In this video I explain what the MyEnergi Harvi is, what its used for and how to install and set it up.
Sorry for the video quality is not to the usual standard, seems the DJI Pocket 2 didn't handle focus or low light to well.

Thank you for the informative video Dale, it will definitely help me.. I’ve got my Harvi but I’m still waiting for my Eddi…. Oh and I’m still waiting for my ac inverter and battery storage, you know it’s so hard to try to consume the solar as it’s being generated. I’m only able to use about 45% of what’s being generated… if your not careful you could end up using more grid trying to use up the solar, I’m forever looking at what’s being produced and turning things on like the immersion heater and getting caught out when a cloud covers the sun. I can’t wait till I get my Eddi so it eliminates the stress and inconvenience, I’m new to solar (August 2022) and I’m forever trying to justify the worth of solar to the wife lol, I’m sure she will appreciate why soon enough… great videos Dale and I love to watch them especially the end of the month stats

Thanks Robert, I am going to be recording my 4 year update soon, so hopefully one of interest for you. Agree on the risk of hitting the grid in the fight to max out the solar but fighting the clouds, deffo handy when the devices manage surplus themselves, and of course battery storage. Thanks for watching and subscribing, means alot.

As you have a hybrid inverter you wont be able to put a CT on the battery, you will only be able to have the MyEnergi CT clamp on the solar and main income. Hope that helps.

Hi on my eddi everything was displaying but I needed to reset linked devices to get my myenergi hub working. Since then the information does not seem to be the same. Most of the time my energy house for the house is 0-1kw even when electric shower/microwave is on. What CT config should I have as that may be the issue. I have one harvi in my supply box and one beside my solar pv panels in the attic, thanks

@SpectrumGeeks Жыл бұрын

I am afraid I don't have any experience of a multi harvi setup, but I assume it would be the same as a singular one. So the CT clamp setting will be dependant on what feed the CT is connected to and selecting that in the drop down, and make sure the Eddi is looking at the device CT info and not the internal CT interfaces. Sorry but probably not much help on this one.

@MrKlawUK Жыл бұрын

what if you have two solar arrays and a battery? Am I stuffed? getting a givenergy battery and additional solar fitted but not sure how to get it integrated into the zappi so I can see in the app.

@SpectrumGeeks Жыл бұрын

I am not an electrician or approved solar supplier, but this is my opinion :) So if you have two solar arrays and a battery the easy option is you only have one array monitored by the MyEnergi devices (I would choose the larger array), and basically just rely on the grid CT clamp knowing there is a surplus going back to the grid as this is really what it cares about for using surplus. If you have multiple solar arrays and batteries and you want the MyEnergi gear to fully understand what the solar generation is and whats being provided by the batteries, I would suggest having a seperate consumer unit that the solar arrays are in and another for the batteries, and then put the CT clamps on the tail feeds into the main consumer unit. Then the MyEnergi device will see ALL solar generation regardless of array and all battery provision of power. This does add to the cost, complication and space, but thats probably the best way to do it. I am not sure if you could just put a CT clamp on each array live feed and connect to the same CT terminal, but I could imagine this could work but also cause problems. This is all hyperthetical, but as I have thought about how I will tackle this scenario when I add more batteries and solar, I have given some thought, but not done it.

Yes PV panels are not required, but the Harvi does need another MyEnergi device to interact with (Eddi, Zapp, Libbi). So depending on what you are trying to achieve this may not be the best solution.

What is a AC battery? And how would you make the Myenergi to ask my Growatt to discharge my (DC) Battery whos connected to my inverter??

@SpectrumGeeks Жыл бұрын

The MyEnergi Harvi works with MyEnergi devices such as the Zappi, Eddi and Libbi, so not something thats going to help with your Growatt Inverter and DC batteries communication. AC battery, is Alternating Current Battery is simply a battery that has the inbuilt inverters to provide power to the grid / your house. So slightly less efficient than a DC battery, but more flexible in my opinion.

@IpFix- Жыл бұрын

@@SpectrumGeeks - Thanks for the reply :) Actually I’ve never heard anyone call it a AC battery, since it is a DC battery, but I get the point 👏🏽 For me to draw form my house battery I would need something to tell my inverter(who control my battery) Do withdraw power- Still I’m pretty sure I will buy the zappi 👏🏽👏🏽

@SpectrumGeeks Жыл бұрын

@@IpFix- There are AC connected and DC connected batteries. Regarding your issue, the inverter connected to your DC battery should have a CT clamp to see when power is coming from the grid, and instead supply the power from the battery. Similar to solar panels, which produce DC power, batteries store and produce DC power, as well. Because the electricity in your house is AC, this means the batteries inside devices like your smartphone and your laptop need to use a converter to turn the AC power coming out of the outlet into DC power so it can be stored in their respective batteries. Home batteries also store and produce DC power. The main difference here is a DC battery will use the same solar inverter to convert its stored DC power into AC power, whereas an AC battery has its own built-in inverter allowing the battery to directly convert its stored DC power into AC power to electrify your home devices and appliances.

@mrjohnmeredith Жыл бұрын

Great video (although you need to focus the camera a bit better ;-)). I take it that you extend the Solar and Battery in order to only use 1 Harvi? Otherwise you'd need an additional one or 2? My setup has a Powerwall and Inverter in the garage, while the Tesla "brain" is near the incoming feed to the house, and hardwired via a trench run to the garage. The installer suggested 2 Harvi for me?

@SpectrumGeeks Жыл бұрын

Yeah I used the DJI Pocket Cam with this video as was all I had to hand, and the focus was shocking :( Correct, for the solar and the Tesla CT clamps I just extended them with a single ethernet cable using four of the strands. Its about a 25 meter run, but all been working fine for four years.

Great video Dale I'm new to all this I've recently installed 6kw panels Fox hybrid inverter and 10kw fox batteries they are all working fine however my eddi is not! It draws power from the grid when it shouldn't and says waiting for surplus even when my battery is full and I'm exporting the Fox app has different reading to myenergi app. I've got 2 CT clamps ( maybe I need 3 not sure ) CT 1 on meter tail arrow facing the grid and set to grid on eddi. CT 2 clamped round live wire after isolator AC ( after battery ) again facing towards the grid and set to generation and battery ( I've tried generation only didn't do anything different ) both hard wired through cat5 cable. Can you advise on how many Cts I need ? And what setting I should have on the eddi? Its driving me mad I've searched the net to see if anyone has done a video on how to set eddi up in detail for different configurations but I cant find one. I'm hoping you can help me? PLEASE.....

@SpectrumGeeks Жыл бұрын

Few questions. Are you using a Harvi or do you have the CT clamps wired directly into the Eddi? Are the batteries AC or DC? You say CT2 is facing the grid, do you mean facing out of the MCB its connected to?

@davidjaynethomas4668 Жыл бұрын

@@SpectrumGeeks CT clamps wired direct into eddi DC batteries my inverter and batteries are in the loft CT2 is connected to the live wire that leaves the loft going to consumer unit 5mm cable I striped cable back a bit so I could clamp the live only. I have 3 isolators 2 xDC and one AC this is where the 5mm cable leaves the loft and goes off to consumer unit hope this all makes sense. Sorry for the delay I stripped the sump bolt while servicing my bike so I had to sort that first.

@SpectrumGeeks Жыл бұрын

@@davidjaynethomas4668 Yeah I think I have a picture of the setup, so CT2 is on the same feed back to the consumer unit for Solar and Battery, hence generation and battery being set. I would say this sounds like its setup like it should (aside from the Eddi really knowing you have a battery). When you look on the Eddi at the CT clamp readings, can you see the expected information, as this will be what the Eddi is making its decisions on. i.e when it says waiting for surplus, look at the CT clamp readings, is it not saying there is a surplus?

Hi Dale. I bought a Harvi and 2 clamps managed to connect the cable from the clamps but when I put the cts for solar and battery I don’t see any readings on my Zappi app. I positioned them on the same cable as my Zappi clamp (the inverter clamp is also on that wire) with the direction arrows pointing to the CU. But no readings on the app. So am I using the wrong cable for my two new clamps?
