First, I would like to say that I’m very happy with the AC200max. It’s a nice all-in-one battery backup system for dummies like me. That said, I do wish it had some of these bells 'n whistles:
One step-connect - There is no need for 4 different screens just to connect!
Auto-connect to most recently viewed battery (especially if only one in list)
Reporting module with logging at 1 second interval for these data-points:
Charging input(s): PV, Grid
Outputs: DC and AC
(probably more – please chime in if you have ideas)
CSV (or xlsx) export of above reporting data.
USB to wi-fi connector (allows wi-fi connect even though it’s not built in to the system) This could then be used to export data to a reporting server anywhere in the world!
Auto-on for external batteries (e.g., B300) when PV starts-up the AC200max.
Configurable Grid-power schedule. For example, only charge the battery from grid from 12am to 6 am (yes, I live in a Time-of-use zone). Just FYI: I tried a timer, but it didn’t wake the battery when Grid-power turned on.
Configurable shut-down schedule. For example, shut down 10 minutes after no PV charge. Shut down after x-minutes of non-use. In either case, PV input should wake up system again (as it does now).
I realize most of this is unlikely to be updated for my current AC200max, but these would be huge improvements for future products.
