התרחיש
A 10 kWp solar array feeds a VFD that drives a 7.5 HP three-phase submersible pump. The system is direct-coupled with DC isolation, surge protection and a DC-link capacitor for stable operation.
מה מופיע בתרשים הזה
פענחו את ההחלטות שמאחוריו.
01
Direct-coupled PV array without battery storage
02
VFD converts DC to three-phase AC for soft-start and motor protection
03
DC disconnect and fuse protect the array and inverter input
For off-grid farm irrigation where solar PV drives an AC submersible pump directly; adapt array kWp and VFD rating to pump size.
