The Deye 4D1500/SC25-26G is a 4-inch, 1500 W DC solar water pump for high flow at low lift: up to 25 m³/h, but a head of only up to 26 m (21 m³/h at 8 m). It has a stainless steel impeller. Choose it when you need a lot of water from a small lift; if water must be lifted above 26 m, choose the 4D1500/PC13-60G or 4D1500/SC11-60G (up to 60 m) or the 3D1500/PC3.8-180G (up to 180 m). It runs directly from solar modules with no inverter and has IP65 protection.

How the 4D1500/SC25-26G differs from the other Deye 1500 W pumps
All four Deye models have 1500 W of power, the DYD-1500DC controller and IP65 protection; they differ in size, impeller, flow and head.
| Parameter | 4D1500/SC25-26G | 3D1500/PC3.8-180G | 4D1500/PC13-60G | 4D1500/SC11-60G |
|---|---|---|---|---|
| Pump size | 4 in | 3 in | 4 in | 4 in |
| Impeller | stainless steel | plastic | plastic | stainless steel |
| Maximum flow | 25 m³/h | 3.8 m³/h | 13 m³/h | 11 m³/h |
| Maximum head | 26 m | 180 m | 60 m | 60 m |
| Outlet diameter | not stated | 1.25 in | 2 in | 1.5 in |
Choose the 4D1500/SC25-26G if you need a lot of water (up to 25 m³/h) and the lift is small, up to 26 m. If water must be lifted higher, look at the 4D1500/PC13-60G (plastic impeller) or the 4D1500/SC11-60G (stainless steel impeller): both lift up to 60 m, but their flow is up to 13 and 11 m³/h. For the highest lift there is the 3D1500/PC3.8-180G (up to 180 m, 3.8 m³/h).
Who is the 4D1500/SC25-26G solar water pump for?
The Deye 4D1500/SC25-26G suits jobs that need a lot of water from a small lift: the curve shows 21 m³/h at 8 m and 24 m³/h at 3 m. The manufacturer names these uses: remote sites, agricultural irrigation, livestock watering and home water supply.
How much water does the 4D1500/SC25-26G pump and how high can it lift it?
The maximum flow of the Deye 4D1500/SC25-26G is 25 m³/h and the maximum head is 26 m, but the two limits are not reached at the same time: as the head increases, the flow drops. The manufacturer’s curve shows how this works in practice. The manufacturer’s curve reaches 24 m³/h, while the stated maximum flow is 25 m³/h.
| Flow, m³/h | Head, m |
|---|---|
| 0 | 26 |
| 21 | 8 |
| 24 | 3 |
Solar water pump without an inverter: power and control
The Deye 4D1500/SC25-26G needs no separate inverter: the DYD-1500DC controller takes its power from the solar DC input only, with a maximum input current of 20 A. The controller has solar MPPT and an LCD screen, and the pump stops automatically when the water tank is full. All six protection functions are listed in the specifications table.
What to know before buying a solar water pump
- Impeller: stainless steel.
- Outlet: the diameter is not stated on the manufacturer page.
- Flow and head: up to 25 m³/h and up to 26 m, but not at the same time: 21 m³/h at 8 m. The curve ends at 24 m³/h, while the stated maximum flow is 25 m³/h.
Frequently asked questions
Does the Deye 4D1500/SC25-26G need an inverter?
No, the Deye 4D1500/SC25-26G runs directly from solar modules without an inverter, because its DYD-1500DC controller has solar MPPT and a direct DC input.
How much water does the Deye 4D1500/SC25-26G deliver?
The maximum flow of the Deye 4D1500/SC25-26G is 25 m³/h. Flow drops as the head increases, so check the exact figures in the manufacturer’s curve above.
How high can the Deye 4D1500/SC25-26G lift water?
The maximum head of the Deye 4D1500/SC25-26G is 26 m. The pump reaches that head at zero flow: the more water it delivers, the lower the head, as the curve above shows.
How much does the 4D1500/SC25-26G deliver at an 8 m head?
According to the manufacturer’s curve, the Deye 4D1500/SC25-26G delivers 21 m³/h at an 8 m head.
How many solar modules does the 4D1500/SC25-26G pump need?
The manufacturer does not state the number or power of modules required. Hybrid Energy selects a suitable set of modules for your water source and the flow you need.
What happens when the water tank is full?
The Deye 4D1500/SC25-26G stops automatically when the water tank is full.
How does the 4D1500/SC25-26G differ from the other Deye 1500 W pumps?
The 4D1500/SC25-26G delivers the most water, up to 25 m³/h, but lifts only up to 26 m, while the other three models lift up to 60 m and 180 m. See the comparison above.
What protection rating and safeguards does the 4D1500/SC25-26G have?
The Deye 4D1500/SC25-26G has an IP65 protection rating and six protection functions, including reverse-connection and open-phase protection.
Is the 4D1500/SC25-26G a deep-well solar pump?
The manufacturer states a maximum head of 26 m for the Deye 4D1500/SC25-26G, but does not state the submersion depth or the borehole diameter. Before you buy, Hybrid Energy assesses your water source with you and selects a suitable solution.
Do you deliver and install the 4D1500/SC25-26G in Lithuania?
Yes, Hybrid Energy delivers the Deye 4D1500/SC25-26G anywhere in Lithuania, installs it and connects it. A consultation before purchase is free.
