If battery is fully charged, shouldn't load provide power at night?

My battery is fully charged.

For testing purposes the Load setting is set to "Always On"

When the sun goes down there is no load output.

I would expect power to feed from battery to MPPT and out the load terminals.

What am I missing?

Thank you.

MMPT RS 450/100, MP2 and Fronius

Hello to all,

I had the following “On grid” configuration:

  • 1 Fronius Symo 10.0.3
  • 1 Multiplus 2 GX - 5000/48 “hooked” on phase 1
  • 1 three phases Smartmeter
  • 1 Smartshunt 500/50ma
  • 220 Ah Li Ion batteries
  • 18 solar panels 370 wh each in two strings – 10 on one string and 8 o the other. (intention is to install another 10 panels)

As this year the grid electricity starts dropping every week (they are replacing the old network) I decided to get an MPPT 450/100 to make it work in parallel (Off-grid during the electricity outages) therefore I disconnect the 8 panels string from Fronius and I connected it to the MPPT.

MPPT and Smartshunt are connected to the MP2 via VE.Direct.

The main issues are as you can see in the prinscreen of VRM or console:

  • When there is a high load, the system is getting the power from the batteries and the MPPT goes to 0
  • Is throttling the Fronius inverted to 50-60% of normal production and is getting the difference from grid.



The funny part is that if I am connecting to the MPPT via Bluetooth or in the console and I am looking for the production of MPPT is shows about the right amount but somehow this is not showed in the VRM neither console Pages. I have no idea which ones are the right values.

Is this the correct use of the BMS CL 12/100 in a van system?

Hi everyone,

I can't find a lot of detailed information on the Smart BMS CL 12/100 and was hoping for some insight on how I've applied it to my system. The main reason I wanted to use it was it provides more amperage than the Orion.

(I have yet to add wire size, fuses and breakers to my diagram)

Any help, insight or suggestions would be greatly appreciated.

Lots of problems with ESS multiplus 2 (error 24)

I Installed a multiplus 2 with 10kWh of BYD batteries in an ESS system first half of the year, it worked well for a month or two then started bringing up error 24, I followed the instructions for what to do for error 24 and sent them off to my victron distributor, victron decided to send me a new unit, I intsalled the unit and instantly had the same problems, after lots of return visits and firmware updates in the hope the issue had been found and resolved which is costing me lots of time and money ive realised that the unit will go straight into error 24 with the current sensor plugged in, If i remove the sensor and restart the unit it starts fine then plug it in it begins to act as an ESS system should with no error code, the problem being that i simulated a power cut by turning the AC isolator off and then back on, and as the sensor is in it goes into error 24, i have updated the firmware twice and replaced the unit. Its a real shame as its also costing the customers confidence in the system i have installed for them, and I cant keep going back to resolve this I have seen on the VRM it is in error 24 again today and i went to them on friday. It has the latest 2629 467 firmware intalled and the UK G98/G99 grid code. Please can you sort a resolution for this ASAP.

What victron charger for lifepo4 + lead/agm? + Argofet question.

I am planning to upgrade the 12v house bank in my boat to lithium. In the process I need a new 230v charger, with 3 outputs to charge this new lithium bank, plus agm starter batteries, plus windlass/thruster battery.

looking for high capacity as well as keeping it on more or less constantly to maintain and keep all batteries topped up and in good shape.

the Skylla 12/70-3 was recommended to me but then I was warned that it would not cope with batteries of a different type.

Also, I already have the Argofet 200-3 mounted, and it works great. But again, someone said it would not work with one battery bank being lithium. As that bank is so power hungry the theory is that no charging current from the engine will reach the two other banks until the lithium bank is full.

Is it true? Or will it work? This lithium upgrade is turning into a headache before it started.

Is it safe to turn off a MultiPlus under load via VRM?

I have a MultiPlus 24/2000/50 connected to a VenusOS device which allows me to connect to it via VRM.

About the only thing I will be using with the inverter is a small air conditioner that uses 420W while the compressor is on.

Is it safe to connect to VRM and tell it to turn off my inverter while the A/C is running? This is just incase I end up being away from the trailer unexpectedly for a few hours and realize I left the A/C on.

Cerbo GX connection to multiple MPPT not parallel

Hello everyone, I am almost confuse about to monitoring 3 MPPT Smartolar charge controllers that we are going to connect to the Cerbo GX. Because the solar installation is more than 20 years old, "unfortunately" we have 3 string of solar panels connected with 3 battery banks and after by schottky diodes to the load (MM.WW. system), but we can´t optimize the banks because the space of each one is limited to joint them on one battery bank. for that reason we should monitor each MPPT Charge controller separately. Is it possible to monitor each MPPT (PV power, BAT power and load consume) or each MPPT should be connected to a GX device?.

Thanks for your support.

DC Leakage via Protective Earth Conductor

I'm have this weird problem that during a no-load condition with an Smartsolar MPPT charging, I'm seeing a phantom load of around 22 W that doesn't seem to exist. The MPPT is mounted in a cabinet along with a Multiplus, and the whole cabinet and both devices are tied to a protective earth bus bar, which is bonded to battery negative, aka before the SmartShunt in the system. The Multiplus and the MPPT are then grounded on the load side of the SmartShunt. I also measured the current in the earth conductor, and it's around 1.4 A, which correspond quite well to the 22W phantom load on the system (12V system). There's also an equal discrepancy between the battery + and - conductors of the MPPT. So, is there an issue with my MPPT charger, or should I bond the protective earth bus bar on the load side of the SmartShunt?

Multiplus II Questions - Humming and adding power with other inverter

Hi. I am the lucky new owner of a Multiplus-II 24/3000-70/32. Just installed it and started using it. I have two questions, the first purely informative and the second more practical.

1. It's humming loudly (relatively). The less load on the inverter the louder. As I go long days with low loads (50-250W) it seems that it will be humming a lot under my ownership. I'm just thinking - sound means vibration and vibration means wear. How will all the solder joints, capacitors and everything hold up with that constant vibration. Maybe I am just paranoid but no other inverter I have used before have had that kind of hum constantly. Can someone put my mind to ease about this and explain if it is just the way they are designed and that it is ok, or otherwise?

2. I have PowerAssist in this inverter which is supposed to combine the inverter ac current with incoming current from the grid or genset if needed upon high enough demand. I have a 900W 24V sine wave inverter from another brand laying around. I wonder if, in the situation I needed it, I can connect that other inverter to the battery pack and feed it into the multiplus to get 2400+900=3300W? Is that a dumb idea or a reasonable thing to do in a pinch?

Best Regards,

Buzzing sound Phoenix 12/1200 inverter


I have an Phoenix 12/1200 in my motorhome, and it makes a buzzing sound when it`s turned on. And when I put a load on it, when charging our e-bikes with 160w AC, the buzzing gets really high.

I did return it to the seller in Germany, But they said it is like that with Victron inverters… so they sent it back to me and they also send me some rubber ”feets” to put between the inverter and the wall so The sound dont get amplified from the wall

Is this normal?

is there anyone else with similar problem?

Bluesolar MPPT 100|30 conflict with MPPT 150|70

I have an MPPT 150|70 charging my batteries and connected to CCGX.

I have a backup solar units connected to an MPPT 100|30 connected to the batteries.

as long as the MPPT100|30 is not connected to the CCGX I can see the MPPT 150|70 on the CCGX and it work properly and I can connect the MPPT 100|30 to my laptop using Victron connect and see that it is working properly.

But once I connect the MPPT 100|30 TO THE CCGX it takes few seconds and I get error# 66 (incompatible device) on the MPPT 150|70

I can't clear this error message.

It looks as if both controllers continue to charge.

The firmware:

CCGX= V 2.72

MPPT 150|70= V 2.00

MPPT 100|30= V 1.56

To my best knowledge these are the latest releases of the products firmware

Is this message a real problem?

If "yes" what is the problem and how to fix?

If it is not a problem how do I disable and remove the error message?

MPPT 100/30 float issue

Hi all,

I've had a look through the masses of previous questions and unfortunately couldn't find any that were quite the same as mine.

Recently I have noticed that my SmartSolar 100/30 completes it's bulk and absorption stages and enters float mode. When in float it will match any current draw from the battery for roughly an hour and then will suddenly no longer keep matching the battery and it will then start dropping down from 100%.
It says it is in float mode, there is plenty of sunlight and panel voltage present, however it doesn't output any charge to the battery. No other chargers connected to the battery.

I have the float voltage set to 15.8V and even when the loads connected to the battery increases it does not kick it back into bulk.

I then have to reset the controller by disconnecting the solar, then battery and reconnecting, which it will then it go back into bulk mode, absorption mode and then eventually into float again.

Has anyone else experienced this issue? Is it potentially a firmware issue?

Can a CCGX be used with a Venus GX

We live on a boat. We are 12v and mainly on shore power. Currently use VRM or bluetooth to get information from our Venus GX.

However, to keep my wife happy she has seen the CCGX which is the same as what we have except ours is either through our tablet or PC. She would like me to fix a screen like the GX Touch or CCGX, so she can just press a button and have the information to hand. Yes I know we already have that information via VRM/web/bluetooth, but she has seen the CCGX on someone else's boat and wants the screen fitted to ours, or a similar Victron product that has a screen.

Can I fit a Victron product like the GX touch 50 or CCGX and plug it directly into the Venus GX which already has everything plugged in and receive the same colour screen infor.

Matching SPD to MPPT

This is a question I have been discussing with colleagues and there seems no clear answer.

I have noted that most of the SPDs on the market are either Uc 600VDC, 1000VDC or 1500VDC. But our MPPTs are 150V MAX, 250V MAX or 450V MAX.

It seems thus, that a 600VDC SPD might protect something in the system against over voltage but that would not include the MPPT which would be exposed to over-voltage before the SPD had begun protecting (Uc).

Should we not be getting 145V, 245V and 445V SPDs manufactured which match the Victron products to properly protect MPPTs against over voltage? I have spoken to a manufacturer willing to do this but MOQ is 250 units which is a bit much for me to "test" the concept with.

Any insight would be valued.

BMV-700 what am I missing

My system includes Multiplus charger inverter, CCGX , BMV700 , Shunt and the AGM batteries.

All equipment is Victron batteries are Lifeline AGM.

All equipment is connected on the "load" side of the shunt only the batteries are on the battery side.

When I shutdown the charger the BMV-700 and the CCGX show -4.5 Amp which to my understanding indicates that the batteries are being discharged.


When I turn on the Multiplus charger inverter it can for example show on the CCGX DC current of +30amp but the BMV-700 on the CCGX continue to show almost the same current around -4.5 amp.

While I expected it to show +25.5 amp.

It is clear that I am missing something since I know that the charger in fact charge the batteries and it is connected on the "load" side of the shunt.

In fact I think that the BMV-700 always shows minus values for current.

I appreciate help understanding this issue.
