DOYIN AD Hybrid Controller 800W (DYS-90AD)

The DOYIN DYS-90AD is an 800W AC/DC hybrid controller designed to power submersible water pumps from either solar panels or grid electricity. This flexibility suits coastal Kenyan properties in Mombasa, Malindi, Diani, Kilifi, and Lamu, where solar can drive the pump during daylight hours while grid power (where available) provides backup during cloudy spells, early mornings, or evenings.

Rated for 800W pump systems, the DYS-90AD is matched to DOYIN's entry-level hybrid submersible pump model — the 4SDS5-800W (1.0HP) AD — which specifies this controller as its compatible AD unit. Always confirm your specific pump model's wattage matches this controller before installation, as running a pump with a mismatched controller can damage the motor.

This controller suits smaller domestic boreholes and household water points needing dependable output regardless of solar conditions. For coastal properties with inconsistent grid supply, the hybrid switching capability reduces water supply interruptions compared to a solar-only or grid-only setup.

CoastalSolar Africa supplies and installs the DYS-90AD hybrid controller, matched correctly to your DOYIN pump model, across the coastal region.

FAQs:

What does "AD" mean on this controller?
AD stands for hybrid AC/DC — meaning the controller can run your pump on either solar power or standard grid electricity.

Which DOYIN pump uses the DYS-90AD controller?
It's rated for the 800W (1.0HP) 4SDS5-800W AD pump model in the DOYIN range. Confirm your exact pump model with CoastalSolar Africa before purchase.

Can I use this controller with a solar-only pump?
It's designed for hybrid AC/DC operation. If your pump is DC-only, a standard DC controller (like the DYS-90) matched to your pump's wattage is the correct choice instead.

Why choose a hybrid controller over a DC-only one?
A hybrid controller lets your pump keep running on grid power when solar output drops, useful for coastal areas with cloudy spells or higher water demand during non-daylight hours.

Do you supply and fit this controller in Kilifi and Malindi?
Yes, CoastalSolar Africa supplies and installs the DYS-90AD controller, correctly matched to your pump model, across Mombasa, Malindi, Diani, Kilifi, Lamu, and the wider coastal region.
