Overview
The PowMr POW-SunSmart 12KPL3 is a 48Vdc 12,000W three-phase solar inverter with pure sine wave output and dual MPPT solar charge controllers. It supports 230/400Vac three-phase output, adjustable phase voltage settings (200/208/220/230/240Vac), and PV input up to 800Vdc (800Vdc/800Vdc).
Key Features
- Three-phase pure sine wave output: supports three-phase output (350~415V) with selectable phase voltages of 200/208/220/230/240Vac.
- Dual MPPT: 2 MPPT with MPPT tracking efficiency up to 99.9%; max input current 22/22A; supports two PV inputs and simultaneous MPPT tracking.
- High charging capability: max hybrid charging current 260A; total 260A charging; each PV input described as 9000W input.
- 48V battery support: compatible with lead-acid and lithium-ion batteries; supports dormant Li-ion activation triggered by either mains or PV access.
- Parallel expansion: up to 6 units in parallel (described as scalable to 72kW).
- Time-based energy control: time-slot charging/discharging for Time-of-Use (TOU) peak/valley tariffs; sectioned charging function (BT1ST) and sectioned discharge function (AC1ST); battery discharge time can be set to zero for UPS power supply use.
- Monitoring & communication: LCD HD display screen for real-time PV system operating data; interfaces include RS485, CAN, USB, and dry contact; supports inverter and battery BMS communication with SOC and SOH display.
