Dual Battery system

So since about September i have been busy buying components for my dual battery system. I went the victron route simply because ctek nor wrnd was ticking all the right boxes i wanted something that could take charge both from the alt and solar at once and victron was the answer combined with Lifep04 battery’s that Tijmen suggested and i must say they are worth the money. Currently my battery box is wired and working pics to follow in here i have 4 3.2v 120a/h giving me a total of 13.2v in a package that weighs just over 14kg for the whole battery box and then going with that i went for a 12/24 220amp battery protect from victron and a bms from the place i bought the battery’s from. Then the second part of the build is the victron dc-to-dc charger with a 30amp charge rate and a victron mppt charger also with a 30amp charge rate. The bms allows me to charge 60amps wich means i can charge with both my dc-dc and Mppt a total of 60amps max. I opted out for 2x160 watt fixed solar panels that still needs to be installed on my rtt and on a later stage i will get a 100watt panel for a mobile option.

Weirdly enough I am busy with the same thing.
I quick question regarding the Victron. Does it have some sort of remote monitoring ability? As this would be a necessity for me.

Depending on what you buy the Bluetooth units have remote monitoring to any mobile device. All you do is download the victron app and you can monitor remotely the dc-dc doesn’t offer any helpful information really all that you see is the state of charge of the battery and the input and out put volts on the other hand the Mppt is like Wikipedia it shows you the wattage that is being harvested the amps that the panels give you it data logs each day’s usage the amount of wattage it harvested everything. The app is also your setup for settings so u will basically set your charge limits battery selection etc via the app and it will automatically save it in the controller i will take some screenshots of the app and post it. The first 2 photos is a Bmv if you want all your info regarding battery you can add that to your system but it is R3500 just to see what wattage your system uses and so on
