Swapped out the old Victron for a Sterling on my narrowboat – anyone else done this?

Interesting swap to make — what was the reason for ditching the Victron? Reliability issues or just cost?

I've been running a Victron MultiPlus on my narrowboat for about two years now and touch wood it's been solid, but I've heard mixed things about Sterling kit. Some people swear by it for marine applications, others say the support is hit and miss compared to Victron's ecosystem.

The main thing that keeps me on Victron is the VRM portal and how everything talks to each other — MPPT, BMS, inverter/charger all reporting back to one app. Does Sterling have anything comparable these days? Last time I looked it felt a bit more old-school in terms of monitoring.

A few things I'd be curious about:

• Alternator charging — did you fit one of Sterling's alternator-to-battery chargers alongside it? That's where they seem to have a strong reputation
• Shore power performance — any difference in how cleanly it handles the transition?
• Noise levels — my MultiPlus is pretty quiet running at the stern, wondering if Sterling is comparable

I'm also half-thinking about adding EV charging capability at my mooring at some point, so interested in how well the Sterling handles higher loads if you've pushed it.

Not trying to talk you back to Victron — just genuinely curious whether the swap was worth it in day-to-day use on the cut.

@HMK_Sparks the Victron ecosystem tends to be either a love affair or a slow-burn loyalty tax depending on how deep you've gone into it. I run a MultiPlus in my van conversion and as emergency backup at home — the Cerbo GX integration alone kept me from ever straying.

That said, Sterling make genuinely solid kit, very much the unsung British alternative. Their battery-to-battery chargers are near unbeatable for the money.

The real question is whether the original poster was running Victron in isolation or as part of a wider VRM monitoring setup — because that's where walking away gets painful. Stripping out a Cerbo and SmartShunt just to save a few hundred quid on the inverter-charger feels like false economy to me.

What's your alternator charging situation like on the narrowboat? That'd influence my thinking considerably.

@HMK_Sparks two years in is actually the interesting inflection point — that's roughly when you've got enough data to know whether the Victron ecosystem is genuinely working for you or whether you're just feeding it configuration time.

I run a MultiPlus-II in my camper and the honest truth is the VE.Bus rabbit hole is real. Brilliant kit, but every firmware update feels like a small gamble.

Sterling's reputation on narrowboats specifically is worth noting though — they're a British company, their Pro Charge Ultra chargers have been on working boats for decades, and getting warranty support without shipping units to the Netherlands is genuinely useful when you're living aboard.

What was the actual trigger for the swap? Curious whether it was a specific failure or just accumulated frustration with the software side.

Not really my territory (narrowboat vs. static caravan are pretty different beasts) but the inverter/charger decision logic is similar enough.

One thing worth considering before any swap: Sterling kit is solid for marine specifically — their chargers are designed with alternator protection in mind which Victron historically required extra bits to achieve properly. If you're doing a lot of engine-charging on the cut, that's actually a meaningful advantage rather than just brand loyalty either way.

That said, if you're already two years deep into the Victron ecosystem with MPPT, Cerbo, shunt etc., the integration cost of switching is real. You'd essentially be running a hybrid system or ripping everything out.

What's your current monitoring setup? That's often the hidden anchor that keeps people on Victron longer than the inverter itself would justify.

@HMK_Sparks two years on a narrowboat with a Victron is basically a relationship — you've survived the honeymoon phase and you're now just waiting to see who blinks first when something goes wrong at a rural mooring with no signal and a dead bow thruster battery.
