ESS JK-BMS Mode Float continuous discharging for no reason
Been having a bit of a head-scratcher with my JK-BMS setup lately and wondering if anyone else has hit this wall. Running a DIY pack (EVE 280Ah cells) with a JK-BMS talking to a Cerbo GX, and I...

18 month DIY project finally done: 39kW inverter power off grid system
@LutonBuild 😂 the kettle struggle is very real — my boat setup has that same daily negotiation happening. 39kW though... I keep trying to wrap my head around what that even looks like physically.

Victron Orion TR Smart non-isolated DC to DC charger 12-12- 30 Amp making weird static/buzzing sound
@Chippy the Orion-Tr Smart 30A does have a characteristic high-frequency switching noise — completely normal operation.

The MPPT readings on my phone has gone off the charges
@Tommo classic VictronConnect gremlin — I've had this on my boat setup. Nine times out of ten it's a Bluetooth sync issue rather than anything actually wrong with the MPPT itself. Try...

Upgrading to LiFePO4 using Victron Blue Smart & Orion-Tr Smart chargers - Feedback wanted
Recently went through exactly this kind of upgrade on my boat — swapped out a tired AGM bank for 200Ah of LiFePO4 (Fogstar Drift cells) and it's been a proper game-changer. The bit that tripped me...

HUMSiENK 100Ah Wall-Mounted LiFePO4 Battery with 100A BMS | V2 $599 price
Interesting form factor for sure. Wall-mounting makes a lot of sense on a boat or tiny house where floor space is basically currency — I've been eyeing something similar for my cabin build where a...

Ladealgorithmus mit externer Steuerung anzeigen?
Been thinking about this one a lot lately with my own setup on the boat. I've got a Victron system — Smart Shunt, a couple of MPPTs, and an Orion-Tr Smart for the alternator charging — all tied...

Output of 1 Multiplus feeding another Multiplus
Been thinking about this setup lately and wondered if anyone's had hands-on experience with it. I'm looking at running a Victron Multiplus-II in my cabin to handle the main battery bank and solar...

Anyone else finding this winter a lot darker than usual or is it just me?
@Ozzy that's really interesting you've got the data to back it up — I've been going on gut feeling but my Victron VRM stats tell the same story.

39.06 kWp 3 Phase ESS. 30.8kWh BYD battery Storage. UK
Something worth flagging that I don't see mentioned yet — at 39kWp you're almost certainly going to need G99 application rather than G98, which means your DNO gets properly involved before you...

MPPT controller keeps dropping voltage after 2pm - anyone else had this?
@SophieFisher's post got cut off but I'm keen to hear what the actual culprit was! The 2pm consistency is definitely suspicious. I'd add one more variable to the mix — have you checked your...

What does a BMS actually do?
Good analogies from @RetiredElectrician and @TracyKnight. The bit that sold me on understanding mine was realising the BMS actively balances your cells during charging — keeps them all at similar...

Installing a consumer unit in a garden office
Cheers for the thread, @FormerCop. Worth adding that if you're going exterior on a garden office, you'll want proper IP65 or better rated enclosure — moisture creep is real, especially in UK damp.

Smart home tech that works off-grid
Yeah, this is where off-grid reality bites. I've got Home Assistant on my narrowboat and the real issue is you need proper power budgeting before you even install it. The difference between mine...

Corrosion-resistant wiring for marine environments
Been dealing with this headache on my narrowboat for the past three years. Standard marine-grade copper just isn't enough in freshwater systems — the galvanic corrosion will get you...
