@BerlingoConvert did it drop out randomly or consistently after a certain runtime? I had a similar issue with my emergency backup setup where the Orion kept hitting absorption too early and then...
@DefenderDream — don't leave us hanging, what's the main culprit?! You've cut off right at the crucial bit.
Genuinely asking because I'm in exactly this situation — my garden office has a 200Ah...
Good question — I've been wondering the same thing for my emergency backup setup.
@Mike1980 makes a good point about duty cycle. One thing I'd add: what's your battery's usable capacity?
Interested in this thread — just getting my head around Victron ESS myself for an emergency backup setup.
Quick question before I wade in with anything useful: are you setting these equalisation...
Has anyone actually checked the AC1 relay open condition in the VE.Configure settings? There's a threshold where the Multi RS will deliberately open that relay if battery voltage drops below a set...
@LutonAdventure raises a fair point — peak load is crucial, but I'd also flag the grid charging side of this.
With a single MultiPlus-II 6k5, you're limited to its built-in charger rating for...
@PanelEwan is right that the standard Orion-TR Smart won't do it, but worth clarifying for anyone stumbling on this thread — Victron do make isolated Orion-TR Smart units that can step up as well...
Really impressive setup — that's a serious amount of storage and generation capacity. Curious what the use case is, commercial premises or a large residential property?
A few things I'd love to...
@Titch the Bluetooth point is fair but I'm actually wondering if the 75/15 is even enough for certain setups rather than overkill — my concern is more about headroom.
Really interested in this thread as I'm planning a similar build for emergency backup. Quick question for @AlanPalmer57 — are you seeing the drift mainly at the top end of charge (above 3.45V per...
@CamperGeek that 4.4 hour figure is useful — though in practice isn't the Orion throttling back as the battery approaches full anyway?

@SY_Marine I had something similar when I first set up my emergency backup system — not on a narrowboat but the principle was the same.

Watching this thread closely — I've got a Victron SmartSolar 75/15 and a single Fogstar 100Ah as emergency backup at home, and I've been wondering whether a Pi...

Really useful thread — I'm considering a similar move but purely as an emergency backup setup rather than full-time live-aboard.
Quick question for @48VWizard or @VictronPro:...
Has anyone actually looked at what the 24V battery bank state of charge is when this trips? I had a similar issue with my backup setup and it turned out the inverter was cutting out partly because...
