Easy operation:connect your solar panel(DC10.5V to DC28V ) to this grid tie inverter and plug the AC power to your home power socket.If your power system need the Wide Input Voltage,try to reference our Low frequency series. In order to achieve higher power use requirements, the use of this product can be stacked, such as: 4 grid inverter 1KW of stack used is equal to 4KW. Feature: - Generates pure sine wave - Automatic power adjustment - Constant Power Output - Low distortion output on all ranges - Allow different Power factor from loads - Compact and light weight design - Maximum Power Point Tracking (MPPT) - optimize power output - Plug and Play Design, simply plug into an outlet (GFI), no hard-wiring - Stackable (connect in parallel for higher output) - Aluminum enclosure will act as heat sink to help dissipate heat - Simple and safe installation - Island protection: Inverter will shut down during black outs. - Grid-Tied - sell green power directly back to the grid at a premium rate (depends on your location) Specification: Grid-inverter Type: YTP-800 Recommended Maximum PV Power: Ppv=1040Wp DC Maximum Input Power: PDC.max=880W DC Maximum Voltage: VpvDC28VDC PV MPPT DC Voltage Range: Vpv 10.5V~28DC Peak Inverter Efficiency: max>94% Power Factor: 0.93-0.99 PV Maximum Input Current: Ipv.max50A Reverse Polarity Protection : Fuse AC Rating Output Power: 750W AC AC Maximum Output Power: 800W AC AC Normal Voltage Range: 80V-130;160~260VAC AC Frequency: 45-65Hz Inverter Output Current Total Harmonic Distortion: THDIAC
