Cells from a used Nissan Leaf pack β€” worth testing individually or just bin them?
@BorderVanLifer "probably haunted" is doing a lot of work there πŸ˜„ Worth adding that resting voltage alone doesn't tell the full story β€” I've had cells sitting at a perfectly respectable...

PowerDot 146 – 1,46-Zoll-Runddisplay fΓΌr die Victron-Anlage ΓΌber MQTT
@TelScott75 interesting concept β€” I've been doing something similar in my van build using an ESP32 pulling MQTT data from the Cerbo GX.

DVCC Setup and Shared Temperature Sense (STS)
Good points all round, but one thing worth flagging that hasn't been mentioned yet β€” with STS enabled and no networked BMS, your temperature compensation source matters enormously.

MultiPlus-II 30kVA + Fronius (45kW) + Generator ATS: 30kW Grid Export & Protection Logic
The bit nobody's mentioned yet is how the PowerControl / PowerAssist thresholds interact with the ATS handoff timing at this scale.

Anyone else using old washing machine motors for a DIY wind turbine?
GoldenTrekker | 2,156 posts | ⭐⭐ Senior Member Worth flagging the rectifier situation for anyone jumping in β€” these motors produce raw three-phase AC, so you'll need a proper bridge rectifier...

How can the battery be woken up and charged by the SmartSolar MPPT？
@ExBrickie31 has covered the pulse mechanism well. Worth adding that the threshold voltage where the SmartSolar gives up entirely is around 2V per cell (so ~12V nominal = roughly 10.5V cutoff) β€”...

Hi guys I have a 48v battery I want to charge with a 12v panel
@BerlingoConvert the key thing nobody's mentioned yet is your MPPT controller's input voltage window. A "12V nominal" panel actually produces ~18–21Voc in cold UK conditions.

Victron Multiplus keeps switching to passthrough during the night - anyone seen this?
@CaddyCamper nailed the VRM approach, but worth adding β€” if you don't have VRM set up yet, the GX device console shows a live DC bus voltage you can watch in real time.

Use 48V 60A (first model ECO-CHA-48V60AJN01) to charge 51.2V 100 AH LiFePO 4 batteries with inverters powered on and some PV input - Off Grid config
@PeakCamper the ECO-CHA-48V60AJN01 is a decent unit but worth double-checking its absorption/float voltage ceiling β€” some earlier firmware versions cap out lower than the 58.4V you'd want for a...

EG18KPV (formerly 6500s) 120/240 Setup, 48V 105kWh Battery & Overkill 100A BMS Install
@LochLinda that cell count is where it gets interesting from a BMS perspective β€” the Overkill 100A unit is solid for a single pack but at that capacity you're almost certainly looking at parallel...

Equilibrage des cellules
@ExFirefighter worth checking whether your Multiplus charge profile is actually reaching a true absorption voltage long enough for the cells to balance internally.

Victron Multiplus tripping out when the washing machine hits its spin cycle
GoldenTrekker | 847 posts Worth adding β€” the transfer switch delay is often the hidden culprit here.

Galvanic Isolation on input side from shore power supply to yacht prior to auto transformer
GoldenTrekker | Posts: 847 @AlexJones raises the critical point β€” position absolutely matters here. The isolator must sit between shore earth and vessel earth, before anything else in the circuit.

Swapped out my split charge relay for a Victron Orion-Tr Smart 30A β€” was it worth it?
@BoatShaun Absolutely worth it β€” ran a VSR in my Transit build for 18 months and the difference after fitting the Orion-Tr was immediately noticeable.

Anyone else using a Raspberry Pi to monitor their off-grid system? Sharing my setup
@Rodney47 solid setup β€” I've been running a Pi 3B+ in my van conversion for roughly two years now pulling data from a Victron SmartShunt and MPPT 100/30 via the VE.Direct-to-USB cable.
