After installation with the switch in CHR position, the charger does not start after connection to the shorepowergrid. All leds were off. After disconnecting shorepower, and the switch to ON the inverter started. After this the charger also worked. However, the problem is now back: charging is okay but inverter refufes to start. All LEDs off and plenty battery power. Is this a product failure or installation issue ?

It would be good to have an updated list of Wifi modules that the CCGX supports. Because the article about it on the Victron website (https://www.victronenergy.com/blog/2014/12/12/color-control-gx-accessories-tips/) is almost 3 years old and for example the ZyXel NWB2105 isn't available anymore!

I tried 3 other USB Wifi modules: 1 works, but doesn't fit in the CCGX housing (Sitecom WL-344), 1 doesn't work (Sitecom WLA-2100 v1001 > no driver support, isn't recognized), 1 sort of works, but is very slow and unstable. (Generic Nano USB)

Could someone please provide the brand/type specification of a few USB Wifi modules that work with the CCGX and that are generally available. (I am curious which USB Wifi module Victron uses in house for testing purposes at this moment.)

What would help me (and other users) mostly is the specific brand and type of USB Wifi module that 100% works well with the CCGX and is generally available at this moment in time.

I have been trying to figure out which currently available USB Wifi module is a good replacement for the ZyXel NWB2105 (antique by now), but the "buy-and-test" approach is costing me a lot of money and time, as I am down to my 3rd module that doesn't work...

If other users have good tips (with a link to the shop that sells them. I am in The Netherlands, BTW, but we should aim for a Wifi module that can be bought everywhere), that would be appreciated as well! ;-)

Thanks in advance! :-)

The CCGX is not seeing my dongle. i am running the latest firmware. is there a trick to this ?

Hi,

Equipment I already have:

160W 12V solar panel

275W 24V solar panel

210ah 12V gel battery

Two Victron BlueSolar MPPT 75/15 charge controllers

Planning to connect one solar panel to one controller and the other solar panel to the second controller and then both controllers to the same battery.

My question is: should I connect all my loads to one controller only or can I connect some loads to first controller and some to the second? These controllers have max 15A loads and I wonder if I can connect more than that to two of them? For example 12A load to one controller and 14A load to the second?

Will the two controllers still be able to monitor the battery state and charge it properly simultaneously?

The average load I plan on connecting will be around 500-700 Watts maximum, with the occasional exception when a 1100 watt microwave is being used (typically 4-5 minutes at a time as most people do a microwave). Grid power is very stable, so most of the time this would be running in ESS mode with PowerAssist, but if the grid ever would to fail, and someone forgot not to run the microwave on battery power, I am interested in knowing the specific overload conditions of this inverter. I have heard people state that the 5KvA model can output 10,000W for "several minutes", which is over 200% its normal maximum continuous rated output. The MultiPlus 2000 is rated at 1600W continuous, so I am wondering what a load of 1800W (~113% maximum continuous output rating) might do over a period of about 5 minutes.

I have Pylon batteries connected to my MultiPlus-II 48/5000.

The batteries are fully charge at 53V and I did set the MultPlus-II settings as stated in the Victron & Pylontech US2000B Manual, VEConfigure Settings.

The Multi Battery LOW RED LED is flashing and if I disconnect main, the Multi switch off after 30 seconds because of low battery even if the battery is still 53V.

What am i missing??

hey guys actually i was trying to make my solar system works properly, but my filax advise me that it doesn't receive the priority source, so it says: "priority source fault" what should i do?

Yesterday I had to reset the network settings on my iPhone. As a result, I had to retype the password to reconnect to the Venus GX. I was looking for the manual that contains the password, and I think I lost it. Does anybody know if the password is also written on the unit somewhere or if I need to reset it? If yes, how?

I just purchased a Canal Boat [I take possession in about 10days] and need to comprehend the energy use for the large amount of installed appliances [fridge, freezer, washer, dryer, electric water heater, 220 TV's]. I plan on installing a Victron BMV 700 series battery monitor. Not sure which is best. There are two starter batteries and two leisure batteries. Will the 700 do both battery sets or do I need the 702 or some other unit. Do all monitors have Bluetooth capability or do I need a specific model for Bluetooth?

I do plan on adding solar once I have more power use information.

I have a 230V Quattro running on a 200Ah 24V lithium (Battleborn) battery. I also have a 110V Multiplus on the same battery. Both appear to be functioning fine, but I'm only running the Multi in Inverter mode and only charging with the 230v Quatro. Is there going to be a conflict if I turn both charger functions on? Or will I damage the inverter/chargers?

Hy all!

I read hundreds of pages, but it seems i haven't found the right answer.

I have a 3 Phase MultiPlusII 48 3000 35 System, with AC Couppled 5kW Inverter, an DC couppled MPPT and a DIY 48 V 260 Ah Battery Bank with active BMS.

[image]

-- this picture shows the system with battery Cut Off...,

My Problem is, that the Active BMS has no interface to any System, so I used an RaspberryPi, read the "Console" and write to the Colour Control GX via Modbus some data like SOC.

I even tell the MPPT and the PV inverter to stop Charging, when the System is in Island mode (ModbusTCP).

BUT.. when the Grid is connected, I can not tell the MultiPlus to use all available Energy to feed back to grid until the BMS shuts the Relay off itself ...

I am able to stop Charging the battery, but then the Multi does not use any power from the Battery ???? and I can tell the MPPT to stop working (all done via ModbusTCP)

My question is:

Can I stop Bulk and floatcharging via ModbusTCP? or do I have to make different settings?

The System knows the SOC, and i do not need any constant current. and so on.

Important: there is an active BMS. it shuts it's relay off when 100% is reached. no overshooting, no burning energy..

What I want is, that

when charging, and the soc is > 95 % the Charging Power to the battery should be reduced to 0 when 100 % is reached.

all access Power should go back to the grid.

when there is no grid, the Chargers should reduce themselves to 0

Please give me some Info / help

I have a Lithium NMC chemistry battery which is typically considered "full" at 4.2v/cell, I've configured my charging settings so that is goes into absorption at around 4.15v/cell, which is maybe a tad more than 90% full. Right now, I have my BMV set so that it thinks it's full (and I presume then does a sync) at a charged voltage of 4.14/cell (x7= 29v (rounded up)).

Ideally, I would kind of like the BMV to read the realistic SOC, being around 90% at this level, without having to reach the fully charged voltage of 29.4v, which would then mean, as i understand it, that the BMV would never synchronize itself.

Can anyone provide insight as to how I should best set the BMV to accomplish this, or if I even should considering it would never reach 100% soc reading in that case. I am not entirely sure I understand what is accomplished when the BMV performs a "sync", is this something that needs to happen regularly, or as long as the initial calibration is done correctly, will I be okay with a 90% SOC charge ceiling? The BMS modules will not have an issue balancing the cells in this scenario, and have been operating with 4.15v/cell max just fine so far.

Hello All,

I am confirming my Solar/Alternator charging setup/sytem before I install this weekend.

I have a stock E-450 Box truck with a 130amp alternator and typical starting battery as my platform.

I am in need of the following from my system.

• Solar to primarily keep my starting battery charged over long periods of time.
• Solar to charge auxilliary batteries during the day after primary battery has sufficient voltage

Auxilliary Batteries have the following function requirements.

• Power interior box lighting.
• Power exterior box lighting.
• Power for inverter that will handle various electronics.
• Must be recharged during the day after starting battery is sufficiently charged.

My proposed setup is as follows

To connect both the input from the 200 Watt Solar Panels and the 130amp Alternator to the input on a 200-2 Argofet Battery Isolator to primarily charge the Output 1 Starting Battery, and to isolate that battery from the auxiliary battery bank (output 2) until it has achieved the desired voltage. The battery bank will be connected to a BP100 to limit its voltage drop so as to keep the auxiliary batteries from outputting voltage to an unrecoverable state. The BP 100 would be wired to an auxiliary fuse block from the auxiliary battery bank to output to the various lighting, inverters and others accessories.

This design would hopefully charge the batteries with both DC sources (even simultaneously with car running and panels charging) charging the batterie/s.

If I am totally incorrect about this basic design, please let me know where I have goofed!

I have searched for this setup but could find no real information!

Thank you in advance!

I am installing a Multiplus Compact 2000 into a 50 A Airstream travel trailer. I plan to disconnect L1 from the AC circuit panel, run it to the Multiplus, then re-feed the 50 A breaker for that half of the panel with the output of the Multiplus. Here is a diagram of what I want to do.

Is there any problem in jumpering the neutrals like this? The manual shows them separate, but I can't think of a reason it would matter in an RV setup.

Thanks

I have a bank of Rolls AGM 115ah batteries wired in 3 pairs to give 345ah at 24 volt.

These are connected to a Quattro 24/3000/70 inverter and a 100/30 Victron MPPT smart controller via a Victron datalink box

These communicate to a CCGX color controller.

I just added a smart BMV 702 battery monitor and powered everything up.

The CCGX does see the Solar MPPT and BMV but now does not see the Quattro.

Using ve-config I can see the inverter is OK, has the latest firmware, and reports an SOC of 100% (which ties in with the BMV). Whilst connected to the CCGX and the inverter is off the inverter starts when running ve-config then stays running when disconnected from the PC but is still missing from the CCGX list of devices

I am at a loss as to why the color control does not see the inverter despite changing cables and re flashing the inverter firmware with latest version

Any help would be appreciated please!

Any advice for charger setup?

I am re-configuring my 4x220ah 24v battery bank powered by a Victron Multiplus 3000w inverter, solar panels and alternator to conform to the Victron recommended balanced set up using appropriate busbars..

Given this configuration, I would like some recommendations on power cable sizing.

Parallel cables 12v to 24v 80 cm length

Series from 220ah to 440ah .90 cm length

Busbar to battery Positive and negative cables 125 cm length

It appears that I am in the neighborhood of a 35mm2 or 50mm2 size. Is it wise to err to the 50mm size of is 35mm good.

Also, is it best to have a consistent length for the busbar to battery cables?

Thanks

Is it possible to add a bluetooth dongle to a Skylla IP44 charger to be able to add it into the Victron connect app?

I installed the BMV-712 and it worked perfectly for two day while not using the Bluetooth feature. On day three I downloaded and installed the Victron Connect App on my Samsung S7. When I opened the app for the first time, it connected to the BMV-712 and informed me the BMV-712 needed to be updated. I agreed and the process began.

The installation got to 4-6%, then restarted, Next time it got to approximately 11% then restarted. This happened several more times, with the highest percentage being around 80%. Unfortunately, it eventually failed. I then looked at the BMV-712 display, and it read "bt200".

I then tried the following:

1. Try #1

a. Uninstalled Victron Connect App from Samsung S7

b. Reinstalled Victron Connect App onto Samsung S7

c. Connected to BMV-712, but no info on Victron Connect App or on BMV-712 (i.e. still read "bt200")

2. Try #2

a. Uninstalled Victron Connect App from Samsung S7

b. Delete bluetooth data and cache from Samsung S7

c. Reinstalled Victron Connect App onto Samsung S7

d. Connected to BMV-712, but no info on Victron Connect App or on BMV-712 (i.e. still read "bt200")

3. Try #3 ... repeated Try #2 (after unplugging BMV-712 for 10 minutes)

4. Try #4

a. Turned off Bluetooth on Samsung S7

b. Installed Victron Connect App onto Apple iPad

c. Connected to BMV-712, but no info on Victron Connect App or on BMV-712 (i.e. still read "bt200")

5. Try #5

a. Uninstalled Victron Connect App from Apple iPad

b. Reinstalled Victron Connect App onto Apple iPad

c. Connected to BMV-712, but no info on Victron Connect App or on BMV-712 (i.e. still read "bt200")

6. Try #6 ... repeated Try #5 (after unplugging BMV-712 cable for 10 minutes)

7. Try #7 ... repeated Try #5 (after unplugging BMV-712 cable for 10 minutes AND resetting BMV-712 -- "Setup + Select" for 3 seconds)

8. Try #8

a. Turned off bluetooth on Apple iPad

b. Installed Victron Connect App on Macbook Pro

c. Connected to BMV-712, but no info on Victron Connect App or on BMV-712 (i.e. still read "bt200")

9. Try #9 ... repeated Try #8 (after unplugging BMV-712 cable for 10 minutes AND resetting BMV-712 -- "Setup + Select" for 3 seconds)

All attempts were within 2 feet of the BMV-712. I have wasted a lot of time trying to get this to work. I have no more ideas. Please help.

I have the Service Report files from all three methods (Samsung S7, Apple iPad, and Apple Macbook Pro) if needed.

Hi.

Have just had a Multiplus 12/3000/50/ 240 volt inverter installed in our van.

Supplies power on output 1 both on and off grid.

No voltage on output 2, whether connected to the grid or not.

Is there a configuration issue

Hi

Will this software upgrade allow the multiplus 12/1600 compact to be switched on/off using the Bluetooth dongle when using victor batteries with a BMS.

Many thanks

My Blue Smart IP22 charger (12 V / 30 A - 3 outputs) sometimes trips the automatic fuse of the shore supply when starting up. The fuse is 10 A , B-curve type. No other equipment than the charger is connected at that moment so the charger must be the cause of this. When the charger does not trip the fuse, it functions normally.
What could be the cause ? Is this a known issue ? Any suggestions for a solution ?

Color Controller only show blue screen with logo and name (Victron)

Did an update according to manual. with micro sg card. firmware show 2.18 of color controller.

Load new firmware ver 2.33 on micro. the file then update to a point and the stop.

Did again ver 2.18,.

Connect and set up all equipment. BM Inverter LiFe batt and color controller.

Then the color controller reboot and only stop again on blue screen and logo.

Hi,

My BlueSolar MPPT 75/50 (v1.12) has been working for many years, I recently connect to my laptop and VictronConnect, it detected a new firmware v1.39 and I have to upgrade to continue using VictronConnect.

I upgraded the firmware but now charging staoped and there is a error on Victron software "#116 Lost Calibration Data" its not working anymore. Bulk and Absorption LED flashing blue simultaniously.

I down loaded v1.43, upgraded but still same issue.

Can anyone help revert back to the original firmware v1.12 please, my device is 6 years old so cant send back to dealer.

Any help will be appreciatded.

does the victron 702 measure the % of , house, starter, or both ? also I have a new renogy solar controller and the two %od batteries, don't jive, the renogy solar panels controller only goes to the house side while the victron is wired to house and starter

Why is the earth leakage breaker installed downstream of Output 1 tripping.

Have installed the Multiplus inverter in our van.

Connected GPO’s to output 1.

Installed an earth leakage breaker downstream.

It trips as soon as the inverter is switched on.

Is it because the inverter has the neutral and earth connected?

Taking the ELCB out of the downstream circuit and it operates as expected

Except now no power from Output 2

Hi

I have a 2 week old installation of OzPv gel batteries charged by a Victron MPPT 250/100, a Multiplus 5000Va inverter and ColourGX. I get no battery SOC even tho the MPPT knows when to move to absorb'float etc during daytime and the Multiplus knows how much charge taken from the batteries. Is there a setting for CGX to display SOC or do I need more hardware?

Thanks. You guys do a great job!

I have a 12v lead acid battery that I drained to 50% SOC but when the charge controller starts charging the battery it will increase the SOC normally until the charger makes the battery reach 13.20v while current is going into it, which makes the SOC jump to 100%. I know the battery isn't 100% SOC because its still undergoing the bulk charge and hasn't touched absorption/float as it normally does.

I assumed since the BMV does calculations with amperage for discharging to determine that actual SOC instead of relying on voltage, that it would do the same with charging.

Also I could have the BMV configured incorrectly so if there is something I should change in the settings let me know.

I have a multiplus 5000 and 2 LiFePo4 batteries. I am currently charging them with solar power.

I am thinking of bying 2 more batteries. Is it possible to connect a generator to the multiplus to charge the batteries, and only charge the batteries. I don’t want the generator to supply the loads, only charge.

Blink at Bulk mode but charging
