Eddi issues

Hi all - got a 2nd Harvi installed today to monitor Solar PV and just checking whether it is installed correctly

... From what I can see when the panels aren't producing much at all ... the Harvi seems to lose power and the icon disappears from the app. The Harvi then has a question mark next to it on the Eddi ... indicating connection lost.

Is this normal/expected behaviour or has the clamp been put in the wrong place?

Not sure it’s a supply issue … when the panels are in full flow it’s still dropping the connection to the Eddi.

I have removed the Harvi from the Eddi ... and tried to re-pair.

When I press the button on the Harvi, it will flash blue to indicate the channel number. But it won't flash red to indicate pairing mode. It may not have enough power to go into pairing mode? (The panels are only generating about 0.5 kwh at the moment). Before I un-paired the Harvi only connects when there is a LOT of power coming from the panels. I thought the Harvi only needed 200w+?

Checking the installation ... the clamp cable is wired into the invertors AC supply - is that correct?! (photo below ... apologies boards put it sideways! 😀)

My eddi seems to be hanging a lot lately. I check it regularly and sometimes the unit will have the green light on or maybe one of the blue lights but the buttons won't work and the unit seems to be hung. If I turn off the switch and back on it works correctly but lately it hung again within a few hours. Any one else experiencing a similar issue?

Is it worth getting myenergi app. Have solar set up now for a month or so and used to Solis app.

Just realised there is one for the Eddi in the hotpress. Has been working fine although I think it drains the battery during day. ie consumption in house increased since battery installed and it seems to be eddi driving it when no other appliances on. I want to tweak settings but I cannot seem to connect to the device from the app as no reg number or SN on device.

Also WiFi won't connect/ no access point name visible etc. May already have been set up by installer???

Thanks for any advice

Try the Myenergi web login on a computer. I find it easier to read than the mobile app.

Also thank you!

Hi folks,

Thinking of adding the relay board.tp my Eddi..can you add two temp sensors if you only have one immersion? I was hoping to put one sensor at the bottom of the tank and one at the top

Cheers,

Mick

The relay board supports two temp sensors using PT1000 sensors. Where you are able to put them to get accurate readings will depend on your tank setup.

As the bottom sensor in my setup is below the immersion it provides no data for PV diverted data but is useful for information heating via gas.

Hi guys, still getting to grips with my new solar install and how it all outdated.

I've figured out based on the info here that my Eddi is currently set up as

Tank1 -bath

Tank 2- sink

System was set by installer to prioritise Tank1 -bath; wondering is this standard and recommended?

I was told it will heat first tank, then switch over to second.

I keep twisting the logic in my head and can make either make sense, but my instinctive logic was that it should be sink (which it would have been pre-solar), so that it will heat less water fully, before it considers heading full tank.

Also, I don't think "overflowing" power from bath to sink makes sense, as full tank would already be hot. Installer said, "yeh, but then you only need the smaller element to keep it hot".

I have an electric shower, so at the moment this water is only being used in tattoos around the house, I really don't need a lot of hot water on daily basis.

I've also considered discount the bath tank for now

Cheers. I think that makes sense.

At the moment, I don't really need it want a Full tank heated, so think it makes sense to stock with 'sink' where possible, and also to heat at 1.9kw instead of 3
