Overview
The PowMr POW-SunSmart 12KPL3 is a 12,000W 48V solar hybrid inverter designed for three-phase pure sine wave output at 230/400Vac (350~415V). It supports dual MPPT PV inputs (max open-circuit voltage 800Vdc/800Vdc) and parallel operation up to 6 units.
Key Features
- Three-phase pure sine wave output: 230/400Vac three-phase; supports phase voltage adjustment at 200/208/220/230/240Vac; output frequency 50/60Hz.
- Dual MPPT solar charging: 2 MPPT, MPPT tracking efficiency 99.9%, max input current 22/22A, and max hybrid charging current 260A. Dual MPPT manages each 9000W input.
- Battery compatibility: 48Vdc battery system supporting Li-ion, Lead-Acid, and User Defined battery types; includes dual activation for dormant Li-ion (mains or PV can trigger activation).
- Charging modes & scheduling: Solar only, mains priority, solar priority, and mixed mains + PV charging; time-slot charging/discharging for Time-of-Use (TOU) peak/valley tariffs; battery discharge time can be set to zero for UPS power supply use.
- Parallel scalability: Up to 6 units in parallel (up to 72kW stated) for home, commercial, or industrial systems.
- LCD monitoring: Large LCD with real-time photovoltaic system operating data and dynamic flow diagram.
- Interfaces: RS485, CAN, USB, and Dry contact; supports inverter and battery BMS communication with SOC/SOH visibility.
- Protection: 360° protection including short circuit, over current, over voltage, under voltage, over-load, backfill, over-temperature, and over charge protection.
