charger

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

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).

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

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?

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.

Phoenix Smart IP43 Charger no Smart Battery Sense function.

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

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!

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!

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.

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?

Regards, Greg

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.
