SOLAR TO KEB Automatic change over
With GSM MOBILE monitoring feedback system
*Circuit Explanation & Connections*
This circuit switches between KEB (grid) and Solar power using voltage sensing relays (VSP) and contactors (CONTA, CONTB) with interlocking for safety.
KEB Side: KR, KY, KB (3-phase) go to VSP1, which controls Contactor A (CONTA). The NC contact of CONTB is in series with KY, ensuring Solar and KEB don’t activate together.
Solar Side: SR, SY, SB (3-phase) go to VSP2 (with NC relay), which connects to a 10s delay timer (MONO 10S). After 10 seconds, MONO 10S energizes Contactor B (CONTB). The NC contact of CONTA prevents KEB activation when Solar is ON.
This setup ensures automatic, stable switching between power sources, preventing conflicts and protecting against voltage fluctuations.
