Solar PV-4 is (4) WiFi connected DC Contactors
and 8 channel remote VOLTAGE MONITOR

Intended to be installed aside a PV Collector box.
Disconnecting individual PV strings allows for
voltage measurment on individual strings.
Accomplished by an 8 channel MCP3208 A/D converter
Onboard voltage divider provides high voltage accuracy.
Designed for Raspberry Pi 40 pin GPIO (RasPi 2, 3+).
Powered by +7.5 to 32vdc and provides all RasPi voltages.
