Frequently Asked Questions
Do I need batteries, or can this run directly from solar panels?
The 100PV 2.2KW inverter supports both direct solar and battery configurations. For daylight-only pumping, connect solar panels directly (250V-450V DC range). For 24/7 operation or consistent flow requirements, add a 48V or 96V battery bank. The MPPT controller automatically optimizes panel output voltage (typically 30-40V per panel, 8-12 panels in series). No battery is required for basic solar pumping applications.
Can this inverter work with my existing single-phase submersible pump?
Yes. The 100PV outputs standard single-phase 220-240V AC at 50/60Hz, compatible with conventional single-phase induction motors and pumps up to 2.2KW (3HP). It provides soft-start functionality to reduce inrush current by 60%, protecting pump windings and extending motor life. For pumps over 100m depth, verify starting torque requirements against the inverter’s 150% overload capacity (60 seconds).
What happens when solar irradiance drops or clouds pass over?
The MPPT algorithm tracks maximum power point every 2 seconds, automatically adjusting motor speed to match available solar power. During cloud cover, the inverter reduces output frequency proportionally rather than shutting down—maintaining water flow at reduced rates. If input voltage drops below 200V DC, the inverter enters standby mode and auto-restarts when sufficient power returns. Optional battery backup eliminates flow interruption entirely.
What is the warranty and expected lifespan?
The 100PV series includes a 2-year standard warranty with 5-year extended coverage available. Designed for 15+ year operational lifespan with IP65-rated aluminum enclosure, conformal-coated PCBs, and passive cooling (no fan failures). MTBF exceeds 50,000 hours. Technical support includes remote diagnostics via RS485 and field service coordination for critical agricultural installations.
