The EVTV Enphase Diversion Loads Manager is a standalone WiFi device that communicates directly with your ENPHASE ENVOY data gateway device via your home WiFi Router/network to obtain operational data on your Enphase solar power system.
It features FOUR switched MOSFET outputs that can drive four external relays at 12v and up to 3 amps each. In this way, you can switch on and off diversion loads such as water heaters, hot tubs, EV charging, etc. based on the output power of your Enphase solar arrray.
Additionally, it will also monitor our Tesla Model S Battery Monitor/Controller for similar data allowing outputs to be swtiched based on voltage, current, or SOC of your Tesla Model S battery module battery pack.
