• User-friendly LCD setting and intuitive LED design The MAX III includes 12 important LCD settings with indicators on the front panel that lights up to display the current parameter settings. • Easy access cable design with sliding door The MAX III is designed with a sliding door on the LCD panel to facilitate installation. The installer can simply slide the control panel up and lock it with the holder to easily access cable wirings. • Dual inputs and Dual outputs for smart energy management The MAX III is designed to allow two independent AC power sources that would switch automatically to prevent power interruption. It is also equipped with dual outputs to allow output power to be arranged as desired. • Grid support and built-in CT sensor The MAX III has the grid-support function that allows large output power without changing the utility infrastructure and a built-in CT sensor that meets self-consumption application. • Built-in DC, AC breaker, PV DC switch MAX III contains a built-in DC breaker, AC breaker and PV DC switch to provide safety and reliability. • New wall mount bracket design The MAX III has a new wall mount bracket, which eliminates the need for installers to carry a heavy measurement machine. Installers simply need to install the new wall mount bracket and the machine is placed directly on it to complete installation. • Upgrade maximum PV power to 12000W The whole series is upgraded with 12000W PV power. • Parallel operation with 6 units For increased power and capacity, the MAX III allows parallel operation to up to 6 units by connecting additional inverters and batteries. This supports the wider applications of households and small businesses. • User Selectable Hybrid or Off-Grid mode inverter operation
