Absolutely the best video I've seen while researching a solar setup. My setup im going for is ac coupled, but still loads of good info in there.

This was fantastic, very clean, and clear. Thanks
I love your presentation style.

This installation will provide for the spring, summer, autumn and winter with or without sunlight.

Another good found video for my war chest.

Slight mistake describing the SCC specs ( _Victron specify Nominal PV specs, not Maximum_ ) but otherwise a great video and a very impressive system.

I am in the design phase to transform a Sprinter 211 cdi, new (2021), L1H1, all a little tight !!!!, but perfect for use here in Europe and exploring small towns, easy to park ... etc
But now I got to the point of doing the electrical project, which I'm not used to doing, I'm a civil engineer, I understand 110 / 220v AC circuits.
I wish you could help me with that part.
I'm Brazilian, but I also live a lot here in Portugal, where I'm going to do the conversion.
Well, I started making a spreadsheet, with the equipment, the necessary power and time of daily use, I have no intention of filling the motorhome with things, not least because it is a Sprinter L1H1, and I would like to have a simple electrical installation, but I would not like have gas inside, so I would prefer a stove with only one induction zone.
To heat the water it would be a D6 truma, which is diesel.

But from the calculations I made and compared with others I saw on the net, it seems that it ends up consuming a lot of energy, making the electrical part more expensive.
I don't want to spend so much just because of induction.
I don't know what other electrical equipment I would still need for everything to work, still using the car's alternator and an external 220v point when stopped at a camping site.

In your opinion, which a good configuration sufficient to have a quick meal, with induction and stay out of the network for a day or two?

Well, the result of the spreadsheet was:
220V equipment
notebook - 65w - 1 hour of use - 5.4 Ah
induction cooker - 1800w - 0, 4 hour of use - 60 Ah

12V equipment
USB - 50w - 1 hour of use - 4.2 Ah
refrigerator - 45w - 8 hours of use - 30 Ah
lights - 15w - 3 hours of use - 1.3 Ah
water pump - 42 w - 0.5 hours of use - 1.8 Ah
exhaust fan wc - 40 w - 1 hour of use - 3.3 Ah
I will be very grateful if you can help me by presenting an wiring electrical diagram with the necessary equipment.
I appreciate if you answer.

Great video. Thanks for the detailed insight and diagrams

A battery shunt with a temperature sensor might help disconnect the battery on extreme battery situations.

There is, also, a voltage sensor that does the same if the voltage is out of range.

[niceguy]

Just an observation, not criticism: Other rack mounted LiFePo4 solar batteries are networked and provide state of charge to the rest of the system. So these PowerPlus Energy ECO don't seem to have that feature.

[rafaelsyc]

The explanation is great, thank you very much for it. Could you please tell me the characteristics of the different current protections (battery fuse dc isolator, mppt charge controllers, pv array dc isolator for mppt 1 and 2)?

[kobusfilmalter]

Could you please update us an this system now that is more than two years later? Changes, or added devices, ext...

[stevelamperta]

Instead of buying two charge controllers, wouldn't it make more sense to buy one big charge controller like the 250 / 100 ? it would be cheaper also ! can you comment please

[delodelo]

Great info thankyou 👍👍. Should do more

Hello, I have a quattro 8000VA inverter, I also have a 220 mains. I'm interested if you can set it when the 47v voltage reaches the 220 mains. Without charging from the mains. Thank you

[nathanmitchell]

Great setup well done. If i had a DC generator, how would this work with this system or would you need a different inverter?

[pavementslave]

Hi, there new to solar, I have a 10kw Victron quattro inverter, my house supply is 3phase 40A what will the supply size to the inverter be?

[BackyardAussie]

Great video.. are the batteries connected with the can port or does the BMV take care of the settings for charge and discharge??? I am looking to get the victron multiplus 2 to use with a 15kw lifepo4 battery pack which doesn’t have a can port so need to work out if the Multiplus 2 can set manual values for DOD charge etc???

[karlposa]

Good video but why did you choose not to earth or ground the MPPT???

[MrDenisJoshua]

I'm looking for inverters that can be connected at 100 of 400W solar panels and also charge a 48V battery bank (near 50 kW).
Can you give me an idea of what type of inverter (and how many) for this type of PV please ?
Thanks a lot for your video
