Ip 67 IP22 some of them have three outputs. What does that mean? Does that mean it has various amperage outputs? I sent an email to the company in Deutschland and they have no clue
What company did you email? Victron is based in the Netherlands, and they do not really have customer facing technical support. They sell through distributors (like us!), so wherever you purchase your products is the best place to ask the questions. This is why it is important to support independent sellers instead of amazon. The 3 outputs means it will charge 3 separate battery banks of the same chemistry. This is mainly useful on boats where they often have an engine starting battery, a house battery, and a thruster battery (all AGM, all same voltage). This would not work properly if the batteries needed different charge profiles (example, one lithium bank and one lead bank) because it charges all of them with the same settings. It does keep all 3 batteries separated though, so your house bank could not drain your starter bank, for example. They do not have varying amperage outputs. All 3 have 30A output available, but the total is also 30A, so this is divided between the banks based on whichever needs it the most. If you have further questions, please give us a call!
Sort of...with a 4 terminal unit(3 positives and 1 common negative) you can charge up to 3 battery's at the same time...if it's 30 amp unit you'll get 10 amps per terminal with 3 battery's on charge...if only using 2 outputs then 15 amps per output...hope that helps
Technically, yes, you should use a smart battery protect, and connect the allow to charge signal from the BMS to the H pin. In practice, if you have the Blue Smart Charger set to smart lithium mode, and you are confident the batteries will not be facing extreme temperatures, it is going to be fine to skip the BMS.
@@MobileSolarConsulting thanks for the fast reply! I’m putting together a parallel Victron battery bank, and the Victron lithiums are recommended to be initially charged before use in the manual, so my question is, if I’m wiring them in parallel do I still need to charge each battery before the install? Or can I hook the batteries up to the system right out of the box and just make sure to charge them before actually using the system? The manual is not clear if the batteries need to be installed at the same charge if in parallel. I hope this makes sense!
In Australia WE HAVE 35C AMBIENT and I have had two of the sealed IP65 die, they get so hot, they can't be touched and start to scream shriek loudly. I can't recommend them for charging a flat lithium battery of over 100Ah as they will overheat before it is charged. (I am Elec eng) The best charger for continuous is the centaur, however they are also 73% efficient. I ended up making my own charger with a 12v toroidal 50 amp transformer, an Ideal diode mosfet bridge and a 2500mfd capacitor. This charges at 50 amps with 95% efficiency. My little 1000 watt Yamaha generator idles while running the toroid charger but makes funny noises driving the Victron switch modes, which i believe may lead to the inverter in the generator failing.
Congratulations on your charger that you built - sounds very effective. In our area, it is very common to have 90F weather with high humidity and we use the IP65 chargers outside for 2-3 days straight without issue. They certainly get warm, but they don't break. We've had ours for over 5 years now.
I have all three of these. They are not very efficient, I measured watts in vs watts out, best I could get was 75% at rated output. Poor for me when running them off a small generator, to waste 25%!!
Specifications sheet, and our measurements, show 94-96% efficiency depending on the charger. Perhaps you are considering the full output of your generator? Your generator will throttle it's output when there is a lessened demand.
@@MobileSolarConsulting Well you are wrong. I use Fluke professional AC and DC wattmeters. At rated output, watts in at 230Vac and Watts out at 12v DC efficiency is 70% for all victron models, and the multiplus in charge mode too. Let them warm up for 10 minutes!
I have three of the Blue Smart IP67 24V 12A chargers. I just checked it carefully, warmed up, and got around 95% efficiency: 26.77V @ 12.3A = 329W on output 345W (497 VA, but 345 actual watts) on AC input (utility mains) 329W / 345W = 95.4% efficiency And that was measuring the voltage after not only the output cable that came with the charger, but about another 4 feet of 12 AWG cabling in addition to that. Power Factor isn't great, but in terms of real power the efficiency is quite good at its full output. So I think it comes down to how much power factor matters in the application. For shore power you generally don't get charged. -- Just for the heck of it, since I also have a 48V system with a Victron Phoenix 500VA inverter handy, I decided to also do an end-to-end test 48V system -> inverter -> charger -> 24V system to see what the combined efficiency is. The Phoenix is rated at 91% efficiency. So my expected combined efficiency is roughly (0.91 * 0.954) = 86.8%... but that's probably at a 1.0 power factor which we aren't at. 50.7V @ 8.86A = 449W @ DC input 342W (418VA) @ AC output (phoenix AC output), and the power factor is better too. 26.75V @ 12.3A = 329W @ DC output So here the combined Phoenix + Charger efficiency is 329W/449W = 73.3%, The Phoenix alone is 342 / 449 = 76.2%, and the charger is 329 / 342 = 96.2% (and 0.762 x 0.962 = 73.3%) So in this test, the Phoenix inverter didn't do so well, though it might not be a fair test given that it was pushing 418VA and it maxes out at 500VA. But the Charger did very well at 96.2%. -Matt
i got the first blue one ip 67 on my boat, but the fuse box always get to hot, and melted. without ruining the fuse....

Do I need to use my bms v2 to initially charge my VICTRON lithiums with one of these?
Technically, yes, you should use a smart battery protect, and connect the allow to charge signal from the BMS to the H pin.

@@Ajjakakkaka It is best to charge each battery separately before installation. For further technical support, please call or email.
super useful. thank you
Glad it was helpful!
Does Victron offer a 48v charger?
Not a handheld one, no
@@MobileSolarConsulting Use a 48V Multiplus inverter charger they work great, but only 75% efficient.
what wires to use for the IP22?
You have to make your own wires. 10awg 8awg or 6awg work depending on length and current.
Good info.
Glad it was helpful!

Great charger but no way to monitor remotely, BT range sox big time!
