charger

I just purchased a new Samsung a8 and am unable to connect to my 75/15 mppt controller and Bluetooth smart dongle. The dongle is not visible in the Victon connect app device list and does not appear when searching for Bluetooth devices

I can still connect using my old Samsung S5 phone and using my partners Samsung a5. I have updated the mppt and phone to the latest firmware but this did not solve the problem. the Samsung a8 connects to all of my other bluetooth devices such as my laptop, bluetooth speaker and other phone.

Any help would be appreciated

Hello, I built a powerwall for emergencies and to run an AC unit, and other electric gadgets, it has a 5KW capacity or close to that. I use the Victron's 150/35 Charge Controller with BT adapter, it is working great. The question I have is about the profile, for my batteries, during charging the app shows 41.5 volts at around 6-12 amps, then tappers down, before going to float, when I look at the history the battery max voltage shows around 42.60 volts, when I check the voltage at the batteries it shows it 41.5 volts, what could be the cause for the app to show a higher voltage than the batteries show at the terminals? i would like to set the charging to 90% of the battery capacity which should be around 41-41.5 volts, so should I trust the app reading versus the battery terminal reading? is there a modification to the profile that will correct that? Thanks

Hello!

I have MultiPlus Compact 24/2000 / 50-30. After installation everything was fine, but now I noticed the following: the switch is on (not charger only), and the MultiPlus Compact 24/2000. I did not find such mode in the documentation. What could it be?
Thanks!

I'm looking at buying a 12/25 IP67 Victron battery charger to run off a small ( 0.7kva) inverter generator, Specs of the Victron chargers do not show input watts or current. Ive already got what I believe is a quality switch mode battery charger ( NOT a Victrton) but after running it via an energy meter its power factor is poor , around 0.54 to 0.60 . It draws 2.2 amps at 240v to output 21 amps / 12 -14 volts DC .

The Victron specs say the IP 67 chargers ard 95% efficient and comply with the EU power factor standard EN61000 -3-2.

My guess the AC current draw should be around 1.7 amps @ 240v at full 25 amps output. Has anyone measured AC current input of these IP67 chargers before?

Been really happy with my small Victron solar controllers , 75/15 & 100/20 , so I'm hoping the quality, efficiency and ease of use via the app is the same for their battery chargers.

Hola,

Yesterday, I received a SmartSolar 100/50 charge controller ordered thru Amazon. It's to be installed in my RV. Going over the manual (version 02, Sept. 21st 2017), section 3.2 states 'The charger must not be connected with grounded PV arrays (one ground connection only)'. Does this mean I should not be grounding my solar panel frames to the RV chassis? My plan was to ground the solar panel frames to the RV frame in one location and ground the charge controller housing to the RV frame at another location. According to the statement in the manual, this should not be done. Please clarify the statement for me so I have a better understanding. Thank you for your time.

Kind regards,

Michael Bonnar

Your browser does not support HTML5 video.I just finished putting a Quattro with a Digital Multi Control GX panel. and all things worked fine yesterday. But today all the lamps and the inverter lamp are blinking, but only on the Digital Multi Control not on the Quattro 24/5000 some ideas of what it can be?

Hi, I have a 12v 45Ah AGM starter and a 12v 110Ah AGM cycle battery connected to my Blue Smart IP22 (3 outputs). The starter battery is always more or less full, but the cycle battery sometimes will go down to about 60% SOC. If I then connect shore power to the charger, it looks like it switches into float way too early, because of the already full starter battery and my BMV only shows float voltage for my cycle battery. So I assume I will not get charged properly, because float voltage is much lower than the needed abs voltage.

Or do I miss something?

Greetings!

I have installed on my sailboat a Multiplus Compact 12/2000. The AC shore power runs to the unit, and then out to the shipboard AC distribution panel. Everything works great, but...

Is it possible to override the charger function, so that when plugged into shore power you could run AC loads without the charger functioning? I have tried to set the shore power current limit to 0A through my Color Control GX, but it won't accept the change and sets it to 6 or 8A (can't remember which).

Thanks in advance,

Matt C.

I have the Multiplus 24/2000 with MPPT 100/50 and 6 panels on the roof.
Two new lead batteries each 280Ah.
If I let the charger run at 6 pm, switch to the inverter mode after 14 hours,
in completely bad weather, the BMV switches after about 8 hours (load was about 11A) (V <24.4) the multi with his relay in the network operation. Then the charge state is at 90%.
With an acid siphon, I also notice after fully charging that the batteries are not full at all.
I have 32qmm cable between battery and Multiplus.
What's wrong?

I'm a newbie to the fancy Smart controller that Victron provides, and I wonder if my charger readings and settings make sense. I'm also not real clear as to how the specs that Crown Battery provides correspond to the settings that Victron requires in their VictronConnect app.

From having read others' experience, I believe I have the settings right, but I'd like to understand their actual meaning!

My setup:

2-100W 12V solar panels in series

Victron Smartsolar 75/15 MPPT Bluetooth controller

Victron BVM-712 battery monitor plus temp sensor

2 Crown 220Ah GC2 6V standard FLA batteries in series

temperature 7°C

This is my understanding of the "bulk-absorption-float" cycle, please advise if I have it wrong...

Charging starts in Bulk mode, with max available current (up to 50A per Crown, but in reality current is limited by my panels to @ 13.2A)

The starting ''Voltage" in Bulk mode is determined by battery state of charge - and it gradually climbs to "Charged" level, which is equivalent to Absorption level (14.22V per Crown specs).

Once the SOC climbs to the "Charged" (Absorption) voltage-level, the controller switches to Absorption mode, which then limits the voltage to no more than the Absorption setting, and varies the current, gradually lowering the current, as the battery becomes more charged (as the battery accepts less and less). Question: does the controller actually keep the voltage at the 'Absorption' voltage-level (Crown calls it: 'Constant Voltage') during this Absorption phase?

When the charge current drops as low as 5A (per Crown specs) the controller should switch to Float mode (Crown: 'constant current'), and (should?) holds the current at 5A, until SOC corresponds to (controller setting of) Float Voltage (13.5V)? Question: does the controller actually stop charging at this point? ie: No 'trickle charge'?

Obviously, this last is one of my stumbling points. If Absorption Voltage is constant at 14.22V, then when the charger switches to Float mode, the battery voltage will read 14.22, won't it? In which case, 'Float' voltage will read high at this transition point? Or does the Absorption charging voltage drop as the SOC gets closer to Float?

So my confusion comes from Crown specs being unclear to me, and names of 'phases' and specifications not corresponding between VictronConnect, and Crown, and the Victron controller not having specified a 'constant current' for the Float mode

As I said, I'm new at this, and my Victron controller readings aren't following my understanding of the way it should work. For example, during the controller's Absorption mode (set at 14.22V in the app), the voltage will read 13.55V at 1.7A, which seems more like a Float to me. It's a cloudy day, but it seems it could be charging at 14.22 at 1.6A, per the Absorption app-setting. Or is this possibly the temperature compensation?

Ii appreciate any clarity anyone can give me on this!

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.

The Centaur charger, 12/40 has 3 outputs. If The engine battery, AGM, is connected to O/P 1 and the Lithium house batteries are connected to O/P 2 and 3 is this a safe option as both use the AGM setting of the Centaur for battery chemistry?

Do the three outputs work independently with respect to Bulk/Absorption/Float? Meaning if the engine battery is fully charged it goes to float and the outputs 2 and 3 remain at Bulk until the house have reached appropriate voltage to change to absorption/Float?

Is the another option to have 2 x Lithium and 1 x AGM safely being charged from the Centaur?

Many thanks

I'm looking at upgrading our boats electrical system to a LiFePO4-based system. As far as the components go, I'm pretty sure I have the configuration figured out. The only thing I cannot determine, is whether our current Victron Phoenix Combi 12/1600/75 Inverter/Charger is compatible with the VE.Bus BMS. The setup I am thinking about is very similar to the example given in the VE.Bus BMS manual, shown below. Can we use our Phoenix Combi in this setup?

Hello! Is it possible to use 100% Excess power when the battery is full? Or use 50%/50%, because i don't want to use the energy from the battery ( and shorten their lifespan )to the inverter on a sunny day.

I have Victron multiplus 48/3000/35-16 in my basked and i dare not to buy until my question is answered : )

best regards

I'm looking for a universal inverter/charger solution for my boat so that I can handle any shore power source I can run into around the world. It thus needs to accept 120V and 240V AC at 50Hz or 60Hz, and be able to convert it all to the boats 120V 60Hz AC.

I have not been able to find a single Victron product that would do that. Is there a combination that would?

Hello community.

as there is no help topic in the VE Configure 3 software about the "Charge efficiency" setting, I would like to ask what value I should enter for my system?

I have a Multiplus 24/3000, Venus GX, an AC coupled Fronius Galvo inverter and a MPPT 100/50 at the DC side. Both are charging an Exide Sonnenschein A602/750 battery bank with about 1400Ah.

Currently I entered 0.90 but I am curious, so what is the exact effect of this setting? Should I change it?

Thank you for your help.

Phoenix multiplus 12/2500/120 in my narrowboat. I've noticed during the night that every 29 seconds, the unit gives a brief (1 second) hum/buzz. After a while, the intervals are short to just a few seconds but quickly reverts to the approx 29 second intervals.

Have not noticed this on other inverters (Victron and MAstervolt).

Does this indicate something could be wrong? There are issues as the dip-switch settings are not saved, including a reset to default.

Thanks

The need...

On a boat we have a power snorkel (think diving using an air tube with an air pump floating overhead) and looking to change the AGM batteries over to a Lithium battery. However, naturally, it’s not that simple.

We have an Enerdrive LiFePo setup charges by a Phoenix when on shore power and a 100/30 mppt smartsolar plus alternators while at sea. Don’t want to include the 240v/Inverter in the charging setup as it chews power on standby and the batteries run down when the boat is not in use.

So the simple part of the requested recommendation is for a lithium friendly charger to run off the 12 DC circuit tocharge the new Lifepo4.

The second more complex issue is that because the power snorkel is not used that often the battery sits idle for weeks, months some times. I would like to store the battery at around 50% if charge and it would be brilliant if someone could recommend a way of charging to 50% !!! Weird huh!! But I think you know why!

Anyway, that’s the two part request.

Thanks in advance

New to solar and charging....I have 600W of solar panels on the roof of van. I have two 12V AGM batteries connected to the panels via MMPT charge controller 150/85.

The battery is for example at 95% charge. The charge controller is saying that it has 15 amps of current to send to the battery, but when I view my battery monitor, it is showing that only 8 amps of charge.

Is this due to the state of the solar controller? (its in the absorption state currently) I dont quite understand the various states as I have not looked up what they all mean. I assume becuase its almost full that it slows down the charge rate? What state is where it sends full charge controller current to the battery?
