Help

Screen shows 96% 12.9 v when going to bed but then in the morning they show 96% 10.4v and alarm warning sets off - when I switch it off and then back on again it goes back to 96% 12.9v can’t understand why this is happening all new batteries and equipment

I have a Quattro 24v 8000 as part of a 4kw off grid solar system with 1000ah traction batteries (12 x 2v in series) . I have a Hyundai DHY8000SELR generator (apparently 7.2 kva) wired into the AC1 of the quattro. I have set the input voltage to a maximum of 16a as my generator seems to trip out if its set above this (which is annoying as it should be able to provide 30a, but this is a separate problem).

The issue is that the quattro is switching to charging (bulk) and mains staying in this mode for a couple of minutes then switching back to inverter mode for about 20 - 30 seconds then back into charge mode. Is there a reason for this? have I got the settings wrong?

Any help/suggestions would be really gratefully received!

I've also set with the dip switches the charge current limitation to 75%

so the dip switches are as follows:

8= off

7= on

6= on

5= off

4= on

3= off

2= off

1= off

75/15 controller, fitted in a campervan approx 2 weeks. 100w solar panel is clipped to the roof & connected to controller when needed.

Lastnight on a campsite with electric hookup (2nd time since installation), so solar NOT connected, & 240v charger connected directly to battery.

Anything connected to the 75/15 "load" is pulsing on/off...2seconds off, 4seconds on.

Load is connected (via 6-way fusebox) : phone-chargers, gps-tracker, CB radio...nothing high-power.

The blue LED "Bulk" is flashing about every 3s.

Any ideas?

EDIT:

Hardware firmware:v1.39

Interface V2, firmware:V2.19

Bootloader: V1.10

I recently updated my travel trailers power system. I installed 4 100w solar panels wired in series. Those run down to a Victron 100/30 charge controller and Victron Battery monitor. They are connected to a Battle Born 100w Lithium battery and a Victron Multiplus 12/3000w inverter which is tied into the circuit breaker.

My problem is a constant 6-6.3 amp draw on the system. I have no idea where it is coming from. I have tried shutting down all circut breakers and fuses and it dosent stop the draw. If I disconnect the battery disconnect between the batter and inverter the power loss stops. Any ideas about where a 6 amp power loss could be coming from?

In Belgium we still have an electrical grid monophase (only 2 cables coming in) without neutral. I think Norway uses this system too.

It is originating from 3 phase 3 x 230V Delta configuration, from which L1 and L2 are coming to the my meterbox. I imagine my neighbours will be on L2-L3 and L1-L3 to divide the grid load.

there is NO neutral wire.

Which Victron system could be used to provide ESS functionallity? I already have a grid-tied solarinstallation, and would like to expand with ESS capabilities.

all help is greatly appriciated

best regards

On dealer advice, bought a phoenix 12/1200 solely to run a fridge freezer in our house. It worked fine for almost 18 months, then developed a buzzing sound & intermitted red alarm fault. We sent it to the local accredited engineer who said he hadn't the facility to test it for long, he ran down a battery checking it, couldn't find a fault, tightened a couple of screws and returned it.

Obviously the fault remained. Contacted him again, he said he needed to examine our set up in person (chargeable) and didn't like the idea that we have a completely separate 12v lighting system, he thinks all should run through inverter which sounds like a poor solar engineer to me as well as irrelevant.

Contacted victron, they say send back to this man who can't test it & is more interested in checking the system. Victron and the engineer have been sent videos of the fault in action, both in and out of the system. Happy to post here if necessary.

The inverter does not function, horrible buzzing sound, red alarm fault. Does this with or without load, in our system or running directly off different, unconnected, stand alone battery.

We have played around with the system, connecting different battery banks, different panel sets, different charge controller and different inverter. The only part that fails in every isolation test is the victron inverter.

Now been living without a fridge freezer for a month, no resolution, no offer of warranty help. My husband has now had to travel overseas to work, hoped he'd resolve long before this.

Feeling utterly let down and frustrated not knowing what to do. If anyone knows a trustworthy, competent person I can get this unit to, for proper testing and repair, please let me know.

Wish I'd bought the cotek.

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!

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

I am looking to buy a 2nd hand CGX, but is concerned HW version may have changed to a point where older versions may not be as efficient as the latest. Can someone please shed light on the topic? PN BPP000300100R SN HQ 1435WEHNT which looks quite old. I am unable to find anything in change logs or searches to suggest I may my myself some future trouble.

Is there any other way I can monitor my battery system without being connected via the internet the installer changed my blue tooth dongles to a Venus gx when changing my old batteries to lithium batteries. I don’t want this solar system using my internet connection.

this morning I woke up to a huge number of alarms from my VRM, basically because the system has been discharging for the last 7 days... from Jul 1 and batteries were at 0% !!!!

Id not really been monitoring actively, as at this time of year in southern spain - we get loads of sun, so charge is not an issue (though im confused why Ive not been getting alarms prior (say at 50%)

when Iook at the VRM, a few things look odd...

https://vrm.victronenergy.com/installation/1701/share/a6e5e9e3

prior to 1st july all seemed ok, it was regularly going between 90%-100 doing bulk, abs , float

but after july 1, on july 2 it started keeping the battery % dramatically, and then each day, would only go up a bit... then stop rising, despite solar pv being available... and never got into abs

in fact if I look on the 30 day overview, you can see that except for yesterday, we still were producing the same amount of solar... but the batteries appear to be (largely) failing to charge....

Id be grateful if someone could have a look at the above installation graphs (last 30 day overview and you'll see my issue) - and advise me what to take a look at....

Im really confused.. nothing has changed...

the only thing I noticed is that there was also (coincidentally?) firmware update on 1st July, which is when the problems started!

is it that the batteries having stopped taking the charge for some reason?

would this be the MPPT?

could it be the BMV-702, just acting up an reporting wrong voltages?

what can i check?

for now, Ive put the generator on, even though we have a lot of PV, as an 'emergency' to see if I can get some charge into the batteries, as obviously running this low is very bad....

(of course its sunday, so can't do much today - and not even sure who to call tommorow :( )

any thoughts

Travelling on canals

Hi again,

sorry for asking so many question in the last couple of days...I find it kind of hard to find information sometimes, seams like information is spread out on to many places and there is some stuffs that are left unknown..

so today, i notice the yellow led is flashing every 3 seconds, in the manual there is no information about that, there is 2 condition where the yellow light flash would indicate a fault but it would have to have the green or the blue led flashing too. no condition with only the yellow light flashing....

FW is v1.39

status on the MPPT is
absorption mode at 14,8v @ 6A

Pv roughly 33v @2.8A

temp is 24C
was in bulk for 4 hrs this morning now in absorption for 45 minutes

I was reading paper version manual for my BMV today, just to review my setting and try to learn more about it. But I got confuse cause I think there is contradicting information within. I had to go check the online version, to check if it was a typo that was maybe corrected. But I find the same error (!?) in the online version of the manual.

I'm saying this, but I might be wrong and confuse, please correct me if I'm wrong. I would really like to know which info is right or if the 2 info I think are contradicting are just 2 different info that I think should be the same..

so at 2.3 commons problems it is mentioned:

[image]

and when reading further, at 4.2.1 Battery settings under 02. Charged Voltage we found that:

[image]

and then if you just the mentioned section 3.7 (in blue ^) the mentioned voltage (13.2v) is proper for float and not for absorb, so think section 2.3 is wrong, unless I am just really confused and those 2 pieces of information are not related to each other...

so to add to my confusion, when I look at my own setup in the BMV, charged voltage is set to 14,8V, which I don't remember having set that, but I would really like to know if this is right or not

If ever i am proven to be wrong, i would like excuse myself in advance since english is not my first language

I'm in a jam and need to get my Multiplus charging my new lithium batteries ASAP. Solar panels not installed yet. Just got everything tested and working and connected batteries only to find out dealer did not inude the MK2-USB cable. I thought I could setup Multiplus va Color GX Controller / monitor or through the wifi dongle they sold me. Appears I can't, I have a USB to ethernet adapter my laptop. Is there anyway to hack or get this to work without the MK-2 USB cable. Need to get this going tonight (eastern U.S. time zone.) Thanks in advance.... MY main issue is to set the charging paramaters till I receive the cable which can't come soon enough. I also have some Raspberry PI 3 and 3+ if that will help.

How is the history feature really working? Does the smartsolar 75/15 has a built in clock, or is it the app keping track of the history? I think I red somewhere the controller itself has no built-in clock. Do l have to start the controller (smartsolar 75/15) at midnight for it to keep track of when one day starts and ends?

when looking at my history in my SmartSolar MPPT 100/20:

[image]

I see that 4 days ago, under "Consump.", it states 20Wh, what does that mean?

that day was the first day of my installation and i had no load connected to it, so it can't be my power usage for that day, furthermore the days i had my refrigerator, inverter and some light connected to my system correspond to "yesterday" and "2 days ago" and there is no value for "Consump." on those day.

so my question is: what is the line "Consump." used for?

Hi all.

FYI, I'm an IT guy and an electronics noob, so please be kind. ;)

I've had my Smart Solar 75/10 since 2nd March this year, and it has been great! However, a few days ago, the battery ran completely flat as the battery had not been charged. At the time I chalked this up to bad weather, but since then, the sun has come out and the charge current remains at 0 watts, 1 watt or 2 watts.

Here are the facts of my set-up:

• Two 12v panels wired in parallel, one 10W, one 80W.
• Always-on load of a Raspberry Pi, plus weather sensing instruments and WiFi antenna. Usually draws 0.2-0.3A from the controller's load output.
• Two lead-acid batteries in parallel, 12v 12Ah, and 12v 2.3Ah.
• The controller has not been disconnected or powered down since first installation . The RPi had an uptime of over a month when the battery stopped charging.
• When the battery died and the load was shut-off automatically, I kept the load disconnected to allow the battery to recharge over several days. However, the controller only reported a yield of 3-10 watts all day. Compared to my average yield of 80-100 watts all day.

Here is what I've checked so far:

• Both solar panels are working fine and gave a 20v output under moderate sunlight for the UK.
• I connected the batteries directly to the solar panels with my multimeter in-line. It showed a draw of 3-4 Amps. Immediately I heard a hissing sound like gas escaping from the batteries, and I stopped. Am I an idiot for directly connecting the panels and batteries, or does this show the batteries are toasted and the controller is not at fault?
• I both visually inspected and continuity tested the 20A fuse and it is fine.
• I have reset the charge controller to default settings.

Observations of the charge controller when operating:

• Despite only charging the battery with 1-2 watts, the status of the controller shifted from bulk, to absorbtion and then float within a few minutes.
• When set to 'battery equalisation' mode, the charge current rose to what I would normally expect at that time of day, 20-30 watts.

Apologises if this doesn't really make sense. Please feel free to ask any questions.

hello,

i would like to know what is the voltage set in the firmware for the BlueSolar MPPT 100/20

Hi!

Just got my installation done yesterday! Fun to look at and check the statistic on the app :)

My system is 100/20 mppt, 2 x 225 ah 6v, 295w solar panel and bmv712 installed in a sprinter van

Yesterday got the charger to charge and everything looked fine, but this morning I went to work parked the van under the sun, it was in bulk mode at that time. 8 hours later, after work I come back to the van, check the mppt status light it shows it’s in absorption, which I though was normal. Then I check the app and it shows it did went thru the float mode for a part of the day...

So I drive back home, once there it was now in float mode, thought it was weird. Went inside my house get a snack, and now it’s back in bulk mode

Is that normal?

I thought the cycles was to happen one after the other and it was not going to cycles thru them. Maybe I’m confused...

Just to make it clear, I have a 12v refrigerator hooked on the system, duty cycle is about 15minutes and it roughly draw 50w while on

Also I have checked the plates they look clean without sulfatation

Hi

I live in Australia

I have 6 x250w panels VOC 37.2

I have 2x 75/15 charge controllers

I want 2 panels to capture the sunrise (East)

I want 2 panels to capture the miday sun (North)

I want 2 panels to capture sunset (West)

what is the best way to wire this configuration to the charge controllers.

Hi all, my phoenix 12/375 inverter does not show any load information on the dial. What could be wrong?

Hi, I need help...I have 3 Lithium smart batteries 12/300, normally charged with a Quattro 12/5000/220V. For charging in USA I have build in a Skylla IP 44 with is connected with Skylla-remote-on/off-cable with the VE CAN BMS (the red light of the "charge disconnect" pin don't shine; but the Skylla don't work.

If I make a cable between + an - of the remote pins of the skylla an setup the BMS off, the Skylla works fine, and I can switch him on/of with the Skylla I control.

What is the problem, why do the BMS not switch on the Skylla (I tried it also with half-full batteries) ? Best regards, Lars

#1 in my vrm.victronenery portal, under devices I don't see my battery/s (have 2 x Pylontech US2000 plus's) I am using the non Pylontech supplied cable. the Victron is getting comms/data from the batteries.

#2 I have 2 x MPPT 150/35's. I see both, any chance I can modify the label shows to something that I will understand better, ie to which PV array they are connected.

#3 I have 2 temperature sensors shown in devices, from where does this data come from, the batteries, same as #2, can I give it a personal label, assume to figure out which is which, simplest is to shut one battery down and see which temp disappear ?

#4 assume the VE.Bus System is the MultiPlus II, again, any way to give it a personal label.

#5 The CarloGavazzi ET112, I can see data inside the VRM site and in the remote console views, but I don't see a cable plugged into either of the comm ports, huh, how's this possible ?

#6 Under advance I can see many grass that can be selected, can I create some custom groupings, aka I select a name and multiple pre configured graphs get selected and data retrieved/displayd.

#7, I can see via Remote console where to selected mqtt under settings/services, I know the IP of my VenusGX, is there a username/password to select, what's the QoS, whats the next option suddenly shown "NMEA2000" ?

Just bought a mppt 100/20 and was sold the optional display smartsolar meter. It has an plug connection like rs232 or vga style connection. I can see guides for plugging it direct into other mppt controllers. Can i wire it to the 100/20 or have i been miss sold it?

Hi folks!

I've had this 48V system running for 4 months now and it works like a charm. It's beautiful to feel like you don't depend on anyone. But that's not true ;). I would hit the equalize button every month until one day I realized that it was not doing it. My setup is in the title plus 24 panels at 230W each mounted in series and parallel as to achieve 100V~130V @ 5 KWH, DC of course. I've tried different firmware versions for the CCGX and updated all devices from VRM. Called my supplier and they said that: This system comes with equalization off by default and that I needed to buy the bluetooth dongle to do this, otherwise I need to have an external generator ( yuck ), in order to activate the equalization. Keep in mind that the "EasySolar" is worth 3,5K. OK. So I need this done NOW so I buy the bootooth wongle and when I head over to, settings/battery, nothing appears. I've tried with different phones and in some of them it detects the MPPT and CCGX and in others it only detects the CCGX, I don't know if that matters because the newer ohone detects the MPPT. I've worked very hard to make this system a reality in my life and I would greatly appreciate if someone with more knowledge that me could help me with this issue, since we all know that equalization is vital in keeping those babies in good health!

This unit was left in a boat unused for several months ,,before a couple of times it went into bulk on then overload then tripped out , a restart cured it , returning to the boat which has been supported by victron. Solar panels. When the inverter is remote powered up it goes ac1. Then yellow bulk on followed by red overload then drop out , after disconnecting the remote and trying at main switch on unit the same happens it’s dead for power batteries are 28 v all connection bolts checked just won’t start up it’s 3 years old and barely used.
