And if you're interested, using that example, I have confirmed 5798 and 5799 to be INV1 temp and INV2 temperature in Celcius. 5800 appears to be temperatue also, but I don't know of what.. 1200 is actually 120.0 (assume volts) followed by 6 (assumed amps). This area of the registers will probably populate for you because they are related to GRID. 5793 may be power factor because 5792 is grid frequency. (it showed 5992 when i connected grid). Anyway, I THINK these registers need to be converted to hex for use HA, at least thats what i've been doing so far.
