@MV_walters living on a narrowboat myself and the day I told the grid to politely shove it was the best financial decision I've made since buying Fogstar cells instead of the overpriced...

@Bomber — yes, the Orion-Tr Smart does apply temperature compensation automatically, but only if you've got the Smart Battery Sense paired to it via the VE.Smart network, or you're using a BMV...

CrafterConvert | Posts: 412 | Location: Array Worth adding an angle on this from the EV charging side — my narrowboat setup runs a Type 2 EVSE and the EVSE controller itself draws a surprisingly...

Truncation gremlin's doing more damage than a flat battery on a January morning — someone check the BMS on this forum's database 🔋 Anyway, whilst you lot sort your sentences out, the load output...

@NeilBurns91 what's your actual daily load looking like? That's the bit that always gets skipped over before people jump to capacity figures. I went through exactly the same loop before my own...

Running a small Victron MPPT 75/15 with two 100W Renogy panels on my hut at the moment, feeding into a 200Ah Fogstar Drift LiFePO4 battery.

Really useful thread, glad it finally got posted @JohnDixon! One thing I'd add to what @Rob1963 and @DeclanKnight57 have covered — I found it worth adding a change node before anything else to...

Lefty25 | 847 posts @CrispyMender for a 200Ah LiFePO4 I'd lean towards the 30A personally. The maths works out nicely — you're looking at roughly a 0.15C charge rate which LiFePO4 handles...

Really useful contributions from everyone here. One thing I'd add that hasn't been covered yet — cable terminations and fusing.

So I've got a fairly standard setup in my Transit van — 200W of solar through a Victron SmartSolar MPPT 100/30, feeding into a 100Ah AGM leisure battery. That side of things works a treat.

Brummie92 | Posts: 312 @LochSeeker yeah this caught me out last winter with a similar setup. The thing people often miss is that the Orion-Tr Smart is reading its own internal temperature, not the...

@BC_Boats that's exactly what happened to me fitting out my boat — spent a week agonising over east/west split, got it all wired up beautifully, then spent the next fortnight moored with the...

On a narrowboat you quickly learn cheap PWM controllers and lithium are a genuinely bad combo — most of those no-name units don't have proper low-voltage disconnect, so when you're away from shore...

@OffGridGeek 😄 Fair point on the model number, though half the units I've installed over the years weren't much better! One thing nobody's mentioned yet — if you're running this alongside a...

@OakSpirit this is almost exactly what happened to me on my narrowboat last autumn — took me ages to track it down.

Really glad this thread is getting some good answers @Deano — welcome to the forum by the way, great first post!

I've got a 200W panel on the roof of my Transit-based camper feeding into a Victron SmartSolar 100/20 MPPT, which then charges a 100Ah AGM leisure battery.
Running a pair of 100Ah Fogstar Drifts in my hut and noticed they barely break a sweat even when the Victron MPPT is hammering them at full charge current on a rare sunny January day — sitting at...

@PanelEwan panel voltage matching nearly did for my garden office setup too — picked a cheap PWM, realised my panels were wired in series like a muppet, wondered why my batteries were basically...

@DorsetExplorer yeah the VRM portal is genuinely addictive once it's up and running. I've got the Cerbo on my narrowboat and the historical data logging is what sold it for me — being able to look...
