solar energy monitoring with an ESP8266 with 2 times a soladin 600 Mastervolt inverter.

Solar hot water panels. Controlled with ESP8266 Wemos D1 mini. Pump turns on to pump water when its hotter outside.

Displaying data output from a MPPT PCM6048 solar charger. The solar charger handles 6 X 195 Watt solar panels. Battery bank is 24 Volt. Capacity is 400 Ampere Hours at 24 Volt

Display power output from solar powered battery bank. Producing power for 7 stage grid inverter. Output controlled by household power consumption masurement. (Current transformer)

Single 250w solar panel connected to 350w grid tie inverter. Measuring done with Arduino Mega 2650 and Ethernet Shield to directly connect to ThingSpeak. sampled 100 times per second and then averaged for per second monitoring but 30 sec update to here.

Electrical & onsite parameters for solar panel located in COEP.
