DOYIN DC Controller 600W (DYS-60)

The DOYIN DYS-60 is a 600W DC controller built specifically for solar-only submersible water pumps, managing power delivery from your solar array directly to the pump motor without any grid-power switching capability. It's a dependable, entry-level control option for off-grid coastal properties in Mombasa, Malindi, Diani, Kilifi, and Lamu where the pump will run purely on solar throughout its operating life.

Rated for 600W pump systems, the DYS-60 is matched to DOYIN's 0.75HP DC submersible pump models — including the 3SDS4-600W (0.75HP), 4SDS5-600W (0.75HP), and 4SPS4.5-600W (0.75HP, stainless steel impeller) pumps, all running on a DC voltage range of 65–100V. Panel array size varies slightly by model: the 3SDS4-600W and 4SDS5-600W pair with 2 x 410W panels, while the stainless steel 4SPS4.5-600W pairs with 2 x 450W panels. Always confirm your specific pump model's wattage and voltage match 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 where solar is the sole power source and grid backup isn't required or available.

CoastalSolar Africa supplies and installs the DYS-60 DC controller, matched correctly to your DOYIN pump model and solar array, across the coastal region.

FAQs:

What's the difference between the DYS-60 and DYS-60AD?
The DYS-60 is DC-only and works with solar power alone. DOYIN's AD hybrid controller range starts at 800W, so there is no direct hybrid equivalent at this power level in the current catalog — CoastalSolar Africa can confirm current options if you need grid backup.

Which DOYIN pumps use the DYS-60 controller?
It's matched to 600W (0.75HP) DC pump models, including the 3SDS4-600W, 4SDS5-600W, and the stainless steel impeller 4SPS4.5-600W, all requiring a 65–100V DC input.

Does the panel setup differ between these pump models?
Yes — the 3SDS4-600W and 4SDS5-600W use 2 x 410W panels, while the stainless steel 4SPS4.5-600W uses slightly higher-rated 2 x 450W panels.

Do I need to match the exact voltage range?
Yes, correct voltage matching between panels, controller, and pump is essential — CoastalSolar Africa can confirm your array configuration before installation.

Do you supply and fit this controller in Kilifi and Malindi?
Yes, CoastalSolar Africa supplies and installs the DYS-60 controller, correctly matched to your pump model and solar array, across Mombasa, Malindi, Diani, Kilifi, Lamu, and the wider coastal region.
