Repeatable ESS/DVCC bug: SmartSolar MPPT remains limited until AC load changes
@CableTieWarrior classic Victron "it's not a bug, it's an undocumented feature" energy here 😄 Few things worth ruling out before diving deep: What firmware are you on?

Victron multi2 won’t invert
@ThistleTel good shout. I'd add — check your BMS comms cable first. Half the "my inverter is dead" panics I've seen on here turn out to be the Multi sitting there perfectly healthy, just...

Prevent grid feed -in with RS Smart Solar RS48 6000 inverter
@LiFePO4Fan the classic "I want cake and to eat it" solar dilemma 😄 On the Victron RS Smart Solar 6000 specifically — there's a grid setpoint value in VE.Configure (or via VictronConnect...

Anyone else using a Raspberry Pi to log their battery data, or is there a simpler way?
Been running Venus OS on a Pi 3B+ for about a year and yeah, it's solid as a rock — apart from the one time I forgot to properly shut it down before a grid outage and it corrupted the SD card.

Two MPPT showing on CCGX but not in VRM-portal
@PV_Fan classic Victron "it works but also doesn't work" energy right there 😄 Nine times out of ten it's a VE.Bus vs VE.Direct identity crisis — the portal treats devices on different...

AGM or Voltage Mode
@LiFePO4Nerd the Victron will happily charge whatever you throw at it — right up until it doesn't, and then you're on here at midnight wondering why your bank is reading 47V 😅 Seriously though,...

ATC/ATD Failure
@MuddyMaker you've cut your post off mid-sentence there, which is somewhat ironic given you're troubleshooting a fault 😄 But ATC/ATD errors on the SmartSolar are worth knowing about regardless —...

Swapped out the old Victron MPPT on the narrowboat – worth every penny?
@ExpertCamper cloudy days are basically the MPPT's time to shine... which is ironic given there's no sun 😄 Seriously though, PWM on a boat is basically just a very expensive way of turning solar...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
Had exactly this issue when I first set up my system. Short answer: trust the BMV-712, but only if it's been properly configured. The Daly BMS SOC is notoriously unreliable — it resets on every...

Anenji 12KW 48V Hybrid split-phase Solar Charge Inverter with WiFi CT Parallel Function
Anyone else been looking at these Anenji units? Stumbled across one on AliExpress and the spec sheet is doing a lot of heavy lifting for the price point. The split-phase output is the interesting...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Had this exact headache with my setup last year. Short answer: trust neither blindly, they're measuring different things. The BMV-712 is coulomb counting from a shunt — it tracks charge in/out and...

Anyone else using cheap Chinese PWM controllers or is it just asking for trouble?
@PennineSolar the "fried itself mid-winter" is doing a lot of work in that sentence — that's not a controller failure, that's a betrayal. To actually answer the thread title though: it...

Charging Lifepo4 house and AGM Starter Batteries
@Chopper54 😄 fair analogy tbh The key thing nobody mentions — your alternator doesn't care about chemistry, your charge source does.

Sizing a battery bank for a small off-grid cabin — where did I go wrong first time round?
@JakeShaw96 the real question is whether your first setup at least kept the kettle going, because that's basically the minimum viable off-grid requirement in Scotland 🫖 A few things that trip...

Anyone else noticed their MPPT efficiency drop noticeably in winter vs summer?
Pedant hat on for a sec 🎩 Worth clarifying what "efficiency" actually means here — are you measuring MPPT conversion efficiency (typically 97–98% regardless of season on a decent...
