    V2L - vehicle to load adapter / cable

    RCD do not work without a N to PE bound. Normally the grid system provides this N-bound. V2L can and may not have a N to PE bound. Connecting V2L via an MTS or ATS creates safety issues. V2L can be used for V2H using a transformer, in island mode. Those who have solar panels and an all in one...

    V2L Test. 7kW output...

    Most car batteries are +- 350 - 400V DC. Hybrid solar transformers supporting high volt batteries are available. In that case the dc port of the EV can be used and the transformer to limit the current. I think making the EV dc port bi-directional should not be a big technical issue. How a dc...

    An AIO is an external ATS, automatic transfer switch? (I looked it up and it seems to be an All In One, normally having an internal bypass ( ATS); with or without usable dry contacts?) This info is also for connecting solar panels and it is important to warn for the possible problems if AIO are...

    V2L Test. 7kW output...

    What earthing system do you use? such off grid inverters have an internal bypass connecting the grid to the home load if batt volt is low. the AC in port can be used for grid or gen. This means it must be avoided the internal bypass to become active if connecting V2L to the AC in port to charge...

    V2L Test. 7kW output...

    if one has a hybrid solar inverter connected to batteries, most of them also have a GEN port. You just have to plug V2L output in the gen port and use it as it was an emergency generator. Using V2L one can not connect PE out to earth as this propably will stop de-charging. if only used for...

    Installing heated seats

    The advantage of having heated seats is consuming much less range for creating a comfortable environment in cold weather conditions, as is a heat pump. Both are standard equipment on all BYD Dolfin, for about the same price. The MG4 basic model has a bigger batt but this difference is not shown...

    V2L adapters

    Additional warning. Using V2l one is using a floating system. use double isolated tools only. It is dangerous to use a power block with multiple sockets; if two different people each use a tool at the same time connected to that V2L power block and one tool becomes faulty the second person using...

    I have solar pannels and use an all in one hybrid inverter with gen port. if connecting V2L to gen port it is able to recharge the home battery or supply power the the home load. I use an AC coupled hybrid DEYE inverter with back-up but one may use an all in one in series inverter creating an...

    V2L adapters

    I think this is an adapter for a BYD. BYD VtoL has PE/PP resistance of 1998 ohm.

    Those going for " proper dash" and value for money.have to go for Xpeng 9, Or in the C segment a BYD Dolfin. same price range as MG 4. Volvo does not come close , also not the very expensive EX 90 .

    It does, the EV must use resistance heat to warm the car and batteries if no heat pump. This drains the battery. The same EV with or without a heat ump, it makes a huge difference in range, Battery preheating for DC charging without a heatpump?

    Camping.

    As do most other cars pulling a caravan. 1/3 at least. This is not typical EV. I go from 6l/100km to 9L/ 100km pulling 1500kg, even 10l-12l in the mountains. An Ev loads his batteries coming down. It is about the same range most European EV lose in winter because they do not have a heatpump in...

    On an MG forum? Why? Being an expensive Chinese car the VOLVO EX 30 shows its European roots by NOT providing V2L functionality. It has towing capabilty for a caravan but only on a version 50% more expensive as the MG4. To become popular in EU an EV should have towing capability for min...

    Does anyone offer something like a V2L socket inside the vehicle?

    V2L is a floating system, it has no earthing. This means RCD will not work as they need a neutral connected to PE. The problem is plugs with multiple sockets are used. The system is suitable for double isolated devises as is a hedge trimmer but it is not suitable to plug in multiple devices...

    Does anyone offer something like a V2L socket inside the vehicle?

    A small inverter on the DC socket which is max 10A is max 120W. 2 x USB on a DC plug will provide about the same

    The same concerns may be made for connecting a generator. Most portable generators also are floating systems suitable only to connect one double isolated device in all safety. if such generator is connected to the home electrical installation of coarse a transfer switch must be used to avoid...

    V2L Test. 7kW output...

    V2L is a floating system, which means there is no protection. Only double isolated electrical devices may be connencted. Such devices have no earth wire. If you connect 4 devices and there is an isolation fault in one device this may have effect on all connected devices and its users. As...

    V2L Test. 7kW output...

    Earth wire coming from the MG? What is its normal purpose in a floating setup? This wire probably can be used to earth the MG internal inverter? Is this wire also providing an N bound if it is connected to earth? For this one should check if V2L N and PE are connected or not. I do not think this...

    V2L Test. 7kW output...

    In Belgium all home installations are TT systems ( Terra- Terra), which means the N is not bound to earth in the home distribution box and the N bound is made at the distribution transformer of the GRID. The home installation must have effective RCB and home earth may not be connected to N . I...

    In fact there is not a lot to avoid; It is about connecting one wire more or not.
