Hi,
My VRM data displays 20kWh in the middle of the night 00:00, this mess upp the data over time.
Is it possible to edit the data on VRM? This must be wrong, there is nothing displayed in System - PV yield.

Kind Regards

First post - A little guidance please on our design below:

We have 48 PV Panels each has an Enphase 215w micro inverter.

We have a genaration meter as part of our FIT

Our utility provider has installed a smart electricity meter to track half hourly usage

Would the below design work for us?

Our decision to connect the PV to the critical loads output (AC output 2) of the Quattro is to ensure the continuous supply from PV and battery in the event of a grid failure.

1) If we connected the panels to the Critical load, as mentioned in step 1 of the installation guide video at 7 minutes into it (https://www.victronenergy.com/live/ess:quick-installation-guide) - Would this work without the need for the additional ET112 meter?

2) With this setup, would we have use of the CCGX to show system energy flows and be able to control the system via the CCGX?

Thanks

Need help on how to do Zero Current Calibration on my set up:

Manual says that to do a zero current calibration "ensure there really is no current flowing in or out of the battery" and "disconnect the cable between the load and the shunt, then press 'select"'

What do they mean by "the cable between the load and the shunt"? and is that really enough to ensure "zero current flowing in or out of the battery" in the case of my set up?

I have two batteries. One negative cable (the one being fully monitored, call it the "main" battery) goes to the "bottom" of the shunt and the other battery (the one with the voltage only being monitored) goes to the "top" of the shunt. Then a "common" cable goes off the top to the common ground.

I also have solar positive and negative leads going from my solar charge controller directly to the main battery

Finally, I have bilge pump, gasoline fume detector, Victron MTTP 100/15 charge controller and Blue Seas ACR all with positive leads connected to the main battery before the battery selector switch and with their negatives going to the same common ground as the BMV 712

So in order to do a zero current calibration and "ensure there really is no current flowing in or out of the battery" would I

1. Disconnect the solar source (disconnect at solar panel end)

2. Disconnect the "common" negative feed off the "top" of the shunt.

AND

Do I also need to disconnect the charge controller, ACR and fume detector in order to accomplish the zero current calibration?

thanks!

1. Hello everyone,

After installing a 3-phase AC coupled system with 6 quattros an a PV inverter connected to AC out of Quattros, we realised that the Quattros cannot connect to grid (AC in1) when the grid operator swap 2 phases. The problem is that the grid operator often swap phases during maintenance of electrical network, and after which the quattros cannot connect anymore to Grid when energy comes back. Is there anyway to change setting of quattro so that they can still connect to grid even if the operator swap 2 phases?

I'm considering replacing my solar controller (Outback FlexMax + accessories) with a set of two Victron 75/15 and the Color Control GX for monitoring.

I have seen the VRM portal details and docs on the JSON API to get data from the portal, but I need to get data locally via TCP/IP, without relying on an active internet connection. From the documentationI've read it is not very clear if this is possible or not.

What are the possible ways of getting data from the Control GX via the local LAN?

Also, what Victron products do I need to monitor battery input/output? In my current system I use a FlexMax FNDC with several shunts for the different charge sources and between the batteries and load. I'd like remote access (via VRM and on local LAN) to all this data so I can analyze it using customer software.

Thanks!

Just found out that Solar Plants went into liquidation just before Christmas and they are no longer trading.

Im fuming given that they are half way through my installation and I’m currently significantly out of pocket. I believe a company called Climate Save Renewables is taking over the Solar Plants business.

Is anyone else in the same boat or have any information?

Hi, I have an existing grid-tied SMA inverter (SMA 5000TL) and 2 strings of 13 panels for total of 6.5kW. I want to add storage and am considering the QUATTRO with 4 x Pylontech US3000 batteries (@48V nom).

The main aim of the exercise is to be self-sufficient in case of extended/indefinate grid outage. I am no expert, but my reading suggests that the Victron QUATTRO would provide a mini-grid on the AC-OUT-1 and that the SMA solar inverter would run 'normally' on this channel regardless of whether the grid was connected or not.

Assuming that the above is correct, would the SMA inverter connected in this way be a stable and reliable configuration. I ask this because I have read some posts/articles that indicate that there are situations where the inverter may go over-voltage and shutdown the QUATTRO.

Is this a potential problem, and what would be the recommended way to deal with this?

Note, the loads would include 1000W and 1500W pumps (bore pump etc), inverter aircon, fridges and freezers, lighting and misc.

thank you,

Ron

I have an array of 3x150W panels wired in parallel to my MPPT 100/50 controller. On a clear sunny day with no shading and clean panels, I've never seen the controller show more than 200W. What's the best place to begin to troubleshoot?

Hi there, community!

I wanna charge my campers’ leisure batteries both via the alternator (Orion-Tr Smart DC-DC Charger Isolated) and solar (SmartSolar 100 / 20 20A MPPT). Can I use both products simultaneously? Thanks!

my Smartsolar reports daily solar yield in watt hours. My BMV-712 reports Consumed Ah. It Would make sense to me use the same unit. Yes?

Hello,

I have my system running scheduled charging (from grid) starting 8:00am until 10:30am.

I have seen periods where there is more than enough solar availability but it's not being inverted for charging and/or covering consumption:

[image]

as seen directly in the console:

[image]

and also as seen directly from the sky:

[image]

but after a while it goes back to normality and solar becomes main input

[image]

can anyone help to understand the reason this happens? It's very usual and I don't know how to limit it.

Thanks in advance.

I'm still making adjustments, so perhaps something isn't quite right yet. My battery bank is 600Ah of Lithium. My Charged Voltage is set to 14.5; Peukert Exponent is 1.05; Current Threshold is 0.10A; Charge Efficiency Factor 99%.

My 150/100 MPPT indicates a battery bank voltage of 13.7, and remains in bulk charging mode.

My load consists of basically the refrigerator and a little bit of electronic gear. BMV is showing 0Ah consumed, and that +450A or so is being applied to the batteries.

There seems to be a mismatch between voltage and tracked current. Am I misunderstanding something?

I had synchronized the BMV just a couple weeks ago shortly after installing it when I was on shore power. We stayed on shore power until just a couple of days ago. My first run down of the batteries when to 28% a couple night ago. Solar has been doing the over the past couple of days; I would not have thought the BMV synchronization would be lost that fast.

Thoughts on what I should check/adjust next?

Hi All, kind of new to all this I have a mppt 75/10 it used to show the battery state as Float most of the time now it always just says off If I put some load on it the load output state changes. Do I have an issue somewhere battery voltage is 13.02v being charged off a 120w panel. Im just a bit confused as to why it used to always say float now it just says off. Thanks for any advice.

Cheers

Chris.

Wondering if it’s possible to show the solar input as separate to the dc/dc charger input. Unit seems to only show the Nett amps where as my other redarc BMS would show current in current out and solar input. Is there a way to replicate this? A

I have four 12V 140 watt solar panels wired in parallel that have worked for 5+ years on my former Blue Sky controller. I want to switch over to Victron so bought the SmartSolar MPPT 10/50 and move the four wires (two PV and two Battery) from the Blue Sky to the Victron. Everything came up and my VictronConnect app showed the panels charging. After 10 minutes my 50 amp fuse between the Victron the batteries blew. A replacement fuse blew instantly. Perplexed because I did not change any wiring - just moved them over from the old controller to new. I've rechecked my wiring and did not accidentally reverse any.

laying out a system for my van. if i have both of these installed connected to the same lifepo4 battery bank will they interfere with eachother (only could happen when engine running obviously) when both are charging the battery bank? bank is big enough so each charging full would be ok amp-wise.

thanks

I have purchased a victron 24/1200 twice now. The first came with a broken case. I sent it back. I ordered another and it came broken too! The same way. The plastic case screw mounts were broken. The quality control sticker was not signed. Are there second on the market? I paid normal price. Any chance the wo rkings are good on this and just th case is bad? (I have a deadline)

If so, is it ok to go with a 50am even if I will mostly plug into 15amp shore?

(We will have 200ah lithium @24v and 1600w solar)

Multiplus 24/3000 - can I input 50 amp (both legs) and only pass through one leg to a distribution box?

(My goal is to take advantage of the full 50amp for charging but it is unnecessary for Rv loads. We have 4 x 12v 100ah lithium batteries capable of .5 c charge each. They are run in two strings parallel to create 24v 200ah. )

i have color control GX with victron blue solar MPPT, multiplus inverter and BMV702 connected . i am unable to get any solar PV display showing on the LCD color control panel. i have swapped VE direct leads and even tried another blue solar MPPT. the MPPT seems to be working fine and charging the batteries etc ,, but cannot get any connection to the panel. i even spliced back one of the VE direct leads and did a continuity check which all seemed fine, however was surpised to see the +5v power on the BLACK wire and GND on the RED wire, but all the DC polarity is correct at the plugs. Am i missing something in the setup/option perhaps ?? Victron gear is all new to me although i do have electronics understanding so im not a complete newbie. any ideas ?

I am going to connect a pool pump to solar and use AC power as the fall back. What parts do I need for this? The pump is a 3/4 hp.

Defekt?

Hello,

I have a Quattro 24/5000/120 connected to a pair of 12V lithium batteries in series, with a BMV 712 monitoring them.

I also have a backup generator in the system wired to a transfer switch.

I am adding PV panels (and Victron MPPT controllers) to use to both charge the batteries and supply AC loads when able.
ESS seems the only solution that allows this, as without it, my MPPT controllers act primarily as battery chargers and no portion of the solar used for AC loads.

My questions are,

1) Can I please have the grid code password?

2) My installation is in the US. There is no US gridcode option, so I assume I will be using other. Is this correct?

3) In using other as a gridcode, I have no desire to feed any power back to the grid-main. So I intend to set feed-in to disabled and to set LOM to B. Are there additional settings to review?

4) With no Feed-in and LOM to B, that should disable any possibility of sending current back out AC input 1 (grid-mains), correct?

5) My visual indication that LOM was successfully detected is when the CCGX show no mains input. At that point there is no possibility current could exist on AC1 (grid-mains) Is this correct?

Thank you in advance for your help.

I want to run an idea by this group. I have a camper van with 300w of solar on the roof wired in parallel. I can get a deal on the same panels to add two more. With no room on the roof, I was thinking about doing a ground deploy. I was thinking about getting a zamp (SAE) external hookup and place it in the rear next to my AC shore hookup, then run a wire from there up to my roof combiner so I can use the same charge controller (100/50). Do you guys see any problems with doing this? I know adding another controller is the preferred method, but I've got a full electrical compartment and no room to add another controller. The panels will be the same spec so there shouldn't be differences between voltage. The only thing I can think would be an issue would be the voltage drop but with 10awg wire, I don't think that should be an issue with such a short run.

Anyone come across a solar radiation sensor with output voltage proportion to incoming insolation. Would like to record the values with the Venus GX.

Hello,

I'm in the process of upgrading my equipment to Victron but I'm having a few issues with the solar charger voltage.

Currently I have

4x100AH flooded batteries (will be upgraded later)

120w solar panel (will be upgraded later)

Victron 3000w/12/50 inverter

Victron BMV-712 battery monitor

Victron 100/50 Smart solar

On random clear sunny days the solar voltage will drop to 12v but the following day it'll be back up to 21v. It isn't a weather issue nor panel as I've metered the solar voltage from the panel and it registers 21v but when plugged into the solar charger it reports 12v?

Here is photos showing the problem

Any ideas?

I've got a 50/100 charge controller on my camper, 2 100 watt panels, and a single 100ah battleborn battery.

I recently had my camper in to get my radio wired into both the engine battery and camper battery with a switch between. I realized they only hooked it up to the camper battery when the battery completely died. I tried to charge it with my shore power hookup. I think since the battery was dead, something wasnt recognizing a battery being there and it wouldnt charge it.

I then unhooked everything from the battery, and jumped it from the engine battery. hooked everything back up, and was able to charge it through shore power from there, and everything functioned normally.

Im wondering if when hooking everything back up i blew a fuse in the charge controller itself? my other thought was that I might have blown one of the inline fuses coming from the panels, though I've got a 20a fuse between my battery and charge controller, Id be surprised if it was the solar panel inline fuses.

I havent been able to check them because the renogy mounts make it an absolute pain to reach the bolts. Otherwise I'd have to remove the mounts from the roof itself which means a lot of disassembly to access those mount bolts, which i'd really like to avoid.

Does this sound like a problem with the charge controller itself? any other Ideas?

Under “System Status in VRM” in the “Solar Yield” quadrant/box of the dashboard there is a temperature number listed there.

Where is that temp sourced from?

Directly from MPPT controllers? If so, which one if multiple?

Area temperature based on weather reporting and stated location of site in VRM?

Other?

Thanks.

how to get my BMV 700 to show actual low Battery volts instead of 0.000 when I check the history

I have two Quattros, both connected to a DC power bank.

I also have a Bluesolar MPPT 150 l 70 MC4, but this is not installed yet, since I haven't bought any solar panels yet.

Now: how do I control and monitor all of this stuff?
I do have a Raspberry Pi lying around, so the ideal solution would connect this to both Quattros and the MPPT, since I could also use it for a security camera etc.

I did buy the MK3-USB, but I didn’t get it to work with my Mac.

I also have two multi control panels — which to be honest I would rather sell and not use.
