Details
The PowMr SP5.2K hybrid inverter delivers 5200W pure sine wave power with a 100A MPPT charge controller and up to 6000W PV input.
A backlit smart LCD and three status LEDs provide quick visibility into solar, mains/generator, battery, and load conditions.
Time-control scheduling helps align charging and discharging with peak and off-peak electricity rates using definable time periods.
Flexible battery support covers common lead-acid types and lithium batteries, and the system can also power loads without a battery connected.
Four selectable charging modes make it easy to prioritize solar, grid power, or a mix of both to match your setup.
Built-in electrical protections help safeguard the inverter and connected loads during abnormal conditions.
The 51.2V 100Ah LiFePO4 battery supports up to 100A charging, with a recommended lower charge current for long-term service life.
LiFePO4 storage offers higher energy density and long cycle life compared with lead-acid batteries at similar capacity.
RS485/CAN communication and a wall-mount design support clean installation and real-time integration with compatible inverters.
