Conversol MAX-III 11kW – Advanced 3rd Generation Off-Grid Solar Inverter

Welcome to the future of energy independence with the Conversol MAX-III 11kW – the most advanced version of our solar off-grid inverter series. Launched in 2025, this 3rd generation system combines powerful performance with outstanding usability. Designed for single-phase installations (48V/230VAC), it delivers a robust 11kW of pure sine wave output and supports hybrid operation with both solar and grid power sources.

Unlike older inverter models, the MAX-III makes setup and daily use remarkably easy. A front-facing display highlights the 12 most essential settings, with LED indicators and clear labels – no need to scroll through endless menus or remember coded parameters. Just touch, read, and adjust.

We've also introduced a sliding cover system for rapid access to all power and communication terminals. Simply unlock the sides, lift the cover, and you’re in – no tools required.

With dual AC output and dual input terminals, built-in CT sensor, AC/DC breakers, PV isolator, and parallel support for up to six units, this inverter is ready for both small and large energy systems. Whether you're powering a home or a remote site, the MAX-III offers flexibility, power, and peace of mind – backed by a 2-year limited warranty.
