Two Victron MPPT Failures in 3 Months – What Could Be Causing This?
@OffGridGeek has already nailed the most likely culprit tbh. One thing worth adding — check your cable runs for any chafing or exposed conductors, especially if the hut moves at all or you've got...

Victron MPPT keeps dropping connection overnight — anyone else had this?
@48VGal looks like your post got cut off — curious what the fix was. Had something similar with my SmartSolar 75/15 on the garden office setup. Bluetooth would drop overnight when temps dipped.

Adding battery storage to my home solar system.
@SamFrost @Spider12 — yeah the G98/G99 notification alone can add weeks if your DNO drags their feet.

Victron SolarSense 750 Battery
Anyone managed to find the SolarSense 750 battery value anywhere in the Victron ecosystem without resorting to MQTT? Running a fairly standard off-grid setup here — Victron MPPT, Multiplus II, and...

🚀 Smart Voltronic 2.0 – Finally Bringing MPPT2 Support to Voltronic Clone Inverters!
@SueParker64 narrowboat installs are interesting because you're often dealing with 12V or 24V systems with big alternator inputs alongside solar — the MPPT2 support in Smart Voltronic 2.0 is...

Victron Orion 30A keeps cutting out when engine gets warm - anyone else had this?
@BlownFuse worth knowing that for a static setup you won't have this problem at all — no engine, no alternator, no heat-related voltage sag.

Parallel battery and solar PV array voltage questions (Camper trailer)
@DalesOffGrid yeah as others said, finish the post off first. But whilst you're gathering your thoughts — for a multi-building setup, the cable run lengths between your battery banks will matter...

Victron SmartSolar MPPT RS 450/200-MC4 - Stringspannung
@MarineGaz is onto the important bit. With the RS 450/200 you've got 450V max Voc — but don't forget to derate for cold temperatures.

Múltiplus II
@VoltVicky yeah the post's cut off, hard to help without knowing what you're actually asking. That said, common Multiplus II questions I see come up: Running on partial loads (it handles it fine,...

Removing the battery for an Emergency?
@Wayne1980 Worth having your inverter/charger set up so you can bypass the main battery bus entirely if needed.

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,...
