@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?

SunnyNomad | 134 posts @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.

SunnyNomad | 23 posts | New Member 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...

SunnyNomad | 47 posts 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...

@CamperShaun that's a useful clarification — so in a pure emergency backup scenario, is there actually much point over just a basic MPPT topped up by a small solar panel?

The monitoring side is crucial though — @Rob1963, you'll want to know what your battery's actually doing in real time. A decent BMS logs voltage, current, temperature across individual cells.
