Hi, I am just trying to get my head around this and wonder if someone can confirm it please?

For a 12-15vdc battery off grid system needing to charge through a charge controller via a solar panel array of course which the panels are rated at around 55Vdcmax.

With the cheaper Ebay MPPT controllers (link to example type bellow), they cut off the solar panels inputs if the solar panel voltages are above around 15Vdc, so effectively the panel would only charge the system when the panel voltage is within the 12vdc - 15vdc, effectively only for a VERY short time in the morning and again at sunset.

With a Victron charge controller like (link of example type below), to charge the 12-15vdc from the panels (55Vdc). Does the Victron charge controller cater for the full 0-55vdc from the panel or does it also have built in cut out solar voltage cut offs, resulting in the same issue as the cheaper Ebay charge controllers?

I guess I am looking to have some device which converts the 0-55Vdc to a more usable 12-15vdc range so as to charge the batteries. Is the Victron charge controllers able to do that, regardless of the voltage from the solar panels are producing?

Kind regards

John.

• I have a set of 4 135amp led acid flooded batteries and no electric hookup for a inverter/charger. My batteries voltage seem to drop quite quick in the evening. When I test charging from the solar system and batteries from the controller all seems OK. From the alternater to the battery seems OK too. When testing the acid level shows as needs charging but when my engine is running the monitor suggests they are 14.4V

Rather than trying to get the batteries out to put them onto a 7 stage battery charger I believe there is a high output alternater with a 3 stage charging system involved. How do I find out which one I need with my current set up? Think they just need to have that good charge but they are too heavy to be lifting in and out of the battery bay every time it's needed

I currently have 4 Solara 140W solar panels on my boat with a single Outback FlexMax 60 charge controller. I also have the Outback Mate 3S and FlexNet DC, which provide monitoring and data logging, along with multiple shunts.

I'm trying to figure out the best design (and parts) to replace the Outback stuff with Victron equipment.

I understand that due to potential shading, etc, I will get the best performance if I have a dedicated controller for each panel.

Here are my needs and what I think I need. Would really appreciate some assistance in validating this stuff. I've contacted a few resellers, but beyond the simple stuff, like just the controllers, none of them have understood my more advanced requirements.

Requirements:

- I want to have a dedicated solar charger for each solar panel.

- I want to be able to monitor data via TCP/IP (I will write custom code to grab data, but it needs to be network accessible. I do not want to reply on the portal as oftentimes the boat does not have internet access, but the internal network where my login server is located is always online). Data includes solar data generation parameters, battery consumption (see below), battery voltage, battery temperature, etc. I understand the Victron Venus GX data can be accessed via ModBus TCP

- I want to be able to monitor AH added to battery and AH used from battery. I have multiple ways of charging the batteries (solar, AC chargers when docked, and engine alternator). My current system has shunts that monitor these "inputs" as well as the usage from the battery bank. I want to monitor the AH production/usage for all of these individually and collectively.

- I need to be able to configure the charge profile for my type of batteries (12 x Firefly Group 31)

- I want to be able to make changes to configuration remotely.

- I also have Raymarine MFDs (Axiom Pros) that would be cool to integrate

- Space is at a premium, so I need to use the smallest physical gear possible

Equipment I "think" I need:

- SmartSolar 75/15 x 4 (one per panel)

- Venus GX

What I don't know...

Neither of the above has a battery temperature sensor that I could see. How do the charge controllers know how to compensate for the battery temperature?

What about the shunts? Can I reuse the standard 500A/50mV I'm currently using or do I need to replace them to work with Victron.

Any input would be greatly appreciated. Would love to find a vendor who understand the higher level requirements of network monitoring, etc.!

Good day,

I have a problem with the 48/3000 and 48/5000 multiplus inverters.
In the Czech Republic, the central remote control is used. It is used for switching boilers, heat pumps etc.
At my location it is broadcast on 216.6Hz over power lines.
The problem is when using the ESS Assistant.
When the remote control datagram is broadcast, the inverters stop charging or inverting and pass to passtrough.
Is there any solution? new FW?
Thank you
Pavel

I'm currently setting up my multiplus with a breaker box on AC1. The grounding instructions don't address a detachable generator if not in a vehicle with a chassis to ground to. Any suggestions for grounding the system with a detachable generator in a no vehicle environment?

We have our system setup and have been using ESS for years now. We have critical loads on AC output 1 and non-critical loads on AC output 2 so that critical loads continue to receive power during grid outages. Today for example we have a scheduled power outage for the whole day.

We have more than sufficient PV/battery power (over 2500w) now to also power the AC output 2 loads (around 1200w).

Is there a way to manually enable AC output 2 during such times? If not this might be a nice feature to add to the ESS settings on the CCGX.

This is what is currently being used without anything on AC output 2:

[image]

I have manually plugged in a few items into the AC output 1 circuit to show what is actually available on PV:

[image]

I have Multiplus 3000, Venus GX, BMV712 and Lithium Battery Bank. Is it possible to use temp from BMV712 to turn off charger with low temp to help protect Lithium battery?

Is it possible to measure AC-out 2, so it is displayed seperately from AC-out 1?

I want to see both AC-out 2 and AC-out 1 on the remote console?

Hi all

I have:

• 1x Quattro 48/8000/110-100/100
• 1x CCGX
• 2x Solar MD 3.7 with DataloggerV2
• 2x Solis 4kW G4 1ph Grid-Tie Inverter, each with a ET112
• extra ET112 for measuring AC-OUT2;

I want too:

• See power output on essential and non-essential loads on CCGX and VRM;
• be able to close the relay on AC-OUT2 in an off-grid environment (load shedding) and power non-essential loads if there is enough power available from PV;
• In On-grid periods power both AC-OU1 and AC-OUT2 with PV first;
• Only charge batteries from PV

I want too see who has done something like this, and get feedback and collaborate please.

Issues arrived:

• Will the Solis inverters give an error during in off-grid if a CT clamp is configured? The theory is it should use the CT clamp during on-grid and frequency shifting from the Quattro during off-grid to regulate power output. Was advised it should not give an error, will give feedback, we are close to powering up the PV;
  • Since i started this post some feedback came back, Solis said there is a 'Fail-safe - Disabled" i have to select to avoid this error;
• I am using ESS, so non-essential loads is displayed as next to the grid with an icon on a CCGX, which is fine. Please correct me if i am wrong, but my understanding is that ESS wants to only use AC-OUT1 with a ET112 on the grid input, so all power via inverter will be considered essential loads, and the difference between that and the meter, will be displayed on non-essential loads. Since my requirement is to power AC-OUT2 loads in daytime and if the PV is strong (still not sure how we will be configuring this, will get to it later) I had to connect the non-essentials on AC-OUT2 instead of leaving it on the DB as the manual suggest. My biggest question is how do i program the CCGX to display the AC-OUT2 on the CCGX/VRM with a ET112? The only options are inputs (Grid, Generator and PV Inverter, the last one i will be using for the Solis PV Output).
• Assistance to program the Quattro to only charge batteries from PV;
• I found assistance to program AC-OUT2 to close during Off-grid here: https://community.victronenergy.com/questions/1343/enabling-multi-ac-output-2-during-grid-outage.html

I did possibly miss something in the manuals, so please just direct me to the correct one should that be the case;

My question is regarding the frequency via the isolation transformer, if input 230v 60hz, output 115v what will be the hz 50 or 60

Hello,

I have 3 identical standalone systems installed in the last 2 weeks that are not calculating the SOC correctly.
(NOTE. This has never been a problem with dozens of other installs over the last several years & I suspect a recent firmware update issue but please tell me I'm wrong).

As you will see in the VRM data below, the SOC is gradually reducing each day, however the MPPT is clearly reaching float.

In the past we would slightly reduce the VEconfig absorption voltage & Float Voltage to below the MPPT charge settings (& below what was being reported in VRM for the VEBUS DC Voltage). The Multi would then "Force" SOC to value set in VEConfig resulting in regular syncing and doing a very good job.

Equipment & Firmware:
Multiplus 2 48V 5kVa - firmware 467
MPPT 150/100 Smart Solar - firmware 1.47
CCGX - firmware 2.42
No BMV Battery Montitor
No External DC Loads
No AC Coupled PV Inverters
Lead Acid Batteries

CCGX Settings:
System has Multiplus 2 set as battery montior
Note. The option "improve VEBUS SOC with Solar" is no longer visable as of a recent CCGX update
DVCC turned off

VE Config Settings:

General Tab
-Battery Monitor Enabled
-SOC when Bulk finished - 95%
-Charge efficiency - 0.85

Charger Tab
- Absorption Voltage - set slightly below MPPT voltage & voltage reported in VRM for VEBUS DC Voltage
-Float Voltage - set slightly below MPPT voltage & voltage reported in VRM for VEBUS DC Voltage

Note. I have adjusted all of the VEconfig settings several times trying to get the system to work with no success.

I have an Orion Smart 12/12-30 in charger mode in my car. Since I have it connected to my battery, it is the first time the car fails to start.

Even if it detects motor stop correctly and thus should stop current flowing from the source battery to the input, can it be that this device drains my source battery while having bluetooth on?

I did not see this device flashing any leds when input is disconnected but has fully charged batteries on the output circuit side. Does the device consume it's standby power from the input ciruit?

I have 6 of these controllers. For 2 years this one controller has always gone schizophrenic every 10 minutes. Before I replace it I thought I'd post some screen shots. I suppose it could be a bad panel, but my guess is its the controller. The pic on the right is a 13 minute run. The left is a close up at 3 minutes. Exact same pattern every time.

Hello All,

Ive recently installed a Multiplus compact 24 2000 50-30 230V and have found it will not power up and charge off of its diesel powered genset at 240V 50Hz . It previosly worked when powered up on the bench on a different set of batteries at same voltage.

No alarm LED no Charge LED lit 240V supply is ok and output is connected correctly to 24 battery bank .

Its installed as remote power - i have no way to update firmware or communicate to the charger.

Hello

The default float voltage on my EasyPlus Compact (12 volt, 1600 watts, 70 amp) is 13.8. This is too high for my LifeLine AGM batteries which require a float of 13.4 volts.

The float voltage can't be changed using the dip switches and the VE Configuration tools for VE.Bus Products software download that is available on the victronenergy.com web site only runs on Windows and I have a Mac.

Given the above, how do I change the float voltage?

Thank you

On the 500amp/50mva shunt there is a temp sensor wire connected to the B1 (red) and B2 (black) position. My system has two battery packs. The second battery pack is not monitored by the BMV 712 guage as it is downstream of the shunt. If I remove the temp sensor wire and install two power leads, one to B1 and the second downstream battery pack to B2 will the BMV 712 include both battery packs in it's readings?

New charger worked fine out of the box, 2 weeks later it cycles (clicks) every few seconds and only about 1 amp output and about 4 volts shown on app... Should be around 27 volts. Lights show Bulk and LiPo, as they should, but not getting 7.8 amps like I did initially. Batteries are at 80% and 60 degrees. Same results using 3 amp output setting. Smart BMV shows spikes on the graph matching the clicking.

Hi!

Is there a document describing the blow speed / excess current relationship for the different Victron fuse types?

thanks

I have a BlueSolar MPPT 100/30 V1.30 with the dongle and it works fine I just bought the Smart Battery Sense and got it networked. Now when I try to add the MPPT to the same network, I don't see the option to add it to the network under settings. I played the video on the Smart Battery Sense and I don't see all of the options it shows. Is there a firmware update I need? Is it the V1.47 I read about in your docs?

Everything has been working fine since installation 2 years ago. Now when opening VE app on either my MacBook or IPhone it discovered the device but gets stuck loading at 20%. Have followed support protocol to reset password but there is no option to actually choose a new password in either format! Have also unpaired device from Mac Bluetooth but this changed nothing also. Please do not send me back to the troubleshooting manual as I have followed its suggestions and no luck. I am fine with using device with either Mac or IPhone, does not have to be both. Any suggestions greatly appreciated

Hi all,

Could someone tell me what kind of "regular" communication is between Venus GX and BMV?

Planned system: MPPT+BMV+Phoenix C + Normal battery + Venus GX ( DVCC + SVS)

Why? I would like to use a monitoring of serial line between BMV and Venus GX (RX line from Venus GX point of view) for regulation purposes ... as a robust way ...

And ... I would like to be sure before buying of BMV and Venus GX ...

A) Is it Master (Venus GX) - Slave (BMV) communication (Victron HEX)? What is the request's frame rate?

B) Is it a type of broadcast communication of BMV (Victron simple TXT)? So Venus GX has every 1s updated information?

Good day.

When accessing the connected Color Control unit, we found that the inverter had been overloaded.

We were aware of the first instance, when it occurred inadvertently, but it has since happened on several subsequent occasions!

It MIGHT have been due to somewhat overcast conditions(?), but the battery bank was fully charged, and we assumed that the very short usage of whatever equipment, would/could be supported by the battery bank?

However, this is of lesser importance.

The Color Control indicates that "history", in this case the overload occurances, must be cleared on the "unit" itself?? We could not find any way to clear the overload history on the Color Control, NOR on the BMV700?

How should this be done on either of the units?

I am a first time Victron customer and have installed a 6kW Solar array into 250/100 MPPT solar charger feeding a 13.5kWh LiPo Balancell battery, and a Quattro 48/8000/100 Inverter charger linked to the grid and critical loads.

I have setup the battery voltages as per the supplier specs, but neither the solar charger nor the Quattro will charge the battery, but reach and maintain "Float voltage" without charging. The battery shows a 30% SOC at around 51v and "float" at 56,5vdc but idles at 0,5 A

Any ideas as to where to correct the setup??

My system: Multigrid 48/3000/35-50 with Venus GX and two connected Pylontech US2000 Plus. A BlueSolar 150/35 is DC- connected to the Multigrid. My Fronius Primo 3.0-1 is AC- connected to the output 1 of the Multigrid. The gridmeter is an ET340.

Now i want to feed in the excess energy to the grid after loading the batteries to refinance my pv- system. If i want to get my feed in energy payed i have to register my system by an electrician to the energy supplier. There is a law in Germany called EEG: Only feed in 70% of all the generators maximum power output. The electrician have to set and confirm that the maximum power feed to grid is set to 70%.

Without this limitation to 70% on the entry point to grid you have to install a radio remote controller to govern down your system in four steps by the energy supplier in case of over- energy of the grid. This controller costs about 1100€ and monthly 5€. Last choice is to cut off all inverts to 70% of power generally.

Further information see: http://www.buzer.de/gesetz/11230/a188267.htm

The technical system and measuring devices are installed, available and working fine at the ESS. Other possibilities to limitate to 70% means an huge technical effort to the whole system and money or a loss of energy.

The Fronius and BlueSolar MPPT can be governed by the CCGX to zero feed in to the grid (works fine) but there is no possibility to govern it to a adjustable max. feed in to the grid.

I need a function to set the maximum power (50W steps) feeded to the grid by the ESS.
Priorities: 1 = self consumption; 2 = loading batteries; 3 = feed to grid with adjusted maximum power
This is an important function to use this system in Germany to feed in to the grid.

I don`t know the exact conditions of the network operators but password protection for the max. feed in value will be necessary.

Is Victron planning such a function?

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.

My system is a new system based on two Multiplus II 3000/48 connected in master/slave, two 150/45 MPPT's, CCGX, and a BlueNova battery connected via Canbus.

I have the latest firmware installed on the MPPT's, Multi's, and CCGX.

When the system is physically disconnectted from the grid it is functioning perfectly supplying the critical loads and charging the battery during the day and running off battery at night.

I'm currently trying to implement ESS.

During the day when the contribution from the MPPT's exceeds the AC critical load it functions as expected in charging the batteries and supplying the critical loads.I have set the grid setpoint to -20W to always have a slight export to the grid.

However as soon as it starts getting dark the inverter switches to passthrough mode and supplies the load from the grid even though the battery SOC exceeds 98%.

Are there any other settings on the CCGX or the Multi's that I am missing?

My solar system consists of the following setup

Victron Color Monitor GX firmware V2.42, Multiplus 48/5000/70-100 firmware 413, Battery Monitor BMV-712 smart firmware V4.03 charged voltage 55.4V, smartsolar charger MPPT 150/85 rev2 firmware v1.47 absorption voltage 55.7V float voltage 55.4V, a battery bank of 24 maintenance free batteries each 2V with the following specs Float 2.23-2.25V Boost 2.30-2.32V Current 60 to 120Amps, 18 Solarworld panels each 290W

The challenge am facing is over night the batteries discharge up to 75% and when the sun rises, the batteries charge up to 90% and the charge controller moves from bulk direct to float and skips absorption stage so the batteries don't get fully charged they only charge up to 95% with full 8 sun hours, what could be the problem with my solar solution

Hello

I have the trouble to set the correct temperature correction value for a bluesolar ( firmware 1.16) 100/50. I have a 24v battery bank with two of this 12V batteries in serie. The manual indicates -30mv/K temperature correction for the cycle use.

Is it correct that in my case with 2x12V batteries = 24V bank I have to set the temperature correction to 2*-30mv/K = -60 mv/K?

The bluesolar doesn't accept the -60mv/K temperature correction value.

Is my calculation bad?

Thanks

I'm installing a MultiPlus 12/3000/120 in my RV trailer.

I'm testing as I connect things - the first test after wiring up the fuse and battery disconnect is to be sure that it's inverting and making 120 VAC. But no 120 VAC present at the AC1 terminals.

I have the MK3 USB adapter and tried to download VEConfigure, but what I got was Victron Connect. It seems to be working and allowed me to update to the latest firmware though.

Victron Connect does say that the inverter is inverting. I don't have any power going in the AC In terminals yet.

I don't have AES on. Should I see 120 VAC on the AC1 terminals or do they need to see a load?

question regarding placement of the Lithium should there be a space Air gap around each battery any min requirement ?
