I installed last night 3.68-beta and today v3.68 was on Victron connect, I bet its the same as the beta but official, I did installed it too.
It fixes the pulsing problem to a degree, in my case with IP22 HQ25 it was pulsing under 7A of load, not 5A as the update mentions.
The fluctuation now is 0.03v around the correct value, so 0.06v in total, but the most important thing is that the bursts of 12-30Amperes that hammered the battery every 5 seconds disappeared; now there is a steady indication of 1-3 Amperes, which is the normal load of the charger and the idle inverter.
So, it’s no dangerous anymore for the battery, but in my opinion, this small voltage instability is totally UNACCEPTABLE for a pro charger.
I m an electronic, but i don’t want to open it not to loose the warranty, but I may do it, this is my problem.
What is this famous additional hardware modification? A dried capacitor? something else? Why don’t you say?, you messed all up anyway, and Victron ruined its name and trust, because this issue will not stay only here in a small cycle; it will become viral. I promise you.
After installing firmware v3.68 on my IP22 charger (3 outputs), I have to report that current is still fluctuating between 0A and 15A on a fully charged lithium battery:
I also see incorrect voltage readings for the IP22 charger in Victron Connect. I have two Orion xs 1400 and a smart shunt connected to the same battery together with the IP22 12-30-3 charger. On the screenshot both Orions and the smart shunt correctly report about 13.9V but the IP22 charger says 13.47V:
Latest firmware v3.68.
The charging voltages are off the default settings, instead of 14.5V in Bulk, it goes all the way up to 14.6v, not a big deal someone could say, it is a big deal as I have to go to measure the real voltage, this charger cannot be trusted.
Also, the Float voltage is at 13.92 Volts. Why? Where is the default 13.8??? And it’s still stacked at Float for 12+ hours despite the discharge being only untill 12.5Volts in batteries. This charger cooks the batteries, its dangerous!!!
I’m a charger’s babysitter with a multimeter on hand!
Yes, I though so for a minute, but the point is that temps are warmer now than in winter, so it’s not a possibility. If it were colder, yes, it would be possible to push some more voltage, but it’s the opposite.
And, after all, I canceled the charging and started a new cycle, and everything went fine this time. This is an issue from the first day.
Anyway, speeking with the dealer, they don’t accept replace after 15 days, that’s rediculus, how someone can spot all the issues within 15 days?.
If they accept it, in my case, they accept only within the first 15 days. Good luck to anybody.
I turned mine into a power supply, with 2 settings, 13.2v and 14.5v. I always apply 13.2v, and after a discharge, apply 14.5v for as long as the current falls close to zero, replacing the broken logic with human interaction. No pulses, not spikes, not voltage instability.
The 5 year warranty is ultimately with Victron, so your supplier is obliged to honour that. Raise a support request in the normal way, and escalate to Victron if you do not get a satisfactory response.
Yes, it will take a little while, but Victron are 100% behind this.
I have an IP22 with this same issue, and have made comments in the discussion above. Kudos to them, following those comments, I received correspondence directly from Victron tech support by email picking up on my concerns and continuing dialogue with me.
The local (UK) supplier has also been supportive, although not initially aware of the depth of the problem, but since seeing this forum discussion, has accepted my RMA request and currently waiting for new stock in April to fulfil it.
Frustratingly slow, but that is the nature of electronic production lead times.
Sh1t happens, but my experience here is that manufacturer and supply chain have done their very best to initially try and fix the problem by firmware to understandably minimise their own costs, but then hold their hands up and do what they have to do.
Sure, I agree.
The problem is that new devices are not yet available. I will have to wait a month or so, then I’ll call the official supplier according to my serial number, and I hope they will accept a replacement.
Or better, i already filled the RMA request to my supplier.
Another issue, that is not mentioned here, after a medium discharge, it always enters Absorption .016Volts higher than selected, and after Absorption continues to Float with this same ofset, 0.16V more than what’s in the settings.
So, if I want to Bulk with 14.5v I must set 14.35V in settings, awrfull!!!
I have just removed the auto close timer on this topic, but it might pop up again if another answer is accepted.
I don’t intend to have this topic closed until new production IP22 chargers are in the channel and available for RMA replacement for those who aren’t solved by firmware.
Have a IP22 12|30|3 (all 3 banks connected) serial # HQ24 exhibiting similar pulsing behavior. Updated to firmware v3.68 and issue seemed to have get worse. Could this be related to the puilsing issue with serial HQ25 - any suggestions welcome
