Hello, i have a Ford Tansit van converted into a camper and i would like to charge my leisure battery from the alternator. I was thinking of using the Orion-Tr dc to dc charger. Would this be enough, or is this even a good ideea? Or is there another way of doing it.
Thanks alot :)
I am commissioning a new boat which will have 3 x 160Ah AGM batteries for the 12V house bank. I have a 310W solar panel and propose using a SmartSolar MPPT 100/30 for this. I also have a "spare" 1200Wh 48V lithium battery and I'm wondering if I could use this as an alternative source for topping up the 12V system through the same solar regulator (having a switch to ensure only one source at a time). I would only plan to use this when sailing at night when my solar contributes nothing and I'm using a fair bit of power with fridge, instruments, lights and autopilot.
For the sake of this scenario I am not worried about getting the 48V battery recharged - that is another issue.
Any drawbacks in this arrangement?
I know that was already asked several times, but the solution is still missing.
The "Limit Charge Power" is missing from ESS menu, and if I got it right, this was the only solution to avoid charging batteries from grid, or, to set a certain limit. I know that there is an option in DVCC to limit the charge current, but this affects overall the charging, including the current drawn from a PV-tied grid inverter. In previous questions, disabling the DVCC was making the option to appear in ESS. Still in my case, using Pylontech batteries, I need DVCC on.
So, what is the solution to have the Limit Charge Power back on, regardless if DVCC is on or off?
I have a Quattro 10 000 connected to a Cerbo GX. My quattro is in manual mode, so i can decide if it is charging or discharging my battery. When i ask to charge 1000W, the input AC power follows the request but my DC power don't really follow it...
I don't understand why my DC power si so different from my AC power... Is it the result of the instability of the grid ? Because i'm conneced on a singlephase '' micro-grid '' which is generated by another inverter...
I don't understand victronenergy's adaptive algorithm well. Victronenergy says that the absorption time should be longer with a very discharged battery and shorter with a slightly discharged battery. But why? whatever the previous discharge, when the battery reaches the absorption voltage, eg 14.4v, it means that it is at 80% charged. Case 1: 100 Ah 0% battery, charged with 10 A charger. After 8 hours of bulk, it will be around 80%. And the absorption begins. Case 2: 100 Ah 60% battery, charged with 10 A charger. After 2 hours of bulk it will be about 80%, so as in case 1. And absorption begins. Why, according to the victronenergy algorithm, must the absorption of case 1 last 8 hours, while the absorption of case 2 must last 2 hours? Why,if both batteries are about 80% charged when absorption starts? According to electrical physics, providing a constant current of 10 amperes, any battery, at any level of discharge, will have the same level of charge when the absorption voltage is reached. That is about 80%.
I have 3 x 12V 95Ah AGM's in parallel and plan is to charge the bank with Dolphin charger when connected to shore power.
Which of below modes you'd choose for setup? If I got it right, "Calcium lead" mode would have the right voltages? I'm planning to use one of the posts of charger to connect the starter battery which is a traditional 12v battery so it would need the "Wet & flooded" option but which one you see would be a best option for this combo with 3 AGM and one wet battery?
Phoenix Cruiser B+ are designed to provide a charge to the house batteries via chassis battery/alternator when the motor is running. There is also the functionality, using a toggle switch, to charge the chassis batteries from the house batteries if the chassis battery goes dead. Is there any problem installing the Victron dc to dc Orion charger and keeping the present wiring to the solenoid?
I have a SmartSolar MPPT 150/85 VE.Can connected to 6 320W Renogy solar panels wired in 2 parallel series of 3 panels on an RV. I have 15A fuses on each string and a 25A circuit breaker in between the fuses and the MPPT charger. The new system has worked fine for weeks, until one morning after a day of the charger being in float mode for most of the day, both 15A fuses were blown, but the 25A breaker was not tripped. I also noticed that the charger said that the PV Array voltage was within a volt of the battery bank when the array was actually at 0V and/or completely disconnected.
After replacing the fuses, the charger seemed to work for the rest of the day. By the next day, one of the 15A fuses was blown. Part way through the following day, the charger stopped charging altogether even though no fuses were blown or circuit breakers tripped.
[image]Now, when the charger is in bulk mode during the day, it reports the battery voltage and PV array voltage but no (<5W) of actual charging, At night, it still reports a PV array voltage of approximately the battery bank voltage.
A bit of background to understand some of our choices.
We have a ship of 24 meters with is used for scouts and their camps.
The ship will lay in remote locations for a longer period of time, this means no shore connection.
Also it wont sail every day most of the time only to the camp location, so charging with alternator doesn’t happen verry often.
We have a generator on board but the less the better of course (cost perspective).
In normal use the ship wont use allot of power only a couple of lights in the evening and phone chargers and the refrigerators.
The ship has a Quattro 24|3000|70 and fits the job for us.
So a big battery pack is just fine for us.
The current batteries are at the end of life that they aren’t useable at all anymore.
We have found an traction battery pack for a fair price consisting of 12x 6Pzs 480 battery’s
With a Volt/capacity of 24 Volts and 533Ah/10h.
We are volunteers organization so funding’s are always an issue, that is why this pack is so interesting for us, It’s fairly good price for allot op capacity.
The big question is how to charge this pack. It consist of 12x 2 Volt batteries, do we need one battery balancer?
Do we need an extra protection/check for uneven 2v battery charging?
Is a standard BMV 702 capable of checking the charging state of this pack?
What are the configurations on the quattro for charging, can these be standard lead acid?
Anny tips for the charging this pack are useful.
Update: I've now tested charger in Power Supply mode set to 12.8A, with battery disconnected from system. The charger isn't capable of delivering 30A before output voltage drops unacceptably low. For 23A load charger voltage is 11.41V.
I'm sure now the charger is faulty, however I'm unsure if it's safe to use on my battery.
I have recently purchased a range of new Victron equipment and reputable 100Ah lithium battery for a campervan 12V system upgrade. After testing I suspect the new IP22 30A charger may be faulty.
Attached are smart shunt trends showing Li-Ion profile Bulk charge from 20% SOC starts at 30A as expected, and then unexpectedly reduces to a~20A after ~10 minutes.
Once steady at 20A I introduced load to the system to test if charger output increased up to it's 30A rating, but it did not. The trend shows introduction of ~20A load followed by a ~5A load.
If I stop the charge briefly it re-commences at 30A for a short time then reduces again to ~20A
To eliminate external causes I have tested the charger connected directly to the battery and witness similar behavior
If I set charge rate to 15A max I see similar behavior, with charge starting at 15A then reducing to ~10A.
I have charged battery fully, discharged to 20% and repeated test charge with same results.
Does the behavior indicated and tests conducted confirm a fault with the charger?
Could the abnormal charging damage my battery, or other components in the sytem (500VA pheonix inverter, 500A smart shunt, 75|15 smartsolar ).
My Multiplus, when charging batteries, is charging them at a higher V than in the settings.
For example - if I set the Multiplus to charge in Absorptions 14.6v and float at 13.8v - the BMV712 is showing charging about 0.2v higher - always. When in absorption it is charging at 14.8v and in float it is charging at 14.0v.
Any thoughts on why this is happening ?
Hello, I have a 100/15 MPPT connected to a small vehicle solar array. It currently shows a state of Bulk Charging, but it shows 0 amps under current PV and Batt.
I've checked all fuses and made sure it's set properly for my AMG battery. When I initially hooked up the MPPT it showed Amps for the current, but after about 1hour it went to 0 Amps and has never changed from there (multiple days).
Firmware has also been updated.
I have lithium batteries in my boat and do not want to charge them to more than 85% SOC normally except when I plan longer trips and want to top them off to 100%. Is it someway I can change that through either VRM or via Cerbo and Touch 50 without using VE Config? Would be a nice feature to have for managing lithium banks. Custom SOC and then shut off the charger when SOC is reached. Second feature would be to have the auxiliary charger on for maintaining current to the AGM starter battery bank.
I have a 100ah LiFePo4 battery and am considering the purchase of a Jackery 300 as a companion device. I can easily charge the Jackery from my big battery via the DC cigarette lighter chord that comes with the Jackery, but is there any possible configuration where I could do the inverse and charge the big battery from the Jackery?
Is there a smart LiFePo4 smart DC-DC charger on the market that would stay under the 12v 10a dc output of a Jackery? If not, would any of the AC chargers not surge over the max wattage limits of the 300w inverter? (And suffer the conversion losses?)
I realize of course it would be painfully slow, but if the little Jackery can pull 87w input from it's 100w solar panel, is there any way to pass that through on to my big battery without a separate solar charge controller?
Any Plans to make the Phoenix IP43 charger in 110v AC for North America. I see its only available in 230V.
I got a blue smart IP65 for my lithium batteries. Now, because of lockdown, my motorhome has been stood idle for many weeks and I want to put a trickle charger on the lead-acid starter battery during the coming weeks until the lockdown is over: is the IP65 suitable to use as a long-term trickle charger?
I am researching the IP65 12/15 charger. I see a nominal charge current of 15A and a low current mode of 4A. If I manually trigger the low current mode and then unplug it completely from both supply and load, will it "remember" it is in low current mode next time it is used?
If not, I assume I can plug it in and then set it to low current prior to hooking up the battery and before drawing power? Once it is manually put in low current mode, will it remain in that mode until manually set to normal current?
I ask incase I find myself with limited available current and want to ensure I remain fully in the low current mode.
Thanks in advance!
Any update on VE.Smart networking for the Orion Smart Tr DC to DC chargers? I'll have an MPPT and two 30A DC to DC chargers and it would be excellent if they all knew each other on the same battery bank.

Earlier today, right before noon, my main solar panel array on SmartSolar 150/100 stopped producing power. My smaller one (100/30) is still working. It was decently windy today, but my panels have survived much worse. I walked the cable and everything appears fine. Open circuit at the panels is 114v, right before the MPPT is 74v after a 150foot aluminum cable run. When I connect it to the MPPT, the panel voltage drops to that of the battery voltage and there is zero amperage. I tried resetting it, disconnecting and reconnecting it, etc. Does anyone know what the problem could be? This has bee working great producing 3k+ watts for the past few months. Here's a screenshot of when the failure occurred - is this a hardware issue?
I have a Mppt 100/50 and my charging amps have dropped down to a maximum of 7 or 8 amps when it used to get between 25-30 amps for 600watts of solar. I still get high voltage. My BMV is showing a current draw on the battery while the battery is being charged of up to 27 amps. No load is attached to the battery. This just started happening...before I was getting close to 30amps an hour charge from my panels.
My battery still charges to 100% but slower than before. After it is charged the current output on the battery slowly falls back to 0amps with no load connected.
Is there a way to configure the ESS with an MultiPlus-II GX such that the battery is charged mainly during peak PV power? In Germany there are funding programs where the grid delivery power is limited to 50% of the PV peak power and bound to a system charging the batteries during the midday - even if the battery could be already full during the morning.
This seems not only relevant for the funding but also helps to reduce the grid load, so it would be great to have it in the Victron ESS.
At the moment I am designing my (Victron) electrical system for our 4x4 campervan. Everything ok, but concerning the Victron charger, I am a little bit lost.
Here are the specs I am looking for:
To match this profile, I only found the chargers Phoenix, Centaur, and Skylla with an input of 110V AND 230V. And only the Skylla has also a profile for Lithium and is 'smart'.
So, at first I choose the Skylla IP65 12/70 (1+1). But looking at the specs, this charger is recommended for battery-banks with a minimum of 350Ah.
So my question is: Although it will probably be overkill, can I connect the Skylla to my batterie-bank of 200Ah without harming or damaging my batteries?
Or does anyone have another solution? Am I overlooking something?
Thanks in advance!
Dear Victron community,
I currently charge 1 SiO2 battery (max charge current 25A) with a Victron Orion-Tr Smart DC-DC charger 12/12-18.
Can I double the charge current if 2 of the same batteries are wired parallel?
The idea is to use 2 SiO2 batteries in parallel with the Victron Orion-Tr Smart DC-DC charger 12/12-30.
Victron Lifepo4 200Ah is currently at 3.13V per cell. Expected behaviour of the charger after switching it on: It should bulk charge the battery (LiIon-Mode enabled) with up to 30A and switch to absorption charge after the battery ist almost charged completely.
What the blue smart device does instead: It bulk charges for ~2s (yes, seconds...) and switches immediately to absorption charge for the next 2 hours with ~6A (decreasing over time). So the battery is never charged to its full capacity...
All parameters in victron connect app seem to be correct. 'Charged voltage' in BMS ist set to 14.0V, blue smart charges with 14.2V. Did I get something wrong? Any suggestion are welcome.
Buon giorno a tutti voi,
considerata la dimestichezza che avete con gli impianti fotovoltaici, sono a chiedere un vostro consiglio in merito per l’acquisto di uno o due regolatori di carica marca Victron. Perché i Victron? Perché la tensione – voltaggio di ricarica può essere regolato seguendo le indicazioni del costruttore delle batterie.
Fino ad oggi sto utilizzando un Western wrm 30 + che mi ha creato parecchi problemi, la ricarica oltrepassa molto spesso i 30 volt arrivando al punto di dover aggiungere mensilmente parecchia h2o distillata.
Purtroppo il banco batterie (6 da 12 volt -240 Ah) 2*3 in serie 24 volt – 720 Ah sono da buttare!
Al momento posseggo un banco batterie OPZS 12 pezzi da 2 volt – 730 Ah
equivalenti ad una tensione totale di 24 volt – 730Ah.
Come inverter utilizzo uno Studer XPC 2400-24.
La ricarica viene effettuata per il tramite di due pannelli Panasonic da 330W in parallelo, 58 volt (69.7 V), 11.4 Ah (12.14 Ah) e ulteriori due sempre Panasonic da 335W in parallelo 59.7 volt (71V),
11.3 Ah (12.16 Ah). Sono in chiaro che mi servirebbe una maggiore potenza per la ricarica ma le severe norme edilizie me lo impediscono. La casa si trova in montagna in una zona protetta e priva di rete elettrica.
Un vostro consiglio, quale(i) tipo(i) di regolatore di carica Victron dovrei acquistare? Con quali accessori per avere un controllo via telefono? Se ne utilizzo due, uno per stringa come vengono collegati tra loro (valori uguali di ricarica, equalizzazione, ecc.)?
Ringrazio di cuore per l’aiuto che mi vorrete dare e mi scuso per eventuali errori riferiti alle terminologie tecniche.
I have a Fronius Symo 8.2-3-M as well as a MPPT 250/100 in use. DVCC is activated and the charging power is limited to 20A. Nevertheless, the batteries are charged with more than 20A from the MPPT. The DC charging power is therefore not limited! Is this a bug or a feature?
My MultiPlus 24/1200 only charge the batterys to about 95%, this is only happening the last couple of months. When I switch the inverter of and then on again it charges the battery to 100%.
Is it possible to run a forecast based battery management? Considering Geo data, weather, ... The goal is loading the battery not in the morning - but e.g. at noon ..
In Deutschland , genauer gesagt in Berlin, gibt es Fördergeld wenn man einen Prognose basiert es Lademanagement umsetzt, die Idee ist den Akku nicht schon morgens direkt aufzuladen bei den ersten Sonnenstrahlen, sondern erst am Mittag , wenn Höchstleistung (PV) anliegt .. Auf diese Weise kann man eine gleichmäßige Einspeisung erreichen. Prognose basiert, heißt auch nach dass man Geokoordinaten mitgibt und eventuelle Wetterdaten berücksichtigt .. Es gibt ja die Möglichkeit über external Control eigene Steuerungen zu implementierenmentieren, hat das mal jemand versucht?
