Phoenix not displaying correct info on console to Venus GX

Good day

I have a Venux GX connected to a Phoenix 24V 250VA inverter (and also a BlueSolar 150/35).

On the remote console and also in VRM portal, the inverter is indicating as "off" and not showing any AC load consumption. But in the device list it is indicating as "on" and "inverting" although even there it indicates load as "0W" (whereas in fact the load is around 35W).

Guidance will be appreciated.

Float voltage is too high

I have a Victron multi-plus 12-2500-120 inverter on my boat. When moored for the winter, I am connected to shore power (120v) and run a small heater and dehumidifier on board. I set the inverter to "charge only" so that if shore power is lost, the heater doesn't drain down the batteries. The float voltage never drops below 13.9 volts which is too high for good battery life. If I shut off the heater and dehumidifier, then the float voltage eventually drops down to 13.2 volts, which is where I like it. How can I get the float voltage down to 13.2 when it is somehow sensing that there are loads on the system?

Phoenix Multi control and a MultiPlus 3000

I have just bought a Phoenix Multi Control on eBay and have connected it to my MultiPlus 12v 3000 but it doesn't work. I have disconnected the DC power to the MultiPlus and tried again. I have also changed the cable but still not working.

I am trying to work out if the problem is with the MultiPlus or the remote. All other functions on the Multi are working fine. I have not had it connected to a remote before.

There is a soft 'clunk' sound from the MultiPlus when I switch it on via the remote, but it doesn't actually turn the inverter on properly. There is a similar sound when it is turned off. Is there a digital/analouge difference in technology with the Phoenix Multi control that's not compatible with the MultiPlus?

Grateful for any advice.

Wrong idle AC current via from Phoenix Inverter 12/800

I operate my Phoenix Inverter 12/800 together with a Blue Smart 100/20 and 2 parallel 100 Ah batteries via with the open source solution "solaranzeige" on the Raspberry PI 3b+

I have the problem that the idle AC current is read with 400mA. After connecting a load e.g. pump or refrigerator the values of the AC current will go back to real values.

Since correct values are read out when the load is connected, I do not think it 's a problem of the "solaranzeige" solution.

Also I tried to read #VE_REG_AC_OUT_APPARENT_POWER but I got always a static vaule of Hex: 705220225

I hope I can get help from the community here.

Many thanks in advance.

And best regards from Germany

Replacing/Coexisting Sargent campervan components with Victron

Good evening,

We are looking into upgrading the battery and solar panel system of our campervan and for that purpose, we think we will need to replace some Sargent components with Victron components.

Currently, we have an 80W solar panel, connected to PWM Regulator (
The regulator is connected to a EC500 Power Supply Unit (
The EC500 PSU can be controlled with EC480 Control Panel ( The control panel can be used to monitor the solar input for the solar panel, the status of the vehicle battery and the leisure battery. It can also be used to switch the charging from leisure battery to vehicle battery.
Finally, the EC500 PSU is connected to the PX300 charger ( that is connected to the battery (Lithium LiFeP04 Professional 12 V 110 AH)

We would like to know the following replacement/installation is doable and what product should we aim for?
1) A new Victron MPPT solar charge controller that can handle up to 2 x 100/120W solar panel
2) The output of the Victon MPPT should be fed into the EC500 so that it can be monitored by the EC480
3) A new Victron battery charger that can support up to 2 x Lithium LiFeP04 Professional 12 V 110 AH in parallel (or the vehicle battery). The output should be managed by the EC480 so that it can be switched to charge the 2 Lithium batteries or the vehicle battery as it does today)
4) A new Victron 1200W pure sinus inverter where the output is connected to the EC500 in such a way that the existing 220V sockets in the van can be used with normal appliances (in the same way as connected to the mains)

Any good suggestion is most welcome.

Thank you!

Victron Phoenix 12/375 inverter settings with Battle Born 12V/100Ah LiFePO4 battery

In case anyone is interested, the manual for Phoenix 12/375 (and other smaller Phoenix inverters) lists the following:

Low battery shut down (adjustable) 9,3 VDC

Low battery restart & alarm (adjustable) 10,9 VDC

Battery charged detect (adjustable) 14,0

I called Battle Born to ask as this didn't seem right for the LiFePO4 battery, and this is what they told me:

Low battery shut down (adjustable) 11-11.5 VDC

Low battery restart & alarm (adjustable) 0.5V higher than shut down - 11.5-12 VDC

Battery charged detect (adjustable) 13.2 VDC

I've set up my inverter like this, will see how it goes over the next 5 days out camping.

Hope this helps.

Phoenix inverter 24/1200 alternately blinking red &green

Handcarried this inverter to Philippines for my solar plant (24V, 200Ah lead-acid battery, min 25.2V max 28V, PWM controller, new battery, 50mm2 cables 1.5 meter). Worked brilliantly for 2 weeks at 60Hz, 230V. There was no internet connection.
2 days ago, there was an internet connection and the software updated automatically, no problem. The unit powered an inverter washing machine @ 650W max.
The inverter gets shutdown for the night. Next morning, the red/green lights started blinking alternately in 1 second tact. No output. The input voltage is min 25.2V and max 28V (measured with a Fluke at the inverter connections.
I cannot take the inverter to the dealer, a bit too far. Can somebody please give an indication what the blinking lights might mean and how to correct it? Thank you!

Phoenix 12/1200 switches AC output in ECO mode without any load connected

Hi guys,

I've got a new Phoenix 12/1200 inverter here and wanted to connect all the necessary devices for my VW T5 outside the car first. Everything seems to work fine, the Phoenix outputs 230V when it is set to "ON".

But when I set it to "ECO" mode the output is switched after a few seconds and then immediately switched off again. That continues until I switch to Phonix "ON" or "OFF".

I connected the Phoenix DC input to the battery (which shows 13.4V at the moment) and the external earth is connected to the car's earth. There is no other cable connected to the Phoenix (even on the output side, there is not connected anything!) and the configuration has not been modified.

Any hints why the Phoenix is doing this and how can I fix that? I want it to activate the output when a load is hanging there.

Thank you very much!

Does the Phoenix 12V 250W inverter spew out large amounts of RFI?

Hello all, just a simple question can anyone let me know if the Phoenix 12V 250W inverter causes RFI if using it to run an AM/FM radio? I would also be intrested if anyone has experience of using this inverter on the HF/shortwave bands.

My experience with cheap pure sine inverters is very negative as I have had such units completely wipe out all radio transmissions even from extremely strong local stations on all bands as well as causing laptops to behave very strangeley by producing odd keyboard/mouse behaviour so I'm looking for peoples experience with the Phoenix 12V series with laptops and radio gear.

Thank you.

Someone please answer. Pylontech US2000 2.4KWh + Phoenix 1600/2000 Smart + Venus GX

This is my second attempt at getting an answer. No one answered the first time...

With a single 2.4KWh Pylontech US2000 Module and Venus GX will the Phoenix 1600/2000 Smart work?

I have read the manuals of the Phoenix 1600/2000 Smart which seems to suggest two modules would be required by the minimum recommended battery size (Section 4.2). Phoenix 1600 (75Ah-200Ah). Phoenix 2000 (100Ah - 250Ah).

However at the following link:

The Battery peak discharge watt rating in section 2 (Minimum Battery Sizing Recommendations) seems to suggest that one module would do it.

Of course I am speaking about 48V versions of all related equipment.

Control board is faulty in an old Phoenix Inverter, to confirm I have replaced the board with a Multiplus control board of the same rating. The Phoenix Inverter is now working under load. The LEDs are flashing on the control board as expected as there is no charging function on the Phoenix Inverter.

The out of warranty unit is now working and whilst not ideal, is there a problem with this set up long term?

The quattro wil turn on for 7 seconds then


it will drop AC OUT power for 12 seconds then the cycle would repeat itself.

The ESS configuration is correct and a copy from other sites.


There are no alarm logs, no notifications and the system worked well for 3 weeks.

Can older Phoenix 48 800 be adjusted voltage wise?

I bought this style unit

Because it can accept significant higher input voltage (68V) than the successor at 62V or something. It works perfectly with my 60V electric scooter battery if it is charged to only 80 percent or so.

Only trouble is it will drain the battery too far down if unsupervised. Is there any way to adjust the input minimum voltage to around 57V so it shuts off as the more modern units can be adjusted to via app?

Warranty has been voided before so no concern there. Cheers

Good USB Hub for CCGX with low power draw or Relay shutoff for inverter?

I use a CCGX, BMV-702, 3 MPPT's, and 1 USB wifi dongle.

Since there are only 2 VE direct and 2 usb ports, I need a usb hub to get my 5th connection point.

Currently, I have a crappy AC powered usb hub on the old phoenix inverter (That doesn't have ve direct port, Insert angry face) and the inverter is in ECO mode.

The USB hub is the only AC load on my boat, and I only really need it to send the wifi to check the system.

Is it possible to use the relay on CCGX or BMV to turn off phoenix inverter using it's remote port at night, when I don't need to check the wifi?

Or should I just find a low powered USB hub that runs on DC? (Does anyone have any recommendations?)

Every night, my BMV says 100% but the AC inverter is powering the USB hub through the night, and it uses about 2% of the bank and 96 watts. Is this slowly killing my batteries? Should I not be worried about this daily 2% discharge?
