How far from the microinverters can the ECU be placed? How far from the site's wireless router?

The ECU can communicate with the inverters via Zigbee up to 76 meters (250 ft) with direct sight and can utilize Wi-Fi (WLAN) to connect to the site owner’s wireless router up to 9 meters (30 ft) with direct sight, however this last point depends primarily on the site owner’s wireless router’s capability.
