Inside the Victron MultiPlus & a Detailed Explanation of How It Works

Johannes takes a MultiPlus apart and explains how the inverter charger works. He also discusses some power saving tips.

🎯 Key Takeaways for quick navigation:

00:30 🔌 Victron Energy uses a specific typology to convert DC power to AC voltage in their MultiPlus inverters and charger inverters, maintaining consistency across their product range.
01:20 🔄 FET power bridges in Victron inverters control the output voltage by changing the switching length of FETs, achieving accurate and stable sine wave output at 20 kHz.
03:08 ⚡ Transformers boost the low AC voltage (8-10V) generated by the inverter to standard household voltages like 230V or 120V, depending on the application.
06:42 ↔️ Victron inverters can synchronize with the grid power supply, allowing seamless transfer of power sources and grid assistance. A relay controls the connection.
09:56 🔄 Victron inverters can also act as battery chargers by regulating their voltage to facilitate battery charging. The charge current is controlled by adjusting the inverter voltage.

Wow what a brilliant video! I've often opened these devices and peered inside with very little idea what going on in there. I'm not an electronics technician but this was just at the right level for me to understand it. You are a very good teacher. I guess you know that all us cruising sailors love Victron. We need reliable equipment at the end of the earth.

this is the most detailed easy to understand explanation i have ever heard, thank you

[benveenema]

So awesome that Victron took the time to do this video! Love it!

Gidday Johannes

Excellent explanation video. Thank you.

I've been reccomending, installing and selling VE equipment for around 20 years and found the support excellent.

Thank you for quality products.

A+ Must watch for system builders. Especially explaining sizing the inverters for most efficient use. With a walk through efficiency of the FET's that make the sine wave for the inverter at 11:40

I want to live in that factory - and always walk around and see that nice things....great units Victron!

[rafam]

This is a professional and Simple esplanation. Excellent

[HarukiYamamoto]

Thank you so much for this.

Which size inverter can I use for a 136A surge current produced by a 3kW, single phase, 230V induction motor?

[Laurel-Crowned]

Can't believe I'm bearly seeing this video!

[tombouie]

Apparently, it comes from God, then to Johannes, & finally to everyone else.
Yous-bes The-Man Johannes ;)

[nielsdaemen]

Awesome! You make the best inverters/chargers on the market!

[tomtinkertv]

Very cool to go so deep!
Praise this competent presentation.

A wish: Could you do a tech explain vidwo about the various relays in CerboGX and the 250 mppt charge controllers, please?

[dogdooish]

great video, I use Victron for my whole house! :) :) I will be asking support some questions soon!

[abisaiamatalo]

Amazing videos. Your products look superb.

[gabrielbianco]

Que hermosa explicacion!! Muchas gracias!

My favorite product so far!! Thanks!! How does the AC sync handle an 'eco throttle' generator like a Honda 3K inverter series? When load is added, the engine RPM increases. Will this cause the AC syncs to slip? I'm in the US and use 120VAC @ 60Hz with 12V batteries.

[jimthvac]

which Victron inverters are Low frequency?

[alfrednudze]

Pls I have the victron and is 5000watts inverter but I want victron control charger. Pls how it cost?

[jmpattillo]

Does the relay close when the inverter is turned off, so that AC power passes from the input to the output?
