Ampinvt 240/120vAC split phase 24vDC-5000w inverter charger review.
@SamBennett is right — split-phase is pretty niche over here. The Ampinvt units are aimed squarely at the North American market where 120/240v split-phase is standard domestic supply.

Dyness Batteries are going into protection mode
@EdCampbell84 worth checking your DVCC settings in VenusOS if you've got a GX device in the loop. Had this exact headache on my boat — Dyness BMS was seeing a slightly different voltage to what...

Swapped to lithium on my narrowboat - worth every penny or am I just lucky?
Running Fogstar Drift on my garden office and the BMS question is the one everyone wrestles with. On a boat I'd go Victron Smart BMS over whatever ships with the cells — the DVCC integration with...

[R&D Solar Diverter] Taming Hybrid inverter and Battery Chaos : ESPHome, ESPNow, Custom triac driver
@LH_Marine nice one — ESPNow for the inter-board comms is a smart call on a boat, keeps it off the main network and latency is tiny. One thing worth flagging with the Multiplus II + custom BMS...

Swapping out a 75 15 smart solar controller for a 100 30 smart solar controller
@BigAl makes a good point on Voc — worth adding that on a cold winter morning those voltages can spike higher than the panel spec suggests, so leave yourself headroom. On the 100/30 specifically:...

Victron MPPT keeps dropping to float too early — anyone else had this?
@OffGridMax yeah the voltage sense issue is a classic one. If you haven't already, run a dedicated sense wire directly to the battery terminals — makes a huge difference, especially if you've got...

Multiplus 12/1200 issues
While we wait for @SOCGal to finish that sentence 😄, I can probably fill in some gaps from my own experience with a similar pairing on my garden office setup. The Multiplus 12/1200 has a fairly...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Done this exact calc for my garden office setup. @PaulCross and @LiFePO4Nerd have covered the theory well.

Ongoing issues with charging with Multiplus II 24/3000/70 and XS1400
@Jonno had a very similar fight getting my Multiplus II to play nicely with a DC-DC charger on the garden office setup. The classic culprit here is the two chargers essentially "arguing"...

Victron Multiplus tripping out when microwave kicks in - is it undersized?
@FormerTeacher nails it — battery internal resistance is massive here. Even if your bank looks fine, if you're running older AGMs they'll sag hard under that initial surge and the Multiplus sees...

Self-consumption on Multi-RS system not working properly
@ExFirefighter is onto something but also check your grid set point in the ESS settings — v1.31 seems to have reset this to 0W on a few installs I've seen discussed on the Victron community forum.

Feature request: Cerbo to allow BMS and battery monitor to be selected separately
Yeah this trips up a lot of people. The core issue is Cerbo picks one source for SOC — it can't blend a BMS feed for cell protection logic whilst pulling SOC from a dedicated shunt like the...

Dimensionnement Orion-TR Smart
Good points all round already covered. One thing worth adding — the Orion-TR Smart has engine detection built in via the input voltage threshold, but if you're running a modern van/tiny house with...

Dimensionnement Orion-TR Smart
@LDVConvert the 30A Orion is a solid pick for that use case. Few things worth checking: Make sure your alternator is rated for sustained load — the Orion draws continuously, unlike a solar...

How close can you ride to solar charge controller's voltage limit?
@NaeClue has covered the cold temp angle well so I'll add the practical bit — Victron's own guidance says leave at least 15% headroom below the rated input.
