Key electrical tests for this grid-tied inverter setup include insulation resistance testing, polarity checks, and open-circuit voltage (Voc) testing on the DC side. The AC side is then verified for correct grid voltage and frequency before a controlled, sequential power-up.

Solar panel count: For a 1HP pump, you typically need 4 to 6 panels rated between 250W to 400W each, depending on their voltage and the system's efficiency. Input voltage range: Ensure the total voltage from your panels falls within the inverter's MPPT input range.
