Power Independent House using Energy Storage System & Solar

[@adamkuklych6672]

What a home. Now self sufficient. Wish I could afford all of that kit!!

[@afos3462]

You are living the dream of most of us would like for a later life. Enjoy yourself and I hope you both have a happy and fully technologically driven life.

[@VictronEnergyBV]

If Bert is anything to go by, it will certainly be fully technologically driven. :-)

[@Burwains_Energy]

Great video, what a beautiful house, lots of tech to play with!Also a great example of how Victron systems integrate with home automation easily.

[@godwillelectricals9431]

My kind of home. This is an inspiration.

[@scottwillow332]

8 years ago i purhased a Victron multiplus 24v\5000kw\120Amp unit with a pair of 150\100 Victron MPPT charge controllers. I had started off with an 20 year old 1000 Ah lead acid battery bank in rough condition. The system still runs without any issues 8 years later. The quality overall is nothing short of perfect with easy to follow programming ability and excellent efficientcy is unreal. I thought i had a bad battery so i reprogrammed both inverter and charge controller within 15 minutes.

[@VictronEnergyBV]

Thats great to hear!

[@bramcoteelectrical1088]

We use lead and runs 👍 great see our u tube using victron and built a very large off grid system

[@greglipschitz]

This is great to see. I love our Victron Multiplus II. We have it fully integrated with Home Assistant for automations and have 20kWh of LiFePo4 batteries and 5kW of Solar AC Coupled with a Fronius Inverter. It works amazingly well.

[@VictronEnergyBV]

Thanks for sharing!

[@matthewhigbee9744]

Looking forward to doing something similar in the California Desert. Very Inspiring.

[@shuhel02]

I am lost for words, the house is simply stunning. Victron and Pylontech seem go hand in hand and are appearing in all your videos, was hoping more information about the solar panels themselves would be presented. Home Automation is the way forward. Here's hoping Victron start working on an Amazon Alexa Skill, Apple HomeKit, Google Home, Home Assistant integration with their Cerbo GX.

[@zavnet]

This is very impressive!.. Wow!. I am very impressed and pleased with this!

[@alfredbportugal6914]

Very nice installation and all the IT settings. Well done sir

[@ProMace]

130 solar panels... I'm dying here. What an absolute boss. 😂😂🤣🤣🤣 Trying to figure out a modest AC-coupled ESS for myself. I'm really impressed with Victron's open architecture and documentation. En het is nog een Nederlands bedrijf ook! 😎☀

[@miketiong8441]

Good value for money.

[@dustinkatterbach9724]

5:17 is the top right battery not grounded by mistake?

[@VictronEnergyBV]

Well spotted! We have spoken to Bert, a battery needed replacing and they forgot to install the earthing before we arrived to film. Worry not, this has since been connected. Thanks for the heads up though!

[@rubomedicalimagingbv1905]

Impressive installation. However, I'm wondering about the 5510E dual circuit switches (2:44 min), rated at 350A, 32V DC. Is that not a potential risk/issue in a 48V system? Thanks

[@quickquote1568]

A wise choice to use Victron, low frequency transformer based inverter chargers instead of the many cheap, high frequency, transformerless inverter chargers that have flooded the market.

[@maxlentsoane]

beutifull house and with one of the best solar system you have, i wonder if you can have 10kv Multiplus Three phase or parallel system because according to specification its not possible, please clarify this for me please

[@yellownev]

A great home on an impressive Victron pylontech setup. Be good to see some smaller more affordable installs to inspire those who may want to step onto a home ( installed) pathway ?

[@VictronEnergyBV]

Noted. Thanks for the request.

[@gamingstudio1409]

I didn't think the multiplus 2 10kva was able to be linked for 3 phase

[@johannesboonstra6917]

yes it is, 1p/parallel isnt possible though

[@Ale55andr082]

basically all viktron inverters can be used in 3P. Parallel instead require specific models (!). Multiplus II can be paralleled (up to six units) but only in the 3000VA and 5000VA version, 8000/10000/15000 can't. So if you want a 20000VA single phase system with Multiplus II you must parallel four Multplus II 5000VA instead of using only two Multiplus II 10000VA wich is not allowed. The "QUATTRO" inverters are more versatile, they can be used in parallel even in the 8000, 10000 and 15000VA versions, so you can have high power single phase system pairing only two units.

[@herbertharry6137]

this is nice

[@mag.romanjanacek4523]

Very cool System. How is the combination of half AC and half DC realized, only with the 3 phased multiplus or are there any additionla inverters.

[@VictronEnergyBV]

There are some additional AC solar charge controllers

[@BluePowerPro]

At 3:37, where he talks about the big spike in voltage from the grid to 250V and how he solved this using ESS. I am unclear as to how exactly ESS solved this? Is he saying he basically went off the grid completely (thereby the spike to 250V no longer applies to him, or that he used ESS in some way to lower the voltage down to 230V?

[@James-op6ls]

Also interested in this. My understanding with the MP II is that the AC out we'll always be the same voltage as AC in, unless I'm mistaken? 🤔

[@BluePowerPro]

@@James-op6ls Yes when grid connected and not inverting, the inverter simply acts as a bypass device which means that its wouldnt solve the high voltage issue. My guess is that he went totally off grid and used ESS as part of that setup, Just not clear, as the way its conveyed, sounds like ESS was able to lower the voltages while still being connected to the grid

[@bramcoteelectrical1088]

You can alter the incoming voltage and out going voltages. I know of an electrical enginner that used smaller cable and at the end of the very long run had 160volts then input that into a multiples ans altered it to get the 230 volts 😂. Saved on cable and the current draw wasn't large just needed to save on cable and avoid voltage drop. Genius

[@timcx]

Very nice, do you have a link to the vlog you mention at the end of the video? Thanks

I’m living the same as he does , 10,000 square meters mansion completely off grid with a private deep well suitable for drinking also not far from the beach.

[@electro_solar]

Is there anything better than Victron, this is pure solar porn :D I live in Croatia, here we have more sunny days in the winter than Germany in the summer. :) This is my greatest wish, to have a off-grid house. Greetings victron engineers.

[@MitchOfCanada]

I would like to see a sand heat storage system for excess Solar Dump system that is used for hydronic heating and preheating hot water

[@nigelcharles511]

Great system, very envious. However like most of us using solar, he must struggles during overcast short days in winter. I say that because, if not he would not need to consider wind power generation. I have an off-grid system about one mile from home providing 20kw PV. This will keep two EVs charged for typically 9 months/year with excess to be exported by battery trailer to my house for about 10 months/year. I find that each EV consumes about the same as the house per year so it is a big challenge to be totally off-grid into the future. Last month, December 2023, was one of the worst months for solar for several years and it proved that even with 114kwh storage it was impossible for me to avoid taking any grid electricity during that month. Wind energy might be a way of making up the difference but at present small scale wind power rarely works cost effectively and is very dependent on a good location.

[@im_mark2484]

Well done Bert, I love seeing Victron used efficiently, its also a super neat installation, so credit to the installer, I would like ask if its possible to parallel the 10kw multiplus IIunit for single phase application as the spec sheet says it not possible @Victron energy

[@TheRonskiman]

I'm pretty sure you can.

[@irsalman]

I wish Victron would offer higher VA inverters for the 120v market to make use of the 450/200 mppt :(. I would happily buy it and give you any feedback or blog/video for your marketing I'm in the planning process of a 40kw PV, 90kwh lifepo4 and need 30kw of inverters.

[@johannes3-16]

Zolang de victron is gekoppeld aan het net is de spanning op out 1 toch hetzelfde als de spanning op de ingang?

[@edwinbruckner4752]

Mooi hoor, maar is 40kw opslag niet wat magertjes ?

[@VictronEnergyBV]

You may have noticed two other batteries either side of the racks, Bert is testing out some more storage solutions.

[@edwinbruckner4752]

​@@VictronEnergyBV Ah I see, I presume the storage voltage is 48V DC ? How does Victron see this for the future ? Will 48V be the standard or will we move to higher voltages, such as 72V DC ? The trend in most battery equipment is ever increasing voltages. We all remember the time when 18v for you battery powered tools was 'the future' , now it's gone up to 40 and even 60volt for such tools. How does Victron see this ? In my humble opinion I guess the same trend will apply for home energy storage. Or is there a good reason why we wouldn't see storage voltages above 48v ?

[@bramcoteelectrical1088]

48v is touch voltage safe so that's maybe that's why 😊 for end user type gear 48v is a safe option

[@edwinbruckner4752]

@@bramcoteelectrical1088 Ah, never thought about safety, lol. Yes, makes sense. I was more looking at it from a technical point of view. So yes indeed, for DIY stuff 48v seems like a safe limit. Maybe for the high end stuff more voltage makes more sense, maybe comparable to cars, or even trucks. You don't wanna be messing around with those cables.

[@bramcoteelectrical1088]

@edwinbruckner4752 100% I think it's great to use 350v dc stuff as you can power some very big systems just I think the risk to DIY users as you correctly said. Thank-you

[@margarita8442]

any deisel generators ? may have gone the quatro

[@VictronEnergyBV]

Burt doesn't have a diesel generator.

[@margarita8442]

is it off grid only ? @@VictronEnergyBV

[@RipsDiner]

@@margarita8442, when using a generator, i would recommend to charge the battery with another Victron Multiplus II 48/5000 and use this as a 48V-charger connected next to the other MPII 48/5000 and as a backup unit for the three other MPII 48/5000. the generator is a 1-phase-version ~4 kW continuous AC power with a blue CEE32-connector to the MPII 48/5000. the main advantage of this version is, that the voltage is constant like before and nothing of the system has to be changed.

[@bertelberse7005]

exactly what I was thinking about! Thx for the confirmation!

[@patrickmaartense7772]

im still happy with my 3x7KVA. due to the three cars the batteries are quite a bit bigger..

[@UmbrellaProject6790]

[@mflo1970]

Esta bien pero veo mas de 40kw de almacenamiento en principio luego otros 14kw en otro banco al lado

[@petertulp8806]

Why did a battery have to be changed in less then a year?

[@Fluxkompressor]

Grid Voltage normally is 230V +-10% so 207-253V. I don't see a problem with electronics there. Transformers will go into magnetic saturation at some point, sure but the capacitors in switchmode power supplys that get charged up to the peak AC voltage are usually 400V, so the AC voltage has to go up to over 280V to damage those. If some device fails at 253V it is not the fault of the grid but rather a crappy designed device Nice setup though. I like the fact that you can control all the victron products with basically anything using modbus How did you configure the system to prevent over voltages from happening? Does it disconnect from the grid if there is an over voltage?

[@VictronEnergyBV]

Well Bert can see the trend of the voltage going up and so he wanted to take precautions to protect his household electrical investments.

[@James-op6ls]

Also interested in the overvoltage protection

[@bramcoteelectrical1088]

Over voltage isn't good and just goes as wasted heat. Here in the 🇬🇧 UK alot of domestic products are from European countries and are rated at 230v and our supply is 250v +/- 10%😮but this over voltage is just wasted as heat 🥵 🔥 ☀️ so a nice lower voltage is softer on the power supplies and consumer electronics. 230 voltage ⚡️ ♥️

[@reedmurungweni2091]

This guy is from the Italian Job movie

[@MyGoogleYoutube]

So, when is Victron going to get into grid tied zero export stuff? Are you really going to let Sol Ark and EG4 run away with the hybrid inverter market? Pretty crazy they can make this system work with only 35kwh of storage.
