I was able to access my MMPT SmartSolar 100/50 Charge Controller via the Victron app for the first few months after it was installed - however it no longer will show up in the Victron app. I have the Victron battery monitor which continues to show up in the app with no issue. This is all being done on the same Iphone that I have had since the beginning. I have reset all bluetooth on my phone, reinstalled the app, tried other phones - but the charge controller does not show up on bluetooth. The charge controller appears to be working fine, I just can no longer access the data via the app. The controller hasn't been moved or tampered with in anyway. Trying to figure out if there is something else I can try...

I've got a kindle8 and need the app for my 100/30 controller. Apple app store doesn't show anything for victron. Could someone post a link where i could get it? Thanks

Hello!

I am an electrician and planning a ESS-system for my new house in Austria.

3x Multiplus-II 5000 (3-phase) with 48V Lithium-Battery (maybe some Pylontech US3000), with about 6kWp Fronius Symo PV-Inverter connected on AC-Out for higher self-consumption and UPS in case of grid failure.

Is there an extra anti-islanding-relay necesarry, or is the anti-islanding-protection from the Multiplus II enough? I only find the TOR D4 Certificate for Multiplus-II 3000!

Thanks for the Answers!

Hi - If somebody can help on this.. If you see below my battery is on float state and reading shows 54.9V. But the setting in the configuration for float is 55.2V. But the charge never goes beyond 54.9V and its always charging. When I check the voltage at the battery terminal its at 55.2V.

Is this an issue if its always charging or why does it no go beyond 54.9. The distance between the battery and the Easy solar is less than a feet. How do I correct this?

When programming 48V off grid systems with lithium batteries, I have found that the the 'DC input low restart' value's minimum 4V above the 'DC input low shutdown' voltage to be way too high.

My feeling is that this 4V margin is intended for lead-acid batteries, but it is not suitable for the much narrower operating voltage range that many lithium batteries have these days.

It is important to have low voltage shutdown set correctly to protect the batteries from over discharge, however, if this does occur the system won't restart again until the batteries are almost full!

I have also found this to be problematic in the event that a system is at a partial SOC (say 40% for example) and it is shut down manually for maintenance reasons. In the process of shutting the system down the inverter experiences a 'DC input low shutdown' voltage (momentarily before it dies). Then when the battery is reconnected the inverter won't turn on until it reaches the 'DC input low restart' voltage which corresponds to a SOC much higher than 40%.

~~~

Another feature that would be nice would be to be able to shut the inverter down on a set SOC outside of the ESS assistant. Or maybe this is already possible by way of virtual switch, which I haven't explored much yet??

Hi

I have a 2 week old installation of OzPv gel batteries charged by a Victron MPPT 250/100, a Multiplus 5000Va inverter and ColourGX. I get no battery SOC even tho the MPPT knows when to move to absorb'float etc during daytime and the Multiplus knows how much charge taken from the batteries. Is there a setting for CGX to display SOC or do I need more hardware?

Thanks. You guys do a great job!

Firmware update for Mulitplus2 Ver 2625460 causes unit not to go online or connect to the grid

at all. Reinstalled old version 2625459 all is OK? Any answers to why?

My fronius primo is not producing power when the grid is not available while it is connected on the AC 1 Out of the victron multi but it stays ON. How to fix this?

A while back, I bought a BlueSolar 100/50 with the old style VE.Direct Bluetooth dongle (ASS030536010.) All new and boxed.

I have now decided to upgrade my system with much more stuff...

- a new SmartSolar 100/50 to swap for the BlueSolar 100/50 + VE.Direct Bluetooth dongle

- a second SmartSolar 100/50

- Winston LiFePo4 700Ah battery bank

- MultiPlus 12/3000/120-50

- REC Active BMS though VE.CAN interface

- CCGX acting as the SOC% meter with DVCC from REC and interfaced to MultiPlus VE.Bus

- USB Bluetooth dongle for CCGX

My questions are:

1. I have read on this forum, that I can expect the REC ABMS to monitor the LFP battery bank, and transmit SOC% via VE.Can to MultiPlus and SmartSolar which will stop charging at my defined limits.

2. Should I buy 2x SmartSolar 100/50 and sell the BlueSolar on eBay? I think I need the VE.Direct to interface to CCGX, rather than connecting a Bluetooth dongle. And I very much want to connect to both controllers via Bluetooth with the Victon Connect app. (The VRM looks very nice, but I prefer seeing the info direct on a native App without all the WiFi browser stuff.)

3. In other words, am I right that the CCGX does not transmit over bluetooth the information it receives on VE.Direct from the SmartSolar / BlueSolar - as a native device for viewing and configuring on VictronConnect?

4. But the CCGX does receive full data and configuration from the MultiPlus's VE.Bus and shows this on Bluetooth? Or do I need to buy the Smart Bluetooth dongle to achieve that?

5. I don't plan to buy BMV-712, as the REC BMS sends SOC% data direct to CCGX using DVCC. Will this be visible on Bluetooth somehow from a Victron device? I think I am correct in thinking that the REC BMS is more likely to get an accurate count of SOC% than BMV712, as it is counting Amps / Coulombs and resetting SOC% according to cell voltage heuristic. (If that sentence makes sense!)

5. I don't think I need Ve.Bus USB MK3 adaptor (ASS030140000) as I can use the web browser interface to CCGX to make initial configuration / download & upload settings and firmware. Or should I buy one just to get things setup?

6. How do I get the CCGX on Bluetooth - is this internal, or should I buy a USB bluetooth dongle. I have seen models recommended in the documentation. Is this the best way to do it for a decent range i.e. 10m? I think I read in the Venus online manual that the range was very disappointing.

7. Am I going about this the wrong way? Is Bluetooth configuration / monitoring reliable enough (on a 14m sailing yacht) to be the fundamental connection monitoring method? I am currently viewing the CCGX as an auxilliary display - I don't plan to 'go downstairs' to touch the buttons very much, as I would rather sit in the cockpit to view the status of the system (on my waterproof Sony Tablet!) Am I dreaming the wrong dream?

Thanks for your suggestions. Andy

Hello,

A Victron Multigrid 24/3000 is used as a grid back up.
A 30mA differential relay is used at its output.
The relay trips with no obvious reason.

a) Whenever the unit switched from inverter back to mains on (i.e. when grid exists again)
After this tripping the relay is armed to operation and works normally but on (b) below.

b)for no reason and at irregular intervals. The relay if armed does not trip again but after some random hour.

I have a problem multiplus 24/3000/70 all the lamps of the panel are on any solution

I recently bought to my existing system a Victron SmartSolar Charge controller MPPT 100/30. The idea was to replace the old controller with this one. Well, now when I wanted to install it I noticed there's no incoming place for the cables going to the load (lights, usb and so on). In all the controllers I've had before there's been incoming connectors for the battery, the panels and the load. So sorry for not getting this, but how do I do this, what is missing?

Hi,

I have just installed a multiplus 12/1200/50 into our boat, I have connected it up as per the manual. It is connected to 3 x 95AH AGM batteries and a single 100AH start battery, all of which are new. I also have a separate solar input to these batteries providing a charge.

On switching on the multiplus the orange light comes on briefly followed by the green light briefly then there is a click sound and the red alarm light comes on and stays on. There is no output from the inverter to the sockets via the distribution box. I have tried disconnecting both the AC input lead and the AC Output lead and the same thing happens which leads me to believe there may be an internal fault.

The unit is about 3 years old but has not been used before as was originally bought for a project that never happened. I don't yet have any monitoring VE.direct cable or bluetooth system so am unable to update the firmware or see the settings, however the dip switches are all set to their defaults.

Any help would be gratefully received.

Many thanks

Gavin

I have the above system with the Pylontech batteries as the latest upgrade due to failure of Deltech Lead crystal batteries. It seems that the Blue Solar MPPT chargers are communicating at the 250bit Baud rate and the rest must now communicate at the 500bit Baud rate.

Current workaround is to set the Quatro as the BMS and have the rest of the system at the 250bit which is not perfect.

What is the most cost effective solution?

Dear sir

You know that when we size a solar PV system some simulation is required to assure system performance

We use software called PVsyst, but we don’t have Victron charge controller and inverter product in our database

So please could you provide us with these data especially:

• Charge controller 250/85, 250/100, 150/35, 150/85, 150/100 (extenstion of the file .RLT)
• Inverter Quattro and multiplus (extenstion of the file .OND)

This will help us greatly to promote victron product to our client through our system designs

Appreciate your support

Hi,

Offgrid MP + AC coupled SMA Sunny Boy (SB) with lead carbon super capacitor batteries. An additional BlueSolar MPPT controller is planned for the future but currently not connected.

I'm looking for more information about DVCC as I see unexpected/undesired behaviour, where the MP is telling the SB to reduce power generation (possibly to the point where the SB reduces power output to 0W) and subsequently starts to use the batteries to provide power to the loads. After a little while, the SB ramps up power generation again (presumably in response to a lower frequency generated by the MP) and provides power to the loads and the MP starts charging the batteries again. This seems to particularly happen once the batteries are full.

While this might well be normal when an addiotional load just comes on (and the SB was more or less idling due to full batteries); I would not expect it to happen during the time that a larger load is present. Note there's normally an AC base load of at least 100W.

Does it make sense to enable DVCC in VenusOS for this AC coupled system? Where can I read about how this works in more detail? I did look at the Victron manual page and also searched the internet but so far haven't found much that is relevant.

Diode D17 between the two input terminals! model 750 12V!

Does anybody know which diode is this D17, between plus and negative terminals on the phoenix 750 12v inverter? victron energy representatives replied to me that they don't have any more the technical manual of this old top secret product so nobody knows anymore or they do not wish to share this highly important information!

Good Day

I have the 6KW 48V Blue Nova LifePO4 batteries connected to a Multiplus II, on ESS.

I have 2 issues I need assistance on:

1.When we have mains power fails and running on batteries, how do I limit the current \ power drawn from the batteries\system during this UPS mode to say 1000W (eg. System protects itself by shutting down if an hair dryer, air conditioner or kettle is connected)?

It was easy with the Hub-1 but cannot figure out how to do this on ESS. Impact is if we have no mains supply and run on batteries and don’t know that there is no mains, batteries drain quicker if we use high power devices.

2. Any idea why I receive high battery voltage alarms from the Blue Nova BMS at times?

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.

I tried to search but I am unable to find out how to turn the load output of my smartsolar 100/20 mppt back on. Resetting with the victronconnect app does not do it. Smartsolar has the jumper removed.

Twice today the load output switched off. First time when connecting a 12v pc adapter/charger to the load output. It came back on after i disconnected the adapter, set the load output to off, then back to batterylife.

Second time when I connected a Lipo rc charger to the load output. The charger was in idle mode, not connected to anything. I disconnected it, tried the same procedure as above (+"allways on"), and even reset the smartsolar with the app. I still have no load output.

The smartsolar is hardwired to two lifepo4 100ah battries and two solarpanels (in parallell). The installation is in a cabin with quite long cable stretch, previously powered by 3 AGM batteries and a PWM regulator with no such (but other) problems.

Any ideas?

Smartsolar firmware is v1.39

Hi, I need to enable "Battery Monitoring" function in the General Tab of VEConfigure. I need to know;

a) "State of Charge when bulk finish" - its meaning and optimum setting point

b) "Battery Capacity" - what battery rating should be put, e.g. C1, C10, C20,,,,,,,

c) "Charge Efficiency" - What should be the optimum setting for it

Thanks.

Hi,

I have been using a MPPT 100/15 Bluetooth controller for the past week and starting yesterday the the controller has been randomly disconnecting the load. After noticing the load is off, when I open up the Victron connect app and the Bluetooth connects, the load switches back on. It happens in every load setting even “always on” I have been doing some research but can’t find any answers. Please help!

Thanks!

Hi All

Been in contact with the place I bought my BlueSolar 75/15 and Bluetooth dongle and want to hear if someone experienced similar

Its installed in a 4x4 with 100+80w solar panels in series (lots of cloudy days in scotland) It feeds a 12v 90ah deep.cycle battery which mainly runs LED lights and a fridge. Battery is connected to started battery via a Victron Cyrix battery combiner.

Been working well for 2 years and then other day noticed when turning rear LED worklight an approx 1amp load the light output is low and constantly fluctuating. Measured load terminals on the Charge controller and it swings from 5 to 11 volts. The battery voltage is stable at 12.50v at same time. Day was sunny and 34v from the panels and charging state float. When turning on more lights the load voltage drops to 0v and at somepoint it came up with battery overvoltage 23v alarm. Switched loads off and voltage dropped slowly to approx 12v. When disconnecting solar panels and in evenings the unit turns fully off, no light in diodes and not visible via bluetooth

When the engine is running and battery combiner is active both batteries are 14.2 volts. Battery terminal of charge controller is stable at 14.2v Thou when load above 1Amp is applied the same voltage fluctuation in the victron app occurs and lights goes dim and bright randomly

Tried disconnecting the main battery and no change in behaviour. Tried another LED light with approx 1.5amp load and same story.

Is it a faulty unit or is there something else that needs to be looked at? The battery overvoltage error really puzzles me as no changes to wiring and then appears normal again.

Regards

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.

Hi,

My BlueSolar MPPT 75/50 (v1.12) has been working for many years, I recently connect to my laptop and VictronConnect, it detected a new firmware v1.39 and I have to upgrade to continue using VictronConnect.

I upgraded the firmware but now charging staoped and there is a error on Victron software "#116 Lost Calibration Data" its not working anymore. Bulk and Absorption LED flashing blue simultaniously.

I down loaded v1.43, upgraded but still same issue.

Can anyone help revert back to the original firmware v1.12 please, my device is 6 years old so cant send back to dealer.

Any help will be appreciatded.

Hi all,

I have a multiplus 24/2000 50/30 & a 150/50 MPPT with 1200W pv array & 340AH 24v bank.

I’d like to replace my batteries with a 550AH 24v bank & keep DOD below 30%.

What I would like to know is whether or not it would still suit my multiplus having the higher capacity bank or should I keep the bank a little smaller, say around 450AH?

Thank you for any information & feedback.

I have a multiplus 24/3000. 400AH @24V lithium battery bank. I want to heat hot water when on shore power and also when battery is close to full. Heating element 1500W. (it is in a heat exchanger that is heated by bus hot water too). I am looking at powering hot water off multiplus the AC2 circuit. Looking to use the generator assistant to control the AC2 outlet

*)Use ACOut2 relay to start generator

*)’open relay to start generator' - this inverts the logic

(start generator = open relay to turn off ACOut2)

*)’start generator when load higher than 5000 W for 5 seconds’ -and

Open ACOut2 when load higher than 2400W for 10 seconds

Turn off hot water when load higher than 2400W for 10 seconds

'stop generator when load is lower than 1800 W' -

Close ACOut2 when load is lower than 1800W

Turn on the hot water when load is lower than 1800W for 10 seconds

*)’Start generator when DC input voltage is lower than 26.5 volt' -

Open ACOut2 when DC input voltage is lower 26.4

Turn off hot water when voltage is lower than 26.4 will have to experiment with this to get about the SOC I want especially with voltage sag.

*)’stop generator when DC input voltage is higher than 26.61 volt' -

Close ACOut2 when the DC voltage is above 26.61

Heat hot water when the voltage is above 26.61

*)When the generator is started must stay on for a least 10 seconds

When ACOut2 is Open and the hot water system is off must stay off for 5 minutes longer.

*)The generator is not stopped by AC input

I am not sure about this command, I assume it applies to the assistant as a whole, that is not effected by inverted logic with the start/stop, but will allow the assistant to run or remain in its current state even if AC input is active. That is I have shore power.

I've seen another post from @Mitchorr but it didn't have an answer.

I installed the 712 on my motorhome with two 12 V AGMs in parallel, each one is rated at 92 A hr. The batteries are about six months old. I entered 184 A hr when setting up the 712. All the grounds go to a shunt and there's a single connection to the negative battery post.

The 712 always displays between 95 and 100% charge, even when the voltage display is 12.05.

When I have a couple of fans, the propane fridge, and the propane water heater on, I see about 3 A draw. When I plug in a portable 100 W solar panel, I see 3-4 A going in.

I've manually run sync, but that doesn't seem to have an effect.

Any suggestions on what I can check to figure this out?
