Używa ktoś może ładowarki dwukierunkowej #Sigen #Sigenergy 25kW #EV DC? Tej w ofercie #Pstryk? Interesują mnie praktyczne doświadczenia z używania jej w trybie, no właśnie, dwukierunkowym. Strona producenta ma taką tabelkę z testowanymi samochodami, ale brak konkretnej specyfikacji. #elektromobilność

@skolima That's cool. I know they're active in Australia already - it's an elegant solution to use one hybrid inverter for the home battery as well as the EV (+ ideally also the solar)

@burger_jaap The house in question has an existing SolarEdge PV installation (13 kWp installed), so the setup becomes somewhat more complicated. But it looks like this is the first (and only, so far?) bidirectional charger that is not car-manufacturer specific.

@skolima Wonder what the price of a system is? It's 'ask for a quote' on the website, it seems... https://pstryk.pl/kup-magazyn-energii

Also offered in Europe is the ambibox V2G charger, which supports more or less the same vehicles, I guess - and has official support for the VW Group EVs (VW, Ford, Skoda etc.)

@burger_jaap I got a 14k EUR quote for a 27 kWh battery, DC charger 25kW and all the other related hardware required. I need to confirm if this includes installation too (but the offer uses lower 8% VAT rate which suggests it does include installation). This should also be eligible for the new round of subsidies here in Poland, up to 4k EUR.

@skolima My supplier in the Netherlands (tibber) offers a 20 kWh system with basic installation for 7k EUR (at 0% VAT rate) - but that's not capable of island / off-grid mode, nor EV charging.

@burger_jaap Right, I'm aware that's per kWh one of the pricier options (though with a nice benefit of being able to add 9 kWh modules later without need for matching series / date of production), but for the full set of capabilities there's nothing I can find that would match.

And the island mode will come in handy - one, it's required for subsidies in Poland now, two, that's for a rural property which often gets grid outages after heavy winds.

@skolima It would also be my preference to have the island mode. And yes, adding the car would be even nicer.
