Product Overview
A 24V, 0.5HP three inch pump giving up to 4000 litres and 35 metres of head, with double bearings for higher axial load.
Two, three and four inch DC brushless submersible solar pumps with MPPT controllers, stainless steel shafts and dry-run protection.
Key Benefits
- Permanent magnet DC brushless synchronous motor
- 304 stainless steel pump shaft
- Double bearing, motor base works better under more axial pressure
- Alloy mechanical seal, longer working life and high reliability
- Intelligent water shortage protection
- MPPT controller
Who It Is For
Irrigation and livestock buyers, village water schemes, and distributors serving farms beyond the grid.
Problems It Solves
- Diesel pump sets cost fuel every day and break down far from a workshop.
- A pump that runs dry burns out its seal and its motor.
- Buyers do not know which model matches their head and flow.
Application Scenarios
- Field irrigation
- Village water points
- Livestock and poultry farms
Technical Features
- Permanent magnet DC brushless synchronous motor
- 304 stainless steel pump shaft
- Double bearing, motor base works better under more axial pressure
- Alloy mechanical seal, longer working life and high reliability
- Intelligent water shortage protection
- MPPT controller

Quality Control
- Micro-programmed control units on the lighting products protect against over voltage, over current, over charge, over discharge and short circuit.
- Solar panels are quoted at a 5 to 10 year lifespan and LED bulbs at 50,000 hours.
- Products are stated to meet ISO, SGS, BV, COC, PVOC, SONCAP, SASO, CIQ, CE and RoHS requirements.
- The company's own lamp development passed the Indonesian laboratory test before volume supply.
- Certified models are tested by third parties: VeraSol certification on the SunAwada, VeraSol testing on the SunAce-Li, and the Lighting Global quality standards on the Lamp2Torch, SunAce II and SunBase.
How It Is Manufactured
Tooling and moulding
Housings start from our own moulds. The company built its moulding capability when it developed the Indonesian SEHEN lamp, and that is still where a new housing begins.
Component sourcing and incoming check
Cells, panels, LEDs and control boards are sourced and checked before they reach the line. Cost engineering happens here, not by thinning the specification later.
Board and wiring assembly
Charge control, protection and, on PAYG models, the token firmware are fitted and wired to the lamp and output ports.
Line assembly
Housings, panels, cables and accessories are assembled and packed at the Shenzhen workshop. Lantern supply ability is quoted at 100,000 pieces per month.
Function and run test
Charge, discharge, brightness step and protection behaviour are checked before the unit is boxed.
Packing and loading
Retail cartons and export packing, with container loading figures confirmed per model before shipment.
Certifications
Certification on request
Certification for this model is confirmed in writing with the quotation. We do not publish a certificate we cannot supply.
Customisation Options
- Model selected against your head and flow requirement
- Voltage and horsepower matched to the array you plan to install
- Controller and accessory pack specified with the pump

Use Guide
- Calculate the head
With a water tank, the head is the distance B plus C plus D divided by ten. Without a tank it is distance B.
- Decide the flow you need
Work out how much water you want per hour or per day, then match the head and flow against the pump model table.
- Size the array to the pump voltage
The two and three inch pumps are 24V and the four inch is 48V. The MPPT controller sits between the array and the pump.
- Install with the dry-run protection connected
Water shortage protection stops the pump when the well runs dry and restarts it 30 minutes later. It only works if it is wired in.
- Read the controller display
The four inch controller shows power, voltage, current and speed, which is the fastest way to see whether the array or the well is the limit.
