ECTIVE CSI 20 PRO 2000W/12V Gen. 2 Pure Sine Wave Inverter with Mains Priority Circuit and Charger

The CSI PRO Gen. 2 is an all-in-one inverter that not only converts your battery energy into clean 230 V AC power, but also recharges it directly when connected to shore power. The three-stage IUoU charger delivers 40 A charging current and reliably and gently supports wet, AGM, gel, and lithium batteries. An integrated RCD/MCB ensures safety, while the mains and battery priority circuit guarantees a seamless, uninterrupted power supply.

The new Gen. 2 has been specially optimized for mobile use: The 45 mm shorter housing saves valuable space and facilitates installation in cramped technical compartments or under seats in campers. At the same time, new WAGO spring terminals ensure faster and more convenient AC wiring. The wake-up button can even reactivate lithium batteries with locked BMS. Temperature- and load-controlled ARCTIC brand fans with optimized cooling ensure pleasantly quiet operation.

The CSI PRO Gen. 2 is more than an inverter – it is a complete energy center. Thanks to the integrated battery charger, you save yourself an additional device, and with the selectable charging characteristics, the inverter adapts perfectly to your battery technology. Connect, charge, get started. With the second generation, we have consistently further developed the CSI PRO series based on practical feedback. The result: more comfort during installation, less space required, and the usual reliable ECTIVE performance.

Thanks to the combination of strong performance, integrated charging function, and maximum safety, the CSI PRO Gen. 2 inverters are among the most versatile solutions for mobile and self-sufficient power supply.
