Thanks Mark, yes I am with your dealer, well done you getting your order in so early; I am reassured to know those being delivered were ordered well before ,me and that you are happy with your purchase. I spoke to a guy today about installation of a three phase zappi charger in anticipation of a delivery sometime this year. I guess as you say it all happens quite quickly when your order falls due!. Would be interested to know if you have installed a smart charger?
Cheers, Loz
(It's Robert, actually, but all good!)
I had some interesting experiences with installing a charger. In January we were considering upgrading our solar system to add a battery, which we did in early Feb, as well as adding another inverter. So we have a 19.8kw 3-phase system, an 11.4kw battery and aren't capped out at 15kw generation anymore (though that's still our export limit at any one time). At that time, we discussed adding a three-phase charger knowing the car would be coming at some point. I had followed the Zappi's progress via the Fully Charged Show's excellent YouTube channel, but my solar man (who we like and knows what he's talking about) wasn't impressed with the device or the local support. So we left it up to him when we eventually ordered the upgrades and plumped for the charger at the same time.
The charger he installed (weeks before the car arrived!) was an Ocular Home three-phase unit. Since we were all somewhat uneducated, we assumed the setup would allow either the inverter metering or the car itself to regulate the charging speed (to hopefully use only excess solar). But actually when the car arrived, we discovered the Kia's charging amp reduction settings don't seem to work on 3-phase charging, so we're stuck charging at 11kw no matter what our solar generation.
Before the car arrived, I had signed up for ChargeHQ's beta program, which should manage the solar/grid consumption nicely... only to discover that the Ocular Home isn't OCPP compliant... so that option was already out.
I asked our installer to swap out the charger for an Ocular IQ smart charger (car arrival imminent) and he started out on some research. He came back to me recommending the Pulsar Plus (a global company with an ex-Tesla employee as one of the founders I believe?), and my own hunting around seemed to show it's a decent quality device and has a smart meter to monitor solar use (not charge clamps like the Zappi), as well as a "use green energy only" eco setting like the Zappi. Possibly with this arrangement, I wouldn't need ChargeHQ at all (though Jay had confirmed the Pulsar Plus will work), except...
... the Pulsar Plus eco-smart green only / use excess solar only setting also sees our home battery as "green energy" and will draw on it if we don't have 11kw full solar excess. That can work, as if I charge early enough in the day and a few clouds drop solar output, then the battery buffers that and gets topped up later in the day. Still nothing from the grid, unless it gets really cloudy, as the battery will top out at 4.8kw demand. But not ideal. And neither does the Pulsar Plus's "reduce charging current" function work if using the "eco-smart" settings (works perfectly if all energy sources incl grid are used though).
At this point, I was feeling a little stymied by every option, so decided to test the ChargeHQ management app. I put the Pulsar Plus into OCPP mode, entered settings and it all looks fine... but you guessed it, nothing happened! The charger stays locked, and ChargeHQ says "starting."
But a happy ending shouldn't be far away, as in my to-and-fro correspondence with Jay at ChargeHQ (who is fantastic! Shout out to Jay), we have discovered a non-standard authorisation setting where the Pulsar Plus in OCPP state defaults to an unauthorized state (ie the charger is locked) until the OCPP operator sends a signal, or the local device is unlocked with an RFID card or other payment system (this charger is also aimed at multiple installs where paying for a charge is available).
So in the next day or so (I hope), Jay should have a fix where the Pulsar Plus will be sent a remote "AuthEnabled" ping that should then remove my final obstacle.
So this is a long explanation to say that not all things are equal, or work as expected, and I've learned a lot about how this all works. And now have "Tesla app envy" as this type of setup is a cinch with a Tesla (ChargeHQ integrates directly with the Tesla app). Kia Australia have really dropped the ball with no Kia Connect installed (apparently model-midlife refreshes and new models are supposed to have it from late this year or early next). Controlling all of this from an app should be the norm in this day and age, esp a cutting-edge EV. When we test drove the Model X a few years ago in Brisbane on a baking hot day, the salesman had the aircon already running remotely from his app. Technically the Kia can do this if plugged in and on charge and with a departure time set, which is already a bit basic, and even more so if you can only set that up from inside the car (ie no app to configure it remotely). But these are early adopter issues (or first world problems!) and we still love the car, it's the best we've ever owned
