KACO blueplanet 3.7 NX1 M2 - Optimally Tuned to German Regulations

The KACO blueplanet 3.7 NX1 M2 is a transformerless single-phase string inverter with 3.68 kW rated power. This power class is optimally tuned to the German 70 percent feed-in regulation and enables maximum system sizes without additional control technology.

Perfect for the 70% Regulation

With 3.68 kW AC rated power, the KACO blueplanet 3.7 NX1 M2 allows PV generator power of 5.26 kWp while complying with the 70 percent regulation. The recommended maximum PV power of 5.52 kWp enables slight oversizing for higher yields even under suboptimal conditions.

Two Independent MPP Trackers

The blueplanet 3.7 NX1 M2 offers two MPP trackers with one string connection each and maximum 3,500 W per tracker. The MPP range of 165 to 480 V at rated power and operating range of 80 to 550 VDC provide flexibility in string design. Maximum open circuit voltage is 580 VDC.

97.5% Peak Efficiency

The KACO blueplanet 3.7 NX1 M2 achieves maximum efficiency of 97.5 percent and European weighted efficiency of 97 percent. The transformerless circuit topology contributes significantly to this high efficiency and minimizes thermal losses.

Featherlight at Only 11 kg

The low weight of only 11 kg makes the blueplanet 3.7 NX1 M2 a lightweight among string inverters. Installation is possible without tools, even in hard-to-reach places. IP65 protection rating allows outdoor installation without additional enclosure.

Easy WiFi Setup with App

Commissioning and monitoring of the KACO blueplanet 3.7 NX1 M2 is done via a user-friendly smartphone app. The integrated WiFi module enables wireless connection. Convection cooling operates silently below 25 dB(A).
