Eddi issues

We have solar panels and an Eddi a few months and delighted with them. Up to now the Eddi hasn’t been thought about much as our gas boiler also heats the water.
Now that our heat isn’t on we are using Eddi to heat water for two power showers. Our installer told us tank 1 was “sink” from old and tank2 was “bath”. We’ve run out of hot water once or twice after kids have had showers and I was curious to whether the tanks are maybe mis labeled.

Over the weekend I “experimented” and separately boosted each tank. When boosting tank 1the draw was 2.7kw and for tank 2 was only 1.9kw.

Would this mean that tank 1 is in fact bath and tank 2 is sink? I’ve changed the priority now to tank 1 but curious if that’s the issue.

Thanks!

Great, thank you!

We got a new tank that’s very insulated so it’s hard todo the old school way of checking by feeling the side of it.

I see it says it’ll heat tank 1 first on priority and then tank2, but that’s meaningless really if tank 1 is the full tank is it?

Great, thanks! Glad we’ve realised they were mislabelled before the summer is over and we would have thought the Eddi just wasn’t as good as we expected.

Hi

We have a gas boiler that we use to heat the water.

We recently got an Eddi with our solar panels and any time i've used the shower on a sunny day the water is luke-warm at best.

AFAIK the Tank 1 / 2 wiring (tank 1 sink, tank 2 bath) is correct but I'm wondering if there's anything else to check?

We have a power shower (with a motor unit in the hot press) if that helps (sorry I'm not very technical!)

Thanks

It was on for about 2 hours and seemed to pull around 3kwph.

It stopped heating it. I thought then it'd be hot enough.

Apologies if this already covered in the thread, but I don't now how to effectively search for a specific issue.

Tank one is immersion. Tank 2 is floor heating mat. I want eddi to ignore tank 2. Where in the settings is this?

After hot water is heated, I want surplus to be exported.

Edited to add.
There is no thermostat connected to the heating mat

Recently got solar panels and an eddi. Eddi connected to my immersion tank (It's a 2.7 - 3kw 230-240v
Heatcon model ELE-14-IN-800-FAB - must be 15 years old ish). Noticed a day or two after everything was set up and running that I'd get the warning triangles in the MyEnergi app and when I checked the EDDI box itself it said Fault code 48. Checked the manual and fault codes don't go anywhere near that high so assumed it must meant fault code 4 and 8 or possibly fault code 4 or 8. Fault code 8 made some sense in that the load was too high so I turned the EDDI down from 13A to 12A in case that was a problem. Sadly after a day or so, the same thing happened except this time it was fault code 47. 7 seems to mean to low of a load so I've put it back to 13A now and adjusted the Supply Grid Limit from 63A to 60A so will see how that goes.

Not sure whether it'll make it work permanently or not but figured worth a try before getting someone out.

Also, noticed that Local Comms Lost is a message I get every now and again too and when that happens the whole EDDI is frozen (no menus or anything work) so that's also got me thinking it's some kind of power issue where it either has too much or too little and it basically breaks the EDDI causing it to freeze and needs a reset to fix it. Could also I guess be the immersion or immersion thermostat (set to 60) causing it? I've tried setting the thermostat on immersion to 40 as well but same thing happened.

I have a Harvi so I think it's that? Harvi is down beside the Solis Inverter and the EDDI is up in the Hot Press beside the wifi router.

The EDDI is connected to WiFi (router is a few metres from the EDDI).
Harvi I assume connected to EDDI via RF is it? Would there be a certain colour blinking light or similar on the Harvi if it did lose connection to the EDDI?

Will do.

Although, the lost Comms every now and again is the least of my problems because Fault Code 47 is now appearing on the EDDI a few times everyday sadly. Will have to get someone out to have a look I suppose!
