I was told by Signature Solar that the 200AH 24V batteries will have an LCD and will be able to communicate with any Growatt which is completely awesome if this is true. As of now there are no photos of this nor mention in any of Gylls paperwork. Also they say that the front panel will have a breaker like the 48V version. If all this comes to fruition, then it would be really hard to pass up for all the obvious reasons. I put my order in for 4 of the 24V with Signature despite the negativity. I expect to receive them in June / July timeframe. The new tech is pretty exciting and does somewhat come with taking a leap of faith with no specs or paperwork to review. My hats off to Will for making this venture time after time and then publicly sharing the results. Anyhoo getting closer to my 24KW mobile go anywhere / do anything machine!
