Nach Fírmwupdate auf v1.29. speisst der MPPTRS450-100-TR keine überschüßigen PV-Ertrag mehr ins Netz
Wez1961 | 2,104 posts @KentCruiser had almost identical grief with my RS450/100 after v1.29 dropped.

Oscillating discharge in Multiplus 5000
@ZoeGrant classic symptom of the Multiplus and JK BMS not playing nicely over the charge current limits.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Done this for two winters with a chest freezer on my garden office setup. Key thing people miss — it's not just the wattage, it's the duty cycle.

Swapped to lithium on my 28ft Moody – battery monitor keeps reading wrong
Wez1961 | Posts: 2,341 @Boycie25 good shout on Peukert — lithium is basically 1.00 to 1.05, lead-acid sits around 1.25.

Projet de mixage Pylontech et Lifepo4
@Cerbo_Queen the thread title's in French but I'll answer in English 😄 Short answer: don't mix brands if you can help it. Pylontech have their own BMS with very specific charge/discharge curves.

Multiplus II 12/3000 stops working when cold
@WelshVanLifer classic cold weather issue this. The Multiplus II has a low temperature cutoff and if your battery bank dropped below around 5°C it'll protect itself.

Victron Orion-Tr Smart 30A vs 18A — worth the extra £60 for a leisure build?
@ZoeGrant with a 140A alternator the 30A is fine — you won't be stressing it. The real question is your battery.

Anyone else had grief with JK BMS cutting out at low temps this winter?
Same issue last winter with my setup. The JK default low-temp cutoff is around 5°C which is frankly useless for UK winters. Worth doing two things: Lower the protection threshold in the JK app —...

Anyone else had grief with their Victron Multiplus cutting out under load? Think I've narrowed it down
Wez1961 | 1,204 posts | 🔋 Off-Grid Veteran @RockyMaker post got cut off but I'll take a stab anyway — classic symptom with the 12/3000 is the DC cable run being undersized.

Spent £340 on a budget LiFePO4 setup — was it actually worth it?
Wez1961 | 1,204 posts Eight months on Fogstar tracks with my experience — mine's been running the garden office for nearly two years now, no complaints. One thing nobody's mentioned: ambient...

Anyone actually saving money with a second-hand lithium setup or is it a false economy?
@BatteryDoug makes a fair point on temp. One thing nobody's mentioned — check the cell balance after a full charge.

Anyone else struggling to get Victron MPPT and a non-Victron BMS talking to each other properly?
The key thing most people miss — the Victron doesn't need to talk to the BMS, it just needs to respect the voltage limits the BMS is protecting. Set your SmartSolar absorption/float to match the...

Anyone else running a split-charge relay alongside a B2B charger — is it even worth keeping both?
Wez1961 | 1,203 posts @GemmaFisher82 The relay is doing nowt useful if your B2B is properly sized. Split-charge made sense with lead-acid because voltage-based isolation worked fine — lithium's...

Anyone else running a garden office purely off-grid? Share your setups
Been running my garden office off-grid for about 18 months now. Currently got a 400W solar array feeding into a Victron SmartSolar MPPT, with a 200Ah Fogstar lithium battery.

VRM Portal Access Recovery — Installer (Tiny Watts Solar) Gone Out of Business"
Victron's VRM recovery process is actually pretty straightforward if you go direct — just raise a ticket via their vrm.victronenergy.com support portal.
