Solar Water Heater Pump TD5 is a solar power dc pump,SID Laing Ecocirc D5 Solar Direct Circulation Pump
The most powerful and safe solar DC circulation pump for direct connection to photovoltaic panels with automatic performance optimization using MPPT technology
Stainless Steel Solar Water Pump TD5,The most powerful and safe solar DC circulation pump for direct connection to photovoltaic panels with automatic performance optimization using MPP technology. (Maximum Power Point tracking)
• Configure the DIP switch speed regulation function: matching with 4 types solar power panel
• The lowest starting power 2W
• MPPT function
• High temperature 110°C (230°F),high pressure 10bar
• Wide operating voltage range
• Long lifespan 30000hour
• Over voltage protection
When the voltage over 28V, the pump will auto-protect and shut off own power supply, when the voltage falls below 28V, the pump will restart automatically.
• Over load protection function
This means that when the current is over the rated current, such as can arise if the impeller is stuck due
to debris. The pump will automatically stop to prevent damage, and will restart when the current falls again.
• PV operated
For solar system loops, the TD5 Solar pump can be powered directly from a PV panel. Thesun comes up, heat builds in the solar hot water panel and at the same time electricity is made in the PV panel.The pump slowly starts with the smallest amount of current and pushes the heated water to the storage tank. It’s all too simple and eliminates all controllers, thermostats and sensors.
• Soft start-up
The TD5 Solar DC pump has a soft start-up feature which reduces high in-rush current. When the photovoltaic panel provides sufficient power,the pump goes through the alignment phase by turning the rotor into the position required for start-up. The processor then waits until the capacitor is sufficiently charged. This enables a start-up with minimal power (less than two watt).Cycling due to unsuccessful attempts is minimized. Even after prolonged shutdown, the
pump will start reliably .
• Automatic polarity protection
Red is plus, black is minus, if wrong polarity will not damage the motor for it has the automatic polarity protection function.

Advantages over solar pumps from EL SID Solar DC Pump and Laing D5 Solar Pump
Many of our clients also reflected application problems by using SID and Laing-D5 pumps, such as tempreature, MPPT max efficiency and so on. But they are very satisfied with ours till now since transition. Our TS5&TD5 solar pumps are developed by studying SID and Laing-D5 pumps first,
–Motor
–MPPT functions
Then optimize their weakness. For example, there exists tempreature issue due to spherical motor for Laing D5 pumps, and SID pumps do not have MPPT functions. Generally, our solar pumps have comprehend all advantages and optimize the advantages for supporting solar system at its max performance, and have been tested and applied in the market for a long time with nice feedback. I believe topsflo will be a great choice for you.
| No. | Weakness | Improvement |
| 1, Motor | tempreature issue due to spherical motor for Laing D5 pumps | High efficiency ECM brushless DC motor, reach clients’ requirements in long lifetime and over all performance. |
| 2, MPPT function | SID pumps do not have MPPT functions | TD5 with MPPT function, can realize four powers, 5W, 10W, 15W, 25W automatically wuth hiest efficieny. |
| 3, Structure&Design | SID&Laing D5 | More reasonable and nicer-looking |
