I have seen various tubes on this topic and I learned some more on readings etc. I am using my system stationary in a near off grid set up (best of both worlds I guess) and you showed information that was helpful and expanded my display readings etc. One thing I do and had a problem with is / are settings when the MP II updates. I was on 5.06, my AES stopped working. Then when I went up to 5.08 it automatically set the PP II to Storage. So finally got my windows and stuff and fixed most of it. What brought me here is looking for settings for the MP II and it may be a good topic if you haven't done it.. but ... the idea is I want to run on batteries down to 50 before the shore power recharges. When there is good sun I want to have it charge first and only and not use shore but when the time comes or needed 50% then the shore comes on. It seems the shore wants to take priority. I thought I figured it out but then 506 came in and I had other things to do... I am going to check some of your other videos. I have no tanks as per se but can find one to design to use etc. Keep up the good quality .. pat
It my rv stays plugged in for 3-4 months how can I easily keep the batteries charged at around 50%? do I have to use the dongle and bring my computer into he rv just to do this?
Hello Sir, I have the following questions regarding the charger I have installed which is Multiplus II GX, 48V, 5000VA connected with 4 batteries with 200Ah & 12V each 1. The charged voltage should remain as a single battery voltage? Just maybe 13.8V or should be multiplied by number of batteries that's 4? 2. Before configuration must the charger connected to the internet or I can configure on bluetooth connection? 3. I found only the charger in bluetooth list devices without seeing it's components like Batteries as I see on your videos, and then after clicking on the charger what I could see is it's details like change, edit and wifi enabled, what is the problem? Please help me as only configuration remains.
Assuming you have LiFePO4 batteries 3.5V/ cell is a fair compromise (with 3.6V charging goes little faster and you get little more energy inside, but with 3,5V / cell you still will charge relatively fast while improving live time of batteries ( which live longer ehen kept between 20% and 80% state of charge , so for a 48V system of 4x 12V batteries you "ll have 16 celstraf in series and charge voltage should be 16x3.5V or 4x14 = 56V.. (NB some integrated 48V batteries have only 15 cells iso 16 and then charge voltage should be 52.5V..Most important for system safety that BMSs constantly monitor voltages o ALL individual cells and that BMSs ensure charging or discharging is stopped immdediately when any of cell voltages goes outside safe range Max 3.65V en min 2.9V/ cell. Charge can be a MPPT ( (solar), DC-DC (car alternator), mains charger or portable generator charging, when configuring maken sure you don t charge below 5Celcius (frost) and not more than 0.25C (85% SOC in 3 hrs when started with 10% SoC..method of configuation of each individual charge depends on type/ leven is smartness of charger you use, what is crucial that battery BMS controle stopping of charging when limit voltages are reached. If overcharged LiFePO4 can be very dangerous while old fashioned PbSO4 batteries only boil away some elektrolyte, LPS can rally "kaboom"...
I got it from Buffalo Exchange in SF. Its Faherty brand. fahertybrand.com/collections/mens-new-arrivals?gclid=Cj0KCQiAm5ycBhCXARIsAPldzoXpH9epSeYWDzvjP3EsUZqOH_xcwTN_jr84ssk4aaWmqnbw6rHgkBgaAozEEALw_wcB
Mentioning how much AH your battery bank is, is not specifc: energy storage capacity you measure in Wh, assuming "default" battery banks are "12V" is OUTDATED. And installing systems with regular currents above 150A is NOT smart, it is inefficiënt and expensive! For instance 200Ah@ 24V is much beter thans 400Ah@ 12V you might consider 100Ah @ 48V (all with same amount/ cost of batteries)....
Fantastic walkthrough and very much appreciated.
Very welcome!

great teachings to the point
victron professional also has this
16.15 I'm new to my campervan. My question is do I keep the Inverter off when I'm parked up or just left on charge only. Thanks
Most people only turn on the inverter when they need AC power. Otherwise keep it off (or charge only) to conserve power.
@@VanLand Thank you, very good videos.
Very helpful video, thank you!

Drop ur float to 13.2v
thank you! would love a class, consult, more resources....
I was just told by Victron that upgrading the firmware on my Multiplus was not needed!
It's too bad that Wakespeed and REC-Active BMS doesn't have a nice video like this!
I don't see the link to the firmware.

Unfortunately, installing a 24 or 48 volt system in a small space introduces a lot of issues like product availability in higher voltages.
