OP says he got the IQ4 with his DLS-X, but the Iota blurb says to get the IQ4-X to go with it. Not too clear what you get with the X that is not in the earlier version. Some mention of a "fourth stage" shot of destratification every so often (how often?) during storage.
I did get the IQ4-X as that is the only one that works with the -X charger. As far as functionality the only difference between the -X and the regular IQ4 is the bulk charging voltage as best I can tell. The unit also directly mounts to the charger versus being plugged in via a phone type cable.
The one thing I do like about this converter is the ability to connect #2 AWG cables to the DC output. With the large cables and having a Bus bar connected to my batteries a few feet away with 2/0 cable, there should be minimal voltage drop.
The battery charging should mostly be done with the solar charge controller which is a Victron MPPT 100-30. This controller is programmable so I can fine tune any parameter I want. I'm primarily adding the Iota because now is the time to do it since all of the equipment will be mounted on a panel in my pass thru and I want to get a better charge from a generator if solar if falling behind than the WFCO that is 25' away will give me.
