The Fox ESS L Series EV Charger now offers a direct connection to the H1-G2 hybrid inverter (K Series coming soon) offering system integration and smart control via the Fox Cloud app.
This is achieved via a direct cable connection from the inverter comms plug to the EV charger:

Please ensure you inverter is on the latest firmware and the EV charger firmware is 1.04 or higher.
