After years of messing about with AGM and then moving over to lithium, this is something I've spent a fair bit of time dialling in on my motorhome setup.
For LiFePO4, I run my Victron MultiPlus...
Worth adding from my motorhome setup — I've confirmed this affects the SmartSolar 100/50 on 3.80 as well, so it's not isolated to the smaller units.
One thing worth checking: if you're polling via...
Keeping a close eye on this one, even from across the pond. The principle of utilities imposing fixed charges specifically to disincentivise solar adoption is something that's absolutely rearing...
Been running a 24V/1200VA in my motorhome for about three years now and the toroidal transformer is genuinely one of the better bits of engineering in the unit.
@TracyAllen is absolutely right about tail current, and it's worth being specific about why it matters for top balancing.
When the MPPT exits absorb early due to tail current being met, the cells...

@Del72 something nobody's mentioned yet — your Fogstar or whatever lithium you're running will absorb both inputs simultaneously without issue, but the real gotcha is...
@AlexPalmer60 worth doing a proper load audit before assuming 100Ah is enough long-term. Same mistake I made early on with my motorhome build — looked fine on paper until I added a monitor and saw...
Really worth thinking carefully about your charge controller setup before committing to a turbine, @Doug1981.
Picked up a 200Ah Fogstar Drift last spring and overall I've been dead impressed — solid build, good comms via the app.

@AndyGraham interesting setup — my experience is mostly motorhome-based but the winter energy maths translates directly.
The killer issue in a static installation like yours is that you can't...

@TracyRobinson The EF2000iS pairs beautifully with a Victron MultiPlus if you've not already wired it that way — the PowerAssist feature means the inverter/charger only...
The lads are spot on about measuring first. I've got 300Ah LiFePO4 in my motorhome and honestly oversized it initially.
The usable capacity thing is absolutely critical, and it's worth drilling into why it matters so much.
