question

warranty is something the EV owners should think about, nothing to do with the technical possibility. The Spanish Wallbox building a factory in Texas and probably this will be an "industry standard" in US and around the world. The EVs which already have officially enabled V2L like the BYD has no warranty issues at all. So, here on Victron side we just need integration into Cerbo GX. I have read some people managed to connect the Wallbox to Cerbo GX via Modbus TCP but cerbo GX does not show the Wallbox on the display yet. Please look into this as Wallbox is the best on the market when it comes bidirectional charging.

your statement is completely wrong. Any electric car which has V2L function can use Wallbox Quasar 2 and never ever had any warranty issues. Are you serious stating this? You are saying using the top EV charger brand Wallbox can void warranty!!! Please send your statement directly to Wallbox company so they can respond the false accusations

Wallbox and KIA, just one example https://wallbox.com/en_us/newsroom/wallbox-and-kia-america-join-forces-on-bidirectional-ev-charging-.html

Knowing the different solar inverter vendors' extreme unwillingness to integrate different vendors into their ecosystems one needs an alternative solution.

The problem:

Many Solar PV systems are using different vendors, for example combination of Victron, SolarEdge, Fronius, SMA, Huawei, etc, etc and also different BMS solutions and different energy/power meters and now there many different EV charger solutions too.

Most vendors are ONLY focusing on their own product, however most of the time that one is not the best, for example Victron does not even have a working bidirectional EV charger even if they have good AC/DC inverters.

Now what the solutions on such mess?

One needs a software platform that is able to handle different vendors and their different protocols into one ecosystem.

Not hard to guess no vendors willing to invest their R&D on such however the open source community already realized this and came up with a solution.

Actually it is very simiar to Cerbo gx / Venus OS but here they address the issues that never been addressed by Victron;

- multi vendor support (inverters, energy meters, EV chargers)

- much needed functions like EV charging ONLY from solar energy !!!!

- LOT MORE MODERN solution than any other commercial ones, no need to lead new wires around the house for energy measurement for different devices, EVCC talks pretty much all protocols, for example modbus TCP over LAN or WIFI

- open source, written by passionate and highly skilled software engineers

- home automation capable, Home Assistant Integration

As you write above "open source, written by passionate and highly skilled software engineers" is highly contradictory : someone will have to pay, and as the saying goes : if it's free, you're the product.

clearly @jeanmarie you have absolutely now idea what open source software means, even if Victron has open source software. .. The main benefit of using Victron it gives some freedom of configuration. ..
