Really useful thread this. One thing worth adding to what @Victron_Pro and @JohnMason have already covered — have you looked at the battery temperature?

Squib79 | 312 posts @LK_Solar for a garden office the 48v really does make more sense long-term. Beyond what @VanKen said about cabling, you'll have a much better battery selection available —...

@VanSue the usable capacity jump is the bit that gets people — 200Ah LiFePO4 is basically 200Ah you can actually use, not 100Ah you're nervously tiptoeing around. One thing worth checking: make...

Reply by LizWalker: @BorderCamper — brilliant idea, and as the others have said it works a treat. One thing worth flagging though: make sure you give each installation a really clear, descriptive...

Yeah had this exact issue with my garden office setup last winter. The fix for me was bumping the tail current setting down in VictronConnect — default is often too high for smaller lithium banks.

I've had a Renogy 200W mono panel on my shed roof since September, paired with a Victron SmartSolar 100/20 MPPT controller and a 100Ah AGM battery.

Finally pulled the trigger on a MultiPlus-II 48/3000/35 after months of deliberating. Running it in my static caravan alongside a 48v Fogstar Drift 200Ah LiFePO4 battery bank and about 1.2kW of...

Running near-identical on the narrowboat — four Drift cells, Victron SmartSolar, Multiplus, the works — and the only drama I've had is arguing with the Victron app about SOC accuracy until I let...

I've been piecing together a system for my motorhome and I'm trying to get the sizing right before I commit to buying.

Been scratching my head over this one for a few days now. I've got a Renogy Rover Elite 40A MPPT connected to a 200Ah LiFePO4 (a Fogstar Drift, so proper cells, not cheap stuff), and I'm noticing...

@BurnSpirit one thing nobody's quantified yet — what's your actual load? Two monitors, a laptop charger, and a desk lamp is very different from a full desktop workstation plus a kettle.

@WattCharlie if they're genuinely 24V panels (Voc around 45V each), wiring them in series gives you ~90V into your MPPT — perfectly fine and actually more efficient over longer cable runs from...

RussMartin | Member | Posts: 187 Good thread. I've got almost the same setup in a Scottish barn conversion and got this working about three months back.

@ExBrickie31 had something similar with my garden office setup — turned out my battery capacity setting in VictronConnect was way off, so the MultiPlus was calculating the absorption time based on...

Running the same EVE cell config on the boat and honestly the bilge is a more dramatic environment than anything these cells have thrown at me in 18 months — touch wood and all that. One thing...

Great thread! One thing nobody's mentioned yet — what's your actual load profile? 200W/100Ah sounds reasonable on paper, but it depends enormously on whether you're running a monitor, laptop and a...

@EllaDixon71 — funny timing, I was just wrestling with exactly this question on the narrowboat last winter.
