charger

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!

Hi,

I found a Phoenix Multiplus second hand for a decent price. Will I be able to properly charge my LiFePo4 batteries with it? I just realized that it is an older inverter/charger — can I manually set my charging profile?

Thanks!

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).

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.

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?

I have a 200w solar panel connected to my pwm light 12v 20a and it was working fine. The light was flashing indicating power coming from the solar panel and into the battery but now the solar input light is showing nothing even though I know there is 19v coming from the solar panel. At one point the battery did run flat and I thought maybe it turned itself off so I disconnected it and reconnected the cables and still nothing. When change the setting I get an 'ff' flash after the setting has been selected. Not sure what this means as it is not in my one page instruction sheet I got with the controller.

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,

I have a Multiplus 48|3000|35 with a PowerPlus Eco LFP battery. This battery has its own built-in circuit breaker and internal BMS. The battery BMS provides a NC dry contact when all is well. A BMS alarm of any sort (low/high voltage, fault current, temperature, circuit breaker trip, etc) will open the NC contact.

I am using the Multiplus "Two signal BMS" assistant (single contact for high/low) to control what happens if the battery BMS contact opens. My current (preferred) setting is to "switch to float" rather than "bypass" because I think it would be safe under most conditions. And, if the BMS cable was removed or faulty at least the battery would be on float charge.

My concern is that if the BMS alarm was cause by the battery circuit breaker tripping the Multiplus would be float charging to no battery load. Is there any problem with the Multiplus being in float charge mode with no battery?

Is anyone using the Phoenix 12/50 charger for Smart Lithium. I am building a system for my rv and the dealer says it is incompatible and recommends the SkyIIa IP44 charger. The SkyIIa will not fit in the space I need it to. The Phoenix charger will work fine for the space. It is my understanding that the Phoenix charger has adjustable Voltage via a computer interface through ve configure and a MK2-usb dongle. I would be using a smart battery protect to disconnect the charger from over voltage via a mini bms.

Thanks

Hi - I just got the Blue Smart IP67 charger. It states that for Lithium-ion batteries, the charging voltage is 14.2V, and float is 13.5V. My batteries are rated differently: 14.6V/13.8V. Is there a way to reconfigure the charger with the proper voltage? I couldn't find such option in the app. Appreciate any help!

I have x8 Trojan T-105 wired series/parallel to a single 12volt house bank.

Can I parallel both charging banks of the Phoenix 12/50 charger to a single battery bank to provide 100amps of charge?

Will I loose any functionality? Is there a downside to doing this?

If not, then I am limited to only 50amps of charging.

I have a BlueSolar charge controller MPPT 75/15 that is causing interference. When the Blue Solar charger function is enabled and it is day time, it is creating interference with a car radio installed some distance away and is making the radio impossible to listen to. When the Blue Solar charger is disabled (through Victrom app) or when night falls, the interference stops. I am looking for advice on the best method to substantially reduce the noise coming from the BlueSolar charge controller MPPT 75/15.

Hi

We have a 12v / 415AH off grid setup with solar (1KW + Victron MPPT 150/50). We are not getting enough sun (barely any actually). So we are running a small 2KW generator for about 10 hours with a Victron 30Amp charger from time to time to try and fully charge the batteries. However for some reason we never seem to be getting the charge up to 13v (or even above our 70% / 12.3v level). You can see from the data when we run the charge (5 July, 12 July, 19 July) the min voltage is stepping up but it's not getting to where it should be (running 10 hours at 30amps should give us 300 amps which should be well north of 12v. We are not running the power on the charging days so we cant figure out what's going on. Any ideas?

I have a Phoenix Charger 12V/30A, but when I plug it in nothing happens...

No led burning/flashing

I do measure 230V on AC input and the fuse seems to be fine.

Anything else I can try?

Greetings to all.

I have on board a Victron Centaur 24v/80A charger charging a bank of 2x2 12V/225Ah lead acid batteries. Recently the batteries started to heat and loose water, when I went to diagnose I found out that the charger is outputting 29.8V regardless of dip switch setting. I found that there is a potentiometer inside and tried adjusting that but I could only reduce the voltage to 29.6V with strange pulsing noise from internal SMPS like it is running on minimum pulsing. I cannot leave the charger like this,it will destroy the batteries. Did someone encounter a similar problem? Is there a solution or should I just buy another charger? This one is about 4yrs old so if its gone already I think I will consider another brand. The one I replaced lasted over 12 yrs. Oh,I tried replacing the batteries with another bank new batteries but the charger is still outputting 29.6V.

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 ?

I am looking at implementing an 'intelligent' energy harvesting system using a recently installed system that has PV array and a Pylontech battery bank and the above plus a mppt 150/70, that is to use a certain/calculated amount of stored energy in the evenings, and then restore that with PV sourced electricity via the mppt 150/70 the next day. I have made a seperate contoller to do this, that can monitor the SOC from the Pylontech bank via CAN Bus messages, so that once the SOC quota is used it will go back to AC power. I will activate the Inverter by an external transfer switch to disable the AC in and that will get the Inverter on line.

What I don't want the Inverter / Charger to do is use the main supply to charge the batteries automatically when it comes on again, that will be done by the PV the next day, I know one can switch off "Enable Charger" in the VE Configure but I want to be able to do this via a control signal or software command to the Venus or the Quattro everyday and can't seem to find any way of doing that so far.

I would appreciate any information in this regard.

One way of doing this is to switch OFF the Inverter by the remote control which is easily done but then there would be gaps in the data on the VRM portal since the Quattro monitors the main feed in terms of power supply.

Thanks in advance.

Settings for 100/50MPPT

I have a MPPT 100/50 connected to one Renogy 200ah Deep cycle Pure Gel Battery. I need the correct settings for the rotary switch. The controller is connected to 4X100W solar cells which are connected in parallel. Would appreciate any help. Thanks in advance

Hi All,

I have 100/20 Blue Solar Charger and wondered if I can use the +ve load output to power the loads whilst leaving the -ve load output terminal unconnected and instead returning the loads directly to the battery?

Is there a reason why the loads have to be returned via the -ve load terminal or is this just provided for convenience?

Thanks,

Richard.

I have calculated the difference between grid and charger supply and it seems that only 20% of the demand comes from the charger and the rest from the grid irrelevant of the demand.is this die to settings or can you suggest how this can be fixed?

Thank you

I have a Victron Phoenix Multi Plus 24/3000/70 charger/inverter on my European boat which was installed in France around 2009. The data sheet states that the charger only has an input frequency range of between 45-55hz. However the manual also states that the product can operate at 50hz or 60hz. Can anyone please confirm if the charger will work ok if i plug it into a shore supply in the US of 220v at 60hz? I don't mind if it passes through 60hz but i want to be sure that it wont blow up the charger.

I want to buy a IP67 12/17 or IP65 15A charger for permanent installation on my boat with 165A AGM battery.

The IP67 is better protected, a little bit cheaper and has 2A more power. Other features look identical. So why are there two different model lines? What are the advantages of the IP65?

Hi,

what voltage does the Blue Smart Charger range supply when in power supply mode?

thanks

I have a tystor soft 1210 charger connected to a septer 1275 charging powerbank + starter battery on my boat. My engine generator also charges through the septor when running.

When my engine is running, I can monitor the power going into the battery, but not when charging from the tystor.

Also, when my battery bank is fully charged, and the tystor is active, the tystor acts as powersource (And keeps the batteries topped off), however, the BMW deducts the amps (even though voltage is maintained) from bank and SOC.

Can i fix this somehow, or just learn to live with it and manually set charge to 100% when cutting the tystor?

Regarding SmartSolar controllers, the battery setting Charger enabled says to only use in maintenance mode. I realize solar and shore power charging can coexist but would it hurt anything to shut down solar charging via this setting so that only shore power charging is being applied to batts?

I plan on using two 24/40 Phoenix chargers to charge my Tesla Model S Modules (3) 24v batteries. The batteries should never be charged above 25.2 volts, however the selectable settings for the phoenix chargers are all over 28 volts. How else can I control the voltage levels that these chargers will charge my battery to?

I will also have two inverters running (230v 24/5000 and a 110v 24/3000) but they will not use their charging side because I'll only be using them in inverter mode, due to differences in frequency (50hz on boat, 60hz on shore power). I'll also have a BMV-712 installed as well.

Thanks for any help.

Hi,

Can anyone tell me what the internal dip switches should be set to on the blue power charger 12/25?

Thanks!

This system is in an RV (caravan). Victron Energy equipment includes SmartSolar MPPT 100/50, MPPT Control, BMV-712, VictronConnect App. Batteries at 100% SOC, 1.81A load, 600W solar array. It seems the controller has difficulty providing only the 1.8 amps drawn by the load steady state when the batteries are floated and not drawing any current. In this case, the solar controller stops supplying current, the battery drives the load, and then the solar controller pulses a bunch of current back into the battery to replace the charge used. Then stops, letting the battery continue to drive the load. This happens every few seconds. Charge current is steady when batteries are less than 100%. Here is a link to a video showing this MPPT 100/50 behavior

Hi everyone,

I’ using the IP22 charger as power supply.

Is it correct that the charger make again the step charge sequence, absorption-float-storage, when I plug in it.
