Using a 220-240V system can indeed be more efficient than a 120V system in several ways, even when stepping down the voltage. Here are some key points to summarize and explain why this might be the case: Reduced Current Draw: For the same power (wattage), the current draw at 220-240V is approximately half of what it would be at 120V. This reduction in current means that there is less power loss due to the resistance in the wires (since power loss is proportional to the square of the current, For example, for 2,000 watts: At 120V, the current is 16.67A. At 240V, the current is 8.33A. Efficiency of Power Conversion: Power converters (such as inverters and transformers) typically have efficiencies that can be higher when dealing with higher voltages and lower currents. This is due to reduced I²R losses and often better performance characteristics of the components used. Stepping down from 240V to 120V in your case helps to maintain these efficiencies and results in a well-balanced power distribution. System Design and Heat Management: Lower currents result in less heat generation in wires and connections. This not only improves safety by reducing the risk of overheating but also helps in maintaining the longevity of the system components. Warm but not hot wires indicate that the system is operating within safe thermal limits. Load Balancing and Distribution: By using a 220-240V inverter, you are able to distribute the power load more effectively, which can be especially beneficial when dealing with high power requirements like 2,000 watts. The pass-through and charging mechanisms of the VEVOR hybrid system are likely optimized for these voltages, ensuring efficient handling of power. International Standards and Compatibility: Many international systems are designed for 220-240V operation, which might mean better availability of components and potentially better design optimizations. In summary, your decision to use a 220-240V system, even when stepping down to 120V, has likely resulted in a more efficient and balanced system. The reduced current draw, improved efficiency of power conversion, better heat management, and effective load distribution all contribute to the overall performance and reliability of your solar backup system. In short, using a 220 - 240 volt system is more efficent. Then th traditional 120 system.
This is the perfect solution after hurricane “ Ian “ or any other SHTF situation on this great channel for a DIY off grid build . People should never be left without power if they would only have the ability 🤔to come up with a great system to keep the lights on . 🔋🔋☀️🔌😉
Just come accoss your video I'm using the same unit. Its good to see a positive video on the unit. I'm in the UK its a great Inverter but its very noisy when both fans run I found.
It has been a while my friend, you know me, I think out side the box, I found an answer to the challange. Of 240 to 120 conversion. VEVOR 5000W Voltage Converter Transformer. The VEVOR 5000W Voltage Converter Transformer has a 220/240 switch on the back of this thing, which allows it to take in the 240 and step it down to 120 or 110. I have ordered both units and plan on setting the entire system up. I'll have to cut the plug at the end and following the wire coding ND diagram to make sure that the voltage in is matching with the voltage out. Seeing how I do not think this is a split phase unit. I will be using the VEVOR 5000W Voltage Converter Transformer, now while the VEVOR 5000W Voltage Converter Transformer is rate fo 5 KW, I know I can not go over the main unit's power specks. On the plus side this can make for a nice clan install. For stepping down the power. There are additional out let's that allow for one to use the 220 Volts for appliances that call for that. I am doing this, because I do not think a traditional breaker panel even ground to neutral bonded wound work for this. Just by looking at how that thing is put together. Who knows I may just may be getting the US version, but hey I'll take what I can get... International.. Works lol.. so.. Tell me what you think? I lso read the torque for the screws.. Those are some interesting torgue values. I will need a second VEVOR 5000W Voltage Converter Transformer to step up the power for the plugging in the Inverter. Yes, I am finally yielding to the 24 volt ideal... It makes a great deal of sense and well wiring and costs are cheaper. At any rate, have an awesome day. Hmmon the second though I could set up a 200 watt 24 volt power supply to the solar in lol. But, I much rather wire the thing up in an appropriate way. Or, I just by 240 volt toaster oven and bread machine lol... And other 240 volt appliances... Which would cost a lot of money in the long run..
@@jwsolarusa yes but we dont know what that is for this VW batteryes are. We have get builded 2 case of batteryes. And the builder told us to stop topp at 25.5 volt. But cant get hybrid inverter in user to sharge ore nothing. And there is 40 menu in user. And we are 2 friends whit 2 case we not can use
Oh and my e-bike battery surges to 1kw when it is plugged in to the solar in.. To which I did an immediate shut down, now while you have the International version you can step down the po using a step down trans former which have built in breakers. 220 Volt inverters are more efficient.

When u goes from agm to lithium golf batteryes. What all 40 in user shud stay at ???
Cos have to go to use user for lithium in this one
Yes use the user to setup your battery manufacturer specifications
@@jwsolarusa yes but we dont know what that is for this VW batteryes are.
We have get builded 2 case of batteryes.
And the builder told us to stop topp at 25.5 volt.
But cant get hybrid inverter in user to sharge ore nothing.
And there is 40 menu in user.
And we are 2 friends whit 2 case we not can use
Yes video👍 ☀⚡🔌💡🔋
Thanks
