought i would ask here instead of over there, i can ask there if you prefer lol anyway it will go to 100% if i put the inverter into equalization mode but thats a pita to do Sorry I thought you were asking the question on behalf of someone else. No on here is fine. Good even! So, starting again, the Victron has a feature called "adaptive charging" which is supposed to make it go to float intelligently so as to avoid overly gassing the batteries etc. I don't have one but by all accounts adaptive charging is pants. You can deselect it by means of the DIP switches I think, or more easily using a PC. The whole point of float is to allow the charger to be left plugged into the mains 24/7 without overcharging the batteries, however when you are charging from a genny you want the charger to work as hard as it can until the batteries are fully charged and the you want to turn off the genny. There is no point in running the genny when the charger is in float. Therefore if you always charge from genny I would adjust the float voltage to match the other voltages (effectively meaning it doesn't have a "float" mode) so that you are never pointlessly running the genny with the charger in float. if you do sometimes plug the charger into shore power and leave it on, I'd suggest just changing from adaptive charging to fixed absorption. That way it shouldn't go to float before the batteries are full.

That way it shouldn't go to float before the batteries are full. yes i get that, so what you are saying is by doing it that way i turn the genny off when the batts are charged and not be led by the inverter telling me its in float and to turn the genny off. i never use shore power so that wont be a problem. will do that this weekend and let you know how it goes, although you probly know the result already, thanks for that.

Correct. And no probs. Have you changed the settings with the DIP switches before? I've never had hands on with a Victron and do find the instructions confusing so if you struggle to get it to work don't be hard on yourself, it IS confusing. Using a PC is much easier but of course you need the right lead.

I got flogged off with used batteries a few years back. The give away sign was getting acid burns when unwrapping the bubble wrap over the batteries. Also, the acid was supplied in old anti-freeze containers. Just saying.

There are two buttons that depress to alternate between the set up sequences.

Using a PC is much easier but of course you need the right lead. The dip switch system is pretty easy to use when sat in front of them. There are two buttons that depress to alternate between the set up sequences. The bit I don't quite get is that you have 1 bank of DIP switches to change 2 sets of parameters. So let's say you had previously set up "sequence 2" and wanted to change 1 setting on "sequence 1", you would have to change all the DIP switches from "sequence 2" to match "sequence 1" except for the one switch you wanted to change, then press the appropriate button. Is that correct? It just seems unfortunate that you have to review and set every setting in that sequence just to change 1 setting.

nice to see you Gibbo and welcome, i hope we don't bore you too much It seems unlikely with the amount of un-moderated arguing and insulting that goes on here. I like it. It was the moderation that ruined that last forum. Too politically correct. I guess they were simply too scared of being called gay or Pikeys.
