Uni-Pump Compact Solar Replacement Pump – MPPT Battery Backup

Energy Collection

• The panel captures sunlight and converts it to electrical energy
• Energy powers the pump directly or charges the battery (in backup models)
• System activation depends on light intensity and system type
• Performance varies significantly with weather conditions

System Types

• Direct Systems: Function only with sufficient direct sunlight
• Battery-Backed Systems: Store energy for more consistent operation
• Hybrid Systems: Combine immediate operation with energy storage
• Each type offers different benefits based on your specific needs

Direct Systems Performance

• Operation strictly dependent on available sunlight
• Flow varies continuously with passing clouds
• May start and stop multiple times on partly cloudy days
• Strongest performance during midday hours with direct sun
• No operation during evening or heavily overcast conditions

Battery-Backed Systems Performance

• More consistent operation throughout the day
• Continues running during brief cloudy periods
• Provides operation after sunset (typically 1-8 hours depending on model)
• Maintains steadier flow rate regardless of minor light variations
• May include adjustable flow settings and timer functions

Summer Performance (May to August)

• Peak performance period for all system types
• Direct Systems: Operation possible from early morning to evening on clear days
• Battery Systems: Consistent daytime operation plus evening hours
• Maximum flow rates achieved during direct midday sun
• Best charging efficiency for battery models

Spring/Autumn Performance (March-April, September-October)

• Reduced operational hours with shorter daylight
• Direct Systems: Expect 40-60% of summer performance
• Battery Systems: More reliable operation but reduced evening hours
• Performance varies significantly with weather conditions
• Panel angle adjustment becomes more critical

Winter Performance (November-February)

• Significantly limited operation for all systems
• Direct Systems: May only operate briefly during peak sun (5-10% of summer performance)
• Battery Systems: Limited daytime operation with minimal evening hours
• Many customers choose to store system during winter months
• Performance highly dependent on clear, sunny conditions

How MPPT Works

• Continuously optimizes solar panel output
• Automatically adjusts to changing light conditions
• Previously only available in industrial systems

30% Efficiency Boost

• Enhanced performance in lower light
• Faster battery charging
• Longer operating hours

PowerBee Innovation

• First in small pumps
• Professional-grade technology
• Sets a new industry standard

Seasonal Panel Positioning

To maximize energy capture, adjust the panel angle based on the sun's position throughout the year. In the UK:

• Winter (Nov-Feb): Position at 60°
• Spring/Autumn: Adjust to 40°
• Summer: Set at 20-30°

Critical Installation Factors

• Panel facing south for max exposure
• No shading — even partial shade reduces output
• Clean weekly for max efficiency
• Sun all day with no obstruction
• Keep battery units dry & ventilated

Direct-Powered Systems

• Maintenance-free operation
• No moving parts beyond pump
• Lower upfront cost than battery systems
• Best for daytime use
• Ideal for sunny locations

Battery-Backed Systems

• Operation in variable weather
• Runs during cloudy periods + evenings
• Many include timers
• Low-battery protection
• Best for constant circulation

Regular Care

• Clean panel weekly
• Clean pump filter monthly
• Check all connections
• Inspect cables
• Adjust panel seasonally

Battery Maintenance

• Keep battery dry & ventilated
• Allow full charge cycle periodically
• Store indoors in extreme cold
• Check for corrosion
• Replace after 18–24 months

Winter Storage Recommendations

• Remove system during winter
• Clean before storage
• Store in frost-free location
• Battery fully charged
• Inspect before reinstall in spring

Winter Operation

• Expect ~5–10% of summer capacity
• Direct systems may not operate
• Battery systems offer limited function
• Panel at 60° angle
• Protect pump from freezing
