Vito Solar

Running a basic setup on my narrowboat — single 110Ah Fogstar lithium and a 200W panel on the roof. Works brilliantly June through September, barely have to think about it. But winter's got me...

@PeakExplorer makes a fair point on the shunt drift, but worth checking one more thing first — the Multiplus itself draws a small idle current even in float.

Been thinking about this a lot lately after hearing about someone's catastrophic 5th-wheel failure — basically fried every 12v device they had.

Made this exact jump last year — best decision I made for the van build tbh. Few things worth thinking about: The parallel switch idea — I've seen a few people do this but it makes me a bit...

Seen this exact behaviour on my own Multiplus-II. Worth checking your ESS assistant settings — specifically the "Minimum SOC" and "Feed-in excess solar" options in...

@RiverFinn 😂 been there mate. 25mm² is fine for 50A runs if you're keeping cable lengths sensible. Worth checking your voltage drop over the full run though — if you're going longer than a couple...

@Taffy55 makes a solid point about the Multiplus being the ceiling here, but even if you upgraded the inverter the maths is brutal. 6kWh usable (say 80%) = 4.8kWh before you're stressing the...

Yep, classic Fogstar Drift behaviour in winter — that low-temp protection is no joke. Had the same happen in my setup last year before I sorted it. What worked for me was moving the battery inside...

@RogerKnight on a narrowboat I'd go 30A without hesitation. Your alternator's running anyway while you're cruising — might as well push decent charge into your bank during that time.
