Is pure sine wave required for AC180

Does AC180 require pure sine wave? I think with the grid enhance mode, I should be able to use a modified sine inverter in my car? @BLUETTI_CARE

Not sure what you mean? A pure sine inverter would always be preferred. Its a higher quality of AC output signal.

You will need a pure sine wave inverter for the AC180 if your intention is to charge the unit through the ac input port by using a 120 volt inverter source.

I know it is preferred and I know it is better. BUT is it a must? That is my question.

That is my intention but I am getting contradiction information and I want official answer from @BLUETTI_CARE

There are few review videos I found online that specifically say that AC180 is the first one that does not require it. For grid enhancement, mode manual says "This mode ensures that the AC180 has a stable and continuous AC input, as it allows AC180 to adapt to voltage fluctuations and waveform distortion of an AC source."

So while prior products required it, it is my understanding that AC180 has a feature to deal with it.

Unfortunately I am having an issue finding a pure sine inverter that works with my Tesla when I tap into its 12V system. It is not a money thing… I just bought a renogy inverter and it does not work with my car. However, I found a motomaster 1500w inverter (not pure sine wave) that works just fine.

So your talking about charging the unit? Thats where I misunderstood. It’s true that some brick chargers don’t like noisy AC inputs. You might be able to get by with it but you would just have to try it. From your description it sounds like you could use a modified sine inverter but in the end you will just have to try it.

Yes, charging the unit.

It was suggested to consider dc to dc step up to 48V for most efficient charging option from a vehicle but Tesla uses 360W of power to stay awake. So it would be more efficient to use turbo mode to charge in 1 hour with ac inverter vs taking 3 hours at 450W using the dc to dc converter.

This would not be the primary way of charging but just as a top up method when solar can not keep up with demand.

I would look for a 2500 to 3000 watt pure sine wave inverter of which there are many to choose from on amazon. Bad power from a non sine wave inverter is not a recipe for long term durability even if your AC180 will charge from it. If money is not the issue, I am having trouble why you wouldn’t want a unit that produced good clean power when they are so easy to find. If you are not looking at a max rate charging, I would recommend the victron 1200 watt inverter which comes in 12,24, 36 or 48 volt inputs. Having double the capacity inverter for what your long term load is so as not to overheat or shorten the life of the inverter. Few things in life will last if used at maximum capacity for long periods of time which is what charging is.

I just got a 2,000 watt Renogy pure sine inverter and it causes the vehicle to throw a bunch of codes and makes it not drivable. These inverters are designed for connecting to batteries, not DC power supply (which is the case in a Tesla). Tesla sees in rush current to large capacitors inside the inverter as a short circuit, it blows efuses and car protects itself. I even built a soft loading circuit, using a relay and some resistors, but still no luck. So to answer your question, I tried pure sign inverters, but they do not work for Tesla vehicles. The only inverter I found so far is a 1500 W modified sine wave inverter that seems to work fine with the vehicle itself.

I would think a dc load is a dc load whether it is a pure sine wave inverter or not. More than likely it was the amount of amp load that was the issue and the smaller 1500 watt unit drew less power.

@ataman First of all, please make sure that the output power of the inverter is greater than the charging power of AC180. Also, a pure sine wave is best. If it’s not a pure sine wave, you’ll need to charge it with an adapter.
