I do experience PHASE ROTATION alarms in a hybrid system with generators, Quattros in 3~ configuration and grid feed inverters SMA STP** after sunrise and before sunset. The generator is not connected during that time. Local / regional VE people are clueless, anybody with similar experiences?

Hello,

Looks like I cannot pair by bluetooth with my MPPT Bluesolar charge controller 150/60 TR.

Configuration : Macbook Pro 15' mid-2012 with Mac OS 10.13.6 (High Sierra) + Bluetooth 6.0
VE-direct bluetooth smart dongle.
I'm in an isolate site (no internet).

Troubleshooting : I checked the troubleshooting section for the last 3 days. I read a lot of threads and questions concerning differents issues the community encountered. But I got no real solution. I unpaired and deleted the VE-direct device on my bluetooth system configuration window before every attempt to connect with VictronConnect, I also cleared the pin code. I ONLY connect bluetooth with VictronConnect which release is up-to-date. No other bluetooth device can cause the issue. I always attempt to connect bluetooth within 30 seconds after pluging the dongle to the MPPT. I also reseted the bluetooth parameters on my computer. Nothing changes.

Issue : The firmware passes correctly. The dongle leds blink like they should. The MPPT led bulk is blinking correctly.
But when I try to pair the VictronConnect app with the dongle, it asks me the usual pin code at 20%, then gets stuck to 80%, then goes back to 20%. And, after what it looks like 4 or 5 attempts, I have an error message (see the pics).
Can you tell me what I did wrong ?

Thank you !

I want to run a fridge from my 12/350 inverter. There's a connection block for switching the inverter on and off, but nothing in the manual about how to use it. Do the terminals need shorting to switch on the inverter or do I need to feed it a voltage?

What I am hoping to do is to attach a thermostat from inside the fridge to the connection block to switch on the inverter as needed. Would this work?

Thanks,

John

Hello,

We are having some trouble getting a Smart Battery Protect module to operate whilst connected to the VE Bus BMS load disconnect when using the non-inverting remote on/off cable. We can get it to work with a direct connection however; is the non-inverting remote on/off cable no longer required for this?

On the BMV (battery monitor) we have a screen with TTG (Time to go), indicating the time the battery will last with the current load (profile). It would be great to have a (customizable) "Time to go" indication on the CCGX overview screen. (And maybe also in VRM.) The feature would be great for situation where you depend on the battery and you have to adjust loads to make it through the night, for example. I have customers that removed their diesel generator and run their house completely with a solar-storage system. It would be very helpful if they have an indication if their battery is going to make it until the next morning and if they then can adjust the loads in their house, if they see that the battery will not make it.

Thanks in advance for considering this!

Hello
I have a smart BMV-712 and a Multiplus24 | 5000 | 120 - 100 | 230 / 240V.
I would like to stop the battery discharge to 40% to 50% maximum.
I would like to use the BMV relay to drive the Multiplus.
It's possible ? and how ?
Thank you

When I leave the boat and the batteries are:

STARTER Batt.=13,0v

HOUSE Batt.=12,5v

after 24h with everything OFF the batteries have both the same voltage (~12.7v).

I thought right away that the Cyrix is connecting both batteries and when I tested with a voltmeter, there is indeed connection from both poles of the Cyrix. Is this a normal behavior?

See video HERE.

My current setup is:

Hi,

I'm busy with an installation where we are installing 3x 8kVa Quattro's as a 3ph system which needs to act as battery backup to the property, entire property will be on AC out 2 (essential loads). There is Pylontech lithium batteries, 12x 3.5kWh.

The client has an existing PV grid-tie system with a Huawei KTL12 3ph inverter.

We received wrong information regarding the Huawei inverter and now that we started getting documentation regarding the Huawei's frequency shifting parameters we noticed that it doesn't support frequency shifting. We need to find a solution for this as the client is not allowed to feed back excess energy.

a) For now I'm considering to purchase a Huawei Smart logger and a Janitza energy meter to at least enable the zero export function on the PV inverter. The inverter will then be connected without any other loads on the AC out 1 of the quattro's so that it switches off in the event of a power failure (we cannot frequency shift so we don't want to damage batteries etc. if using on AC out 2 since the inverter will stay on at 100% output if it's getting a voltage reference from the inverters). Should this setup work? We know that the batteries will only get charge when AC input is on again since the inverter will only then switch on. The Janitza meter for inverter will be installed on the AC input side of the inverters.

b) When using a smart logger from Huawei it is possible to switch the Huawei inverter on and off with a digital input, will we be able to use the CCGX relay to switch this input on the smart logger on certain SOC levels? For instance switch the relay on at SOC 30% and off at 95-100%? The inverter will then output its production at 100% and switch off when the relay opens, and not gradually decrease its output as it would have with freqeuncy shifting, how should this affect the battery charge? If this option b is chosen we will put the inverter on AC out 2 so that the batteries can still charge in the event of a grid failure.

Both options above SHOULD be temporary solutions as my supplier says Huawei is working on new firmware to implement frequency shifting in their inverters, but that he's been asking them for over a year and they keep saying their working on it. When they eventually do the firmware update, we will change the system to a normal ESS system with frequency shifting on AC out 2 to control the inverter output.

Please mention any other workaround suggestions should there be any. Thanks in advanced.

Hi all,

Earlier this week, we've released a new version of the Advanced page of the VRM portal. Its now much more suitable to analyse the data of an installation.

Hereby some screenshots to show the new features.

1. The first shot shows the main page. Note the little triangle on the lower right, it allows to drag and resize a chart. You can choose between 1, 2 or three columns wide.
   
   
2. The second shot shows the dragging: you can now drag the charts. Together with the resizing, this makes it possible to very easily organise what you want to see on one page. Super handy when analysing and looking for a specific issue.
   
   
3. Another way better working feature is the date picker. See the third screen shot.
   
   
4. Also, you can now easily go from one page to the other, clicking the arrows left and right. See fourth screenshot.
   
   
5. Lastly, the Selector is much more organised. See fifth screenshot.

So; not a question; this post is just to make sure all of you are aware of these improvements.

Best regards, Matthijs

I just used VRM to check and update the MPPT100/30 firmware and now get an error notification '#119 settings invalid' with the Bulk and Absorbtion LEDs flashing.

A reset (or several) doesn't help. Any suggestions?
What settings is it talking about? I only know the automatic voltage setting and the battery type.

I've got a 12v 320Ah Narada Lead Carbon battery bank, a Multiplus 1200/12/50 and 3 SmartSolar MPPT 75/15's connected to 3 separate solar arrays.

The problem I'm having is the MPPT controllers tripping over each other going into float WAY too early. So on the daily chart I'll have one controller yielding as much as 1300Wh while the other two will yield as little as 200Wh each. At the end of the day the battery is not fully charged either.

The dominant controller can be any of the controllers on any given day. The wiring and settings are the same for all three controllers. I guess it just a software race condition which one detects the 1A float first. As soon as is does that 1A load goes to the remain controllers.

Is it possible to have them share better. Does the BMV or Smart Sense Synchronise them at all. As it is they are operating at about 30% efficiency once two drop out.

Seems that only one MPPT controller can be the only charge source in the circuit. Otherwise once any one hits the 1A float threshold it go to sleep and doesn't wake up again. Leaving just one controller to do all the work and the battery no where near charged.

The situation is exacerbated as the Muliplus charger starts up when the generator is fired up. All the MPPT go to sleep because the generator is providing all the charge current. Then when it is turned off often only one charge controller comes back to charge and the other two stay on float even though the battery might only be 30% charged because the float voltage being reached does not wake them all up.

These MPPT charge controllers do not play at all well with other charge sources. Including their own kind. Is there any way to have them act as a simple power supply? That is just providing a voltage to battery and allowing the battery to simply absorb what it can? Or maybe get rid of the 1A threshold or have a timer that checks periodically if the battery can now accept greater than 1A and go back to absorption.

Basically modify the algorithm somehow so they're get back to work when they can. At the moment it's like having an employee that gets things done in the morning then goes to sleep and doesn't bother checking if more work has arrived because the other bloke is doing it all by himself and struggling at it as a result.

Seems theses things are too smart for their own goodand as a result are constantly tripping over each other. After which they don't get up and back to work again for the rest of the day! If it was an employee you'd fire them for not being team players! Lol

Is it possible for me to just move the charge leads from the battery connector to the output connector? If the MPPT can output 15A at say the float setpoint voltage to the output without a battery in the battery connection then that would be better charge controller than all the current "smarts" before the battery connection terminals!

Any solution would be appreciated.

Cheers,

Troy

How to setup the old Multiplus with 19xxxxx firmware so that the Tesla is charged and discharged correctly ? I mean setting up minimal and max voltages.

I recently had my system upgraded and settings set as per your "Victron & Pylontech US2000B and Phantom-S" manual dated 2019-01-22 14:42.

System has following devices and firmware ;

Color Control GX v2.23.

Multiplus 48/5000/70-100 v433.

BMV-702 v3.10.

BMS Pylontech with 4 x US2000B Plus batteries.

BlueSolar Charger MPPT 150/100 v1.39.

On running with DVCC for 3 sunny days, I got the following ;

[image]

Switched off DVCC and after a few days system stabilised as follows ;

[image]

Note : During "Absorption" phase System Battery Voltage reached 53,19 V and SOC 100%.

During "Float" phase System Battery Voltage drops to 52,98 V and SOC 100%.

I have also noticed the values of "Blue Solar Charger MPPT 150/100 - Networked operation - Charge voltage ; are 52,40 V with DVCC on, changed to 54,40 V when DVCC was switched off, and is 57,20 V when system is stable and fully charged. Where does this value come from ?

Any assistance to resolve this problem would be appreciated.

Thanking you,

My Venus GX is regularly, but not permanently connected to the internet and up until now has updated its own firmware automatically without my intervention. Today when I looked at the remote console I could see the message ‘installing firmware 2.30’, or something similar. This message never went away so I went to the menu option to revert to the original firmware. Now I can’t access the unit at all. The WiFi in the unit is disabled and the fixed IP address that I set for the unit, connected to the LAN, does not respond to a ping.

How can regain access to the unit?

Hello guys,

I have installed a 150/35 MPPT Smart Solar charger in my van and it is driving me crazy with the noise it produces. Once I disconnect the solar panels, the noise is gone.

[image]

Is this normal, something I have to live with or is there anything that can be done?

Thank you

When turning on (tried bouth "ON" and Charger only") it is no response at all. 220 v input and the feeder cable is OK and I have pushed the red circuit breaker several times. New 150 Ah AGM Battery. No response at all!

I would like to build a installation with a MultiPlus 2 and ESS in Germany.

I have now learned that all inverters since 27 April 2019 must have VDE-AR-N 4105:2018-11.

But i only found the "Certificate VDE-AR-N 4105 MultiPlus-II and MultiGrid-II 48/3000".
Inside it says "VDE-AR-N 4105:2011-08".

Someone can tell me if I can build that up and register with the existing certificate.

Or do I have to wait for a certificate with "VDE-AR-N 4105:2018-11"?

Suggestions welcome. Thanks.

The CCGX and Fisher Panda i-generator is set up via FP-BUS to VE.CAN adapter cable. The auto-start function of the generator is enabled, but it is not possible to use the auto-start function from the CCGX. It is only possible to start the generator manually, when entering the Fisher Panda gen-set via the device list of the CCGX.

Is it only possible to use the gen-set auto-start feature via the CCGX relay output?

I've set in Venus OS automatic start if voltage drops below certain value and it doesn't start even if voltage drops 1V below set parametr. Fortunately it can be triggered on inverter output power set, I assume the automatic start / stóp function works but not with voltage parametr.
