The total rated Maximum Power Current (Imp) of the PV input should not exceed
30 amps.
The GP-PWM-30 will limit PV current above 30 Amps. Although the GP-PWM-30
will accept PV current greater than 30 Amps for a short duration, damage may occur if the
GP-PWM-30 operates continuously with greater than 30 Amps of PV input.
