charger

Hello Everyone,

I was bench testing a Multi 24/500/10 before I deployed it and I have noticed something very odd.

With the AC IN connected to the grid if you press/touch the front of the multi especially on the edge of the casing, even with the lightest of pressure the transfer switch opens and the Multi switches to inverting. After 10 seconds or so the Multi reconnects to the grid.

It looks like something is not quite right inside. There is no visible movement in the case when you press it but it must be enough to open a dry solder joint or something similar.

I have never had to RMA a victron product but unless I am wrong I will have to contact the dealer.

Has anyone else seen this behaviour?

Hello guy's

I've got an issue with an old Phoenix Multiplus compact 12/2000/80 on firmware 1871148.hex ...

My problem is that the value for the low level battery is at 12.4v and it turn off inverter at 12.3V ...

And the second issue is that the charger don't want to be turned on even if its plugged on a generator ( i try 1000w and 2000w generator) and not even when i plug it on the grid ... when i turn the multiplus on charger only i can hear a "Clac" in it, but doesn't work anyway ...

So i almost buy the MK3 Pc ve.bus to change the settings and maybe see if the problem came with some wrong value in it =)

But i read on some victron page that this 1871148 firmware has no Ve.bus (and my pcm have only one rs485 connector that proove that my multiplus has no Ve.Bus)

So can i upagrade it any way ? the Mk3 can work or maybe i read somewhere that i can try with the old Mk2 ? but its a lil bit expansive and i can't buy the two just for a try ^^'

Do you have some ideas why the charger dont want to turn on even on the grid ? or ideas for the limit value of the inverter ?

Thanx for helping me guys and sorry for my approximate english, i'm french ! ;)

Hi, I have a blue smart IP22 charger 12v/30a.

The charger isn't showing any signs of voltage, and it does not charge my battery. When plugged into the mains power, the charger starts up, and I can connect to it via Bluetooth. Just no dc power output.

I've tried a few different cables, no dice.

I tried to take out the fuse by just pulling it, no dice.

I tried to unscrew the screws next to the fuse blade that I thought was holding the fuse in, the screws just spin in its place and not actually coming out. No dice.

What do I do to actually replace the fuse, or know anything else to try?

A forced update to 3.12 has rendered the charger dead. The update will get between 75% and 86% then a B10 timeout error is encountered. Distance is not an issue, I am about 5 feet away.
I am not able to find an older firmware version to load.
How can I load the new firmware?

Current version: none
New version: v3.13
Android device.

Hi together,

I have a question concerning using a BatteryProtect (BP) to disconnect the charge source in a Lithium Battery System with VE.bus bms.

In the BP manual Figure 5 illustrates how to connect the BP for charging situation and it states that "uncontrolled reverse current will flow through a Battery Protect if Vout > Vin."

Now I wonder what happens, when the Voltage of the charger (Vin) drops, i.e. Solar charger when there is no sun or any other charging source that is swithched of. Wouldn't then the Voltage of the Battery (Vout) be higher and thus reverse current flow causing danger?

THanks a lot for your comments, I am abit affraid of burning down my RV...

cheers, Daniel

Hi folks,

Does anyone out there know the voodoo behind the charging algorithm or what, other than temperature, could be causing Quattros and MultiPlus's to not reach their maximum charging currents?

Problem

The inverter/chargers are not reaching their maximum charge rate. A cluster of 6 x Quattro 15000 can theoretically push 1200A. There are 45 flow batteries which can each accept up to 50A during charge.

However, test results on this system showed a maximum of 1050A reached which after 5 minutes reduces to 900A which is then sustained. This is only 150A per Quattro. This results in 9 hours to charge rather than 6 hours which should be possible. This impacts the business case for some clients. This was the same on both a 35 degree day and an 18 degree day (Celcius).

The system is running the ESS module. The tester commented that charging fewer batteries and/or with ESS not running he has observed the 200A charging on other systems, but for some reason, it has not been able to be reached in this system.

Ideas

The comparatively high internal impedance of the flow battery being 80 to 100 milliohms (all connected in parallel) may be causing the algorithm to not adjust the voltage high enough to push enough current into the batteries.

What does the "lithium batteries" checkbox in the charger page actually do/change? Again, I imagine this would change some characteristics of the charging algorithm, even if lithium battery is not chosen from the list of battery defaults. Li

Questions

How does the charging algorithm work for the charger in Multiplus II and Quattros?

Is it possible that the charging algorithm would not raise voltage enough either due to high impedance?

or the ESS module somehow altering behaviour?

Phoenix Smart IP43 Charger no Smart Battery Sense function.

When will the Smart Battery Sense function be added? in the Phoenix Smart IP43 Charger

Can the Victron Pheonix Smart IP43 charger connect to and use a battery temperature sensor?

I know there's a similar question out there but an answer has been added to that question which really isn't an answer and the question has been ignored for months.

I have a Victron Quattro in my grid tie in system in which is also a Fronius 8kva Solar Inverter feeding an 800ah battery bank and a 13 kva generator. A Color GX allows online monitoring and control of the system.

The problem I have observed is that my Victron Quattro does not charge my batteries at the maximum amps possible (DC 140 amps) when it can. The maximum I have observed (during bulk and absorption charge states) is 80 amps. This happens no irrespective of the mains supplier (Grid or Gen). On VEConfic "General" tab, I have set my "Shore limit on AC 1 (grid) and AC 2 (gen) to over 60 amps and 55 amps respectively which is more that sufficient to meet the charger's demands.On the "Charger" tab, the charge current is also set to 140 amps. I have the ESS assistant running because i don't want any Feed in to grid when the PV is running. Any help would be appreciated. Thank you.

We are taking our 220v yacht from Europe to the USA this winter. I appreciate that the USA is 60Hz and Europe is 50Hz. Having checked our equipment it will all work on the different frequency - but needs 240V. Which Victron product is best to convert the voltage?

Hi

i running a ESS (MultiGrid 48/3000 FW459, VenusGX FW v2.31with EM24) with AC Coupled third party PV Inverters (via ET340 and ET112) and a Smart Solar 150/35 v1.39 and a BYD B-Box 5.0kWh. (DVCC enabled, SVS disable, Smartsolar has BMS controlled)

The DC Coupled PV system is oriented south and could be enlarged by approx 900 Wp, since currently only 1,8kWp is installed. Maximum charge power to battery is limited at 2000W fixed due to the 35 Amps - i know ;).

In the ESS Settings I enable " Feed-in excess solar charger power" but soon i discovered the the typical behavior of the system was to charge from the East oriented AC Coupled inverters, which means, the the battery is full, sincce there is enough excess. But the south orientated DC coupled PV System was dearted by over 50% due to battery being at SOC 100%, even with the enable option of "feedin excess DC Power". Over have of the production of the south oriented DC coupled PV is derated (see pic attached, redline is potential solar production).

[image]

To prove my hypotheses i changed the ESS Setpoint to activly discharge the battery into the grid, thus a lower SOC than 100% is realized. this enables the BMS controlled Smart Solar to use the full potential of the PV system. (previously 340W production goes up to 900W Production).

See my screenshots and notes

ESS Feed-in excess solar charger power - not full potenial.pdf

Conclusion:

I presume that the Mutligrid doesnt discharge/feedin as much power as the full potential of solar available on the DC side.

I would presume that the voltage Gap between SmartSolar and Multiplus isn't high enough for Multi to discharge the battery more but to keep it at 100% and though making it possible for the SmartSolar to feedin more of his potential solar power.

So propably i will not add any more Modules to the Smart Solar or install another SmartSolar, but install another PV Inverter AC coupled.

If anybody has the same Issue please let me know!

If anybody has an idea how to optimize the use of the DC coupled Solar to feed into the grid, please let me know! I thought already of an external PLC writing the ESS Setpoint into the Modbus register, to actively reduce the SOC during the daytime, to make more use of the DC coupled PV System.

I currently have 2 x 265W solar panels connected in series to a Victron MPPT 100/50 Charge Controller which is connected to 2 x LiFePO4 138W batteries connected in parallel. I also have a BMV-712 to keep an eye on things.

My next step is to add in a means of charging the batteries from the vehicle alternator (180A, non-smart alternator), so I'm looking for a DC-DC charger and I'm hearing rumours of a new Victron Smart DC-DC charger about to be launched.

I would also want a means of keeping my vehicle's starter battery topped up from the solar system. Will this new charger be suitable for my needs?

Hi I am looking to buy blue smart charger for my lithium batteries that I can also change to jel . I need a price I also need to know how much it would cost for Delivery to northern Ireland

hello

i am looking for a Victron Product that could handle the Charging of my batteries of my truck Camper went driving. I found this product Sterling Battery-to-Battery Charger | 12V In - 12V Out | 30 Amp Input but would like to stay with Victron ...for a better monitoring and integration with my system.

I have a Blue Power IP20 Charger where the fan no longer comes on. Is this repairable or do I have to get a new Charger?

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.

I have a Quattro 24/5000/120 connected to a pair of 12V lithium batteries in series, with a BMV 712 monitoring them.

I usually don’t allow a full absorption cycle to run, but the last few days I’ve let it complete the cycle to resync everything. And I’ve actually left the system to manage the batteries as “normal” allowing it to keep them full. It’s been “short cycling” the recharge as the batteries are mostly full, but discharge slightly over float then restarts the bulk cycle.

Since then, I’ve noticed my battery BMS throwing a high voltage alarm and I traced it down to my Quattro sending over 30 volts to my batteries!!

How can this happen?

My absorption voltage is set to 28.4 and float is 27.2.

This appears to happen just as it’s switching from bulk to absorption. It happens pretty fast and sometimes VRM doesn’t even catch it. This time it did.

Is this normal?

This is quite concerning since that voltage is way too high for these batteries.

Hi,

I have a small 24V system with two 12V batteries in series that I need a new charger for. Can I charge these with 2 separate Blue Power or Blue Smart IP22 12V chargers, one connected directly to each battery? If these chargers somehow connect the - with PE or N this would of course be a bad idea as it would cause a short circuit.

I have some constraints on available items in stock locally and time to get deliveries through customs etc. before I want to leave, thus looking for an un-orthodox solution.

My Blue Smart IP22 charger (12 V / 30 A - 3 outputs) sometimes trips the automatic fuse of the shore supply when starting up. The fuse is 10 A , B-curve type. No other equipment than the charger is connected at that moment so the charger must be the cause of this. When the charger does not trip the fuse, it functions normally.
What could be the cause ? Is this a known issue ? Any suggestions for a solution ?

Hi all,

I just got an MPPT SmartSolar Charge Controller, which I'll connect to my PV panels and lithium batteries. I will also connect a load in the load output of the charge controller.

I would like to know if it is possible to program the SmartSolar to direct the power from the batteries into the load when the PV power is low.

Thank you!

Hello,

actuall my consumers are direct connected to the battery, not using the "load" from the charger.

Now I will change my cables and connect the consumer to the charger to see the consumptions etc.

Question:
Where is the measure? Plus or minus?

I think, Plus or Minus (one of them) from Solar, Battery and Load will be connected together (have a direct electric connection). In my case I only have the need to change one wire (plus or minus) and bring this wire to chargers "Load" (and the other can be still direct connected with the battery (plus or minus). And mot both from my consumers ...

I only use my solar system during summer and I'd like to top my batteries off-season with a cheap method. I do not want to invest into another battery charger, so I figured maybe I could simply use the MPPT for this purpose.

I can see the Blue Smart in the app until it turns off. It shows the correct voltage, but 0 A current flow.

And I can repeat the process.

We have a Centaur charger (12v/20A) which has been running pretty much continuously for around 10 years. It is charging 1 single battery and one bank of 3. One of the 3 batteries in the bank of 3 suddenly exploded last night without warning.

I'm keen to make sure this has not been caused by a problem with the charger. What tests can be carried out on a Centaur charger to ensure everything is working correctly. I can't remember which distributor we bought it through

hi,

I 'm installed a set with BMS (Not victron, it is 123smart) for my lithium batteries and i connect it in quattro in the Lithium specific mode which use AUX1 to allow charge and TEMP1 to allow cischarge.

My problem even if i bought a lot of equipment (Venux, BMV712...) to command my Mppt solar (Victron 150/100) and the battery protect (BP65 used connect the 12V load) with the respectively ON/OFF remote of each equipments, i haven't found how connect the remote control of these equipements.

I found different possibilities but i'm not sure :

- Program K1 relay of quattro to close it 10s after the activate of AUX1 of quattro (Aux1 input is activate by BMS to allow the charge) and connect this K1 relay on ON/OFF remote of MPPT. it enable the charge of mppt.

- Program K2 relay of quattro to close it 10s after the activate of TEMP1 of quattro (Temp1 is activate by BMS to allow the load - inverter of quattro) and connect this K2 relay on ON/OFF remote of battery protect. it enable the load (12V) through battery protect.

OR

Set, for MPPT and Battery Protect, the specific voltage of used.

What do you think about these solution and maybe have you another solution?

Where can I find Quattro 8000 24V 200/100/100 AC input wattage consumption for 230V connection. I read the manual but couldn't find it and calculating it doesn't seem right.

Hi,

These 4 parts were delivered with my Multiplus 12/800/35 inverter charger. Could anyone help me identify what they are for?

I believe the 4th item is the temperature sensor cable, but I have no clue about 1-3.

Thanks!
