Evnex working on a bi-directional EV charger

Here is the latest update from Evnex on a thread in their community forums:

>Yes it’s still on the horizon.

>Sigenergy and similar “ecosystem” players have the luxury of being able to “hide” their bidirectional charger behind their battery. This means that the battery inverter is responsible for meeting all of the required standards for a grid connection, and the charger is really just connecting the car battery to supplement existing stationary storage.

>We prefer the model where standards are handled by the charger and car, because that means it can be installed in any home regardless of what other hardware already exists (and which brand / ecosystem it might be). This makes it a truly universal product which anyone can buy and know it will work.

>Of course that means that things take a little longer, but we think it will be worth the wait to keep things as simple as possible for drivers.

No update on when exactly we are likely to see this come to market.

Original thread: https://community.evnex.com/t/bi-directional-ev-charger-vehicle-to-home/46/19

I currently have a Sigen set up but I would prefer an Evnex solution. I had an Evnex charger installed when I purchased my first EV back in 2024. I got solar installed in late May this year but the set up of my house means my inverter stack is too far away to be useful for getting the DC charger.

SigenStor discharging to the load at a very low rate

I have the battery set as a priority to discharge before grid during peak import times. Yet the battery is only discharging at 0.2kw, yet the importing from the grid is at 1.5kw.

Have played with some settings but nothing changed, set them back to default.

Just wondering if anyone know where this limiting setting could be?

Ecotricity | ECOWholesale

I'm looking at moving to ECOWholesale, but trying to get any information out of Ecotricity is like blood out of a stone.

They're telling me there is no cost over and above the spot price, apart from the usual daily fixed and network charges.

Can anyone on the plan verify this is correct? Seems too good to be true.

Solar and gas (as piped gas enjoyers) or time to go fully electric?

We have a 7 year old house with a 4.15kw PV system, no battery. Someone usually home during the day. We're trying to work out if it makes sense to stop having piped gas as the double daily charges are a pain and we know we're not making the most out of our solar, but we enjoy some aspects of our gas appliances. Have other people made the jump with similar barriers? Any advice?

Our piped gas is used for the stove top, infinity water heater and a double-sided fireplace. 

We have heatpumps in the house for the bulk of our heating, but we do turn the gas fire on occasionally in winter because it's nice and we're paying the gas daily charge anyway. The double-sided fireplace really made us fall in love with our home. It's in a open plan area and gives it a nice ambiance. I haven't been able to find double sided electric alternatives, so I'm thinking we could just cut the gas and leave the unit in the medium term, or install a single sided electric one bit it would lose some of its appeal.

We love to cook and enjoy some aspects of gas cooking (specifically using our wok a lot and some non-induction friendly cookware). We appreciate that induction has benefits too, such as speed of boiling and much easier to clean up the stove. There's a neither-here-nor-there idea that we could get a hybrid stovetop which uses LPG bottles (bottles owned rather than rented) for one burner and induction on the other burners.

I suspect we'd be able to get an electric hot water system outside where the infinity system is and be able to put a lot of our currently exported solar power into that. I think it's slightly undersized for the house but it's not a big problem for us.

Any advice? We've worked out it'd cost a lot to convert everything to electric, especially the fireplace. And it will pay itself off eventually but by my very rough calculations it was over 10 years. The appliances are still working fine so not needing replacing yet in that respect. I've joked it'd be easier to get some more solar panels and a battery and cut off from the electricity grid instead!

Genesis power shout -sig

To effectively use a genesis power shout - 1 hour free power scheduled

Is the best way to use Sigenergy “instant manual control” and set it to charge for that hour.

Any other house usage will come from grid? - and Solar if there is any?

Or is there a better way

Aiko vs JA panels

Getting solar installed through Harrisons and was wondering peoples thoughts on the preference as aiko are about 120 more expensive per panel. Is it worth it as big purchase and dont want to regret it either way

Ecotricity: ecoSOLAR vs ecoWHOLESALE

I’m considering switching to Ecotricity. I currently have 13kW solar + 9kWh battery.

Has anyone been on Ecotricity’s wholesale plan (or used it in the past)? Did it work out better overall than their solar plan? I know pricing can vary by region, but I’d still love to hear real-world experiences.

For context, I’ve been tracking the spot price for my local network node (HAY, picture attached). It’s averaging around $0.10/kWh, with lows of $0.01, highs around $0.20, and a few brief spikes up to $3-4/kWh on some of the colder days recently.

I’m trying to work out whether it’s actually worth micromanaging grid consumption to avoid importing during those spikes if I go on wholesale, or if a flat rate of $0.18/kWh (for generation only) under ecoSOLAR is overall less hassle.

I have Home Assistant set up, so I can manage charging/discharging around the spot price; I just don’t know whether the effort is worth the hassle.

If you’ve tried wholesale with similar conditions, what was your experience? do you recommend it?

12Kw solar + battery setup. July power bill $630.

We’re with Ecotricity on the eco solar plan. We’re in N Canterbury on Mainpower so daily line fees are stupid, flat rate of 26c for import. Spa pool running on eco mode and feeding a plugin hybrid. How do I make this cheaper or am I just doomed.

Another Sigenergy referral thread…

Apologies for creating another one of these - I tried some codes from previous threads but got various errors - the latest being “You have already participated in this activity”.

The message above makes it seem like a referral has already been applied but I don’t see it reflected anywhere in the app (notifications, rewards) or the website and got not confirmation error or email, so I’m very confused…

I’m still within the 7 day window and have eligible gear installed. Waiting to hear back from my installer. My system is online but hasn’t been signed off by the inspector yet if that makes a difference - I do remember some commissioning wording in the SIgen terms.

Anyone else had a similar experience?

On another note someone else mentioned a ChoiceCheapies referral system with random codes or having the mods in a thread for referral codes, I think that’d be a good idea.

Looking forward to another day of paying significantly less for power. ☀️⚡️

————————————————————————

Edit:

I reached out to my installer and he referred me to the Sigenergy helpline (+61 489 080 832). They couldn’t figure it out over the phone but got me to raise a support ticket for another team to look into. 🤞

————————————————————————

Edit 2:

I got this resolved by Sigenergy support today. Initially they thought I was trying to use my own referral code. 🙃 They had to send it off to their R&D team as tier 1 support couldn’t tell me if a code had been applied or not… Seems like one of the earlier codes got applied. 🎉

Thanks to all for your help.

Solar plans

Hey, we are getting solar in about 2 months, now we need to look at which provider we go with

Will be using approx 7200 kwh per year and estimated to generate about 10000 kwh per year

Will have a 10 KW battery and inverter

Who are people with and why

Hamilton based as well, thanks

Always interesting and useful looking at the predicted kwh collection, makes me chuckle how different my collection curve is to the predicted though
