# This script assumes you already have the mpp-solar python program running correctly and node_exporter, Prometheus and Grafana working.
# See my other documents for information on that.
# All this simple script does is convert the output for mpp-solar into a .prom file in the /ramdisk folder, so node_-exporter can read it and load into
# the Prometheus database. You can then graph the values in real--time with Grafana.
# mpp-solar parsing script for 2 x 3048 MPP all--in--one devices connected for split phase.
