Got a deep borehole and need to lift water all the way to the surface without burning diesel? The Hybsun 3UP1500-125-6E DC solar well pump is the deep-well specialist of the 3UP range — a 1500 W submersible pump that delivers up to 6 m³/h (1585 GPH) at a maximum head of 125 m. That makes it the right pump for the deeper boreholes typical of Cyprus rural and agricultural sites. Whole system needs ≥ 1950 Wp of solar panels (typically 5-6 modern modules).

What It Is
The Hybsun 3UP1500-125-6E DC solar well pump is a submersible borehole pump that runs directly from your solar panels — no grid connection required, no diesel costs, no separate inverter in the loop. Three components make up the entire setup: the submersible pump cylinder (containing the impeller stack and the brushless DC motor at its base), the IP65 controller mounted above ground, and the PV array feeding the controller. The motor at the bottom of the pump cylinder turns the impeller column above it, lifting water up the rising-main pipe to the surface.
Motor Technology
DC Brushless permanent-magnet synchronous motor
Inside the Hybsun 3UP1500-125-6E DC solar well pump is a DC Brushless permanent-magnet synchronous motor — built for high-speed, high-efficiency operation from a solar PV array. The rotating hardware uses NSK industrial bearings (the Japanese-brand standard for continuous-duty pumping) running against an alloy mechanical seal. This bearing-and-seal specification is designed for sustained submersible operation — the duty cycle solar well pumping creates. The dual water-seal arrangement maintains a leak-proof boundary across years of submerged operation.
Every Hybsun 3UP pump ships with its matched DC solar controller — an IP65 waterproof box that sits between your solar panels and the pump. The controller performs MPPT tracking on the PV input, accepts up to 15 A input current, and provides real-time telemetry on its built-in LED panel — input power, voltage, current draw, and motor speed.
A distinctive feature of the 3UP DC controller is the integrated automatic battery charging circuit. An external battery can be optionally connected, with charge/discharge managed by the controller itself. Daytime operation runs the motor from PV while the battery accumulates charge; nighttime operation draws from the battery to maintain pump output — relevant when water demand extends beyond solar hours (continuous livestock supply, scheduled night irrigation, around-the-clock domestic use). Battery connection is entirely optional — the Hybsun 3UP1500-125-6E DC solar well pump operates normally on solar PV alone during the day.
The Hybsun datasheet lists the full protection envelope: soft start (no inrush damage to the motor), over-voltage, under-voltage, over-current, high-temperature and adjustable speed (frequency conversion). For wells that occasionally run dry, the auto-restart is particularly useful — the pump checks again 30 minutes later instead of needing a manual reset.
Unboxing & First Look

Who Should Buy This
The Hybsun 3UP1500-125-6E DC solar well pump is sized for deep wells (up to ~125 m) with daily water needs in the 23-33 m³ range. The buyer profiles below cover the most common situations where this exact pump is the right fit:
Across the Hybsun product line, the well pumps use a common platform: stainless steel construction, NSK bearings, MPPT-based controller, and submersible motor topology. Differentiation between models comes from rated power, maximum head, maximum flow, and AC backup capability. Compare across the range:
Hybsun’s published sizing requirement: minimum PV array power should be ≥1.3 × the pump’s nominal power rating. For the Hybsun 3UP1500-125-6E DC solar well pump that means at least 1950 Wp of solar panels (5-6 panels depending on individual panel wattage). That 30% margin compensates for the standard de-rating factors that bring real-world PV output below the nameplate figure: cell temperature in summer heat, surface soiling, cable I²R losses, and degradation over the array’s lifetime — ensuring the pump runs at design output across the productive solar window.
The Hybsun 3UP1500-125-6E DC solar well pump accepts a PV string running at 110-192 V Vmp, with open-circuit voltage staying <210 V. The voltage tolerance handles real-world variability: panel temperature affects Vmp, passing clouds drop input, and morning/evening sun reduces it further. The controller absorbs all of that and keeps the motor running steadily across the entire daylight window.
This is where the Hybsun 3UP1500-125-6E DC solar well pump really shines. Its performance curve sustains useful flow rates all the way down to 100+ metres of head — well beyond what the smaller 3UP750 can manage. Both pumps share the same 6 m³/h maximum flow on the spec sheet, but the 3UP1500’s curve is shifted dramatically upward: it keeps delivering meaningful water output at depths where the Hybsun 3UP1500-125-6E DC solar well pump simply stops.
Here’s what the manufacturer’s performance curve shows for the Hybsun 3UP1500-125-6E DC solar well pump, with corresponding daily output for a typical 6-hour Cyprus solar day:
Note: “Total dynamic head” includes the static water level depth, pipe friction losses, and the vertical rise to your discharge tank. Pipe friction typically adds 5-15m on top of the static depth (more on longer runs). The manufacturer’s H.Max of 125m matches the curve’s shutoff point.
Both pumps have the same 6 m³/h Q.Max on paper, but their flow-at-depth characteristics are completely different. The 3UP750 is a small pump that hits its limit around 40-48m head. The Hybsun 3UP1500-125-6E DC solar well pump is a high-head pump that maintains useful flow well past 100m. A direct comparison at the same operating point:
So if your borehole has any meaningful depth (anything past about 25-30m static water level), the Hybsun 3UP1500-125-6E DC solar well pump delivers substantially more useful water than the smaller 3UP750 — at any operating point in the deeper part of its range.

The Hybsun 3UP1500-125-6E DC solar well pump is built from stainless steel and plastic — the right materials for the wet, dark, sometimes-aggressive environment inside a borehole. Stainless steel handles the chloride and mineral content of typical Cyprus groundwater; the plastic impellers and diffuser stages inside are specifically there to resist abrasion from sand particles without the metal-on-metal scuffing that affects all-metal designs. In the datasheet Hybsun specifies the build as a “stainless steel oil cylinder” containing a plastic impeller stack — a deliberately-engineered combination for deep submersible service.
The Hybsun 3UP1500-125-6E DC solar well pump uses NSK bearings — a Japanese industrial bearing brand favoured by manufacturers worldwide for continuous-duty rotating equipment. In combination with the alloy mechanical seal and the dual water-seal barrier, the bearing-seal architecture is engineered for the multi-hour daily duty cycles of solar well pumping. Hybsun expressly notes “offering the longer working life” in the spec sheet — design language that matters when the pump assembly sits 30 metres or more down a borehole and isn’t practical to retrieve for routine service.
The controller has a soft-start feature that brings the motor up to speed gradually rather than slamming it on at full power. Soft-start ramping eliminates the inrush current event that progressively degrades brushed-motor and AC-induction-motor windings across thousands of operational cycles — one of the engineering reasons Hybsun is comfortable backing this pump with a 2-year manufacturer warranty under daily-duty conditions.
When dry-well conditions occur (typical during peak summer drawdown), the pump shuts itself down and automatically rechecks the well 30 minutes later. No manual reset, no burned-out motor from dry running. Particularly applicable to boreholes with seasonal variation in static water level.
A distinctive feature of the 3UP DC controller is the integrated automatic battery charging circuit. An external battery can be optionally connected, with charge and discharge managed entirely by the controller. Battery charging occurs during solar input hours alongside normal pumping; the battery then supplies the pump motor during non-solar hours when water demand requires it. Battery integration is optional, not mandatory — particularly worthwhile for sites requiring continuous water supply: livestock watering operations, hotel use, or any installation with substantial off-solar water demand.
Submersible well-pump installation is more involved than a surface pump because the pump goes down inside the borehole. Typical CGP Solar project timeline: site survey and well assessment (2-5 days to schedule — we measure your well depth and static water level), formal quotation (about 1 week), then on-site work — lowering the pump into the borehole on rising main pipe with safety cable (1 day), PV array and controller install above ground (1-2 days), and commissioning under live solar with handover walkthrough (same day). CGP Solar handles installations across all five Cyprus districts — Nicosia, Limassol, Paphos, Larnaca and Famagusta.

FAQ’s
The manufacturer lists H.Max as 125 metres, and the actual performance curve confirms that figure. Unlike the smaller 3UP750 (which loses useful flow past ~40m), the Hybsun 3UP1500-125-6E DC solar well pump maintains meaningful flow rates throughout the deep range: at 40m head you get ~4.8 m³/h, at 60m ~4.2 m³/h, at 80m ~3.6 m³/h, at 100m ~2.7 m³/h, dropping to ~1.0 m³/h as you approach 120m. The 3UP1500 is the right choice for medium-to-deep Cyprus boreholes with a static water level of roughly 30-100 metres (total dynamic head 40-120m once friction is added). For shallow wells under 25-30m, the cheaper Hybsun 3UP750 may be enough; for very high water-volume demand, look at the high-flow Hybsun 4UPH2200 hybrid.
Hybsun specifies PV panel power of at least 1.3 × pump power, so the Hybsun 3UP1500-125-6E DC solar well pump needs at least 1950 Wp of solar panels (5-6 panels depending on panel wattage). The PV string voltage also has to land within the controller’s MPPT range: 110-192 V Vmp, with open-circuit voltage <210 V. CGP Solar designs the exact PV configuration during the quotation stage.
Yes — the 3UP DC solar controller has an automatic battery charging function built in. An external battery is an optional addition — during sunlight hours the controller charges it while simultaneously driving the pump, then draws from the battery for night operation. Useful specifically for installations requiring continuous water availability — livestock operations (animals drink throughout the evening), households with 24-hour demand patterns, or commercial sites with off-solar operational requirements. Battery integration is optional, not mandatory — the 3UP1500 operates entirely from solar PV during daylight hours without it.
If guaranteed continuous operation is critical (commercial water supply, large livestock, hotel use), look at the Hybsun 4UPH2200 AC/DC hybrid well pump instead — it runs from solar when there’s sun and switches automatically to grid AC when there isn’t. No batteries needed.
The pump itself is built from stainless steel and plastic — both food-safe materials commonly used in drinking-water systems. Water potability depends on the well source itself, not the pump — the unit lifts water but provides no treatment, filtration, or purification function. Independent water-quality testing is required to determine drinkability. For potable applications, a downstream sediment filter and UV-treatment stage is the standard configuration.
The Hybsun 3UP1500-125-6E DC solar well pump carries a 2-year manufacturer warranty and is certified to CE (European Conformity, required for sale in the EU including Cyprus) and ISO 9001 (manufacturing quality management system). The DC solar controller carries an IP65 waterproof rating, suitable for outdoor and exposed installations.
