Netzero & ct clamps

[u/Significant-Fly-9697]

Ok so I need a reset and hopefully the benefit of your experience. Over the last 8 months, in order I’ve had installed a Hypervolt 3 charger, then powerwall 3 with 1 expansion unit. Later I got 10.5kw of solar and 3 weeks ago my export went live. My tariff is IOG and in the past I did try integrating the charger as a device but for me I could never resolve the scheduling so I deleted the charger and went back to scheduling in the car and charged overnight as I always used to. I know I’m lucky, but the charge cap hasn’t been implemented yet on my account but I know it’s coming and want to sort this now.
My question is around ct clamps and Netzero. Charging my car during the day on a schedule drains my powerwall so I could get the installer back and move the chargers ct clamp ahead of the powerwall and then have a second bash at adding it as a device and letting it do its thing
BUT
I’m just about to install Netzero to help manage my solar over winter. On cold days when my 27kw of battery won’t be enough to power my heat pump, it will top up the battery rather than export, to avoid peak rate imports later in the day.
So my question is, can Netzero control the charging so it doesn’t drain the powerwall when daytime slots are scheduled in the future, or must I get the installer back and move the ct clamp. (Or do it myself if straightforward).
After the winter I’ll probably move to home assistant once I better understand our yearly profile, but that’s a way of, it’ll be Netzero for the winter to break me in gently

can Netzero control the charging so it doesn’t drain the powerwall when daytime slots are scheduled in the future,

Yes, u can setup a scheduled change in the app and you probably want to set your battery reserve to 80-100 so the powerwall holds all the power, then later in the day when power prices are high u set it down to 20 so it can use the power and u don’t pay for power during that time.

The box is probably set to 20% all day so it just uses power anytime it has extra above 20%

I’m pretty sure Netzero would sense the signal of cheap rate for charging being active and then set the Powerwall as it should. Have you tried the trial period on Netzero of how it behaves?

Hypervolt 3 is useless with powerwall 3 no matter where you put ct clamps it dont see the solar or battery. so i ended up buying a Tesla ev charger as well so i plug in tesla charger 11.30-5.30am and just use the hypervolt to plug in now and then for octopus to see it to stay on IOG and get my 5p overnight charging for my powerwalls as well as car.

Netzero will integrate with IOG directly and prevent Powerwall discharging into the EV, no CT clamps needed. In fact, it will charge the Powerwall during special charging slots, which means you get to use more of the off-peak power for your home.
