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.

Needs:

  • 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!

Wiring 3 parallel batteries with IP22 w/3 outputs

Hi,

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.

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).

[image]

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.

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?

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.

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.

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

Hello

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.

Victron Blue Smart IP22 Charger 12V 30A Battery Connection Terminal Size

Hi

I am deciding to purchase

Victron Blue Smart IP22 SLA/LiFePO4 Charger 12V 30A

The battery connection terminal is listed a being for 16mm2 or AWG6 in the manual.

Could the manufacturer or someone that is capable of precise measurement please advise what is the actual size of this hole.

What is the precise size of the battery input terminal ?

Mathematically it has to be bigger than 4.52mm D

To accommodate 16mm it is probably at least 5.5mm D (cabac cable lugs have a 5.5mm hole to insert a 16mm cable for example)

https://www.cabac.com.au/amfile/file/download/file/114523/product/138718/


Can it fit a 6mm D copper stalk ?

https://www.cabac.com.au/p/electrical-power-connectivity/lugs-and-links/copper/cs25-6


Can it fit a 7.7mm D ferrule ?

https://mm.mmem.com.au/caablp2500


Yes I am trying to use 25mm cable for 'reasons' being that is the cable I have got already.

No I don't want a stud with a 25to16 tie tail.- Looks rough to me and I'm not keen on extra connections joints and hardware just because Victron didn't think to put a 6,8, or 10 mm terminal stud on this item.


Any help much obliged.

IP22 Charging 2 battery banks

Hello all. I just received my IP 22 30A/3 output charger. I intend to use it to charge a 12V starter battery and the house bank (2 12V batteries wired in parallel).

Is the IP22 smart enough to charge each bank correctly even if they are at different states of charge?

What is the recommended way to wire the charger to the house bank (2 12V batteries in parallel)? Should I run a wire, from the charger to each positive pole or is it ok to run a wire from the charger to one of the positive poles?

All batteries are flooded cell lead acid

Thanks in advance

IP22 charger absorption voltage way too high when joining a VE.smart network?

Hello all,


I have a IP22 to charge a bank of Battle Born Lithium batteries. On its own it works great. But when I join it an existing VE.smart network with a MPPT 100/30 and MPPT 100/50 solar charger, plus a BMV-712 battery monitor, it all goes wrong. As soon as I join the network the absorption voltage goes from 14.4V (which is correct) to 16.32V. Oops. That is not good. When I leave the network, all is well again. This test was done with the two MPPT chargers not doing anything (no sun on the solar panels). Anyone have any idea?

Thanks for all your insights!


Here's the weird Absorption voltage of 16.32V

IP22 rev2, MPPT, syncronized charging: how the storage phase is handled?

The second hardware revision of the IP22 is now supporting VE.Smart networking. It looks like Victron fixed the "too small microcontroller" issue in that revision. That is pretty cool!

https://www.victronenergy.com/live/victronconnect:beta

There is a guy here that reports it is working for him.

https://www.t6forum.com/threads/low-temperature-lithium-battery.24971/page-10

When I look at the release note, see "Blue Smart Charger" section of the v5.42 release, I have few questions about synchronized charging of an IP22 and a Smart Solar MPPT unit. It is said the IP22 will become the charge master in a VE.Smart network. That makes sense. However, even if the charging profiles are configured identically on both IP22 and MPPT, only IP22 supports a storage phase in its charging cycle.

So, what happens to the MPPT when the IP22 switches to storage phase of its charge cycle at the end of a long sunny day? Similar use case, what happens to the MPPT if the IP22 is already in storage phase when at the beginning of day? Does it mean it require the storage voltage of the IP22 must be set the the same value of float voltage? What happens if it is not the case (storage voltage lower than float voltage)? Is there any plan to add support to a storage phase in the charging profile of MPPT?

Regards,

-François
