Description
The SR-16 is SunRotor’s high-capacity multi-stage centrifugal submersible built for projects that need big daily gallons and the ability to lift from deeper static levels.
Its stacked-impeller hydraulics make strong pressure at modest PV input, so the pump starts early, runs late, and maintains steady flow as head rises—ideal for ranch tanks, storage fills, and remote homesteads where uptime matters.
Paired with the SRC-M200T DC controller, the SR-16 accepts solar, battery, or hybrid input and converts excess array voltage into useful pumping current. Above-ground electronics, clear status LEDs, low-water/tank-full inputs, and linear current boosting keep performance predictable and service straightforward.
Product Details
-
High lift & real flow: Capable of substantial head with strong output; designed for efficient daily gallons in the 50–300 ft working range.
-
Controller-ready system: Runs with the SRC-M200T (72 V nominal bus, 200 VDC max input), enabling solar, battery, or blended operation with low-water and float-switch terminals.
-
Installer friendly: 3.75" diameter body fits standard 4" casings; 1.25" FNPT outlet; all electronics mounted above ground for easy access and longer life.
-
Built for longevity: Brushless DC motor, 304 stainless steel body and impellers, oil-jacketed motor section for potable-water safety, and conservative thermal protections.
-
Field use advantages: Early-start/late-run behavior, linear current boost through changing irradiance, and documented array recipes for different lift targets.
