Frequently Asked Questions

Does this system require batteries to operate?

No, the system is designed to drive the pump directly using solar power. It uses water storage (in tanks or reservoirs) instead of expensive battery storage to reduce maintenance and construction costs.

What is the benefit of the MPPT algorithm?

The VI Maximum Power Point Tracking (MPPT) algorithm ensures fast response and stability, maximizing the power output from the solar array even when sunlight intensity changes rapidly.

Can the pump work in low sunlight conditions?

Yes, the inverter utilizes advanced Variable Frequency Driver (VFD) technology, allowing the pump to operate at adjusted speeds during periods of less sunshine, ensuring maximum utilization of available energy.

Is the system easy to monitor remotely?

The inverter is equipped with an LCD panel for local setting and monitoring. It also offers an optional RS485 communication interface for remote data monitoring.

What kind of protections does the inverter offer?

The unit includes a complete range of protections: PV over/under voltage, reverse polarity, output overload, short circuit, dry well protection, overflow protection, and blocking protection.
