Multi 12 80 2000 swaps neutral and line

Victron Phoenix 12 80 2000 swaps line and neutral when inverting.

Marine installation, has been working for many years with occasional shorepower RCD trip.

The outlet sockets on the boat are switched on by a small MCB on the board. The MCB is solely and directly supplied from the Multi‘s output Line wire, N combines to all other Ns.

The Multis input is correctly wired to shorepower.

With the socket MCB switched off, all other MCBs lines are life when shorepower is connected.

As soon as the socket MCB is switched on the external shorepower RCD trips.

If shore power is internally switched off at double isolator. I can switch the socket MCB on and consumers supplied by these socket outlets will work.

However, I can now no longer detect a life signal at the supply line point of the outlet socket MCB but instead on the combined neutral point on the board!

This is of course the same with every socket, a life signal on all neutrals.

What is happening here?

Starlink not booting on 12/250 Phoenix Inverter

I’m not having much luck getting the Victron Phoenix 12/250 to power my Starlink internet, and am hoping that someone can help please. When on the inverter, Starlink will reboot about 30s after power up. If I have a light bulb also connected, the bulb will briefly flicker at that stage too.

The Starlink dish (gen 1, round with black cables) normally consumes approx 80W (PF 93%). However during startup it can draw more than that. (174W for a second according to my own measurements.) The rating of the inverter is 400W peak, so would seem to be well within spec.

The inverter has been tested as being ok by the local Victron service agent. However a replacement is being made available. I’m not particularly confident that the replacement will fare any better (unless it has different firmware). Is there any diagnostic information available from the inverter (other than the LEDs)? Any other suggestions for my testing? Has anyone got a gen1 Starlink dish working off a Phoenix Inverter?


Background info:

  • I calculated that my 12 VDC wiring + connections have a resistance of less than 7.8 milli ohms. (This is based on the voltage drop measured when the inverter was driving a 60W incandescent light bulb). The cables are short (<30cm) and there is no fuse (anymore).
  • The battery is in a Ford Territory, and starts the engine ok. I’ve tried with and without the engine running. So I’m reasonably confident that it's not a DC issue.
  • Snow melt mode on the dish is off. Eco mode off on inverter
  • I’m not a power electronics specialist, but I’ve got a degree in electrical engineering so hopefully I can understand a bit of technical talk.

How do I see Phoenix 12/1200 on/off controls on the VRM Dashboard?

I have enabled inverter/charger control in VRM settings page, but when I click on the controls icon in the upper right, all I see is a toggle for "Switches: Relay 2". I can control on/off state through the remote console, but I'd like it on the Dashboard. I have latest firmware in everything as of 2022 Nov 24

phoenix 24/500 wrong idle power 100VA


my 24/500 phoenix shows 100VA idle AC consumption, but nothing is connected to AC.

He is connected to a CERBO and the DC loads are for no reason at about 90W when connected via ve.direct. When the ve.direct is disconnected DC Loads are close to 0W in this situation.

There is also a Multiplus 24/3000 connected to the cerbo, so i can't see the phoenix at the dashboard, but in the menu, and there are the about 100VA AC Load.

What's wrong with the phoenix?

Parallel use of Blue Smart IP22, MPPT 100 /20 and DC2DC 12|12|18 on the same bus with load?

I am trying to properly connect devices within the same container. Hopefully I have given enough information to answer the question.

I the following:

  • Blue Smart IP22 12/30
  • Smart Solar MPPT 100 /20
  • DC2DC 12|12|18
  • Phoenix 12 | 800

The goal is to move this box between different cars and a camper. The only time there would be a combination of power inputs is during driving and Camping in the camper.

  • Camper = Shore + Solar
  • Car = DC2DC + Solar
  • May happen, but unlikely - I can't think of a time where all three are running simultaneous but if they are all in the same box there is that potential, so I want to plan for it.

DC2DC connection:

Alternator connection to DC2DC is 2AWG high strand pure copper welding cable the car with the longest wiring connection to the rear is 18 feet (36 for both + and -) It uses a 50a Anderson connector which will attach to a short set of cables (6 awg) 3 foot (6 foot both + and -) into the container through another set of Anderson connections. (Less than 1' on the inside of the container) to the DC2DC charger.

MPPT connection:

Total length of wires (10awg) including all the 2S 2P is 30 feet. up and into the PV input on the MPPT.

Inverter Connection:

The inverter will be able to pull power from that same main bus connection (using 8 awg cable between the main bus and inverter input). While all three devices potentially charge. However, the inverter output is separate from any of the DC bus or connections and will run through a GFCI outlet to two corresponding 15-amp outlets (max output for both at the same time controlled with a small Bussmann breaker)

Main bus + connection:

According to the BMS specs on the battery It can charge or discharge at 200A. I do not plan for any discharge or charge of more than 100a for any length of time. This is attached to a 200ah lithium (LifePO4) home build battery I picked up from a friend who built it. (It has ~600 cycles on it so it’s tested well and still basically new)

The battery will be within 5 feet of the box (cables that connect it will be 4awg so max distance from battery to the main bus connection is 20 feet including the short runs to any loads.)

Between the main bus and the battery is a 100amp ANL fuse. (Located inside the container)

All lines off the main bus connecting the MPPT, DC2DC, and IP22 are 10 awg high stranded pure copper.

Load Connection:

Max DC load draw will be 45 amps based on how I have it fused from a blue sea 100-amp 6 circuit blade and no single fuse is over 15 amps. This will get its power from the main power bus bar

Assuming all wires and fuses are properly sized for the power:


Can I allow MPPT battery output, DC2DC output and Shore IP22 to send output to the same bus without harming the devices or the battery? The bus is a 250a bus and would have all 4 devices connected. (This includes the inverter's input / draw connection and a connection to the BlueSea so DC power could also draw a load from the main bus)

(If my wire sizing or fuse sizing is off, you can comment on that, but my main question is related to the bus and having all devices connected to the same one internally)

Sump pump backup using Victron inverter and charger?

Hi, I've read all the relevant posts on the forum including this one but it's a slightly different use case.

I need a battery backup solution for my 110v sump pump, which draws an average of 700W (startup is usually around 1000W briefly). I can't do a 12v backup pump because of the small size of the sump pit (it's in my driveway).

It seems like this product on Amazon does what I need, which is basically an inverter/charger that automatically switches over to the battery when the power goes out. However, I would much rather spend the money on Victron because of the quality, even if it costs a couple hundred more.

So, that's led me down the path of getting a Victron Blue Smart battery charger and a Phoenix 12 1200 inverter instead. It sounds like it can do the same job, with the exception of automatically switching over when the power's out. With just those two parts, the sump pump would always be powered off the battery, right?

If I wanted it to switch over to the inverter/battery ONLY when the power's out, it seems like I would need a Multiplus Compact, but that also appears to be overkill for my scenario.

Any thoughts? Thanks!

Phoenix VE 12/1200 Remote not working

I have just installed a victron VE 12/1200 inverter and the remote connection doesn't appear to be working.

For example. If the inverter is On or ECO, the inverter remains on regardless of the remote switch position.

Even if I remove the green connector, the inverter remains ON.

If I have the main switch in the OFF position the inverter remains off regardless of the remote switch position.

Can you advise the correct switch position and how the remote wire should work?

Can't really see here as flash from phone make it seem like green LED is off, but it is on and both configurations still provide power to the microwave.

Victron Phoenix 500VA 24-Volt - voltage unsteady/shutdown

Is it normal to see voltage swings on a 250W load for the Victron 24V 500VA inverter? its been swinging from 113v -125v and shuts off the inverter every 20 seconds or so. On the same load, my multiplus is holding 120V exactly.

Battery is at ~26V with lots of AH left (the multiplus can run full blast).

It is on the latest firmware and is connected to a Cerbo GX, 30A fuse, 8Gauge pure copper wire, connections are secure.

Any help is appreciated , otherwise its going back, its brand new from Victron dealer.

Victron Phoenix 24/500 230V 400W VE.Direct - below specs or broken?

I have bought a Victron Phoenix 24/500 and during testing stage, I found that its performance is lower than specified. So far I have observed the following:

1) Idle load 10-11W > 6.5W from specs.

2) Measured efficiency is peaking at 87% using loads with power factor of 0.85-0.9, instead of 90% as specified.

3) Inverter entered what appears to be overload protection when connected a hairdryer with a measured power of 335W (<400 specified) and a power factor of 0.9, however it was able to sustain a 400W load composed of 100W electronics and a 300W lamp, having a power factor that was again ~0.9.

4) Not able to power the starting phase of a refrigerator compressor which has a continuous power requirements of 60 to 80W and a peak during startup of ~500-700W.

I understand that first 2 points could have their root in incorrect datasheets, case in which a correct one would be appreciated. Honestly, if a producer writes 6.5W idle power and I measure 10, I am wondering what else is not true in the datasheet. However points 3 & 4 look to be some issues, specially 3 . Any advice? or there are some overly aggressive protections built in?

Inverter Product line

I am shopping for a 1600VA inverter. Can somebody briefly explain the differences between the plastic cased (what i assume is a newer line) and the metal case "compact" line.

I already have a charger, but I am open to the idea of maybe combining them. But both the Multiplus and the Phoenix seem to have this plastic/metal variants.

There also appears to the "smart" line (not that big a fan of bluetooth, for this mobile home application). In total there appear to be 4 different 1600VA inverters. Thanks.
