what device or part do I need for this?

Hi all. I am wondering how people set up the preferences in the MPPT and BMV712 as far as Charged voltage Absorption voltage Float I have 2 Dakota 200Ah 12v Thx all!

No. Should there be?

Here's what I am buying for my boat: 1200 W (2x400w and 2x200) solar set up on my boat. 2x 400Ah Dakotam Lithium LifeSp04 Battery 12v 4x MPPT Victron 100/30 1x INVERTER / CHARGER Victron Multiplus C 12/2000/80-50 120V DC to AC inverter and charger. 1x Victron Energy Cerbo-S GX for System...

I actually did a summary of what I'll be needed

I have 2 Dakota Lithium Life04 batteries

So if I add Bluetooth device I do NOT need to connect SHunt to CErbo?

not sure if you were looking at the updated file I posted two replies up…. Replying to Maikail. If I understand correctly: . Removed Digitial Multi Control panel . Add BMS - where does it go? QUESTIONS: My batteries don’t have Bluetooth. What would you use? When I add Bluetooth, will I still...

Very great point. It is also easier harder to DIY repair where a victory system is all open and all parts accessible and visible

Thx!

Great points!!! You seem pretty knowledgeable. For a 400w panel what Victron MTTP do you recommend?

I bought the batteries, I am just putting the puzzle together to get the solar energy to the batteries.

what I meant by regular is connecting the solar panels to MPPTs, then Inverter/charger, BMS, B2B and lithium batteries. A lot of parts to buy and many opportunities to mess up. The EcoFlow seems a great option. I just wonder why nobody in the liveaboard world talks about it. Everybody is putting...

Sorry for the question to be so unclear. I have a sailboat and 1200w of solar panels. I will be living off grid in the bahamas I was going to go the solar-mppt-inverter/chareger-400Ah Lithium LifeSp04 12v Now I am thinking: what about those big power station that can use solar to charge like...

Amen!!! Thx

Thx so much!

oh man.... last shot and I'll leave you alone :-)

Awesome!! Thx

Closer?....

WOW!!!!! Thx so much.

sounds good. I don't mind a little extra $ when justified.

so what do you suggest? (and thx for the input)

wow.... thx... What do you think about not using any switch as the recommendation I received previously? Maybe I should have them closer to the batteries?

sorry, what do you mean exactly? the switch between panels and MPPT?

firs off thx! what do you mean by "same bus bar for batteries"? Isn't it what I have already?

12v. May I ask how you calculate?

Hi friends. Trying to pick the right MPPT(s) for my boat, leaving off the grid 2x 400W solar panels Voc 49.1V Isc 10,41 2x400Ah LifeP04 12v I’d like one MPPT per panel, for reduduncy Thx!!!

Some people say that if one MPPT goes down at least I am still able to create some energy… I’ll be on a boat, offshore. What do you think

Thanks so much for the feedback. I’ll fix as you mentioned

For my sailboat, 800 W (2x400w) I don't worry yet about the specs of each item. Thx friends!

thx I'll try to call tomorrow to see if they can advise me for marine / boat usage.

Hi all. We are moving on our boat in the bahamas and we will rely on solar energy only - planning on getting 800-1200 W. 2 rigid panels will go on an solar arch in the back of the boat and some flexible panels on the Bimini. To keep the thread organized and focused, I just need advice on BRANDS...
