Used Xantrex inverter potential problems

 There have been a couple of instances where the inverter may be failing or creating anomolies.

I'm gettinga new RPi4 and using an SD card to eliminate the existing RPi4+SSD as a source of problems.

A new inverter may be needed. The csv files are not recording as usual.


A long standing problem solved

 

For a long time, The graph display was not reflecting the change to Daylight Savings Tme.

The solution lay in editing the php.ini file to set the date.timezone to "America/New_York".

The setting in the EpD3Dy.php file was commented out.

The display is now correct when the spring/autumn changes occurs.

However, the graphing now ends at 7PM instead of 6PM. A minor edit will correct that error.

Spring forward-Fall back
