Your 8kW will barely dent a proper EV charge without battery buffering — tried it on the narrowboat, watched the MultiPlus have an existential crisis.

The Drift's real strength is the BMS doesn't have that paranoid voltage-cutting-out phase that plagues cheaper units — actually lets you use the battery rather than just admire it through the...
Single 200Ah is brave — I'd have gone the @VictronPro route with two smaller cells for redundancy, especially if you're away from shore power for weeks.
Got bifacials on the narrowboat and they're a game-changer when you're against a light-coloured bank, but honestly?
Proper crimped connections are your mate here — dodgy terminals will have your Cerbo throwing phantom alarms at 3am like a hyperactive smoke detector.
The real question is whether you're actually adding 7kW of simultaneous demand or just hoping to charge an EV someday—massive difference on your battery bank, as @LiFePO4Nerd rightly points...
The cold weather point @LochLover raises is the real gotcha — I've seen my narrowboat's Starlink PSU efficiency tank by about 15% below freezing, which catches most folk off guard.
What actually...
The real test is what your panels actually do in British winter grey, not the spec sheet fantasy. PWM wastes power when your panel voltage sits higher than battery voltage—could be 20-30% on a...
Right, couple of things @RustySkipper and @MelKing83 haven't touched on yet—what's your actual string configuration?

Had a Renogy DCC50S melt a connector in my static caravan—turns out it doesn't like poor cable termination like the Victron does.
ModBus TCP is genuinely the gateway drug to proper system management, but I'd add one thing nobody mentions: keep your HA instance and Victron on the same network segment or you'll spend hours...
Mate, the irony of us spending thousands on perfect dark setups then getting blinded by a white forum at 2am is chef's kiss. Meanwhile my Victron display's doing the sensible thing in night mode.
The real killer is BMS incompatibility — each brand's balancing algorithm works differently, so you'll get voltage drift across your parallel strings and one battery doing all the work while...

The real differentiator for me was the GX integration — the II plays nicer with Cerbo/Venus setups if you're already invested in Victron's ecosystem.
My caravan's got so much sun exposure the panels generate more leccy than I can store — genuinely had to ask Victron if my Multiplus was just being dramatic or if I'd actually overprovisioned.
