V2H status?

[fafrd]

thanks for the info.

any option that requires a connection to internet is a complete non starter, personally.

half the entire exercise is about resiliency. internet goes out more than power

appreciate the info, thanks!

My views are not that different, but I’d want to understand what functionality is maintained during an internet outage and what competing stand alone products offer as far as price and capability.

My goal is to control a V2H bidirectional charger and if the Emporia solution makes that easy-enough, that’s worth some compromise to me.

Will V2H still work if you have microinverters?

Micros should work just like any other GT inverter. I don't know the specs of the V2H equipment but hopefully it would have the ability to AC couple with existing GT systems.

Yes, a V2H inverter looks to your electrical system and the grid just like any other grid-tied inverter (string inverter or microinverter).

So for in-grid application (offset of liad consumption from EV energy), there should be no issue.

For backup capability (iff-grid through transfer switch once grid goes down), the answer is a bit more complex.

If the V2H inverter supports frequency-shift and the Microinverters also support frequency-shuft and are alto rerouted to the Critical Loads panel, the Microinverters should be able to function governed by the grid-forming function of the V2H inverter.

If either the Microinverters or the V2H inverter do not support frequency shift, the best you can hope for is that the Microinverters will function until the V2H inverter has charged the EV and then they will be shut down until the next morning.

I just discovered that Victron recently introduced a new EV Charger: https://www.victronenergy.com/accessories/ev-charging-station

It's a Smart Charger that can be configured to only charge the EV with excess solar energy and given Victron's reputation for effectively integrating their various products together, I suspect the smart capability is top-notch in an all-Victron system.

Now that the bidirectional charging standard has been published (finally!) I'm hoping Victron plans to add to this new product line by introducing a V2H-capabe bidirectional charger in 2024 or possibly even next year.

The prospect of a Victron Multiplus II 120x2 powered by a 48V or 24V House Battery integrated with a Victron SCC and now a Victron V2H-capable bidirectional charger is probably one of the most compelling multi-box solutions to self-consume while remaining tied to the grid that I can see on the ~2024 horizon...

If your EV can't do V2L (Tesla for example) and you need home power backup, plug this device to CCS port of your car and you will get 5kW AC.

The device work in off-grid mode, so always make sure to islanding your house via a transfer switch. See link below.
