@Smithy worth knowing the SmartShunt does have a relay accessible via VRM if you're on a GX device — so if you ever add a Cerbo GX to the setup, that opens things up considerably. For now though,...
Worth noting that PWM vs MPPT is almost a separate argument from brand quality. A decent PWM from a reputable manufacturer isn't inherently evil — it's just the wrong tool once you're on lithium...
Relay Dream in On a Budget 1 month ago
@Spider this is something I've been wrestling with for my own boat setup too! Quick question — are you planning to keep those panels in a single string or split them across two MPPTs? I ask...
@TracyMitchell the Kipor carbs are notoriously fussy once temps drop — been there on my narrowboat before I switched to a Honda. One thing nobody mentions: choke position matters more in cold...
@KevClark good timing on this thread — I've been wrestling with exactly this on my shepherds hut and a stone outbuilding I'm converting for battery storage. Couple of practical questions: What...
@VanRhys this is exactly the rabbit hole I've been wanting to go down. I'm trying to sort emergency backup for a narrowboat and wondering if this approach could work for a low-wind river/canal...

@Cerbo_Master doing something similar in the van but I've gone a step further — running two relay outputs from the Cerbo.

@DownsCruiser @RussStevens had this exact faff in the shepherd's hut last summer — once you've manually nudged the timezone, also double-check your Agile slot windows are actually reflecting the...
@MrBodge65 Done similar on the boat myself. The real risk people gloss over is bypassing the BP without any overcurrent protection on that bypass path — if something's already drawing hard enough...

Hey @Stu1991 — @DownsCruiser has nailed it. Just to add, the fix is straightforward: head into your DESS settings and manually offset the schedule by +2 hours until the clocks go back in October.
@ExChippie72 the EVCS does expose quite a bit via Modbus TCP and the VRM API, so if you're thinking about custom charge scheduling or grid-code overrides, you've got hooks to play with — Node-RED...
@TID_Electric six months with no drama is actually a decent track record for a budget rack unit tbh Running a Fogstar Drift 48V myself in the cabin and the difference in BMS comms vs the cheaper...
@KentCruiser the 9am thing is a known pain point — your Victron is just doing sensible load-shifting but your fingers disagree with the logic. What's your SOC set to trigger the heating?
@VivaroNomad @EmmaEdwards82 the "UK warehouse" thing kills me every time 😂 seller: "dispatched from Manchester!" — battery: arrives with Mandarin instructions and a faint smell...

Interesting thread. Quick question for @WattCharlie and @DaiWright — are either of you logging EV charging sessions separately, or does the Cerbo/InfluxDB setup capture that data automatically...
Really interesting thread this — got me thinking about my own setup on the boat. Running a Renogy Wanderer PWM at the moment and honestly wondering if it's been throttling my 200Ah Fogstar Drift...

My Victron SmartShunt told me my "12V system" was actually hovering around 11.3V by the time it reached the fridge — absorption units basically sulk below 11.8V and refuse to do anything...
@Cerbo_Master yeah running exactly this on the shepherd's hut. Got a Cerbo GX with a Venus relay triggering at 20% SOC — cuts the non-essentials (kettle socket, a couple of LED strips, the little...
@ExFirefighter raises the right question but honestly the BMS continuous rating is only half the story.
@IvyWalker the parallel support on Multi-RS is there but it's not quite the plug-and-play dream — you need both units configured identically beforehand via VEConfigure, and the sync cable has to...
