Core Protection & Operational Logic
- Smart Hybrid Switching: Allows dual power inputs to run the pump on solar during peak daylight and switch seamlessly to grid power or a generator when clouds roll in.
- Full Pump Protection Suite: Features automated dry-run prevention (detecting when the well runs out of water), over-current shutdown, motor short-circuit defense, and over-voltage safeguards.
- Tank Level Management: Integrated terminals support water level sensor inputs to stop the pump automatically when your overhead storage tank is full.
