config

red light low battery always on.

battery pack 13s3p of yuasa lev50n (max volt 4.1 and min volt 2,75 - 50 A)

REC Q BMS

min volt pack 2.75x13 =35,75 V

max volt pack 4.1x13=53.3 V

when not enough photovoltaic never works battery only the external grid as backup

ESS installed and all firmware ok

some help in ESS configuration

I have a MultiPlus 12/3000/120/16 connected to my batteries and also a BlueSolar MPPT 100/50.

Is it possible to configure the MultiPlus so that it will prefer the sun to charge the batteries, and if the sun isn't strong enough, it will be supplemented with shore power?

The Victron Connect App is reporting the voltage on my battery as approximately 1 (one) volt higher than it really is. By "really is", I mean that I am witnessing the battery voltage, firstly on the in-built voltmeter on the Motor Home control unit and again (using a good quality) voltmeter at the "BAT+ & BAT-" terminal of the 75/10.

The image below, hopefully shows my test layout. There is also a video.

My assumption is, that if the 75/10 is "miss-informed" on the actual battery voltage, all management functions are probably in error too? For example, when the 75/10 thinks that my battery is at 14.2v - it is not! It is only at 13.2v etc.

How can this be corrected?

Best regards, Martin

Good day. I am a bit confused with "how to" set / Program the easysolar 1600/24.

I have installed:

- Easysolar 24/1600

- BMV700

- Color control

i have purchased VE Direct to USB interface cable , Interface MK3 - USB (VEBus to USB) ,VE Direct cable.bluetooth dongle...

Where I need help :

1- I have connected the BMV 700 to the shunt and have all readings on the BMV 700.

2- I am having difficulties connecting the color control. I am a bit confused as to which ports must be connected.

- On the EasySolar, I clearly see the VE Direct port of the charge controler, but I do not see any port on the inverter part ; So I wonder how to connect ( to program) the inverter part of the easysolar to the color control.

Could someone help me by telling me which cables do I need to do this configuration, and where to connect them ? i have been looking for videos and tutos but can't find any .

Greatly appreciate your help.

Thanks

According to this video from Victron is should be possible to see Venus GX in the VictronConnect App.

Sad enough I can't seem to find my Venus GX.

It's online and working... WiFi is active...

Is there something in the Venus OS I need to enable?

Bonjour,

J'ai un régulateur victron mppt 100/20, un convertisseur victron 12/375va. Je souhaiterais utiliser la sortie de charge de mon régulateur en tant que sécurité basse tension pour mon convertisseur.

De ce que je me suis renseigné, je retiens que je dois laisser le shunt sur la prise "remote" de mon convertisseur et rajouter un fil qui part de la borne de gauche de ce shunt et le raccorder à la borne + de la sortie load de mon régulateur. Vrai ?

Merci par avance.

Hi from a longtime Victron reseller in Colorado. I have a solar home sales opportunity where there are no code inspections--hence little worry that Quattro has no American style UL1741 label.

AC coupling or DC coupling is still undecided but either way I need approval to "sell" excess energy into the "mains". Lawfully grid-tied Victron may be a first for this side of the pond.

The public power company wants compliance with "IEEE Standard 1547 Guide for Distributed Generation Interconnection". Here's a link:

https://standards.ieee.org/standard/1547-2018.html

but is that equivalent to any of these grid code standards in VEConfig3?

The mains engineers are more likely to approve the intertie if I can document Victron compliance with IEEE1547.

How about that Victron Energy Staff? Any thoughts or help? Thanks in advance~

Is the consumption shown on the dashboard the total consumption or does it exclude those circuit breakers not backed-up?

I can't get CCGX to turn on. Help!

Situation

1: CCGX is powered from the positive and negative bus bars (confirmed power to end of cable). Red on top and black on bottom.

2: CCGX connected to Multiplus via UTP cable.

3: No power (i.e. CCGX screen is blank).

Remedy steps tried:

1. Unplugged power from CCGX and verified with multimeter.

2. Unplugged UTP cable from both CCGX and Multiplus, then plugged back into both.

3. Reset CCGX (Buttons E + A + B)

Note: CCGX has firmware version 2.04 out of the box. I have not updated.

Will Load output on SmartSolar MPPT 100/20 cut of on the positive (plus) side and the negative (minus) is unaffected or how is it works?

Can I ask if mixing different components from differing manufacturers is ok? For example I have a Stirling B2B charger, a victron inverter/charger, an Epever MPPT and a couple of Valence lithium batteries. Sorry if I sound a bit naive- I'm new on configuring things out!

Cheers

Hi all,

I understand you can build a multiphase system by using multiple devices, and also you can increase available power by parallelling multiple devices. I also understand the models and firmware used need to be the same.

Is it a requirement that all phases in a multiphase system have the same amount of devices in parallel?

Just clarify the question: Is it possible/desirable/supported to build a multiphase system where power for L2 and L3 are provided by a single device, and L1 has 2 devices parallelled because this phase has a higher power requirement?

Thanks in advance!

Best regards,

Johan.

Hi.

Using a Colour Control GX and Quattro on a marine vessel.

I’ve a generator connected to the AC1 input and shore power routed to AC2.

Is there a way to Rename the tiles / icons in the Colour control GX panel ?

The main thing that’s bugging me currently is that AC1 shows as Grid - Ideally I would like AC1 to show the name Generator, and AC2 to show Shore Power.

Any suggestions would be great.

Best Regards

The battery configuration in my Navion is different than that of the instructions. My system is setup so that negative terminals are connected together and positive terminals are connected together and what appears to be another shunt as well. I can see the load is coming off one of the negative terminals on the right side of the picture. Under this type of configuration what do I do? Any help would be greatly appreciated. The unit has a generator, shore power connection and solar. In addition, there is a bypass to "jump" the engine if the chassis battery were to die.

Hi,

I have a SmartSolar MPPT 75/10 that I’m using to control supplemental lighting in our chicken coop. (Chickens need 13-14 hours of light a day to trigger egg production.)

The SmartSolar controller is the best option out there but it would be perfect if I could have it turn on the load 14 hours *before* sunset and off at Sunrise.

Anyone know of a way to trick it into doing this? As far as I can tell, I’m going to have to manually adjust the timing every week throughout the year.

thanks,

Brian

Our 5 Blue Solar MPPTs are connected to a Venus GX by VE Direct cables. To configure them I need to physically disconnect VE Direct cables from the Venus (not at all easy on a boat) and temporarily connect to a PC/Android running VE Configure app.

Am I missing something? There must be an easier way!??

Hello

I have bought myself 7200Wp of solar panels. 24 x 300wp facing a bit of south. Incline on the roof at 50degrees.

I also have an 40kWh lithium battery. 50V min 60V max. Max charge and discharge power is 9kW. Max discharge of 18kW for 2hours. The battery will be expand every year until the first place is filled and then I have 100kWh. There is already started on making place for an second battery of another 100kWh. But that is a bit dreamy.

Now the goal is that I put the entire house offgrid, but have the grid as backup and pull in when the battery is flat. I may not feed back to the grid. In summer I think, depending on how much electric distance we drive, we can make it 4 months completely offgrid. In Winter the house will be almost offgrid and the cars will be charging most of the time at night from the grid. Offpeak time electricity is 12% cheaper.

We have a plug in hybrid. Charging is 10kWh in 3 hours or 11kWh in 8 hours. +200kWh a month. And a full EV. Charging every day 10-15KWh in 3-5 hours. +300kWh a month. Sometimes we need fast charging in between runs and then I want to be able to charge 3 phase 16A =11kW, this may be grid charging. The car can handle up to 22kW 3 phase 32A but my grid connection is only 3 phase 25A.

So the configuration needs to be a 3fase configuration with a power output of + 15KW.

What gear do I need?

Thanks in advance

Hi is it possible to run 1 Multiplus 48/3000/35 and 2 x Phoenix 48/3000 inverters in Parallel? where the Multiplus and a SmartSolar MPPT 250/100 is used to charge the battery bank and the Multiplus and Phoenix inverters supply the peak AC loads.

Thanks,

Jannie

We are currently working on research of PV-based microgrids energy management algorithms. Our facilities include a microgrid with PV panels, PV, grid, wind and and load emulators, batteries (mostly lead-acid) as well as two bidirectional converters with poor user-based external controllability.

We had a look on Victron products to evaluate the possibility to purchase one bidirectional converter depending on their external controllability. In the following we include the grid architecture we are working on as well as a short list of the variables we want to measure/control.

The AC microgrid is composed by two groups of PV generators, the connection to the Utility Grid, an Energy Storage System (composed of a Bidirectional Converter and a Battery Bank) and two types of load demands (Critical and Non-Critical: CL and NCL). PV field 1 with the Utility Grid and the Non-critical loads are connected to the AC input of the Bidirectional Converter and the PV field 2 with the Critical loads are connected to the Bidirectional Converter AC output.

[image]

An external Energy Management System should be able to read and write registers in the Bidirectional converter.

WRITE:

. Power exchange between the Bidirectional converter and the Utility Grid through the AC in port (PBC_ACin)

. Battery Bank absorption time

. Change/discharge or Charge ONLY mode

READ:

. Battery SOC

. Absorption charge flag

All these settings should be modified using a suitable communication protocol via the bidirectional inverter serial port facility.

Is there any Victron bidirectional converter fitting these requirements?
