Can ip22 output be connected to positive strip?

My ip22 is connected to a common negative strip and a common positive strip. The two 100Ah Renogy lithium smart batteries are connect in parallel, also to the two strips. Output from the ip22 is 14.2V but 0A.

IP22 / LifePo4 Compatibility question

I am using a IP22 Smart charger and so far, it does a great job of charging LifePO4 batteries after getting all the settings right. Here is what is happening when I don't want it to charge :

1>. Battery is stored @ 65% SOC , no charging during storage (RV storage facility)

2>. Nominal House Current is 1A, due to security cameras, BMS & LTE modem

3>. If I leave battery connected and charger not on the battery drains as expected

4>. If I leave the battery connected and charger on power supply mode, with voltage @ 12.8V, battery seems to be fighting the charger (i.e. battery BMS shows battery is absorbing current).

5>. If I disconnect the battery and leave power supply mode on , all is good but then prior to charging I have to manually switch the battery back in. This also throws off my PICO SOC.

6>. If I leave the battery in the circuit with the charger enabled the charger charges the battery to 100% and maintains it - DONT want that !

So the question is this - is there a way to leave the charger engaged WITHOUT the charger topping off the battery -OR- leaving the power supply mode on without the battery fighting it ? I want to leave the base van systems on AND the battery in the circuit WITHOUT damaging either the battery / BMS or the charger !

If I leave the battery in the circuit and the charger in power supply mode - will the battery voltage eventually equalize with the charger or will it just continue to fight with it ? If they equalize - should I set the output voltage of the IP22 to closer match the current state voltage of the LifePo4 ? (i.e. 13.2 instead of 12.8) ? I believe what is happening is the higher voltage (battery) is trying to "charge" the lower voltage (power supply). I did play with the outputs - when I bumped the voltage up it started charging the battery by a couple of Amps.

Bottom line - I want to be able to fully remote manage these setups - as of now I have to be present to manually flip the battery switch and change from power supply more to charger mode to charge before trips - its a waste of time - I would rather just go into the victron settings and turn the charger on remotely via my phone app and a remote control app.

Ideas ?

IP22 charger going straight to Absorption

I have a Victron BSC IP22 12/30 charger and a 120AH Lithium battery When I connect to 240v power, the charger immediately shows a voltage of 14.2v goes straight to Absorption, irrespective of the actual voltage. The charger is set to the Li-ion profile. Below are screenshots from both the IP22 and Smartshunt.

Can anybody suggest how I can get it to Bulk charge before going to Absorption?

Battery charged from multiple sources

Hi I have MPPT charger 150/35 which is Ve.Msart network with Victron battery sense and that was charing until recently one AGV battery 200Ah . Recently I decided to change to LiFePo4 on my boat and after investigation I decided to to order Victron Energy Orion-Tr Smart 12/12-30A (360W) Isolated DC-DC charger the idea behind it is to protect y not so smart engine alternator. So as far as I can see this is not posible to connect the VE.Smart network so it won't be aware of the there charges on the battery . And then I also want to order the Victron Blue Smart IP22 charger will will allow me to charge the same battery usage shore power . That device is also not Ve.Smart network compatible to it won't be aware of the other two chargers that will charge the same battery. The new battery is 180Ah . So my question is can I connect them all to the same battery . Will they be able to charge simultaneously the same battery do I need some smart device between the chargers and the battery to control the power and the cycles . I can't find that information anywhere on the site . I guess the idea of having the VE.Smart network would of solve this issue as they will start talking to each other but at the moment two of those devices are ot sporting it . .

Requirements for outside cabinet for Multiplus II and SmartSolar

Hi all,

The Multiplus II and other Victron products are IP22, but I would like to place them outside.

I cannot find much examples of people doing that, only some pictures.

My plan now is to find some cabinet/box with waterproof door, and make 2 holes in it for fans to blow in and suck out air. These fans should be temperature controlled (and not running when cold).

I guess the next big topic is condensation. This shouldn't happen when the fans shut off when the cabinet gets below 20 degrees Celcius. And the Mutliplus will almost always be running so there is probably always enough heat to prevent massive condensation.

Anything else that I should think off?

Thank you in advance.

IP22 12/30 compatibility with 100/20 controller?

My IP 22 12/30 has been the only power source charging my 12v Battleborn house battery. It is powered from an inverter connected to start batteries/alternator -works great never any problems, Recently I added 2x 100 watt solar panels in series and wired a 100/20 controller into the Battleborn house battery and if I run solar controller and IP22 at the same time the IP 22 is over heating, it also made a clicking noise. The solar works fine no issues.

Wiring 3 parallel batteries with IP22 w/3 outputs


I have a smaller motorboat with 3 parallel batteries. 1 starter and 2 consumer batteries.
I have bought an IP22 Blue Smart with 3 outputs, and I wonder how to connect them to the charger correctly.

I have made an figure of how I suppose is the correct way, but I am unsure if it really is that simple?
Should I add fuses on any of the wires?

Thanks a lot in advance for your support.

Upgrading my power management system to Victron and have questions

Hi All,

I have been running a 125 aH AGM in my camping rig (for coach battery) for five years and it finally gave up the ghost. This setup was only good for about 36 hours…so I ordered a matching pair of the same battery for a total of 250 aH.

Since I need to build storage for the additional battery, it’s time to upgrade my charging system. I’ve been doing a ton of research on Victron products and think I’m getting close.


  • Two VMAX SLR125 125 aH AGM batteries in parallel for a 12v system (both new)
  • Usually use less then 4 amps when boondocking (for a bedroom fan at night and fridge at all times)
  • Will be adding some LED lights for night use
  • Jeep has 160 amp alternator
  • Previously used a National Luna battery box and NOCO Gen2 (10 amp per bank) for shore power and charged straight off the alternator

Battery Specs:

  • Specifications:

    Nominal Voltage 12V

    20Hr Capacity 125Ah

    RC (min) 260

    Energy (kWH) 1.7

    Terminal Posts 8mm

    Dimensions 12.9"w x 6.8"d x 8.5"h/8.7th**

    Weight 75lb

    Charging Current* 8A-35A

    Charging Voltage 14.4V-14.9V

    Float Voltage 13.5V-13.8V

Plan to order:

  • Victron Blue Smart IP22 12/30 for shore power
  • Orion Tr Smart DC-DC 12/12-30 for charging on alternator
  • Victron shunt (TBD)
  • BMV-712 monitor (TBD)
  • Probably a Victron near-battery temp & voltage sensor (temp drops below freezing here in winter)

As you can see, this is a simple system and I’m only trying to add power for additional camp days. Solar charing is off the menu until I purchase a new roof top tent that will accommodate solar panels. For now, alternator and shore power will be the only charging methods.

I’m hoping that knowledgable people here can check my work and suggest any changes if I’m on the wrong track. There are no Victron dealers or installers in my area, and I worked in the car stereo field when young. I can handle the wiring, but it’s bee a while since I’ve tackled something so intricate.

Also, I’d like to make sure that all Victron components will handle a 200 aH LifePo4 bank in the future when these AGMs die again.

Am I correct in choosing a 30a charger for home and a 30a DC-DC for alternator charging?

Many thanks for any help!

Fischer Panda burn 2x IP22 chargers

I need the support of the cummunity to solve a problem whichs shows to be a conflict between a Victron Charger model IP22 12/30 (3) and a brand new Fischer Panda 1000i: Victron and Fischer Panda official support was unable, over 1 month, to propose a solution.

The story: a Victron partner technical team made an integration with Victron lithium batteries on an exsisting system made by GEL batteries, two inverter charger QUATTRO, battery monitor, and a charger IP22 12/30 (3) for the starter batteries. Present was also an old generator, replaced with a Panda 1000i.

When everything was in place an configured we tested the system. QUATTRO's and the new equipments inslalled for lithium worked fine in any condition, including when powered by the new generator. However when we switched on the IP 22 12/30 (3) to charge the starter batteries, it took non more that a minute to start smoking.

We stopped immediately the unit and then we did several tests to try to understand the possible problem.

First of all, we connected the IP 22 12/30 (3) charger to the quay net: the charger worked with no problem for more of half an hour.

Second test was to install it again in the original position, and try, first, to charge with the quay net connected to the boat. In this conditions everything was working ok.

Third test was to have again the generator as AC source. In a short time the charger started to smoke again.

Fourth test was to use one output only (the charger is a 3 output model): we connected each single output to one battery but the result was the same: smoke in a short time.

Next step was to replace the exsisting charger IP22 12/30 (3), 8 years old, with a new one. The result was the same: if powered by AC from the Panda 1000ì, smoke within less than a minute. If powered with AC from the quary net, no problem in charging, for several hours.

It's clear that there is a conflict between the IP 22 12/30 (3) charger, this specific model, and the Panda 1000ì.

Attached you have the pictures of the IP22 12/30 (3) opened after the smoke event. We circled in red the part we believe is the smoke source (L3).


I talked to Victron about the problem and they told me that they have never experienced any problem with Panda generators so it's a problem on Panda side.

I talked to Fischer Panda about the problem and they told me that they have never experienced any problem with Victron charger so it's a problem on Victron side.

On both sides no one try to discuss with the other side...

In short, we have a new Panda 1000ì which works ok with all equipment installed, but has a clear conflict with Victron charger model IP22 12/3(3).

It cannot be that we have been unlucky with two defective chargers. Must be a different reason. Which we don't know and we, as the situation is now, we don't know how to solve.

Please let me have your comments and, more important, let me know how to work on the problem and solve it.

Blue Smart IP22 Charger and Victron-Connect App

I recently installed a Blue Smart IP22 Charger (30A, 3 bank) in my boat. This is connected to my house battery (AGM) and my running battery (lead/acid/flooded). I don't see anywhere in the Victron-Connect app to monitor individual batteries. Is there a way? In the app it seems like the same charge profile is applied constantly to all banks (which wouldn't be very "Smart". Am I missing something here? Is there a way to visualize what is going on in each bank/channel? Is each cannel handled independently and the app just doesn't portray this? Is that is the case, which bank is being displayed? For the most part I will be wanting to charge the depleted house battery and simply maintain/float the running battery. I'm assuming that this is an extremely common situation.

Victron Energy Blue Smart IP22 12-Volt 30 amp 120V, 3 Output Battery Charger

I just got this charger and is pretty awesome that I can use the Victron app for the MPPT and this charger. I have a question, the app shows the 3 batteries (chins) 100ah each, at 13.3 volts each, the app shows they are in bulk mode. When I check their amperage with a clamp meter it reads each battery is getting .057 amps, is this right? Seems like they are in absorption mode, I'm confused.

Victron Blue Smart IP22 Charger

I have two 6v AGM batteries in my camper van that I want to swap to one SOK Battery LiFePO4 12V 206Ah. I also have a Progressive Dynamics PD-9245C Convertor/Charger that I need to upgrade to get a proper lithium charging profile. Would the Victron Blue Smart IP22 Charger be a good alternative? I like the bluetooth connection as well.

That's a mains powered charger. I also check this one: https://www.reddit.com/r/SolarDIY/materialssupply

Victron SmartSolar MPPT is the solar version. Also Bluetooth. but i think i can't satisfied, Is it good for buying this?

Low Temperature Cutoff not working


I have a Smart Shunt with latest firmware with a ve.smart networking setup to 2 MPPT 100/50 and 4 Ip22 12/30 chargers.

Everything is using the Lifepo4 profile with a low temp cutoff of 5 degrees C

It simply doesnt work with the charging continuing at 4 degrees C

Everythings firmware is up to date and the synchronised charging works perfectly but alas not so the low temperature cut off

Any ideas as to why?

Blue smart charger Functionality Device/App

A few questions about the Blue Smart Charger IP22 Rev2:

-How does the triple output work, eg have a trailer with main battery bank and then have a secondary battery used with a trolling motor. So the trolling motor needs to be charged independently from the trailer batteries. All batteries are LiFePo4. Will each charge at its own rate and once one gets to the charged parameters stop on its own?

-Are there multiple profiles in the app for each of the 3 lines one the triple output charger?

-Can you enable/disable charging from the app? Can this be done for each of the triple output independently?

Blue Smart Charger - Supply mode using Smartshunt or bmv-712 capacity values

I am wondering if the Blue smart charger can use the reading from the smartshunt or bmv-712 and at a certain battery percentage cut off charging and go into supply mode?

Use case is in a trailer with lithium batteries and the desire is to not maintain the batteries at 100% but instead 90%, while still being able to leave the charge plugged in which could run an electric fridge or other low draw items.

Ideally I'd want to be able to have the Blue smart start charging again under a specific condition, say voltage level or charge level but that is not totally necessary.
