xConversol MAX-III 11kW Hybrid Off-Grid Inverter – Third Generation
The Conversol MAX-III 11kW is our most advanced third-generation hybrid inverter. Designed for off-grid and grid-support installations, it provides 230V pure sine wave output and supports up to 12000W of solar PV input. This high-performance system gives you flexible energy management with dual AC input and output, plus built-in breakers for fast, clean installations.
Effortless Operation
Forget complicated menus and hard-to-read codes. The MAX-III uses a simplified control interface with just 12 clear settings displayed on one screen. LED indicators provide instant system feedback—even before you press a button.
Faster, Safer Installation
With its sliding front cover, accessing terminals is easy—no tools needed. The clean layout and clearly labelled connections speed up both installation and maintenance. A reinforced wall bracket keeps the unit secure in any location.
Smart Energy Management
Dual AC input and output ports let you split loads or manage backup systems. The built-in CT sensor enables the inverter to prioritise solar self-consumption before using or exporting power to the grid. It also supports high-output applications without needing to upgrade the utility connection.
Built-In Safety Features
The Conversol MAX-III 11kW includes pre-installed AC and DC breakers and a PV disconnect switch for safer and tidier installs. It’s a plug-and-play solution designed to reduce inspection issues and simplify compliance.
