Solarertrag über Shunt messen und Anzeige im VRM

Hallo Community,

ich möchte den Gesamt-Solarertrag (von meinen 8 MPPTs eines Fremdherstellers) über einen Victron-Shunt messen und ins VRM einbinden. Wie bekomme ich die Kachel rechts unten angezeigt, die normalerweise "PV-Charger" oder "PV-Power" zeigt?

Geht das? Wenn ja, wie?

Vielen Dank im Voraus.

A new beta came out today that includes smartshunt 2.33. It failed during the upgrade. I now cannot connect. I get the message to install the firmware. Tried the officially released version and it fails also. the smartshunt is connected to my color control and appears to be reporting fine. I just can’t connect to it via Bluetooth without getting the message to upgrade the firmware.

Solar controller 100/30 not fully charging vmax slr155AGM

I have the controller set at the default 2 position on the dial. The first time I set it up, it got up to 14.4v and went to absorption, then to float. My battery was fully charged. The last two days (everything is new) my battery seems to get “stuck” at around 12.7 volts. I have 200 watts of solar. My battery is back up to 12.6 by noon, but it’s never getting higher Despite it being sunny. All afternoon I see anywhere from 70- 100 watts and 5-6 amps from my panels, but my battery voltage is refusing to rise.

FWIW, the battery and charger are in the same space and are the same temperature. Connections look tight. Things worked on my first charging run also, but not now. It was also in full Sun and got that day too. I’m stumped. Any ideas?

Big difference between from and to battery

If I look to my statistics in VRM on 30 days there is a big difference between how many power that comes from or go’s to the battery. In my opinion this difference can only be as large as my battery size.

12/24v Buck Boost Converter into Orion 24/48 Converter into MPPT to get 33V charging capability

Is this combination of components possible to utilize for the desired outcome of a 33v charge?

I've currently got the 12/24v buck boost converter in use but it can only charge my batteries to 30v. (my batteries are 28-33v operational)

I want to take that 30v and boost it to 33v and it seems the only way would be to use the Orion converter then send that into an MPPT.

Is this possible?

Thanks!

Are Assistant Programmable Relay 'Switch conditions' evaluated as AND or OR?

I want to make sure I've configured my MultiPlus' correctly. So far when I've used more than one 'Switch condition' all conditions were natually met so I still don't know if selecting multiple conditions are 'AND' values (all must be met), and not 'OR' (any combination).

I was able to verify the 'Extra drive options' are OR values by selecting 'in case of general system failure' and the assistant worked despite being selected. I've created quite a few programable relays to ensure they're evaluated as 'OR' values.

I suppose I can add another programmable relay with mutually exclusive switch conditions. I'd rather know from the source how they are supposed to behave rather than assume and potentially get tripped up on a new firmware release.

Multiplus 1600 Alarm - Solid red LED

Hi all,

My Multiplus 1600 has been working faultlessly for the last 4 and half years, but after putting it on yesterday, it cut out and the alarm led lit solid. Turned it off and on and after a couple of mins did the same thing. No flashing of error code, just straight to alarm on. Tried charging through shoreline connection and that worked fine. Put it to on after an hour of charging and within 20 mins it cuts out again. The manual states error codes for a flashing alarm led, but mine just goes straight to solid on. The voltage at the dc input terminals was 12.6v and I removed both ac input and output connections and it still cuts out. Any help would be greatly appreciated.

VenusGX mqtt unstable after 2.72 firmware upgrade.

After upgrading the firmware of my Venus GX to version 2.72 I am having issues with it not continuously publishing to the mqtt broker.
When I connect a client to the broker in the GX I receive the subscribed messages for about a minute after which an empty message is received and no more messages are received until about 1 minute or 2 later. This just keeps on repeating.
I suspect there is a timeout issue or it somehow does not get the keep-alive messages.

I was unable to find a change-log for 2.70 to 2.72.
I would also rather not roll back but I also cant seem to find a way to even roll back the firmware.

EDIT:
After creating a profesional account I am able to access the changelog. Though that did not really explain why mqtt is misbehaving in 2.72.
It did however point out how to roll back so I rolled back to 2.66 which resolved the mqtt issues.

However that may cause me to be unable to configure my EM24 ethernet as that was not yet added in 2.66.

SmartSolar 150-45-Tr Load output switches at half voltage set points
Re : Victron Smart Solar MPPT 150/45-Tr

The programmable relay in Load Output mode switches the programmable relay at half of the set threshold voltages, for both ON and OFF.

I have tried rebooting, resetting to defaults and re-programming. It is using the latest version firmware V3.02 which were updated via VictronConnect when initially powering up and programming.

The actual battery charge voltages appear to operate correctly as per their set points and the VictronConnect app is reporting the correct voltage in the status screen.

The Programmable relay is controlled by the PV voltage at the correct voltages if in Streetlight mode.

Battery voltage is set to 24V and all other settings appear to be correct, pics attached, please advise if you see a setting which might cause this issue ?

The same problem (Load Output switching at half the set threshold voltages) happens regardless of whether the Streetlight function is used or not.


e.g.1 :
Battery Voltage set to 24Vdc
Programmable Relay set to Load Output.
Load Output set to Conventional Alg1. (OFF 22.2V / ON 26.2V)

The Load Output only switches OFF (open) the programmable relay when the Battery voltage gets below 11.1V, and will switch the programmable relay ON again when the battery voltage gets above 13.1V (which is half the set point voltages).

I have run this test several times with different (custom) voltage set points and the Load Output always controls the Programmable relay at half the set threshold voltages (of battery volt).

Note : I am bench testing this controller before sending it to site using a variable regulated dc power supply to vary the Battery voltage, leaving for over 3 minutes at different voltages to see when the programmable relay (Load output) changes state, which is always at half the set points.


Does anyone else have the same issue ?

Regards

ScottR

Block-level system design for complete multi-source/multi-load Lithium-based system?

I've built some solar power systems in the past around lead-acid batteries, and they're generally fairly straightforward because of the ease of charging lead-acid. For example, I could feed a lead-acid pack with both a solar charge controller and a wind charge controller wired in parallel.

But now I want to build something with more options based around lithium battery chemistry. I feel like this has been done over and over, but I'm having a hard time finding an overview.

I want a battery-powered system of DC and AC loads (this part is easy enough), with solar, wind, and grid power inputs. The grid power has to be flexible, 120/240 V, 50/60 Hz. And it needs grid isolation (this is a marine application). And the batteries are lithium (probably LiFePO4), with all their attendant charging requirements (I know a lot of large Li batteries have some built-in BMS capability). And note that the DC load can be quite large at times (peaks of 20 - 40 kW). I don't think Victron makes anything that operates over 48 V, but 72V or 96V for the pack voltage would be a nice perk.

Are there any resources describing such a system? Thanks!

SmartSolar MPPT 150/45 don't go into Float

Hey!


I got myself a SmartSolar MPPT 150/45 - TR with the Display option. I switched from my 100/20 to the 150/45 because the smaller one was on its limit.


The problem that I encountering now: The new MPPT doesn't go into float.


It's connected via VE. Smart Network to a SmartBMV 712 and a SmartBatterySense. On the app, the MPPT says it's using external voltage and external Battery current sense from the BMV and Battery Temperature from Battery Sense.

Its also connected to a Raspberry Pi running VenusOS.


Right now, the MPPT is set to a maximum absorption time of 6h and an Absorption Tail Current of 4A. The MPPT as I'm writing this is charging the Battery with 3.1A (MPPT Reading) where 2A go to Battery (BMV Reading)


From my understanding, the MPPT should go into Float if the Absportion time is at max 6h or the Battery Current goes under 4A for one Minute.


Today it started charging with 11.8V and is in absorption for 4 hours.


Typical days are, charging bulk over the day, going to Absorption, Battery Current falls under 4A, and MPPT still in absorption. Then, when I come home and using the energy, it goes back to bulk if the sun is going down. Or if I'm not using Power, the MPPT going straight from Absortion to off.

2 Days ago it once was in float for 20 Minutes then the Sun gone down.


I think it is not good for the battery if it's continuing this. Does someone know an answer to this?

MultiPlus-II GX - Output "Dip" after battery charge

I have a new MultiPlus-II GX with a Hubble AM-2 5.5kW battery installed for 3 weeks now.
The output of the unit feeds a 3kVA APC UPS loaded at about 1kW.

Every time the battery charging current goes below two(2) amps after the battery was charged or top-up, the output voltage and current drop "Spike" - 97Vac and 0.9A - 230Vac and 3.7A is the normal running values, so low that MY APC UPS has to go onto battery to keep my servers running.
See attached image.

Any idea where we can start to look why the output dips?

MMPT RS 450/100, MP2 and Fronius

Hello to all,


I had the following “On grid” configuration:

  • 1 Fronius Symo 10.0.3
  • 1 Multiplus 2 GX - 5000/48 “hooked” on phase 1
  • 1 three phases Smartmeter
  • 1 Smartshunt 500/50ma
  • 220 Ah Li Ion batteries
  • 18 solar panels 370 wh each in two strings – 10 on one string and 8 o the other. (intention is to install another 10 panels)


As this year the grid electricity starts dropping every week (they are replacing the old network) I decided to get an MPPT 450/100 to make it work in parallel (Off-grid during the electricity outages) therefore I disconnect the 8 panels string from Fronius and I connected it to the MPPT.

MPPT and Smartshunt are connected to the MP2 via VE.Direct.


The main issues are as you can see in the prinscreen of VRM or console:

  • When there is a high load, the system is getting the power from the batteries and the MPPT goes to 0
  • Is throttling the Fronius inverted to 50-60% of normal production and is getting the difference from grid.

[image]

[image]

The funny part is that if I am connecting to the MPPT via Bluetooth or in the console and I am looking for the production of MPPT is shows about the right amount but somehow this is not showed in the VRM neither console Pages. I have no idea which ones are the right values.

What victron charger for lifepo4 + lead/agm? + Argofet question.

I am planning to upgrade the 12v house bank in my boat to lithium. In the process I need a new 230v charger, with 3 outputs to charge this new lithium bank, plus agm starter batteries, plus windlass/thruster battery.

looking for high capacity as well as keeping it on more or less constantly to maintain and keep all batteries topped up and in good shape.

the Skylla 12/70-3 was recommended to me but then I was warned that it would not cope with batteries of a different type.

Also, I already have the Argofet 200-3 mounted, and it works great. But again, someone said it would not work with one battery bank being lithium. As that bank is so power hungry the theory is that no charging current from the engine will reach the two other banks until the lithium bank is full.

Is it true? Or will it work? This lithium upgrade is turning into a headache before it started.

Cerbo GX connection to multiple MPPT not parallel

Hello everyone, I am almost confuse about to monitoring 3 MPPT Smartolar charge controllers that we are going to connect to the Cerbo GX. Because the solar installation is more than 20 years old, "unfortunately" we have 3 string of solar panels connected with 3 battery banks and after by schottky diodes to the load (MM.WW. system), but we can´t optimize the banks because the space of each one is limited to joint them on one battery bank. for that reason we should monitor each MPPT Charge controller separately. Is it possible to monitor each MPPT (PV power, BAT power and load consume) or each MPPT should be connected to a GX device?.

Thanks for your support.

Multiplus II Questions - Humming and adding power with other inverter

Hi. I am the lucky new owner of a Multiplus-II 24/3000-70/32. Just installed it and started using it. I have two questions, the first purely informative and the second more practical.

1. It's humming loudly (relatively). The less load on the inverter the louder. As I go long days with low loads (50-250W) it seems that it will be humming a lot under my ownership. I'm just thinking - sound means vibration and vibration means wear. How will all the solder joints, capacitors and everything hold up with that constant vibration. Maybe I am just paranoid but no other inverter I have used before have had that kind of hum constantly. Can someone put my mind to ease about this and explain if it is just the way they are designed and that it is ok, or otherwise?

2. I have PowerAssist in this inverter which is supposed to combine the inverter ac current with incoming current from the grid or genset if needed upon high enough demand. I have a 900W 24V sine wave inverter from another brand laying around. I wonder if, in the situation I needed it, I can connect that other inverter to the battery pack and feed it into the multiplus to get 2400+900=3300W? Is that a dumb idea or a reasonable thing to do in a pinch?

BMS 12/200 'Output on LED' won't turn green

7564-bms12200shunt.png


Hello everybody,

I am a bit of a beginner in all of this electric wiring, so forgive me if I dont use the right terms etc.


I recentlly got myself a 90Ah Victron Life4po Battery, the victron BMS 12/200, bmv 712 and a 100 watt solar panel with mppt 75/15 module.


I did all the wiring as shown in the graphic. The setup is used in an old mercedes 307D van and I wanted to use it seperately from the starter battery and alternator. I was a bit worried that my alternator could be to weak (it only delivers 55A) to permantly charge the lithium battery and I am only using the van in summer when sunlight is not an issue for charging.

So I connected the mppt minus to the Load Minus of the BMS and the mppt plus cable to the plus of the battery. The bms charge led is green with this setting and the bmv shows some Ah which have been generated by the solar system.

So far so good, but once I connect electrical consumers there seems to be an issue. For instance I connected a 12V USB charging station, the plus cable to the plus of the battery and minus to the LB Load minus. Now, my phone will charge but the current seems to switch on and of all the time. The "Output on LED" of the BMS is not green ( dont know if thats the issue) and in the bmv it is not shown that current is drawn from the battery.

As a Newbie to electrics I am unsure what else I could check or how to trace the error. I also tried to connect a compressor fridge likewise. The display will turn on but the compressor doesn t start.

I would really apreciate any hint on what to do in order to find a solution.
