Bluetti AC240 Parallel Kit Review

I did this review as a video, so I hope you enjoy my introduction to the Fusion Kit, and as I put it to some serious use.

Hello
Thank you for the very informative video (including the log splitting section !).

Can you tell me if the parallel kit has fans or the cooling is completely passive ?
Can you use both the parallel kit and the power socket or DC socket on the A240 at the same time?

Many thanks to Henry for preparing the video on the AC240 parallel unit!
I believe this video can effectively help those who have questions about the P480A box. :nut_and_bolt:

You’re very welcome, I did rather enjoy making the log splitting section of the video. Regarding cooling, the parallel unit does not appear to have any electronics in it, and I believe that the synchronizing of the output is done by the AC240s. The connectors on the parallel kit includes communication and power connections. So there is no active cooling.

Honestly, I have not tried using an AC outlet on one of the AC240s while using the parallel kit. My expectation is that they will still work, but it would be interesting to see how the load balancing responds. I will test this, and the DC outputs too.

I found an opportunity to test the AC240s and parallel kit while also using the internal AC outlets. Basically, the USB and AC outlets on the individual units do work while in parallel mode, but how they responded to a load on a single AC240 while also powering a parallel load was quite interesting to see. @Snips1 I hope you find this helpful!

Thank you very much for this detailed test. I thought it was the batteries (DC) of the two Ac240 which were put in parallel, and in the parallel box there was an inverter… But you told me that there was no ventilation in the parallel box, this gave me doubts, and finally your test seems to confirm your analysis: the parallel box must allow the two inverters of the 2 Ac240s to synchronize to produce an AC signal in phase, then it is the AC outputs of the two inverters which are put in parallel (hence the 50/50 balancing even for a device connected to one of the Ac240s).
Thanks!
