F12.15 and F12.16 are used together to check the cumulative power-on time of the
inverter from delivery to the current moment (you only need to power on the inverter). The
cumulative power-on time is accurate to one minute and nearly 65,536 hours (about 7.5
years) at most.
If F12.15=50 and F12.16=33, it means that the current inverter has been powered on
for 2 days, 2 hours and 33 minutes.
