Found a better price elsewhere? We’ll beat it.
The Tuhorse 4S500-40/400 Solar Bore Pump Package is a complete off-grid pumping kit built around a 4" 500W/48V stainless steel helical rotor pump with 2 x 200W monocrystalline solar panels, an MPPT auto control box and 20m of fitted power cable. It suits bore depths from 10m to 25m, drawing from bores, rivers, dams, creeks and springs with no mains power, inverter or battery bank required.

A Complete Off-Grid Water Supply
This is a full package rather than a bare pump. The panels, control box, power cable, water sensors and a spare rotor all arrive together, so the only site work is mounting the panels, dropping the pump and running the poly pipe.
Because it is a helical rotor pump running directly from the panels, there is no inverter and no battery bank to buy or maintain. Once installed it costs nothing to run.
Helical Screw Rotor Pumping
The pump uses a helical screw rotor rather than an impeller. That design holds pressure at low speed, which is what lets it keep delivering water in weak morning and afternoon light instead of only at midday.
The rotor is a wear part, and Tuhorse supplies a spare in the box.
Flow at Head
Output depends on how far the water has to be lifted. This package delivers 15 L/min at 25m, 17 L/min at 20m, 27 L/min at 10m.
Daily figures are based on 6 to 8 hours of peak sun per day in winter and 8 to 10 hours in summer.
| Head | Flow | Gallons per Hour |
|---|---|---|
| 25m | 15 L/min | 200 gal/h |
| 20m | 17 L/min | 267 gal/h |
| 10m | 27 L/min | 360 gal/h |
MPPT Auto Control Box
The control box runs maximum power point tracking, so it keeps pulling the best available power out of the panels as light conditions change through the day.
It takes two water sensors, one for the bore and one for the tank, so the pump stops on low bore water and again when the tank is full. Motor speed is adjustable and low power protection is built in.
Input voltage is accepted up to 100V/DC (solar panel open circuit maximum).

Installation Information
The package is designed to be plug and go, but a few items are deliberately not included so they can be matched to your site.
Important installation considerations include:
- A stainless steel safety cable is required to hold the pump in the bore.
- If pumping from a dam or river, a float set-up is required instead.
- Panel frames and mounting posts are needed to support the solar panels.
- Poly pipe from the pump to the tank is not supplied.
- Do not submerge the pump deeper than 30m.
- The bore sensor and tank sensor must both be positioned before commissioning.
- Electrical work should be carried out by a licensed electrician where required.
- Confirm your bore depth and daily water requirement against the flow table above before ordering.
