Classic site hookup issue. Worth checking your AC input current limit is set correctly in VE.Configure, but also look at the PowerControl and PowerAssist settings — these are what actually manage...

Cerbo_Geek | Posts: 1,204 | Location: Array One thing nobody's mentioned yet — with a 13A supply you'll want to set your input current limit in VictronConnect (or via a GX device if you're running...

I've ended up in a bit of an odd situation where I've got a 200W panel on the shepherd's hut (feeding a Victron MPPT 75/15 into a pair of 100Ah Fogstar Drift LiFePO4s) and a separate 175W setup on...

I've been running a small off-grid setup at my static caravan in Wales for about two years now — 400W of panels, a Victron SmartSolar 100/30, and a 200Ah lithium bank.

Mark1970 | 312 posts Same situation here — Midlands, so not as brutal as you lot further north, but December and January are still pretty grim for solar.

BayJason | 634 posts | Array @SD_Sparks makes a fair point about Scottish solar yield — worth pulling actual irradiance figures for your postcode from PVGIS rather than guessing. One thing I'd add...

Ha, @ForestDaz makes a fair point there @Keith1981 — the 2x120V is very much the wrong side of the pond!

@MXM_OffGrid is right on the physics but there's a practical win people miss — a proper MPPT like the Victron 75/15 will actually let you set lithium charge parameters correctly.

@NicolaTaylor72 great question on tilt — yes, absolutely worth doing. I'm in the East Midlands and I swapped my panels from a fairly flat 15° to around 55-60° in November.

Been having a frustrating few weeks with my 280Ah LiFePO4 build in the van. I've got a JK BMS (the 200A active balancer version) paired with a Victron SmartSolar 100/30, and the Bluetooth on the...

Robbo | 📍 Array | Posts: 203 @Curly7 Quick question before you go down the rabbit hole — what's your battery bank sitting at when it cuts out?

WildWanderer | 847 posts | ⭐ Regular Contributor @CopperWelder That's a clever setup actually! I did something similar last winter in Wales, though I was only juggling a small cabin alongside the...

Just to flag something @CurrentAffairs — with 2x 200W panels in series, your Voc could easily push 50V+ depending on the panels.

Really enjoying this thread! Living aboard a 58ft cruiser stern on the Oxford canal and switched to 200Ah of lithium (EVE cells, DIY 4S build) about eight months ago.

Great thread! @SmartSolarNerd and @XO_Sparks have covered the direct charging side well. One thing I'd add from my own experience — if you're running the EU22i to charge via an inverter-charger,...

@RKE_Builds nice panel score. Running a similar Victron 100/30 on the narrowboat with 400W of mixed mono panels — nothing as tidy as your 2S2P but it works. What I've noticed is the Victron's...

@MarshPete worth clarifying the terminology here since it's causing confusion in threads like this regularly — "B2B" (battery-to-battery) and "DC-DC charger" are the same...

Eight months without crying at an electricity bill is basically a spiritual achievement at this point. My tiny house setup taught me one thing: the battery is where budgets go to die — spent more...

Decent write-up @GlenKelly. Be interested to hear what battery chemistry you went with and whether you sized it right first time or had to add capacity later. My van build taught me I almost...

Just to add something nobody's mentioned yet — with a single 100W panel you're not going to see massive gains from MPPT in terms of raw harvest, maybe 10–20% in good conditions.
