question

Hello Lucian - Im from czech Republic - i have 1piece of EV charger with firmware V3.3/1.19-beta-14 connected to my system with 3pcs Quattros 10000 and 2 Fronius Symo 20.0-3 , i see EV charger at my vrm account and at remote console , but not possible to charge EV cars - Car NOT connected ( try some cars - same problem ) , Cerbo version 2.85 , can you help me with please? My email is : info@svabi.cz , thank you so much , Pampalasek_CZ

Thank you so much, at now i search for some EVs ... dont have at home.. i write answer to your email when i check it

Please keep me posted!

Hi Lucian , at now i test with Enyaq - car is detected - next step done :D , but not start charge because Low SOC Limit , at my FV have full Batteries at 100% , but charger

yes , its part of huge Victron system, in Charger web browser i have ip Cerbo gx by discover function and saved , at cerbo i have this fail 279466496_589164349469272_3336459484180363284_n.jpg

you have from yesterday - name Pampalasek

Awesome NEWS - Lucian GOT IT! First EV Victron Charger work perfectly at Czech Republic - it is first test piece - for now i wait for Enyaq when come with lowest SOC because when i tested have 98 SOC - i took some photos and posted here , very thanks him

First review: after some issues with getting updated to the right EV firmware version in combination with the Cerbo FW version I got it up&running perfectly! Thanks for your help Lucian! Next steps will be fiddling with the rest of the system in conjunction with the auto-charge option.

Will it possible to tell EV-Charger to charge from the grid and not from the battery if I have grid connected ESS system with Gerbo GX?
This would be helpfull when there is very low €/kwh price for few hours.

Hi, the charging station is the same as any other AC consumer, so it depends on how your ESS system is configured

Ahoj

Externě pracuji pro dodavatelskou firmu v ČR a testuji a konfiguruji vaše produkty pro její zákazníky. Mám několik otázek a postřehů ohledně vašeho produktu nabíječky EV.

Chtěl bych mít možnost nastavit minimální nabíjecí proud v automatickém režimu, aby se nabíječka nevypínala kvůli každému cloudu. Nekonečné opakování dělá tento režim nepoužitelným.

Máme zákazníky, kteří by uvítali jiný algoritmus v automatickém režimu, protože nesmějí dodávat do sítě přebytky.

Je možné spárovat nabíječku přes GX AP point? Nebo je nutný router s internetem?

Nemohu najít konfigurační kartu "Auto ON Grid".

Předem děkuji za odpověď.

Hello,

I am also from Czech Republic and planning to buy EV and also looking on Victron wallbox, because I have Victron PV system. My system is normally connected to grid (no off-grid) with 3 Multis, 3 MPPTs, Cerbo GX and 14.2 kWh in Pylontech batteries, system is configured as ESS.

My plan is connect EV charger on the AC-out-1 outputs (same as whole house installation) for possibility to charge the vehicle from PV modules (and also batteries) in case of grid outage.

How the charger in automatic mode works? Because during grid outage, there is no feed-in excess solar power. So will the wallbox in auto mode charge the vehicle or not? Is it possible to control charging and set parameters of EV charger using Node-RED flows in Cerbo GX?

Hi, yes, auto mode is not working off grid yet, but soon will.

Yes there are nodes for EVCS, so you can control it externally.

Switching from 1P to 3P requires both hardware and software changes. The current version's PCB is prepared for this, but there is only one contactor inside.

Hi @Lucian Popescu (Victron Energy Staff) and everyone, who already has Victron EV charger.

Now I am looking for used EV and I'm deciding between Nissan Leaf (1st generation with 30/28 kWh battery), Renault Zoe (Z.E.40 with 44.1/41 kWh battery) or maybe VW e-Golf (35.8/32 kWh battery). Nissan Leaf has only 1-phase AC charger with max. 6.6 kW charging power (and of course DC CHAdeMO), Renault Zoe has 3-phase AC charger with max. 22 kW charging power (in R90 version or 43 kW in Q90 version) and VW e-Golf has 2-phase AC charger with max. 7,2 kW charging power (and of course DC CCS).

If I assume max. 6 - 7 kW from PV panels, with Nissan Leaf I would have to add at least one 3k Multi in parallel to existing 3k Multi on one phase (for increase available power in one phase), with Renault Zoe or VW e-Golf basically nothing...

I see, there is min. charging current parameter in EV charging station. But I have some additional questions about function, which is not clearly described in documentation:

1. I assume, if I set EV charger to automatic mode, charging power is dynamically set by EV charger according to excess power from PV panels, right? What about situation, when excess power is not enough to complain with min. charging current/power limitation? Is charging automatically interrupted by EV charger?
2. Is charging power set according to the lowest excess power (actual lowest excess power in one of three phase)? For example Multi L1 feeds-in 2000 W, Multi L2 feeds-in 1600 W and Multi L3 feeds-in 1800 W to grid, so will EV charger set charging power to 4800 W (3x 1600 W)?
3. What about situation with VW e-Golf and 2-phase charging? Is it possible with the EV charger connected to 3-phase ESS? What about setting of charging power based on excess power (see question 3.) in case of 2-phase charging?
4. In the Czech Republic we have condition, that EV charger must have information about actual current/power of whole house installation from grid, and charging current/power must be set by EV charger to not exceed maximal reserved current/power (of whole installation) from grid, which is basically defined by main circuit breaker (for example 3x 25 A). EV charger can be connected via Wi-Fi with Cerbo GX, so it has access to all values measured by the system, especially current/power from grid. Is it possible to set maximal current/power limit consumed from grid and then EV charger can dynamically set charging current/power to not exceed this limit?
5. Do you plan some additional mode (or implementation in existing modes) with percentage parameter, which could define distribution of actual power from PV panels going to battery and going to EV charger (and home installation because I plan to connect EV charger to AC-out as whole home installation)? For example 60 % to battery and remaining 40 % to home installation with EV charger. Maybe of course some percentage (SOC) parameter, when EV charger can start charging the EV? For example when battery SOC reach 85 %, EV charger will automatically start and charge EV with 40 % of actual power from PV, battery will be charged with remaining 60 % of actual power.

Thank you very much for your answers!

Some demo logic, seems working in my setup. Grid meter, EVCS, weak grid just 7kw, weak solar big batteries. Quest is to not trip breaker. And car charge is priority. In the night there is some delaying to discharge flow of batteries, to last before people go to sleep.
