Powercom SLK-4000 Solar King (SLK-4000-UL) 240V 4000W Sine Wave PV Inverter - Retail
Manufacturer: Powercom USA
MFR Part #:SLK-4000
Condition: New
Packaging: Retail
Description
The most advanced grid-tie PV inverter in the world. Converting sun light into electricity energy for home / industrial applications, and powering up our world with free solar energy is now no longer just a dream.
Features
Anti-Islanding detection methods: Frequency, voltage and utility impedance.
Build-in MPPT (Maximum Power Point Tracking) function.
High efficiency with wide range operation.
Design to meet UL-1741 or CSA Std.C22.2 No.107.1-01 requirements.
Easy assembly in production line.
Easy replacement when servicing. The mean time of service is less than 20 minutes.
Firmware flash capability: The firmware inside the micro-controllers can be updated by optional communication interface.
GFCI: Ground Fault Current Interruption, which is also known as RCD (Residual Current Device). To prevent electrical hazard of user, a current transformer monitoring the difference between L and N current is applied. When the current difference is larger than specified value stated in section “General Data”, inverter will cut its output to grid.
Bundled software for user buying optional communication card.
UL1741 certified.
