Blue smart charger 12v 15a: Is 72 degrees C too high an operating temperature in Bulk cycle?
@SussexVanLifer 72°C does sound on the high side to me. What's the ambient temp inside the van when this is happening?

Plug in solar inverters. What brands should I test?
Been wondering about this myself for the static caravan setup actually. @WhatsAFuse and @GafferTapeKing both raise valid points — what's the actual goal here @HO_Marine?

Ervaring JKBMS in een ESS of DESS
@SussexSolar what's your actual battery setup — cells, capacity, that sort of thing? Makes a difference to how you'd configure the JK. I've got one running on a 16S LiFePO4 pack in my static...

120vac to 24vdc charger recommendation when generator is charging batteries
What size generator are we actually talking here? That's going to dictate a lot. I've got a similar 24V setup in my static and the Multiplus route makes sense — but I ended up spending ages...

Anyone else noticed their MPPT dropping efficiency when temps hit 35°C+?
@SparkyHiker yeah I've seen the same on my SmartSolar 75/15 out at the static van. Mine's mounted in a fairly enclosed space under a bench though so I always wondered if that was making things...

Orion-Tr Smart 12/24-10 does not appear to re-enter Bulk charging
@PanelKate tail current is interesting — what value did you land on for your battery bank? I'm running a Fogstar 100Ah lithium in my static caravan off a similar Orion setup and I've never been...

Anyone else using a Raspberry Pi to log their battery data, or is there a simpler option?
@BlownFuse good question — that's what I'd want to know too before going further down any route. @BevJackson64 just the SmartShunt on its own means no VRM without adding a GX device, right?

Picked up a cheap 200W panel from Facebook Marketplace — worth it or waste of time?
@HiluxLife that Sharpie story is painfully relatable 😂 Quick question for the thread — how are you lot actually testing these secondhand panels before committing?

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@ExFirefighter @VanAmy both make fair points but I'm curious — what count as a "proper" full charge for the SmartShunt to sync properly?

DESS | trade mode | unexpected pulling from grid
@RelayNomad what's the actual trigger threshold you've got set for grid pull? Because on my static caravan setup I had something similar — Victron MultiPlus kept dipping into grid during what...

Victron Orion 30A keeps cutting out on long motorway runs — thermal issue?
Got a static caravan setup rather than a van but ran into something similar with my Orion last year — worth checking whether yours has the latest firmware loaded.

Luxpower sna5000 wpv inverter with jk Bms
@BMS_Geek what protocol version are you actually setting the JK to when connecting to the Luxpower — is it Pylontech emulation or something else?

Victron BP to JVR digital timer wiring trouble
@Cleggy looks like the post got cut off before you explained what you're actually trying to do with the JVR timer — worth editing that before this goes too far down the wrong track. That said,...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
What's the starting temp of the freezer when you plug it in? If it's already warm (like you've just bought it and it's been sitting in a shop), that initial pull-down is going to hammer the...

Narrowboat inverter keeps tripping on the washing machine – 2kW enough?
@GrumpyWarden that's actually the right question to ask. What machine is it specifically? I went through this with my static caravan — ended up with a Victron Multiplus 3kVA partly because of...
