How to Limit DC-DC Charger Current on Orion-Tr Smart?

Hey Victron community!


First time posting here, so forgive me if I'm missing any formalities.


I recently bought a Victron Orion-Tr Smart DC-DC Charger Non-Isolated 12/12-30. We are planning to use the charger in a travel trailer with a custom 300ah battery bank. The problem is that we want to wait to upgrade the OEM positive wire from the tow vehicle's battery (it is currently a 10awg wire) to a much larger wire until after we start using the trailer. Per my research, we will need closer to a 2awg wire, which is much bigger and a pain to re-route from the tow vehicle, so hoping to kick the can down the road a little.


With that said, is there a way to limit either max current or max power output on these units? Or is the only way to limit it via limiting the voltage? Are there any tricks to artificially limit the current?


Thanks in advance!

Multiplus 24/5000/120 settings: search mode, max charge current, input current limit

Hi,

I have the above Multiplus, BlueSolar MPPT 100/30, 2x200W/12V serial PVs, 2x200Ah/12V serial AGM batteries, Honda EU2200i generator and have the following questions about three settings:

1. If I have both the search mode and AES switched on, which is over-riding the other or can they work together?

1. For the 400Ah/24V battery set it doesn’t seem possible to set the maximum charge current as low as the generators continuous output 1800W/230V=7,8A. The lowest setting is 25% of something (percentage of what is still unclear? Maybe 100A x 25% = 25A?).

3. The input current limit can only be set to the following values:6,3A (1.4kVA at 230V),10A (2.3kVA at 230V),12A (2.8kVA at 230V),16A (3.7kVA at 230V),20A (4.6kVA at 230V), 25A (5.7kVA at 230V),30A (6.9kVA at 230V), 50A (11.5kVA at 230V). The question is how this setting affects the charging on different loads. It is clear that I should not have this setting to more than the generator’s continuous output power. But is it so, that 1) at no load the genset is charging with current of the setting (e.g. 6,3A), 2) when there is load up until the setting (6,3A), the load will be supplied 100% by the genset and the rest is used for charging and 3) when the limit setting (6,3A) is passed then the load will be covered by the genset AND the batteries and no charging will happen?


Thx.

DVCC doesn't seems to work?

Hello again.

I'm a bit confused with DVCC function.

I've charged my batteries to 100% today, which triggered BMS to stop further charge, but Multi is not stopping, DVCC setting is enabled, BMS is sending all limits to VenusGX correctly, but it looks like Multi is just ignoring it. My DVCC settings are as below:

[image]

Battery is 100% charged, BMS set the charge current limit to 0.0A, but multi is still pushing nearly 1A into the batteries:

[image]

My system is VenuxGX (with ESS Assistant) + Multiplus II 48V/3000VA + AC coupled PV + Liion batteries with Batrium BMS (connected to VenusGX via CANBus)

I've also noticed that the same thing is happening when BMS is forcing limited charging mode (battery nearly full, CCL set to 0.5A), the Multi also is not limiting power to the set current:

[image]


Is that normal??? Am I missing something? Shouldn't Multi limit the power to the set value or I just misunderstood this function?!

Blue solar 75/15 charge limit

I want to use a blue solar 75/15 to power a load at a max current of 10 amps, ie constant voltage. Ideally don’t want it to charge my battery with the unused power as that is dealt with by a different, bigger blue solar Array. The load will not always be as much as the power available, array is only 100 w, ie not enough for 10 amps..... although I could add a second 100w.......
basically it will be connected to an elec distribution board, that powers all the loads and has its own battery charge algorithim. It also has a display showing all battery voltages/solar currents etc, so I wanted to use it to control and display that stuff and charge the battery.
so, if I connect the load only to the 12v distribution board will that do the above, or does the battery connection also need to be used. I assume turning charge off stops all power, as limiting charge current limits charge and load?

Or any other ideas?

SmartSolar MPPT 100/20 turning the load "On" then "Off" then back "On".

I purchased a Victron SmartSolar MPPT 100/20 Charge Controller. I am having a problem with the charge controller cycling the load "On" then "Off" then back "On".


Description of failure:

1. The charge controller will show that the load is set to "On".

2. A 12v fan is connected that draws a max of 9W of power or a car cell phone charger is plugged in (without the phone connected or charging)

3. The charger controller will show that the load is turned to "Off"

4. Have a pause for 1 to 2 seconds

5. The load will then be turned to "On"


Notes: The charge controller never shows a voltage below 12.6 volts from the battery so I know that it is not pulling a large load from the battery.


I don't see how a 12v phone charger without a phone connected could be tripping the 20A capacity of the controller.

Load output inrush current HW fix availability for Bluesolar 75/15

Hello @mvader (Victron Energy),

AC input current limit setting is very different from where it actually limits.

Got a Quattro 12/5000/220-2x100 120V running firmware 2733430. (Same system as in this old post.) Since then, I've beefed up the shoreline to a true 20A circuit, and adjusted the input limit to 20A accordingly.

Sometimes the system will happily draw 19.8A from the shore, and sometimes it'll limit itself at 11.6A and go into PowerAssist for my roughly-2kW load.

Here's the weird thing: If I increment the input current limit just a little, the actual power drawn from the shore increases dramatically. Here's my observational data:

Current limit set in VEConfigure Actual current drawn Load and status
20A 11.6A 2kw, PowerAssist assisting
21A 12.6A 2kw, PowerAssist assisting
21.5A 20.2A 2kw, battery charging
22A 20.7A 2kw, battery charging
30A 27A 2kw, battery charging


AC input voltage is roughly 108-112V in all cases.

So why the huge jump in actual current, for a tiny bump in the set limit? It's not correlated with input voltage, and I can't identify anything this behavior is correlated with. I've tried setting WeakAC and it had no effect on the behavior either way. Shore power is 60Hz grid AC, so it's not like a generator is lagging its frequency or anything. What else should I be checking?

For the moment, I'm leaving it at 21.5A to keep the battery from draining while on shore power, even though it slightly overdraws the circuit's nominal rating, the breaker doesn't actually trip until a bit higher than that. ;)

Sustain current too high?

Hello Victron fellows,


I have set some Li ion with Victron inverters, always for self consumption with PV inverters, but this one is cracking me up. This system consists in three 48V Multiplus II 3000/35 as a three phasic system, and an ESS assistant is set. The sustain voltage is 43V and cuttoff around 42V. The modules have a low SOH, but the system should work anyway. It charges and discharges correctly, up to the point where my BMS disables allow to discharge at around 48V, because there are low cells (it should discharge to less than 42V if it was good).

Then, Sustain mode is active and the current goes UP TO 90A. Of course when this happens the voltage raises quickly, the allow to discharge comes on again and it goes to Discharging mode. Repeating the process endlessly - Even without PV POWER, that means it consumes a lot of power.

My question is, why does it go up to 90A, since sustain mode should be 5A per unit and how can I solve this?

Thank you very much!

Phoenix Multi Compact 12/800/35-16 Overload Warning and Low Battery Alarm

Dear all, we have recently bought a Multi compact 12/800VA together with a SB SUNLIGHT AccuForce 12V - 150Ah Solar VRLA Battery in order to replace an ONLINE UPS in a on-Grid Photovoltaic 500kWp installation. The system works in 12V mode. The inverter charger is connected to the AC grid and the only load is the Protection Relay (SEPAM) from Schneider Electric installed on the Medium Voltage Switchgears Board. The charging mode is 99% in "Storage" mode cause the load is very little. The problem we are facing is that after two or three days of operating the Inverter goes to fault mode and the alarms we got is overload and today together with a Low Battery Alarm and the PV station goes out of the Grid. The only thing we do when the fault comes is to go and turn off and on the inverter/charger and the problem is (temporary) solved. Today the fault happened, we got a "grid lost" e-mail message, when we reached the inverter the fault was gone (only the green light when on), as it seems the inverter was inverting. We turned off and on the inverter and the inverter "saw" again the AC grid.

Since we bought the inverter we did not do any optimizations or changed any settings for example for the current output (everything is as it came from the distributor). The system also has a Color Control GX and we can monitor the system from the VRM Portal. Please see attached pictures, videos. Any ideas for the fault or settings needed are much appreciated! No clue why thr fault takes place, on the other hand the overload maybe comes because the SEPAM maybe draws a lot of current in order to power the motorized central medium voltage circuit breaker.20200316 Status Monitoring2.jpgfaults.jpginput current limit.jpgMV SEPAM.jpgBattery.jpgGrid connection restore.mp4

Solarcharger and it's max PV current (oversizing PV-Array)

Hi Guys, I am new on this forum, but I would love to get some clarification regarding the maximum currents which may flow at the PV-array. I have looked around this forum, but I did not find a proper answer till know, with a clear explanation WHY/ HOW the MPPT is limiting currents...

another discussions around this topic is for instance: smartsolar-maximum-input-current

To be clear, we All know and accept that the Voltage limit (Voc) shall never be higher than the MPPT allows...


The questions comes from the manuals/ Data-sheets which list 2 different footnotes...

@ Manual:

Footnote 2): A higher short circuit current may damage the controller in case of reverse polarity connection of the PV array.

[image]

@ Datasheet:

Footnote 2): A PV array with a higher short circuit current may damage the controller"

[image]


And generally speaking people tell me that the PV-currents like Isc, may never be able to be higher than the rated current of the Solarcharger at it's PV-side. BUT, if I read the footnotes from both Manual and Data-sheet I get confused, and would like to better understand why Victron is writing this.

For me are these SolarChargers smart devices which can control Voltage and currents very well. It is for instance possible to lower the charge current by changing it's settings via the app. Why would then oversizing a PV-array (with e.g. a SmartSolar 75/15) with respect to Isc be dangerous for the device? If I would hook 2x 60cell PV-panels in parrallel for instance, theoreticlly a Isc of around 20A could occur.. But to my opinion this Isc Current will never occur within the solarcharger because it is searching for it's MPP. On the other hand Impp could theoretically still be higher than 15Amps, like around 17Amps which would be too high as well. BUT, Is this device not able to limit its input current (in this case max. 15Amps) by deviating from it's MPP working point (like lower it's Amps by increasing the Voltage to Ioc)??

[image]


I downloaded version 06 of following Manual https://www.victronenergy.nl/upload/documents/Manual-BlueSolar-charge-controller-MPPT-75-10-75-15--100-15-EN-NL-FR-DE-ES-SE.pdf:

No Load output current sensing

[image]


Hi all,

We are employing the SmartSolar MPPT 75/15 in a number of remotely located instrument cabinets that will eventually be inaccessible to people. To remotely monitor the SmartSolar device, we are utilizing a Serial to Ethernet bridge. This device also allows us to also perform any mandatory firmware updates remotely, but with a caveat.

In order for us to be able to take advantage of the SmartSolar’s load current sensing, our load (‘Ethernet Devices’) needs to be connected to the LOAD output. However, during a firmware update, the LOAD output switches off at the 4% mark, thereby causing the firmware update to stop indefinitely. D1 solves this issue by sourcing power directly from the battery (Batt) when the LOAD output switches off (during a firmware update). The side effect of connecting the Batt terminal to the LOAD via D1 is that the LOAD output never comes back on, despite VictronConnect stating that the LOAD is ON. Instead current continues to flow through D1, therefore current sensing on the LOAD terminal never takes place. Only by utilizing D2 does the load current flow through the LOAD terminal and reported in VictronConnect.

Our question: Before we invest time in building a low-power-loss device (FET in place of D2) to circumvent this issue, is Victron able to provide a firmware update that ensures that either the SmartSolar LOAD output always stays on during a firmware update, or at least a firmware update that would allows us to omit D2? And failing a response here, how can we contact Victron directly with this request?

Thanks in advance,


Michael

AC Current Limit when using ESS as a grid parallel system

I have a Multiplus II GX system which is installed with the ESS application. It's connected to the UK grid via a single phase 100A supply, connected to AC IN of the Multiplus.

All loads and an AC coupled solar inverter are also connected to AC IN of the Multiplus.

The Multiplus is able to balance the grid supply close to zero, charging the batteries off of solar and discharging them as required. I also have time of use tariff which enables the Multiplus to charge the batteries over night.

The issue I have is that I run a lot of loads over night in the cheap period of my tariff including a 32A electric car charger. This regularly take my load over 50A.

The Multiplus needlessly regulates its own charger down in this period and on occasion supplements my grid supply from batteries. This is needless and results in me not having a full battery bank at the end of the cheap time-of-use period.

I can't increase the current limit beyond 50A on the Multiplus or seem to disable it. It is not needed in a parallel grid connection as I have it, as far as I can see.

Can somebody advise me as to whether I have missed a setting or if this is something Victron need to consider in a future firmware update. I want to be able to heat my water, charge my car, batter bank, run my dish and clothes washers during my off peak period!
