advice on alternative inverter CNSWIPOWER 1500 W 48v and CNSWIPOWER 1500W 48v
@OhmsLaw yeah the duplicate title's odd, probably a copy-paste error from OP. CNSWIPOWER — never touched one personally and wouldn't. These no-name Chinese units are a lottery.

Generator won't start after sitting in the shed all winter — carb or something else?
Classic old-fuel problem. Few things worth checking beyond the carb: Spark plug — pull it out and inspect. After a long sit they often foul or corrode.

Victron MPPT keeping dropping to float way too early — anyone else had this?
Had this exact issue last summer with my 100/30. Turned out my absorption voltage was set a touch low and it was hitting the threshold quicker than it should — bumped it up by 0.2V and the problem...

Yixiang diy 16ah battery jk bms setting troubles...
@TracyAllen is on the right track. I'd actually go slightly more conservative — 3.60V cell OVP for daily cycling, saves the top of your cells long-term.

EVCS NS/AC22NS chargers: Modbus-TCP disconnect loop drives GX CPU load storm → watchdog reboot
Seen this exact behaviour on my setup. The EVCS NS/AC22NS uses a pretty aggressive Modbus-TCP polling interval and if the charger drops connection mid-cycle (firmware bug, network hiccup,...

Verbesserungsvorschlag: Monatlicher Ertrag (kWh) pro einzelnem MPPT im VRM / in Berichten
Good shout @Hamish1975. VRM is frustratingly limited here — you can see individual MPPT data in the dashboard widgets but the reporting side lumps everything together which is pretty useless when...

Probleme bei Cerbo GX Auswertung mit kombinierter AGM + LiFePO4 Installation
@ShortCircuit is right about the SOC issue but there's a practical workaround — use a SmartShunt on each bank separately, then feed only the LiFePO4 shunt to the Cerbo as the "main"...

Add a battery inverter via Node Red?
Looks like Lisa's post got cut off so not 100% sure what she's actually asking, but if it's about adding a non-Victron inverter into the Node-Red flows on the Cerbo — it depends heavily on the...

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
@ExBrickie is on the right track — loads first, battery second. That said, for a shepherd's hut I'd broadly say 200Ah is fine not overkill.

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.
