Description
xAxpert MAX III 12KW Hybrid & Off-Grid Solar Inverter
The Conversol MAX-III 12kW is a third-gen 48V single-phase hybrid inverter made for real-world off-grid or grid-support systems. It delivers 230V pure sine wave output and supports up to 18kW of solar input. You can connect solar and grid sources, with the inverter managing energy use intelligently based on system conditions.
Speed Meets Simplicity
You won't find any deep menu trees or cryptic codes on this hybrid inverter. Instead, operate it with 12 powerful settings displayed across one screen. LED indicators give you a status check at a glance, before you even touch a button.
Wiring is faster, too, thanks to the sliding front cover. Simply lift it to access all the terminals. No tools required. The layout is clean and clearly labelled, which speeds up both installs and maintenance.
What's more, dual AC input and dual output ports give flexibility for backup loads or split circuits. Built-in CT sensor means the inverter can prioritise self-use before drawing or sending power to the grid. It also features a grid-support function, enabling high output without utility upgrades.
The Conversol MAX-III 12kW Hybrid Inverter comes with integrated AC and DC breakers, as well as a PV disconnect and robust wall bracket. The result is a cleaner install and fewer inspection issues.
Finally, you can parallel up to six units for more capacity in the future. A two-year warranty gives you peace of mind.
So, if you're after a dependable, installer-friendly hybrid inverter, this is it
