DIY Off Grid Three Phase Power - Part 2/2 | ØY27

Have you seen the prices of electricity lately? Well, this customer was paying over £35,000 just for a SECTION of their home 😳. It was a pleasure to work along with Lemon Energy on their job to get their client a full ground mount victron system along with Lemon Energy batteries to get them off grid, and down to zero import!
Greenwashing, or the future, what do you think?

[@mfx1]

Just FYI LoRa is a system that uses a bandwidth, bitrate, range tradeoff. By using a very narrow bandwidth you reduce the bitrate you can transmit but the energy is more concentrated so it can travel much further. You can usually use it in mesh or repeater modes to further increase range.

[@sarahjrandomnumbers]

Did some tests with LoRa a while ago, it's stupid insane the distance you can get with the super slow modes.

[@Crazydiamond_1974]

Hey Cory, great video and great installation. My comment is about the solution to the client’s requirements, not the electrical installation I have a pool, probably a similar size to that one at 50,000 litres. I got a 13kW ASHP for around £2k and got it installed for £300. It pulls maximum 3.5kW including the circulation pump. I run it for 3 hours at night and 3 hours in the afternoon (when solar power and solar gain are optimal) and the pool temperature is set at 32 degrees. My point being that this really is using a sledgehammer to crack a nut. Obviously I don’t know anything about the rest of the owner’s property load which may justify the system, just commenting on what I see

[@corymac]

This house regularly exceeds insane baseloads , more than 20x the average house hold. Also, you can profit from electricity export

[@Crazydiamond_1974]

@@corymac ah yes, you’re preaching to the converted there. I’d love to get my upgrade to 11kWp completed, but the quotes are just too much for me to justify it

[@vess.stanev]

Great to see you back in action, Cory! Great content as always!👍

[@ChrisShucksmith]

Seems very odd design to be dropping £40k+ on battery storage to then run resistive (CoP 1) heating of the pool. Would be far more economical to have bought two less battery packs and replaced the oil boiler with a ground or air source heat pump! That would have improved the COP of the whole scheme immensely, which would have brought significant savings during marginal sunlight days, when the immersion heater load exceeds the generation capacity. Questionable system design but nice execution.

[@corymac]

Theres a lot more solar going in, and the pool plant shall be brought into the designs for this as currently, the pool controls are out of our remit.

[@dansonamission]

[@Christopher_S]

I've been looking forward to this follow up video for a while. I'm glad the day has finally arrived! :D

[@MichaelPickles]

I thought, with 46,2kW of solar power that would exceed that victron bus bar? Victor setups of that size tend to have bigger copper bars. I put my 16 batteries in parallel pairs. Each pair has 52v / 250 amp fuses. With the load of turning on those 15 kva inverters you want each one on a on/off switch The copper coils in them will trip breakers if you do not. So I have one combined p 3 way 500amp each main breaker on the positive side for emergency off. Then 3 negative DC breakers. So when I'm doing a battery boot up from cold it does not trip the batteries 100 amp internal DC breaker switches. With the size of that room you should put some foam blocks between each of the inverters to stop the downdraft of heat when their own full power. Otherwise it tends to recycle the heat. It won't help so much once it's filled the room with heat.

Nice job. I guess the house has a massive electric bill so A) keep money in bank and pay tax on interest. B) do something cool and have nothing much to pay for the next 20 years. I’m now getting bill that are basically standing charge + half the EV charging costs (7.5p rate). Even on a cloudy day that rig is going to generate enough to run the house and pool. Might not have enough to top off the batteries though.

Just looking at your video and the wiring. As far as I understand all DC should be the same length for each element. Ie inverter cables must be the same length from phase 1 to phase 3 unit. Battery cables must be same length from further away to closest battery. But it doesn’t look like that has been done here?

Could you use the wireless transmission system you used in a domestic setting to switch on an air source heat pump for hot water when you have excess solar production?

[@grahamek86]

So those struts in the ground with the grub screw type fasteners ... what's going to happen when the weather heat cycles them? Surely they'd be best to drill through the inner strut so they're not just "clamping" but actually supporting? Or have I understood this wrong?

[@corymac]

We’ve followed the instructions and design of the manufacturer, but I think you raise a valid point

[@grahamek86]

Thanks for the reply. It's possible that the correct torque will create locating "dimples" in the inner shaft, but my initial worry was that the heating and cooling would loosen them off. Hopefully they'll all move in unison and not damage anything if it does happen - it's a bloody cool array and the plant room is a techies "gentlemens club". Love the quality of electrical design and craftmanship that has gone into it. NB I tried to view the VRM installation online but got an error to say I don't have access...I presume the owner has removed public read-only? @@corymac

The cost of the panels,inverters,installation and storage must be added together and divided by their expected life span, to give an accurate cost per year. Even the land used to mount the solar panels is a cost. Dont get me wrong, there is a lot about this install that is very good, even excellent from an equipment point of view.......but it is not free, it all costs $$$. Myself, living off grid for 5 years )) We had a large battery storage LiPo (not ion) storage facility near Rockhampton Australia catch fire recently.........DO NOT put your lithium storage in the same room as your inverters......thats asking for trouble. Put them in an adjacent fire resistant room.

[@xNYCMarc]

@@corymac Daylight IS sunlight.

[@corymac]

Daylight is the combination of all direct and indirect sunlight during the daytime. This includes direct sunlight, diffuse sky radiation, and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings.

[@xNYCMarc]

@@corymac Right, but it all comes from the sun. There isn’t a separate source of light. It’s silly and disingenuous to suggest that “daylight” is somehow not sunlight. If the sun weren’t there, there would be no light to reflect or diffuse. Also, direct sunlight on panels produces more energy. I have 29kw of panels on my roof and have had them since 2015. Panels in shade produce less than 1/3 the energy of panels in direct sunlight. I’m not really sure if you’re advocating putting panels in shaded locations. But it’s WRONG to do so if there is an unshaded location available.

This whole field will be covered by the end of next year

Great content Cory. A WiFi link to the house would give much more flexibility for future automation/contactors, etc. If using Node-Red features of the Cerbo GX, along with being able to track house energy usage with something like EM24, EM540, or one of the new Victron meters due to be released soon. Is there a reason you are avoiding this kind of integration? Does this setup require a G99 application?

[@LemonEnergy]

Whilst it operates off grid there is no requirement for a G99, the ultimate goal is to have it connected to sell back excess power however we are still waiting on the DNO to upgrade the supply. There is a fibre link back to the house for communication, the wireless switch was used as a quick simple way of diverting some of the excess solar into hot water. The ultimate goal is to have the whole house moved over to air source heat pumps with full zonal control and integration with the solar and batteries via Loxone.
