Any advice for charger setup?

Ich habe 2 unabhängige Systeme (MPPT-Regler 75/10, 90 bzw. 100Ah-Batterien), die ich abwechselnd mit einem SolarSwiss Faltpanel lade (ein System im Wohnwagen, eines im Garten). Als ich vorgestern das Panel -am Wohnwagen ansteckte und mit der Connect-App kontrollierte, verlangte die App ein Firmware-Update. Nach dem Update verband sich die App wieder mit dem Regler. die Anzeige des Solarstroms war 0 Watt, 0,1 Volt. Offensichtlich lud das Panel nicht.

Ich habe dann heute im Garten das Panel an das unabhängige System angesteckt. Hier das gleiche Spiel: Firmware-Update, dann erneute Verbindung und keine Ladung (0 Watt, 0,1 Volt auch hier die Anzeige in der App).

Das Panel habe ich gemessen, bringt rund 20 Volt und zwischen 3 und 3,3 Ampere.

Hat jemand eine Idee, an was das liegen könnte? es wäre schon seltsamer Zufall, wenn beide Regler zeitgleich einfach so kaputt gingen, oder?

Ich danke schon jetzt für Eure Gedanken.

Herzlichst

We currently have a Mastervolt IVET 4.5 iso transformer on our boat, but Mastervolt no longer makes them. We would like to switch to Victron due to great quality build and customer support as well as cost. But the 3600 Isolation Transformer isn't strong enough and the 7000 only works with 220 in/out. Since we want to have AC on the boat, I can't imagine I'm the first one to run into this. Is it possible to run two 3600's in series? It would get us up to 7200 volts and 64 amps at 115v which would be ideal. Fortunately, the original builder of the boat wired her for just about anything you could imagine, so no issues there. I just can't seem to find anything that addresses this.

This is a drawing of my "powerplant". Except for the part with the Ouattro Inverters, I have already realized everything:

[image]

Black normal operation:

In normal operation, the solar system feeds the battery charger and the battery is charged.
At night, the battery is discharged via the same path.
PV and battery can be switched off by NA if malfunctioning.


Red are the actions in case of power failure:

The network is disconnected by a large contactor. (How to do that exactly, I have to find out)
Due to the power failure, the two contactors open from the NA protection
The voltage or current on the supply line of the NA protection breaks down.
The battery WR registers this and activates DC out and the power reduction of the PV to 1/3 power = 27.6 kW
The NA protection registers a correct voltage / frequency and opens the contactors for the PV system
The PV system starts up again and supplies power to the battery and house

Everything seems correct, but is that correct under VDE AR4105?

What is missing, what else needs to be considered?
Please your comments!

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

Brand new Victron Multi plus Charger/Inverter 16A . When +12v cable applied "Low voltage lt " comes on and stays on irrespective of programming. Battery voltage : 12.5 v. The unit does not charge and when Inverter is selected it does not invert . Depowering and reprogramming dip switches has been tried several times . Some "clicking" can be heard in the unit when main switch is changed over- Off-Inverter- Charging .

Hi, we have a lithium battery pack that we would like to fit to a vehicle and log, we want to record the charge to the battery, the current drawn from the battery and the vehicle alternator, and we need at least 1 second logging intervals.

The question is, is it possible to have all 3 BMV battery monitors logging to one laptop, and will the data be synchronized, so that we can compare values easily?

thanks

mike

I have a complete Victron battery monitoring/charging system on a sailing vessel. This all works great. One of the key reasons I standardised on Victron, was the logging ability of the CCGX; it far exceeded any other product. Especially the ability to perform offline logging for months, and then upload later to the VRM portal (which itself is really good for analysis).

I have a number of other voltages and currents that I would also like to log in the same fashion. I do that now with independent units from Madgetech. However, it would be much better to consolidate all those data points in the CCGX logging.

I know I can hook up to five BMV units to the CCGX, and those will all be logged. But they are real overkill, both from a cost perspective, panel real estate, and potential user confusion in the CCGX interface.

Are there any other options available that exist, or mechanisms that people have come up with?

Thanks,

Allan.

Hello,

Could Victron relatively easily add wind modes for the current crop of MPPT smart controllers?

As companies like Midnite Solar have added useful wind and water modes to their regular solar controllers, I was wondering if Victron might consider doing the same in the near future?

I would assume I am not going to get any clear answers on this, but have been building a regular solar system with Victron mppt controllers and VRM and am very happy with it.
In adding a wind turbine the obvious path would be something that ties into the same system flawlessly. Grateful for any hints ;)

Hi folks!

In the southern french Alps (not at sea!) my 30kWh batteries are fed with a MPPT 150/65, managed with a BMV 712 and used by a multiplus24/5000/230 all installed 2 week ago.

How do I force an equalization after topping the electrolite with distilled water?

thanks

Lionel

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

Hello

We have 3 Quattro 10000kva setup in 3 phase.

20 lifepo4 100 Ah victron batteries setup as 51.2v 500ah

Batteries are charged with mppt 150/70 blues olar cc

The system keeps shutting down for a spilt second at a time in the mornings. It happens at least once or twice sometimes more. How can we rectify this?

Regards

Hi,

I,m searching for a way to control devices onboard which are connected to the 220V system.

I would like to turn on the heat in the boat an perhaps be able to start the fridge in the boat so the fridge is already cold when we arrive at the boat. Is that doable with the Venus or the CCGX ?

Or is there another way to do that perhaps ? I would like to control 2 or 3 devices on 220V.

I have a small setup with a Blue Solar Smart MPPT 100/20 on a 12V Lithium Ion 100Ah. I am upgrading to to 24V 100Ah and adding Battery Protect and a BMV712. My question is; do I have to do a factory reset before I connect to the new higher voltage (24V) ? as I do not want to blow the MPPT controller.

Also do I need to clear the history?

Good Day

I have a PYLONTECH 8kw 48V battery setup with a Victron Multiplus on ESS, connected to Solar.

One issue I have is that when the mains supply fails and am running on batteries at night, I cannot limit the level of discharge (batteries discharge below 80%).

I tried adjusting the dc input low shutdown on the Multiplus but did not work.

Please advise. I would to limit the battery to lowest 85% discharge level.

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 ?

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

Regards Richard.

3kVA Multi; Venus GX; 3 x 2.4kWh PylonTech's and 3.96kW PV in ESS mode with feed-in allowed and 'Keep batteries charged'. DVCC on as should be, 2.31 Venus firmware and all other firmware no later than 3 months. Battery voltage rapidly drops to below 50V and SOC progressively during night from 99% to 94% in early morning just before sunrise. Is this normal? If not, how do I correct?

After last update there is a third service from the BMV 712 in ve.smartnetwork.

Do Any of you have an explanation for this?

VictronConnect v5.8

BMV 712 v4.01

[image]

Is it possible to connect more than one device to the Load or Charge Disconnect port on the VE Bus BMS? I need the BMS to charge disconnect both the MPPT and the Cyrix Li-ct, whch both have a remote on/of port.

Anyone else using a Tesla battery? I'm surprised to find that I can not turn on my inverter below 21.8V. Do I have to return this inverter?

The tesla battery is supposed to be 20% SOC at 19V, 100% SOC at 25V. Please help me utilize my full battery. Thanks.

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 BMV-600S installed in my van and a VE-Direct to USB interface cable (ASS030530010) but the plug does not match the pins in the monitor. Is it possible to use this interface cable with the 600S and can anyone give me the pinout connections.

thanks

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

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, in the case of comms failure between master and inverter, is the Fronius inverter automatically disabled or kept with the last known setpoints?

Thanks

I have bmv-712, color control GX, SmartSolar MPPT 150/100 and 12/3000 inverter charger. They've been working fine for nearly 3 months. This morning the BMV and solar updated when I fired up Victron Connect. I also looked and the CCGX updated a few days ago. Now I cannot open the remote console from victron connect app. I can access it through VRM - its reporting. The panel itself seems to work fine. I've checked networking and rebooted everything.

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?
