Rocksolar 1.07HP 65-110V Solar DC Water Transfer Pump Kit

ROCKSOLAR 1.07HP 65–110V Solar DC Brushless Water Transfer Pump Kit

What's included:

• 1 × 1.07HP 65–110V DC brushless water transfer pump + MPPT controller
• 3 × 440W rigid monocrystalline bifacial solar panels (1,320W array)
• 10 ft 10 AWG PV cable
• 1 × 2-string waterproof DC disconnect box with 1000V 40A circuit breaker
• Mounting brackets for solar panels (optional)
• Ground or roof mount rack (optional)
• User manuals + warranty card

Key specs:

• Motor: 1.07HP DC brushless | Input: 65–110V DC
• Max flow rate: 24.2 GPM | Max head: 98 ft
• Protection rating: IP54 (pump) / IP65 (controller)
• Controller-to-motor cable distance: up to 80m
• Solar array: 3 × 440W bifacial panels (1,320W)

Built for: Livestock watering, agricultural irrigation, pool fountains, ponds, greenhouses, orchards, remote off-grid water supply

Key features:

• Higher voltage range (65–110V) = supports 3-panel string for larger solar array and higher flow output vs. the 40–90V model
• 24.2 GPM max flow = significantly higher volume than the 40–90V kit's 9.6 GPM — suited for larger irrigation or livestock operations
• Up to 80m controller-to-motor cable distance = flexible installation, pump and controller can be far apart
• MPPT controller — auto-adjusts to available sunlight, stops and restarts without manual intervention
• Float switch / pressure switch compatible — automates tank fill and shutoff
• IP54 pump + IP65 controller — permanent outdoor installation ready
• Advanced protections: dry-run, overload, overvoltage, low-voltage

How the System Works

The ROCKSOLAR Solar Powered Water Pump System converts solar energy into a reliable water supply for livestock watering, irrigation, and remote agricultural applications.

The operating sequence is as follows:

1. Solar panels convert sunlight into direct current (DC) electricity.
2. The solar pump controller continuously monitors the available solar power and adjusts the voltage and current to maximize energy harvest from the solar array.
3. The controller supplies optimized DC power to the brushless submersible pump, ensuring efficient operation under varying sunlight conditions.
4. The pump draws water with its intake pipeline from the well, pond, cistern, stream, river or other approved water source and delivers it through the discharge pipeline.
5. Depending on the application:
   • Livestock Watering: Water is pumped into a storage tank or watering trough. When an optional float switch is installed, the controller automatically stops the pump once the tank reaches the preset water level and restarts pumping when the water level drops.
   • Agricultural Irrigation: Water is supplied to irrigation systems such as drip irrigation, sprinkler systems, soaker hoses, or storage reservoirs for crop, orchard, greenhouse, vineyard, pasture, and garden irrigation. Flow can be controlled using irrigation valves, timers, or storage tanks based on the specific irrigation design.
6. During periods of insufficient sunlight, such as early morning, late evening, or heavy cloud cover, the controller automatically reduces pump speed or stops the pump to protect the system and optimize energy use.
7. When adequate sunlight returns, the controller automatically restarts the pump without requiring manual intervention.

This intelligent, fully automatic operation minimizes maintenance while providing a dependable and sustainable water supply for livestock, irrigation, and other off-grid agricultural applications.
