I have a similar query to the original question “MPPT 75/10 INVALID HISTORY”

posted on JUly 10.

I can understand the original explanation about the MPPT only distinguishing a day by the commencement & finish of solar charging, but can’t understand why it would vary the previous days readings each day. If it can’t distinguish a day/night cycle in the first case, how can it cycle through each day in the 28 cycle. I’m a little confused about the latter.

Hi all I have a 20w solar panel connected to my Blue Solar PWM light 30A to 12V battery. What is the best setting for load output for trickle charging the battery? Is it bad to do load output controlled by battery voltage or should I set it to dusk to dawn or a particular number of hours after sunset? At the moment, it is set to debug mode.

On which side of the resistor (shunt) do I connect the chassis ground wire? I have a diagram, but don’t know how to upload to this question.Battery Wiring.pdf

The two diagrams (attached below) that are part of product documents are confusing with respect to the interpretation of the battery ports on Cyrix ct 230. It isn't clear at all which port is for start battery (I guess this is what is meant by battery 1) and which one for house battery.

Please help.

Thanks a lot for advice

I have seen this issue mentioned before with Fronius PV inverters, which I think may have been fixed in a firmware update for the Venus OS. I however have a SolarEdge SE10000-H US inverter, which operates on 2-phases, L1 and L2. I only have 2 phases, not three total. I have a 2-phase MultiPlus system, operating on L1 and L2 as well. However, this is what I see when trying to configure my PV inverter:

[image]

And as a result, this is what I see on my console, which causes incorrect readings in VRM:

[image]

Is there a workaround, or upcoming fix in future firmware that might address this issue?

Equipment:
Not so new but still good Trojan deep cycle 6 volt large battery bank (12 units),
Charging system:
Solar panels, micro hydro electric,
New Genset Honda 2200W Inverter connected to battery charger.

I can't get the charger to stay on "Bulk charge" like it should. The built in charger kicks off quickly to taper down to float charge way before the battery bank is not even close to be charged. It usually kicks off Bulk charge in about 5 minutes.

• I keep the multi control setting at 18. (Could it be higher with 2200W genset???)
• Solar panels/micro hydro seem to charge the battery bank no problem...

Possible causes of charger Bulk charge issues?

1. My guess is the battery bank is getting old and I need to readjust the settings (INFO PLEASE...)
2. Wrong charger settings? (INFO PLEASE)
   
3. Bad connection? (checked everything)
4. Faulty temperature sensor? (Checked connection) (Should I disconnect it for test?)

I disconnected the solar panel system and getting the same problem...

Thank you Victron. These units are amazingly durable and well built. This community page is well put together AND HELPFUL (I hope!). I will definitely get a new unit if this one ever gives up...

Hi folks,

I will be hanging new PV tomorow morning and would apriciate some input.

I have a new Easysolar 5000 hooked up to a BYD 13.8 kW Lithium pack.

Obviously I will set the MPPT as directed in the manual, which I havent read yet, but I am also aware that the BYD battery manager, via the CCGX is going to 'manage' things.

What I dont know is how it will manage things, what I should look for to establish that all is well and if I need to make any changes to the MPPT settings, which I assume I will.

My supplier told me I needed a programming cable, USB to VE Direct I think, which I have but I havent found what I should be doing with it yet...

I still have manuals to read but the BYD manual dosnt mention MPPT settings, speciffically, and thus far I am unsure what software I need to program the MPPT in the first place. In addition The manuals for Victron kit havent, so far at least, been speciffic about BYD kit and I am not expecting the MPPT manual to be any different.

Am I correct in assuming I unplug the cable to the CCGX to program the BluePower and if so is VEConfigure what I need or something else.?

Any help/pointers would be appriciated. I am pretty sure there is potential to get this wrong and I would rather not do that, damaging 6k's worth of battery because I used the wrong setting is not a place I want, or can afford, to be.

Thanks, Al

Hey Guys, i have a Victron mppt 75/15 and iam using 3x 100 Watts solar modules with it. they are Connected in Series and gave between 200-250 watts in good conditions. I also use a 72AH battery. Devices like fridge and lightnings are connected to the load Output.

My Problems is: i set the Max battery Charge current to 7A which is the best charge rate dir this battery to Get a Long lifetime. The battery Starts charging with 7A, but every additional cunsumer like a fridge with 10A Drops this current. In the example of the fridge, the battery is discharging with 3 Ampere. Now i change the Max charge current to 15 A and the problem seems Solved. 5A charging the battery and the Rest 10A powering the fridge. But if i Turn off the fridge, logically the battery is charging with 15 A. I think this is a bug in the Management of the current. What do you think? Also also recorded this behavior which german comments:

Hi

After some information as to how the above components will react together in a ac coupled off grid system?

I understand frequency shifting will restrict the pv from the Fronius

How does this perform or react if there is a generator running for supplementary battery charging ?

Regards mike

G day, I have bought the mppt 20/100. I have added the device to my phone and can connect to it via the app. Once it has connected it shows me 3 options only. If I click to change the pin I “think” it works, but not sure as there’s is no obvious change. if I try to change the name on my android phone and on my iPad it crashes the app. If I hit to update the firmware it opens a blank firmware library page. Both my android phone and my partners iPad render the same result. What am I missing here? I have power cycled ever which way, removed apps etc and I always end up with the same result. I am connected only to a battery as I am bench testing. A solar panel will come later once I get this talking to my phone correctly.

Looking at a days data from the Portal for my setup, I see a small number (89 out of the 1524 records for the 24 hours) that have for MPPT Controller State the entry "Voltage or current limited".

I would have thought this entry would occur if the PV voltage or the PV Current was over the rated value (so for my 100/30, a Vpv of >100V and a Ipv of >30A) but those values have not been exceeded so cannot see why this would appear?

This is the MPPT Info as seen by VRM:

[image]

I have a small extract shown below -

[image]

Vpv and Ipv are well below the limits; it encompasses all charge states and is not linked to any band of battery voltage - Below shows the other extreme of battery voltage -

[image]

What values in the data above would Voltage or Current limit a SmartSolar 100/30?

It is only a very small time within the day but on checking the logs it is a daily occurance but with no apparent reason. It would be good to know what the reason for this entry is.

We have a 3ph set up with MP2s with an ESS. We have the system working with a changeover switch, the system operates without issues bypassing the essential loads/charging the ESS and powering the loads from the Grid. We have only run the system powering the essential loads from the ESS for 10mins at a time, it operates as expected during those tests. The 1st incident after 7 days of faultless operation and second incident after 11 days of faultless operation, Relay Test Fault. The system appears to auto run a random relay test. It fails the test and switches off, Error 11. It appears that they were #45 0x8200024 (Error Occurred GND Relay Error) and #50 0x800002 Relay Test OK PE2 Closed Error (but states Relay Test Fault in Alarm Log) errors. These errors ocur out of office hours and no one is there to reset right away. When staff return and reset system it operates. Elec Eng is sure N and E are bonded correctly and seperate between essential and non-essential boards. Without this random test we would be fine. Can we stop this test from running?

Hi,

I have a Phoenix Inverter Compact 2kVA which I have been using satisfactorily for over two years and am now wanting to use my BMV-700 to provide auto cut-out to protect the batteries from excessive drain.

The short question is: can I directly wire the BMV-700 relay into the Phoenix remote switch terminals to achieve this or should I use a further external relay between the two?

The longer background to this is … I changed the DIP switches in the Phoenix to select remote switch operation and wired in a simple manual on/off switch to the terminals on the circuit board. Using this manual switch, the system continues to operate as it has done since 2017. When I replace the on/off switch with the BMV-700 relay, the Phoenix starts up ok (with minimal load of just my internet router), but when my fridge is turned on there is a large, prolonged power drain (c. 1kW) from the batteries (as observed on the BMV-700), the inverter fans start up for a couple of seconds and then the inverter auto powers off (the BMV relay remains on). If I revert to the manual switch everything is fine again (there is of course a very brief power surge when the fridge starts, but it settles to the 100W steady state within a second or so and the inverter fans have no need to activate). I have repeated this three times, each time the fridge causes this large power drain with the BMV but there is no problem with the manual switch. This makes no sense to me!

Any help or thoughts appreciated!

Hello, I bought a Venus GX and I can't add the installation to the VRM plataform, every time I try to request access, it appears the same message: "All administrators of the installation have been notified by email. It will be accessible for you after one of them approves the request"

It is a new device, I don't know why the message appears, could you help me, I already try everything, already upgrade the version, check the internet and nothing.

Please help me

why do I have a voltage on the quattro 3000 with "ac 2 in" when shorepower is connected to "ac1 in"? There are no assistants or relay enabled.

Hi

I'm going to be upgrading my system on the boat. I currently have a victron multiplus inverter charger 12 / 1600 / 70 which I would like to upgrade to a victron multiplus inverter charger 12 / 3000 / 120 apart from the battery cables to the inverter charger would I need to upgrade the shore line cable from the plug to the inverter. I've also been told that if I add a victron isolation transformer 3600w this will help to smooth out the electricity coming from my kipor 6.5kv generator. At the moment the washing machine sometimes plays up due to what I've been told dirty electric from the kipor generator. Thanks

After update to 1.42 on smartsolar, victronconnect can't save the settings from smartsolar to file.

I'm running victronconnect on android version 9.

Is there other than me Who has this problem?

Is there a solution?

Am I correct that I cant use the Victron Connect Windows app with my Victron Bluetooth enabled devices? Why is that? My laptop can pair with my BMS and charge controllers but they dont show up in the Windows app.

Is there anyway to contact Victron Support directly? I bought the MultiPlus through Amazon. Victron wants support to go through dealer. I sent an email to Victron and got a reply that email ls was being forwarded to the dealer. I need a firmware update to make charging a Tesla battery compatible with MultiPlus. My concern is getting the right firmware update. I don't want to do more harm then good by installing the wrong update.

Good Day,

My Inverter has 2 AC outputs , AC 1 and AC 2 . AC 1 reads 230V but AC 2 has a much lower voltage . Why is that? I wanted to connect my non-critical loads to AC 2 but its way too low.

Regards

My Lead Acid OPzS battery bank is "becoming smaller" as I continue to load the system more an more. Initially I sized the system for 20% DoD, but now in next winter I am afraid it may reach 40 to 50% or even more.

I have now the chance to get a good priced set of Winston LiFePO4 90Ah cells and I was thinking to build a smaller independent system to offload some of the work of the main system.

I allways thought it would be not advisable to put lithium in parallel with lead acid, but the more I think of it, the less crazy it seems. My LA system is 24V based, the 8 cell Winston would be 25.6V nominal. I would source a 3rd party BMS to manage the lithium. Maybe the BMS can take care of the issues - disconnect in low and high side of the daily swings.

I actually have found a product to make hybrid battery banks (BOS - LE300) so maybe this isn't so crazy after all.

To install in parallel and monitor the 2 strings I was thinking if it would be possible to use a separate BMV on each string (Lithium and OPZS). Is this possible, using 2 BMVs on same Venus device?

Hello,

I have an ESS 3-phase installation with 6 MultiGrid 48/3000/35-50 (two on each phase).

The system runs fine except this famous relay test.

I tried almost everything to troubleshoot this error, but before I try to contact my vendor(s) for the Multis, maybe someone here has an idea.

First of all, the error happens with or without load at the Multis. Without load means that there is nothing connected to the ACout of the Multis.

If I disconnect the Grid from the Multis (ACin), the Multis disconnect Active(in) and Neutral(in).

Measuring now the impedance between Neutral(in) and Neutral(out) shows > 5M Ohm, which looks correct for me.

Measuring Neutral(in) against PE(GND) shows 0 Ohm, Neutral(out) against PE shows > 10M Ohm.

If I disconnect the PE (GND) from the Multis the relay test passes without error and everything runs smooth.

I got my first 3 Multis about a year ago, the others are from October last year (1) and from two weeks ago (2).

For the error details see the attached pictures.

It would be very helpful to know what is tested during 'step 6'.

Any help is very appreciated.

All- Just purchased some new 6v VMAX 225 batteries (https://www.vmaxtanks.com/V6-225-6Volts-225AH-Deep-Cycle-High-performance-AGM-Battery-_p_48.html ). Two of them in series to obtain 12 volts. Few basic questions:

1) On my battery Monitor (BMV-700) -- When setting the capacity do I set 225 ah or 450 ah? Bit confused because although there are two batteries at 225 ah they are only at 6v vs. 12.

2) On my Victron MPPT 100/50 solar controller -- Is battery type 2 correct on the rotary switch? In addition should I leave the default settings or change them to something custom?

3) Any other setup items on the solar controller or battery monitor I should be looking at?

Thanks all in advance!

Hi,

I just installed a Cyrix CT 230A in my car. After I finished the installation I recognized that I connected my starter battery to the port "Battery 1" (because I thought Nr 1 must be the main battery in the car and my aux battery to the port "Battery 2". Now I've seen that it looks like it is turned around in the manual. But I'm not sure because the ports are not numbered in the manual. Do I have to change my installation?

Thank you very much for helping!

Regards

David

Ever since the redesign of the VictronConnect app (v4.0) it has many small issues. (So since January 2018) I just want to report them so that Victron is aware and can try to fix them. This all applies to the Android version of the app.
- The most obvious issue is that many times switching screens ("Status", "History" and the recently added "Trends") sometimes doesn't work very well. It either doesn't work at all or it only works with swiping to the next screen or it only works with clicking on the screen title at the top. See this YouTube movie:
https://www.youtube.com/watch?v=NQ498dEqoVA

In text: Click on 'History' and nothing happens. Only when you swipe left, you go to "History", When you swipe right in "History", sometimes nothing happens, Click on "Status and nothing happens, Then when you swipe right you now go to "Status", etc.

Futhermore over time I have noted down these issues:
- 20190324 Sometimes when pushing a bar of a day in the "History" overview, you don't get the break down into "Bulk, absorption and float". Sometimes it works, sometimes not. I didn't find a pattern.

- 20190324 Sometimes nothing happens when you push on the "Battery" in the Settings menu.

- 20190324 Victron Connect report had wrong name: "Victron Connet report", so without the "C".

- 20190324 It is possible to get the status screen of VC back from the previous used apps or from the lock screen, while the Bluetooth is off. The status screen then shows old info, but doesn't tell you that you are disconnected. This can cause confusion.

- 20190324 In this state the screen also messes up sometimes. The yield screen stays on top of the numbers when you scroll the screen up.

- 20190324 And the status screen stays frozen when you reconnect the Bluetooth and return to the Status screen. Have to exit the Status screen to refresh the Status screen.

- 20190325 No break down of 'Bulk, absorption, float' in the first 'graph' (of today). The other days do break down. The break down of the graph of this day did work earlier in the day.

This all makes me actually wonder if Victron has a person that tests all the software before it is released, (this used to be my job at another company, that's why I am asking) because these issues are very easy to catch and some of these issues have been present for almost 2 years now.

Is there a Bluetooth device sold on the open market to plug in the MK3 USB so I can convert my MK3 to a BT option without having to purchase a new Smart Victron Bus Dongle? Why does Victron sell outdated products when new ones come out?

MultiPlus-II 48/5000/70 is shutting down continuously with an overload error after some issues on the grid network.

Batteries are full and the external grid is off (as the mains circuit breaker failed). BlueSolar Charger MPPT 150/70 is connected and providing power (as the sun is up...)

Now the MultiPlus keeps trying to start up, but fails within a couple of seconds with an overload error. However, the circuit breaker towards the load is off as well, so there literally cannot be any load on the inverter at all.

Is this a bricked MultiPlus or is something else going on?

Tried a lot of stuff, including restarting the system through the Color Control GX as well as with the on/off button itself.

Anything else to try?

The system is installed in the south of France, and I'm asking for someone else, so troubleshooting is going to be a pain.

Hi,

What's the max. size cable that will fit into Lynx Power In.

Thanks Tony
