My meter was installed prior to my solar being switched on and inspected, but your mileage may vary depending on provider.

After engaging with disputes they arranged for the installer to come back and move the HW onto the same as the house at their cost. 

Now to give it a few days to see what difference it makes to my bill. 

Um, 

I rang them, got answered after an hour on hold, got transferred to accounts where I'm told they're in training and the call ends.

Hi all,

I’ve just had solar installed along with a Shelly 1PM to control my hot water cylinder. I don’t have a battery system. The solar setup isn’t fully commissioned yet and waiting for the paperwork and sign off, but I’ve noticed my power usage has jumped up considerably since the initial install.

When I checked my usage data, I found that my Controlled meter has dropped to 0 kWh, and instead all the hot water cylinder usage is now showing under Peak and Off-Peak kWh.

Is this normal when solar and monitoring devices are installed? Does this mean I won’t have a “Controlled” meter option for my HWC anymore, or is it just something that needs to be reset/changed with my provider?

Appreciate any advice from those who’ve gone through a similar setup.

I assume that the power company no longer have the ability to "control" i.e. turn off (rippled control) the HWC any more given solar install, so you no longer get that rate benefit.

Im guessing you had the meter changed? did you want the HWC to remain on the controlled circuit?

its likely where they have connected the HWC circuit, and so its no longer on the controlled circuit off the meter. They may be able to connect it back, or they maybe a limitation from the lines' provider about how it can be connected.

Worth talking to the installed about.

For what its worth, trade depot have a deal on a midea hot water heatpump at the moment for $1700 - I will be talking to a plumber about the costs to relocate pipes and going with that rather than worrying about automating my resisitve heater.

The midea app is tuya from what I have read so I assume that automating it by the app is going to be a lot easier than screwing with contactors on a resistive one.

Our SigEnergy system is all finally fully installed and signed off!

The installer put our HWC on a Shelly Pro2PM, not sure why a 2 as the 1 would have done the job.
That integrates directly with the Sig system so I've set it to only use excess solar between 7am-9pm and 9pm-7am (Cheap night rate) it will use the battery if that has more than 20% SOC, and once battery reaches 20% SOC then it pulls from the grid.

The Shelly is in the main meter box outside and they didn't have to do anything in the switch board in the house, except put a couple of stickers on it.

Power is with Genesis and they told me it would be $200 to get the meter upgraded for exporting but they were able to upgrade our existing smart meter remotely so only charged $23. 😁

Power bill for October so far is $35.  October 2024 was $283.

So when you get your quote/proposal its give estimate power generated and bill costs etc..  does everyone fine once installed these estimates are pretty accurate or do they inflate the numbers to make it look more enticing.

Do you know if the Shelly is driving a contactor or if it is directly switching the HWC? I'm looking at updating my old Mechanical Timer which is directly switching the HWC

It's directly switching the HWC and the Sig app shows how much power is going through the Shelly.
The Shelly is rated to 16A and the HWC is only pulling about 13.3.

I swapped my Shelly Pro1PM for a Shelly Ogemray  as I found the Pro1PM got quite hot under load (3kW element)

You can check the status of Shelly products  with say an ip address of 192.168.1.123 with http://192.168.1.123/rpc/Switch.Getstatus?id=0 and the temp is listed. Mine was getting up to 60degrees.

The Ogemray has huge terminals as opposed to the tiny Pro ones and obviously higher rated current.

That's why using a contactor is a good idea. The Shelley devices are great but what I've seen around geekzone is if you put a high current through them they fail sooner than you would expect.

I got three quotes, my usage is pretty accurate compared to the 3. Within 5%.
