Configuration based on 37Voc (±1V) or 45Voc (±1V) solar modules. Actual panel configuration may vary based on local irradiance and pump requirements. Contact our engineering team for site-specific designs.
Yes. The 100PV series features seamless AC/DC auto-switching technology. When solar power is insufficient or unavailable, the system automatically switches to AC grid power (if available) without stopping the pump or requiring manual intervention. For AC/DC simultaneous operation, custom configuration is available upon request.
The 100PV series supports both asynchronous (standard AC induction) and synchronous pumps. By factory default, it is configured for DC input with asynchronous pump control. Synchronous motor pumps and AC/DC simultaneous access require customization—please specify your pump type when ordering. Compatible with submersible borehole pumps and surface centrifugal pumps from 0.4KW to 2.2KW.
The integrated GPRS module enables cellular communication between the inverter and your smartphone via a dedicated mobile app. You can remotely monitor real-time parameters (PV voltage, pump speed, flow rate), receive fault alerts, start/stop the system, and adjust operational settings from anywhere with mobile coverage. This eliminates site visits for routine checks and enables rapid fault response.
Yes. For models ≤2.2KW, an optional boost module is available that enables low-voltage pump operation. This allows the system to function with fewer solar panels in series, significantly reducing both equipment costs and installation complexity while maintaining 99% MPPT efficiency. Ideal for budget-constrained agricultural projects.
The 100PV includes comprehensive protection: PV over-voltage and over-current protection, automatic derating when internal temperature exceeds safe limits, dry-run detection (prevents pump damage from running without water), and intelligent water level monitoring. Optional IP54-rated cabinets provide additional environmental protection for dusty or humid installations.
AC/DC simultaneous access and synchronous pump compatibility require factory customization.
Standard configuration defaults to DC input for asynchronous pump control. Please specify your exact requirements when requesting a quote.
Our engineers provide complimentary solar pump system sizing, panel configuration optimization, and remote monitoring setup.
Bulk pricing available for agricultural cooperatives and irrigation projects.
