Phoenix 12/1200: How to connect the output neutral to ground

I need to ground the output from my Phoenix 12/1200. I see the diagram in the manual appendix but it's a bit too abstract for me. Has anyone seen better documentation or a video that explains this better? Thanks!

Is there a Phoenix 12 1200 model with no bluetooth or VE Direct?

I'm just looking to confirm that there was a Phoenix 12 1200 model made that had neither VE Direct port or built in bluetooth? I can't easily find a definite answer to this online. Previous owner of my boat install the inverter, hence I don't know exact age and there doesn't seem to be any more specific part / serial number on it.

Phoenix inverter 24 500 issue with dimmer lights

Phoenix inverter 24 / 500 is giving me problems with the dimmer lights

The lights flickers when on inverter mode if I dimm them a bit but if I leave them on max output they work fine, if I move the lights to the grid they work perfectly either dimmed or at max output.

Any help on this?

inverter mppt Master and salve config

Hello ,

I am new user of victron and I know that we can connect 2 inverter together to the same AC .

My question is bit more complicated than that .


The Australians law said we can connect the mppt inverter to the grid it's forbidden except if we ask the fournissor and let an electricians to do it .I don't want that .

My ideas is simple to respect the law and be connected to the grid ,I got an ideas I saw some power supply 240v to 400V 50A .

One mppt inverter will have a power supply 240V to 400V 50A connected to the solar panel inputs off course no solar panels will be connected on this inverter and the inverter will not see the difference .

Second mppt inverter will be connected to the solar panels 5KW .

both will be connected in parrallel to have 240V in the house .

1) if my house use 2KW ,I want to get this power from the second MPPT inverter and turn on the first MPPT inverter to not use any electricy from the grid .

2)in case that the solar panel produce 5KW and my house is using 8k the first MPPT can come to help and produce 3k on the top of that ?

Please tell me which MPPT inverter can do .
Thank you

Phoenix inverter 24/3000 230v overload LED flashing with no load then shuts down

Hi, thanks for letting me join your community. Apologies that my first post is a problem question, but hopefully as I learn more about these devices I will be able to contribute something as well!

I recently purchased a used Phoenix 24/3000 inverter with the following identification information:





MCU Firmware 1812144

PCB 010021

PIN 24/3000



It worked perfectly for the first two weeks, but now it has developed a fault where it will not power-up. I have not overloaded it (max load has been around 1000w and fan was heard cycling normally).

The symptoms are that immediately after switching on (even with output terminals disconnected) it does one of the following:

  1. Produces correct output voltage for about 4-8 seconds with green LED on and overload LED flashing, then shuts down with only the ‘Overload’ LED is lit solid.
  2. Does not power up at all and only the ‘Overload’ LED is lit solid.

I’ve checked all the obvious things like battery connections and voltage at busbars, tightness of all nuts/bolts in the DC bus, re-seated all internal connections between circuit boards, looked for any obvious internal damage or signs of overheated components on the PCBs. There is no evidence of thermal stress on the PCBs or transformers, no corrosion or any other damage.

There are no unusual noises, just the usual quiet hum of the transformers until it shuts down.

I was hoping to get some useful diagnostic information via the RS485 port and Victron software as I have a generic RS485 to USB converter, but I cannot find the pinout for the connector on the control PCB, nor the baud rate used by this device.

Thanks in advance for any help.

Phoenix Inverter Smart 12/1600 Eco Mode Overload


I'm experiencing an issue with a new install of a Phoenix Inverter Smart 12/1600. The device works absolutely fine when in normal mode, but when I switch to Eco mode, the red Overload light comes on and after a short period it disables. I can restart it, but same issue.

On my AC side I have the output going into a small garage type consumer unit, and when this units main fuse it switched off - guaranteeing no load at all - the device still behaves the same, so where is the overload coming from?

Anyone else had an issue with the Eco mode?

VE.Bus BMS with non VE.Bus Phoenix Multiplus

I have a VE.Bus BMS and a very old Phoenix Multiplus inverter charger that doesn't have VE.Bus.

My concern is:

- how can the VE.Bus turn off the charger to protect the batteries against overvoltage when charging?

- Can I put a battery-protect in-between the phoenix and the batteries?

- Will the charger be damaged if the BMS disconnects the batteries via the battery-protect mid-charge?

- Are there any other options?

How much airflow per watt of inverter load?

As much as I'd love to mount my Phoenix 12/1200 in free air, it just has to be in a compartment. I can add all the fans I like, though. How much is enough?

The Phoenix datasheet quotes its "max" efficiency at 92%, I'm going to be a little pessimistic and figure 85%. If 15% of 1200 watts is turning into heat, that's 180 watts I need to move.

Hey, that's pretty similar to the TDP of an average PC, which is adequately cooled by a pair of 25cfm case fans, so I figure something like 50cfm ought to do it. I'm looking at a fan rated at 62cfm, maybe I only need one of those.

There MUST be a more rigorous way to figure this, but all the formulas I find require you to know things I don't know, like the thermal resistance of my heatsink. (Okay, that's internal to the Phoenix, and anyway, it has its own fans so I'm lost at how to even begin.) Does my cocktail-napkin math sound sane, at least?

Also, since I don't have the unit in-hand yet, does anyone happen to know which side of the Phoenix is its intake and which side is the exhaust? The manual says not to mount it with the fan on top, but I can't tell from the photos which side that even is.

Thanks in advance!

Minimum load power to start

Hello everyone,

I would like to know what is the minimum Watts the load needs to be in order to allow the inverter to work.
I'm asking this because a client of mine needs a 24V-1600 Phoenix Smart to power a 9W LED light 24/7 + other loads only a few times a day.
Actually the question arose due to another site where a 7W LED light doesn't turn on if no other load is connected as well.

Output of Phoenix Smart Inverter feeds AC input of Multiplus II (Off-Grid). Possible?

I currently have a Phoenix Smart inverter 48/3000 and also just got a Multiplus II 48/5000 delivered.

The interesting question arose if I can use the smart inverter as the AC input of the Multi and activate Power Assist in the assistant. Obviously I have to turn of the charger in the Multi.
Both inverters are connected to the same battery which is charged from MPPTs only. There is no grid connection at all and no AC coupled solar.

The Multi can handle all sort of AC inputs from what I understand, so would such piggy-back solution work? It should synchronise to the Smart inverter's output, right?

Victron phoenix inverter fan

Hi. I am using a 375w phoenix inverter and plan on plugging in a 250w heater. It works fine but as the unit is under load the fans come on and stay on as long as the heater I have plugged in is running. Is it going to be bad for the fan if I run the heater overnight so the fan will be run constantly for several hours at a time. With how fast and loud the fan is I feel that running it so hard for so long over a period of time will just kill it. Any advice welcome.

It is connected to 12V/200Ah Lithium battery and when switched on, all 3 lights on the panel comes up for couple of seconds and then goes off, without any humming sound (that it used to have when it was working ok). Lithium battery is fully charged. I have checked the circuit breaker ok (200amp heavy duty MP brand and to make sure replaced with another brand new one).

What more troubleshooting can I do?

Minimum specification for Phoenix 24/5000 inverter.

Is the minimum 400Ah 24v pack recommended in the manual for the Phoenix 24/5000 inverter based on lead acid battery chemistry?

Would I be correct in assuming that as LiFePo4 chemistry has more than double the usable energy of lead, that a 200Ah 24v LiFePo4 would suffice (with a BMS of 1C continuous / 3C for 1s burst) ?

So far so good and no problem at all. BUT since Earth, Neutral and battery Negative are connected together anyways, I assume there's no issues having two separate inverters sharing their Neutral connections.

Connecting to old phoenix multiplus 12 1600 70 through mk2


I want to set up two old phoenix multiplus 12 1600 70 inverters to operate in parallel.

I am running VEConfig/VE.Bus System Configurator/VE.Bus Quick Configure on a Win 7 machine. The MK2.2b is connects with a "USB to Com Port RS232 LogiLink Adapter" to the Win 7 machine and with a ethernet cable (cat5) to the multiplus.

The inverter switches off (green light turns off and the humming sound stops) as soon as the connection is made from the inverter to the MK2. ´The victron software sees the MK2, but can't find the inverter.

What am I doing wrong?

Do I need a special RS232 cable?

Wanneer ik de walstroom erop zet is er weer 220V

kan het zijn dat ik te weinig accu vermogen heb staan?
