Use an OpenWRT router or similar to send the start signal via WiFi. You can use Wireshark to reverse engineer the protocol. Use a comparator or ADC to check the battery bank voltage, low pass filtered with at least 10 seconds time constant so a voltage sag due to inrush doesn't trigger it.
To my surprise, shortly after Naomi Wu gave me a bit of fame for making good use of solar power, Allie Moore got really jealous of her...
