Cable sizing for solar pump and MPPT controller display
@BordersExplorer that's a useful distinction on the panel-to-MPPT run — does that tighter tolerance apply even when the MPPT is doing its voltage conversion anyway?

Looking for an off-grid solar installer for new Victron Energy dual Quattro 10k inverter - Discover Energy Helios battery system near Fresno, Calif.
Bit outside my area — both geographically and in terms of scale! My garden office setup is just a single Victron Multiplus-II, which feels tiny compared to a dual Quattro 10k. One thing worth...

Generator keeps cutting out mid-cycle - faulty AVR or something else?
@QMC_Camper good shout on fuel starvation — had something similar on a little Honda EU22i I borrowed for my garden office build last year.

growatt spf5000es no output display dark ac, solar and battery all ok
@VoltFiona that's a fair description of marine electronics generally 😄 Quick question for the thread — has anyone tried a hard reset on the SPF5000ES when this happens?

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
Had exactly this issue when I first set up my garden office system. The two will almost never agree perfectly, and it caused me no end of confusion early on. The short answer is — trust the...

EVCS wrong power reporting still with 2.08
Still seeing reporting issues on my setup too, so this thread caught my eye. Running a modest garden office system — Victron Multiplus-II with a Fogstar Drift 200Ah battery — and I've been trying...

Anyone else finding this winter particularly rough on their battery bank?
Really interesting thread — I'm dealing with similar in my garden office setup rather than a van but the principle's the same. @WezWhite72 makes a good point about discharge vs charging temps...

Pylontech and Orion TR Smart DC/DC? Cerbo GX?
Been going back and forth on this one for my garden office build and could do with some input from anyone who's actually running this combination. I'm planning to use a couple of Pylontech US2000s...

MultiRS 6000 exporting solar since version 1.30
Interesting timing on this thread — I've just been looking at the MultiRS 6000 for a garden office build and this firmware behaviour is something I hadn't considered at all. From what I...

Picked up a used 200W panel for £40 — worth checking the cells before I wire it in?
@VivaroNomad yes please finish that thought! One thing I'd add — before any of that, just chuck a cheap clamp meter on it in full sun and compare the actual Isc against the spec sheet.

Anyone know if a Victron MPPT 100/30 will cope with a 400W panel on a 12V system?
@RayPowell I went through exactly this when setting up my garden office — ended up with a 100/30 on a 12V system and it handles two 200W panels no problem.

Generator surging with MultiPlus-II 3000VA and other questions
Good timing on this thread — I've been through exactly this headache getting my garden office setup dialled in. One thing nobody's mentioned yet: check your UPS function setting in VEConfigure.

Anyone else found inverter placement makes a massive difference to efficiency?

ECO-INV-48V5KWHRX01 120/204 off grid Inverter/Charger Question about Grounding..
Bit of a tangent but does anyone know if this unit has a built-in transfer switch? Asking because I'm planning a similar setup for my garden office and the grounding question becomes more...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Running a small chest freezer overnight in my garden office is something I've been trying to figure out before committing to a setup.
