Pytes JS3PL12K 12 kW Hybrid Inverter 3-Phase

The JS3PL12K Hybrid Inverter from the JS series by PYTES offers a powerful solution in the segment of three-phase hybrid inverters. With a nominal power of 12 kW and comprehensive protection features, it is optimal for demanding PV systems with storage in residential and commercial applications. Intelligent energy management enables efficient distribution between solar generator, battery, and grid.

The combination of solar, battery, and grid operation allows for maximum self-consumption optimization while providing backup power capability. Thanks to the IP66 protection class, the inverter can be reliably used even under adverse environmental conditions. An OEM warranty of at least 5 years provides planning security for operators.

Introduction to Features

With its high connection power of up to 19.2 kW PV input, the JS3PL12K reliably delivers energy surplus with optimal panel utilization. The two independent MPPT trackers allow for maximum yield with different string configurations or orientations.

The modern cooling strategy (intelligent fan) ensures stable operational security even under hot conditions (< 65 dB, IP66). In backup mode, the inverter delivers up to twice the nominal power for a short time during a grid failure – ideal for ensuring critical loads.

Advantages at a Glance

• High self-consumption through battery integration and MPPT control
• Backup capability during grid failure (Backup Switch Time < 10 ms)
• Scalable: parallel operation of multiple units possible (up to 90 kW for microgrid formation)
• Robust with absolutely weatherproof protection class IP66
• Easy installation & configuration via app or LCD menu
• Wide battery compatibility (Li-Ion, Lead-Acid), BMS connection (CAN/RS485)

Scope of Delivery

• 1 × JS3PL12K Hybrid Inverter
• DC and AC connection cable set
• Mounting bracket & fastening material
• Operating manual (German/English)
