    what is the minimum kw power the seal accepts when charging only from solar?

     

    My charger is 7kW so you would need 10kW of PV. If you used the 3.5kW “Granny Charger” /mobile charger then 5kW would be ok.

     

    As I have batteries with my solar system I can “borrow” power from my home batteries and pay it back later in the day. The picture on the left before my latest upgrade shows that happening.

    can the ABB wallbox regulate so that only solar power is used for charging, without drawing anything

      from the home's energy storage system or from PEA?  

     

    No it can’t.

     

    I contact Myenergi in the UK about their Zappi charger that does this, only to discover that it simply monitors power being exported to the grid and sends the exact same amount into the charger - no use for me being off-grid.

    given the varying solar surplus, are these fluctuations problematic for charging the seal’s FLP?  

     

    It’s not a completely passive thing as you have to monitor the state of charge of the house batteries, but I have being doing it for 4 years now without any drama. The car is getting a steady 6.8kW from either my PV or home batteries so no problem there.

    it would be great if there were a wall charger that could automatically regulate charging based on solar surplus and also have

    a V2H function! if i remember correctly, some innovative products, like intelligent wall chargers, are already on the market,

    but they haven’t made it to thailand yet...

     

    I would be interested in this dc-to-dc solar-powered ev charger

     

     

     

     

    Currently V2H is complicated as most people don’t want to power their whole house in an emergency but just some circuits, making the installation much more expensive and complicated than my V2L setup.

  2. I am powering my house every night from my BYD Seal. I use about 10% of the battery to do it and I need to be able to charge from Solar for an hour the next day to cover that, plus whatever driving I’ve been doing.

     

    It means that my house LFP batteries are never dropping below 50% and so reduces their cycles from about once a day to once every 2 days. My Seal cycles are about every 5 days.

     

    We have had 2 weeks of very heavy rain, but the odd breaks in the rain have been enough to keep my house and 2 EVs plus an electric bike sufficiently charged and me off-grid.

     

    It’s not unusual for me to have 3 chargers going at the same time

     

    I could add a few kWh to the Seal when my local chargers are on off-peak rate but so far I haven’t had to.

     

    One day of no rain and all vehicles and the house back to 100%

    that would be very disappointing, only 3.6 kw from the free 11 kw ABB wallbox.

    can any other byd seal owners confirm this poor performance?

    i've never heard of this issue before!


    I’m getting 6.8kW, but I assumed they gave me a single phase 7kW ABB wallbox

    I have a BYD Dolphin but my only debit card is a Bangkok Bank Mastercard which Rever doesn't allow to be registered. Has anyone found a way round this problem? BB just charged me 599 baht annual fee so I don't really want to pay for another card.. 

     

    Now Rever are offering free charging we would like to take a road trip or two. 

     

    I have a Planet SCB card which is a prepaid card and seems to be recognised as a Credit Card by some EV chargers when my debit card wasn’t accepted.

    There is also un update coming for the Byd Seal but it will take some time I believe to arrive in Thailand. 

     

    Saw a video on the updated Seal by the Electric Viking 

     

    The main thing seemed to be full 800 Volt architecture that means faster charging. I not bothered about an updated interior that he was raving about. 

     

    To be honest I really think 150kW is fast enough. There are not that many chargers in Thailand that are much faster. 

     

    Bjørn Nyland tested the Seal and said that it had a very flat charging curve, holding 150kW right up to 80% SOC, where as Teslas have a headline rate of 250kW, but only holding that until about 30-40% SOC then dropping down to 100kW
