Tracer and Triron compatibility. #47

Closed jimlynnjulian closed 2 years ago

jimlynnjulian commented 2 years ago

Just found a problem I was having. The existing driver works with Epever Triron4210N. The Triron is a plugin replacement for the Tracer3210A. UPDATE: I'm getting skips or partial reads in readings before the sun is up. Skips have indicated a too fast data rate , in the past. Checking into the issue. Currently suspect an update to PHP 7.4.

An extended description of the problem: The software reads and stores data from the solar panel array from 6AM to 6PM, daily. Throughout the year, the sun rises and sets at different times. Currently, the sun rises and sets earlier. This means the data is going to be collected before and after sunrise/sunset. It is at these times that data occasionally gets dropped/skipped. The latest PHP install may be at fault, but there are a couple of other possibiities. The Triron seems slower than the Tracer. This may account for the skips. The battery voltage sometimes drops unusually low. This seems to correlate with the data losses. The proprietary program can be run during a low light period with low battery voltage and compared to the PHP data collected. This will eliminate the Triron or PHP as a source of error.
