PointGuard bi-directional system

[tearitupsports]

About to be new to market, but this company has a bi-directional system capable of working with F150 lightning.
I don't have a lot of details yet, but new video came out today.

I hope this means that there will be multiple options soon for bidirectional charging.

Or you can buy, today, Ford’s Home Integration System, that’s been around for over 2 years.

Video is a little misleading. Don’t you need more than some small charger to get power to the grid?

 

[leejimerson]

Yes, you need the $4-5K Ford (Sunrun/Siemens/Delta) Home Integration System, plus installation that will run $5-10K, and a couple hundred hours + of your time trying to get it to work, and keep working. Definitely bleeding edge technology at this point, which is great, if you enjoy it

Video is a useless paid promotion with ZERO information. Hey someone wants to do a thing and it's coming soon!

As of now, there are no other systems compatible with the lightning for bidirectional. Perhaps one day there will be. But I expect nothing but a fluster cluck of yet more proprietary equipment that may or may not work.

You must be new here? It's been around for two years.. and hasn't functioned properly or reliably yet. The system is garbage. Neither manufacturer involved (Ford & Siemens) are doing anything to fix it.

I already have a working Home Integration System. The PointGuard system is vastly superior although I haven’t seen the price yet.

Did you actually watch all the video? They have this working with the Lightning (shown in video) and Mercedes. They also mention but don’t show a Rivian. The system charges and discharges entirely through DC. There is no AC charging with the V2x module.
release date is April for the module. System is available now.

And many people don't yet have it working. I believe some started a class action lawsuit.

Haven't watched, but I did search it. $5k cost for the equipment and have the option to add multiple batteries to the system. Most of the time I charge it's at night, so does that mean this unit has to convert grid AC to DC in order charge?

I'm still waiting to see what Emporia comes out with. Glad to see there's a standard now. Now we just need the automakers to play along.

This unit can charge the truck from AC grid (up to about 11kW), from the home batteries (up to like 8kW) or from excess solar. It can do all 3 at once for up to 25kW since it is a DC charger.
I don’t see a use case really for charging from home battery though unless it is an emergency so effectively this is a 11.4kW charger at night.

It is not a DC charger. Its a pass-thru device that is using the existing solar and or batteries to match the DC charging voltage of the EV.

This whole thread is misleading and based on a product not commercially offered.

While we're at it... Enphase, Solaredge, Emporia, Wallbox, Highbury, Fermata, and others all make this product as well.

How so? Link to where I can buy it? Cause its not on Pointguards site. At their distributor. Or at their parent company https://www.sigenergy.com/en that they are just a sub-brand of.

While most are indeed vaporware this is being released in April for sale.
And yes it’s on the parent site

Not available in North America. Also only a DC charger if you have DC things that work with it...

This is just a different Ford/Delta solution.... thats not available.

Sigen EV DC Charging Module

A genuinely future - proof product. It supports 25kW bi - directional charging, establishing itself as the central connection point between EVs and homes. Leveraging the advanced DC - coupled architecture, it allows EVs to be directly charged with solar - generated green electricity, thus facilitating eco - friendly mobility.

*V2X functionality is limited by the EV's capabilities. Once the relevant standards are published, V2X feature can be upgraded through the OTA. For the official support of vehicle models and support timelines, please refer to future announcement made on the official website.

The DC charger does not seem much different from other previously announced bi-directional chargers (e.g. dcBel, Wallbox, etc.) in that the V2X function is still waiting for relevant standards to be implemented by EV makers. The short video snippet does seem to show power discharging but not how much so it's doubt they can do high power (>>5kW) discharging (at least on existing American EV's). There are already several what I call pseudo-V2X products taking advantage of existing "bugs" in DC charging implementation on various EV's that allow limited discharging (not always reliable). So, it's possible the PointGuard/Sigenergy product is also using the same mechanism. It seems plausible given the V2X caveat included in their marketing content. So, it looks more like a gimmick to help sell their batteries and chargers.

Here is an example of the pseudo-V2X products that have been available for sale for a while now:
https://elejoy.com/products/elejoy-...8cUbQPv0cGfwPH-2Cg1xe6Qj1eDIzThcxAwtZerxtlYBH. One key problem with these devices is that EV makers can easily make them useless with firmware updates that fix the "bugs".
