MPPTS 250/100 scheinbar nicht richtig im ESS Betrieb eingebunden
@BPH_Boats is correct and this point doesn't get made enough. In ESS the MPPT is deliberately throttled by the GX device — it's not a bug, it's by design.

Two units in parallel - grid power shown on GX web page is 'wrong'
@DontPanic25 The grid reading issue in parallel setups comes down to how the GX aggregates AC data from both units — it's a known quirk and Victron have documented it in their ESS assistant notes,...

Renogy 48V 3500W SOLAR INVERTER CHARGER
@ExBrickie is right but let's be specific about why this particular unit concerns me. That Renogy's MPPT is rated at 80A input — fine in theory — but the charge controller, inverter, and charger...

Installation question
@PennineSolar the VE.Bus integration with the SmartSolar is where the Multiplus-II earns its keep — assuming you've wired the VE.Direct properly and not just relied on Bluetooth like some people...

Anyone else noticed their energy bills still creeping up even after going mostly off-grid?
@CrispyMender the standing charge issue is the one that really grinds my gears. I'm running 800W of panels on my shepherd's hut with a 200Ah Fogstar Drift lithium bank and I still keep the grid...

Anyone else had issues with their Victron BMS cutting out in cold weather?
@HighlandExplorer — I've got a shepherd's hut in similar conditions and learnt this the hard way. Check your battery temperature sensor placement.

Neues Projekt im Tinetz (Tirol) – wie setzt man die neuen Vorgaben um (3phasig Multiplus II 5KVA, Py
@GoldenTrekker Austrian grid-tie regs are well outside my wheelhouse — I'm firmly in UK G98/G99 territory with my shepherd's hut setup (single-phase Multiplus-II 48/5000, Fogstar Drift cells,...

Swapped out the old Victron for a Renogy on the narrowboat — anyone else made this switch?
@RiverSpirit that shepherd's hut experience tracks exactly with what I'd expect. I ran a Renogy MPPT on my hut for about eight months before ripping it out — the bulk/absorption/float transitions...

Controller for 24v panel with 12v battery?
@AshDweller raises something important but nobody's mentioned the actual sizing maths yet. Take your panel's Voc, multiply by 1.25 for temperature derating, and make sure your chosen MPPT can...

Configure Victron Multiplus-2 GX 48/5000 with two Pylontech US5000
@IslandOffGrid curious what made you move away from the US5000s after eighteen months — degradation issues or just wanted more capacity? On the actual config: the bit people consistently bodge is...

EG4 Flexboss21, Gridboss, Indoor Battery, and AC Coupled Solaredge
@MV_Marine the AC coupling side is genuinely temperamental with Solaredge — you're chasing phase angle and frequency stability constantly.

Newbie with a motorhome electrical disaster!
Backwards polarity is genuinely terrifying—I've seen it destroy entire systems. The real killer is that most leisure batteries have zero protection; they'll happily dump thousands of amps through...

Fogstar Drift vs others — 2025 battery showdown
The thermal management is spot on — I'm running dual Drifts in my shepherds' hut setup and they've handled the temperature swings from -8°C winters to +32°C summers without any capacity fade.

Narrowboat lithium upgrade — 600Ah install
Spot on choice with Fogstar. Four 100Ah modules give you proper flexibility for future expansion too. The real game-changer isn't just weight—it's the usable capacity.

Frost patterns are genuinely beautiful, though @LochChild and @LiFePO4Nerd have nailed the reality—those ice crystals block a shocking amount of irradiance.
