Disconnecting This House From The Grid | ØY11

It's not every day that a customer asks you to work on an off grid system they've practically designed and installed themselves! But I think he did a pretty awesome job! In this episode we take a closer look at what is in my opinion, one of the best off grid battery systems on the market right now - Victron. Along with Ted, we get the system up and running as well as vertically mounting some solar panels on the property. It’s an unusual solar and battery storage setup, but we feel it’s worth filming! Comment below on what you think of this DIY solar setup! Enjoy 😄

Hi Cory. We do a lot of Victron Invertors/ solar and battery systems over in Nigeria, and I'm originally from Cambridge, so I was loving the Jollof video you released a few days ago, What I would recommend is that for the Invertor connections and the fiddly connections, use tri-rated cables for their flexibility and ability to use smaller CSA for the same current rating as standard cables. Also use ferrules on all the flex/ tri rated cables that you connect.

[@corymac]

Thanks for the info! Check the newer videos, I’ve found better ways since this video

[@Leksi80]

Great to see other people doing this kind of creative setups as well. I am planning on installing 3 x 48V/5000VA Victron Multiplus II 3 phase setup in Finland with 30-60kWh of LiFePo4 battery bank in my house with already 2021 installed 11,2 kWp solar system on the roof and an EV-charger for the car. My dream is to also feed the 10kW Fronius solar inverter with the Victron inverters so that even if the grid fails, my solar production does not and the house is then running on the battery bank with 12kW max load. Thanks to Victron, that island function is literally a life saver(for grid installers) and in here, the regulations allow that finally. Also the added benefit is that I can charge the batteries from the grid at cheap night tariffs(at 9kW charge rate) during the winter nights and save quite a bit during the daytime consumption even when the solar is not working because of the snow. Just finding the right sparkies for the job is being a real pain. Love this kind of content. Keep it up mate =)

@@L81ker From what I have seen, the solar disconnect is on the wrong side of the mppt, the fuse is also not needed on this side, should be on the other side (solar panel side).Cory did mention connect the load on AC2 but connected in AC1 witch is the good one (uninterruptable).That's what I did see in the quick peek that we did see a close up on your system that what i did see

[@L81ker]

hi @Steve, Thanks for your observation, all the comments are valued and appreciated! The two solar disconnects are on the panels side. One in the loft inside the wall the panels are on, and the other above the mppt. The cables at the mppt are not right yet. We need to figure the layout properly. It's not a circuit connection problem, but a mechanical turn radius one on the solar cable. Any suggestions here are welcomed! The battery side is switched and fused (40A)... fuse protects cables, switch is to isolate for maintenance and service etc.

[@MichaelPickles]

You hit a nail on the head! I cannot find an electrician that will take on jobs like what you are doing. Because they are not profitable for them. I understand why, that's fine for them.

They are one way valves for electric current to prevent reverse voltage flow during transient events such as switch over to island mode (unlikely in this setup btw)

[@mattshadwell949]

I live and work in Zimbabwe where currently utility power is available between 4-6 hours a day in many parts of Harare. Victron is very popular here but is a premium product so a good price competitive alternative with similar functionality is the Sunsynk/Deye inverters. They are very popular in SA too. Well worth checking out for domestic applications like this and being an all in one unit it makes wiring and setting up a bit easier compared to the victron system.

[@corymac]

That’s cool!

[@xxwookey]

The Sunsynk kit is good, but the architecture is not open in the same way. Sunsynk will give you no help at all controlling the system locally, as opposed to via an app to their remote servers. There has been some reverse-engineering of what can be controlled over modbus, so it looks like some local control is possible, but still quite uncertain what does and doesn't work. If you actually want control Victron is streets ahead. If Sunsynk/Deye would just open up a bit they'd have a great product. I looked at both and was quite keen to pick SunSynk because it's cheaper, but decided that Victron's openness and flexibility meant it was literally the _only_ supplier that I could choose. Everything else is too locked down, and some of it isn't very efficient either.

It's nice to see panels installed like this. Maybe it's not perfectly efficient year round, but they will still get some good energy for some of the day and for some of the year

[@corymac]

I agree! Thanks

[@matthewwakeham2206]

It gives a more consistent power output throughout the year and can/will outperform roof mounted panels in winter. Also the panels will be generating power earlier in the day when you are more likely to be using it. Even if you can't use it, it's recharging your batteries early on in the day. It will give less annual power than a roof mounted array but more power in winter and the annual difference is not as big as you might think. A mix of both would be optimal.

[@WarwickIsSensible]

A quick clarification - AC Input 1 loads will automatically be backed up on grid failure and the default behaviour of AC Out 2 is to disconnect the output. It is programmable, though.

[@Electronzap]

That's a nice setup he has got. I think that a lot of people should be partially off grid. Have the bare minimum be powered with solar and all the extra stuff powered by the grid. If the gird goes down for whatever reason, you won't be bothered much.

Solar installers incentivise with big 'rebates' but the end-user doesn't get the renewable energy credits - the installers do.

An interesting setup, used loads of victron stuff on boats and is well built and designed well. Interesting system design, I assume when they have a power cut will still have to go to the second consumer unit and manually change the changeover switch? If you hooked the multiplus up to CU1 and then used the output from the victron to power CU2. That way the Victron multiplus can do the changeover automatically to battery power for you?

As far as I can see I would do it the same like that guy: design and do most of it myself, and let the certified electrician check my work (pure copper, cable width, etc), and do the really scary stuff like connecting that one inverter to the uplink. For my the idea is to go full off grid and in the future feed back to the grid during grid peaks.

[@John_vDongen]

A diode is a one way pass though shunt, also used to clamp reverse voltages from straying back to the solar panel. It isn't uncommon to insert one at every panel, just in case one shorts out... Though the reverse bias is around 0.06th of a volt. Diodes can also be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators. The fundamental property of a diode is its tendency to conduct electric current in only one direction.

[@JC-jv5xw]

Surely if you are mixing two strings using passive diodes, in almost all cases, due to tolerances, one string (with a marginally higher voltage) will be providing the power and the other will be blocked. So you are only ever getting half power from the array?

[@sdgelectronics]

No, because the voltage on the panel decreases with load. The diode doesn't block the array from outputting power, it just prevents one of the arrays being reverse biased.

[@JC-jv5xw]

@@sdgelectronics Thanks. Sorry I was thinking from a control signal perspective, where you combine two signals with diodes to get the higher voltage. Very high input impedance so minimal load currents involved.

[@black.phoenix.]

@@corymac rack mounting was how remote mobile telecom switching centrals had redundant energy if the main power failed. When I worked in telecom I had to test that system every year twice. Basically it had main power, in case of failure a system of 2 inverters and 48 prismatic gel batteries would support the central until the diesel generator (that was a volvo truck motor inside) would kick in after a minute of battery power. By itself the batteries could support the switching central for 4 hours and the generator had an extra tank of 10000L of diesel just in case. Funny thing is that that amount of diesel was needed once when a big power cut kept the region in blackout for 2 days. Unfortunately that central was decommissioned back in 2014.

[@konnradbanaszewski]

Well Done ! This is a well designed system. Especially the idea to install solar panels vertically to take most of the winter sun.

[@corymac]

Thanks mate! I can’t take credit for the design, that was Clive 😄

0:29 I reported a "Brown Out" once to the NDO.. The girl on the other end of the phone was clearly not thinking of the power.. very strange and awkward call :D

[@buixote]

Dunno if Growatt have made it to your neighborhood. I'm running a pair of ES5000s for 10kW of "inversion". The Rack has 30kWh of LiPo. Not enough sun for Solar here, but we can charge, off-peak. Unfortunately we're currently using a manual transfer switch... Since the Growatt can choose the source, we're thinking *that* will be the primary control, and that we can find a transfer switch to use the Grid when the inverter shuts off.

I’ll have to check that out

Great content Cory. Very interesting project to work on.

[@corymac]

Much appreciated!

[@ForTheBirbs]

Another awesome video Cory and Ted! I'm loving the extra tech stuff. Is the change from current clamps to a true VA meter a general rule or just for the Victron gear?

[@corymac]

Thanks Jim!!! I believe it’s just Victron right now 😃

[@ericmcrae7758]

That was a beautiful piece of brickwork I bet the brickie was upset you screwed some panels over it.

[@corymac]

It was dead straight actually

[@samjburns07]

Great video mate - I've got a question. In Feb I'll be doing work experience for an electrical firm and I'm hoping to get an apprenticeship with them, have you got any advice? Cheers

[@corymac]

Keep your head down, soak it all up and be prepared to work long and hard 😄 - there are no shortcuts

[@samjburns07]

@@corymac cheers, will do!

[@BradCagle]

I do a lot of solar, and battery reviews on my channel. Victron gear is by far my favorite.

[@corymac]

It’s pretty cool kit!

[@siredward782]

The 1.5x power to battery capacity minimum only applies to AC coupled PV, if your PV is on Victron DC MPPTs that doesn't apply.

[@corymac]

Ahh interesting! Thanks 🙏🏼

[@lars-akeclasson875]

And you can run the inverter without any battery connected, i.e. inverting from the Victron MPPT(s) is always possible. good video!

[@L81ker]

Although that is not a good idea because if this particular 150/35 mppt (35A) is connected to solar but not to a battery, it tends to let out the blue smoke and not want to play anymore, and could fail in such a way as to pass all the solar string voltage at full current directly to this 48V Multiplus 2... Could be an expensive decision.

Thanks dude! 😎

[@daves4026]

Awesome video. Totally get the linux metaphor that was helpful

[@corymac]

Glad it helped!

[@seymourpro6097]

Victron do an absolutely fabulous book "Energy Unlimited" going through every combination of systems from small sailing yacht systems to bigger house systems. Even better it's a free download in several languages (as PDF) from their website. It may now be dated because technology is developing quickly, but it's a perfect primer for anyone wanting a good introduction.

[@corymac]

Thanks mate! I’ll definitely Look at that

[@manwithnovan]

That's a big one job.

Guessing his photo frame controller was maybe a Nextion programmable smart screen. I've used them for a few things.

[@corymac]

I think it was a version of this yes. A raspberry pie controller screen

[@HSilver341]

Top vid we got Solar panels from the fit tariff we don’t get anything in payments ,but we got analogue meter still which is a billy bonus will a victron set up (I.r batteries)give me anything more

[@corymac]

It won’t create more power, the solar or other generation type will do that, the inverter will simply invert what is created into a useable and stable current

[@HSilver341]

@@corymac I get yer but surely a analogue meter going backwards when solar is generating lol is on par with battery storage or is the batteries saving more of the energy ,last summer my meter must have gone backwards about 10 units per day on the good days

[@Rfhdvcgf]

Hey I installed an off-grid system myself with 2 redundant inverters and 2 arrays just to get independence from the shitty unstable grid where I live

[@corymac]

That’s cool!
