I have watched the videos of the Anker Solix X1. Looks great until .........
You realize that it is completely proprietary. If Anker fails, you are done for, no warranty, no repair, no service. Another issue is that Anker spent so much time making this unit only 5.5 inches in depth, that the battery stacks are very limited in the videos so far. I could be wrong, but it looks like every stack I have seen has an inverter on the top. And if you stack more than say 4 batteries and the inverter, then the inverter is too high to reach standing on the ground.
Next, each inverter is only 6.6 kW. That's low. Many homes will need 3-4 inverters to power the home and HVAC. That's a lot of wall width. If you have 4 inverters, what do you do, put 2 batteries on each for 40 kW . Do they share all the batteries so one inverter is the master? And what about the battery voltage, it means for larger cabling.
It's got a lot of great features from the technology point of view, but the packaging is very limited and it seem intended for smaller homes and easy installation rather than larger homes that need a more robust inverter and 60-100 kW of back up.
Lastly, remember the Sony beta VCR. They were proprietary too and the best, but other companies drove it to extinction with VHS. If Anker is soo good, license your technology, put it in different package forms to reach more homes and businesses.
For now, I think the best solution out there is Sol-Ark due to the range of inverter capacities and the wide range of battery compatibility with battery closed loop functionality. It simply meets more needs, indoor and outdoor while providing future safeguards if the inverter fails or the batteries fail.
Where Sol-Ark needs to head is in the use of high voltage battery stacks and an outdoor convection cooling design.
