Growatt 11.4kW Grid-Tie Inverter (V3) | MIN 11400TL-XH-US

I liked the fast ship, the fair price. I don't like that the technical support is weak. I called at least 3 times and so far nobody has returned my call/message. update - portable sun delivered, so 5 stars, it's Growatt's US customer support, they will answer but i felt as if they didn't know how to provide quality support and provide detail or attempt to call back if the call is disrupted or disconnected.
