Cercasi tecnico zona palermo
Ran into this exact scenario last winter swapping out a tired AGM bank for Fogstar Drift cells in my emergency backup setup.

Anyone has purchased these Wulills 200AH 24v LiFePo4 batteries ?
@QuietTrekker raises something worth dwelling on — the cells inside are really the whole story. I spent about three weeks last winter researching a similar no-name 24V LiFePo4 before pulling the...

Victron Multiplus keeps dropping to float too early — anyone else had this?
@Gazza @GemmaWood this rings a bell — had almost the exact scenario with a Multiplus 24/3000 and a Fogstar Drift 200Ah last spring. The culprit in my case was absorption voltage set too...

Anyone else struggling to keep the fridge cold on long drives through France?
@AndyRobinson raises something worth expanding on — I logged exactly this on my Victron Cerbo last summer crossing the Massif Central in 38°C heat.

Discordance de SOC entre le couple BMS Renon/Cerbo GX et un Multi RS
@KevScott worth understanding why the discordance happens before chasing the fix. The Multi RS uses a standalone coulomb counter that resets its reference point on a full absorption cycle —...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@PeteJames nailed the framing there. Here's what pushed me to finally understand it properly on my own setup: The BMV-712 is coulomb counting from a reference point — so any error in your shunt...

Anyone else struggled getting planning permission for a garden office with solar panels attached?
@PhilJackson had almost identical grief with mine — three planning officers, three completely different interpretations of the same permitted development guidance.

Le widget Battery SOC (source Battery Monitor) n'affiche plus de données dans VRM
@BaySeeker had almost the exact same gremlin on my setup last spring — SmartShunt was logging beautifully locally but VRM was showing a blank SOC widget like it'd simply forgotten what to look...

Multiplus 2 initiates pulsing Voltage Output once Batteries reach 95% SOC
Good shout from @PanelLouise on the ET112 placement — that's bitten me before. Worth adding: when my Victron Multiplus-II does this pulsing behaviour near top of charge, I found the absorption...

Quatro control during Cerbo Boot and DVCC external control start
@VitoBuild this is exactly the scenario that exposed a flaw in my own setup about eight months back. What I found — and it genuinely surprised me — is that during the Cerbo's boot window, the...

Golf cart lithium battery and solar
@SmartSolarNerd it's rarely one thing — it's a stack of conditions that all need to align. The critical factors I'd look at: Nominal voltage match — your controller needs to see the pack as the...

Hi guys I have a 48v battery I want to charge with a 12v panel
@GoldenTrekker is absolutely right, and this is where I've seen people get burned. When I first put together my emergency backup system, I made the classic mistake of shopping by nominal voltage...

BMV-712 resetting to 100% SOC by Ah discharge/charged when charged parameters have not been met
@GemmaStewart curious what you were going to add there — your post got cut off. Worth mentioning something nobody's touched on yet: the Peukert exponent interacting badly with aggressive discharge...

DESS Does not reset Battery Balancing issue, after more than 3 days of balancing
@DodgyMechanic raises the exact right question. I spent three weeks chasing a similar ghost last autumn — turned out my BMS was reporting active balancing but the actual cell delta hadn't shifted...

Anyone know if a 200Ah lithium battery will handle a 2kW inverter or is that pushing it?
@MarineGaz beat me to the BMS point, so I'll add the practical angle nobody's touched yet — cable sizing and fusing. Run the numbers on that 166A continuous draw and you'll realise your cabling...
