What It Is
The Hybsun 3UP750-60-6C DC solar well pump is a submersible borehole pump that runs directly from your solar panels — no grid hookup, no diesel generator, no inverter. It uses a brushless DC motor coupled to a multi-stage plastic impeller assembly inside a stainless steel pump body. The whole system is just three parts: the pump (lowered into your well), the DC solar controller (mounted above ground), and your PV array. Sunshine in, water out.
Motor Technology
DC Brushless permanent-magnet synchronous motor
Inside the Hybsun 3UP750-60-6C 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 motor uses NSK bearings (a Japanese industrial bearing brand), paired with an alloy mechanical seal — both chosen so the pump handles long daily run-times under continuous submersible duty. A double water seal keeps the pump fully waterproof and leak-proof.
Every Hybsun 3UP pump ships with its matched DC solar controller — an IP65 waterproof box that sits between your solar panels and the pump. It tracks the maximum power point of your PV array (MPPT) to pull the most power available, handles up to 15 A on the input side, and shows live power, voltage, current and motor speed on a built-in LED display.
One feature unique to the 3UP DC controller: it has an automatic charging function that lets you optionally connect a battery. The controller charges the battery during the day while running the pump, and at night the battery can keep the pump working — useful if you need water at non-solar hours (livestock drinking, evening irrigation, household use). The battery is an optional add-on, not required for normal solar operation.
The Hybsun 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
The Hybsun UP DC submersible solar well pump kit is in a wooden box with the pump, the DC solar controller, and accessories. Here’s an unboxing walkthrough showing what’s in the box and how the kit goes together:

Who Should Buy This
The Hybsun 3UP750-60-6C DC solar well pump is sized for shallow-to-medium wells (up to ~60 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:
All Hybsun solar well pumps share the same stainless-steel construction, NSK bearings, MPPT controller and submersible design — they differ on power, head capacity, flow rate and whether they have grid AC backup. Compare across the range:
Hybsun’s rule for sizing the PV array is straightforward: panels should add up to at least 1.3 × the pump’s rated power. For the Hybsun 3UP750-60-6C DC solar well pump that means at least 975 Wp of solar panels (3 panels depending on individual panel wattage). The 30% extra covers the everyday losses that pull solar panels below their nameplate rating in real conditions — heat de-rating, dust, cable losses, panel ageing over time — so the pump runs at its full flow rate across the productive solar window, not just for a couple of hours around noon.
The Hybsun 3UP750-60-6C DC solar well pump accepts a PV string running at 72-144 V Vmp, with open-circuit voltage staying <160 V. That range is wide enough to handle the temperature swings and partial shading of a typical Cyprus day without the controller losing its MPPT lock — so the pump runs smoothly from morning through evening, not just at peak sun.
The honest answer depends entirely on how deep you have to lift the water. Like all submersible well pumps, the Hybsun 3UP750-60-6C DC solar well pump’s flow rate drops as the lift height (total dynamic head) increases. The headline 6 m³/h figure is what the pump produces at zero head — drop the pump into a real well and the flow drops proportionally.
Here’s what the manufacturer’s performance curve actually shows for the Hybsun 3UP750-60-6C DC solar well pump, with corresponding daily output assuming a typical 6-hour useful solar day in Cyprus summer:
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 5-10m on top of the static depth. The manufacturer’s spec table lists H.Max as 60m, but the curve shows the practical working range tops out around 40-48m.
To translate flow rate into your specific water demand:
If your borehole sits deeper than ~30m static water level (so total dynamic head is approaching 40m or more), the Hybsun 3UP1500-125/6E is a substantially better choice. Both pumps have the same 6 m³/h max flow on paper, but their performance curves are completely different — at 40m head, the 3UP1500 delivers ~4.8 m³/h (vs the 3UP750’s ~1.0 m³/h). That’s nearly 5× more water at the same depth.
For an exact sizing calculation for your specific borehole, send CGP Solar your static water level, expected drawdown, pipe run length and storage tank height — we’ll run the head calculation and pick the right pump from the Hybsun range.
The Hybsun 3UP750-60-6C 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 resists corrosion from minerals in well water; plastic internals (impellers, diffuser stages) handle abrasive sand and grit without metal-on-metal wear. The Hybsun datasheet calls out the design as a “stainless steel oil cylinder” plus plastic impeller — purpose-built for submersible duty.
The Hybsun 3UP750-60-6C DC solar well pump uses NSK bearings — a Japanese industrial bearing brand favoured by manufacturers worldwide for continuous-duty rotating equipment. Combined with an alloy mechanical seal and a double water seal, the pump is built to handle the long daily run-times of well-pumping duty. Hybsun specifically mentions “offering the longer working life” in the manufacturer datasheet — important when the pump lives 30-100+ metres down a borehole.
The controller has a soft-start feature that brings the motor up to speed gradually rather than slamming it on at full power. That avoids the inrush-current spike that wears out brushed and AC motors over thousands of start/stop cycles — and it’s one of the reasons Hybsun offers a 2-year warranty on a pump that may run every day all year.
If the well runs dry (which can happen during peak summer drawdown), the pump stops automatically and tries again 30 minutes later. No manual reset, no burned-out motor from dry running. Particularly useful for wells with variable water levels through the season.
One unusual feature of the 3UP DC controller: it has an automatic charging function that lets you optionally connect a battery. The controller charges the battery during solar hours while running the pump, and at night the battery can keep the pump working — useful when you need water at non-solar hours. It’s an optional add-on (not required), but a worthwhile upgrade for livestock watering or evening household use.
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 (1-2 days), 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 60 metres, but that’s the theoretical shutoff head where flow drops to zero. Looking at the actual performance curve, the practical working range tops out around 40-48 metres total dynamic head — beyond that, flow drops to almost nothing. Within the useful range: at 10m head you get ~5 m³/h flow, at 20m ~3.6 m³/h, at 30m ~2.4 m³/h, at 40m ~1.0 m³/h. The 3UP750 is the right choice for shallow-to-medium Cyprus wells with a static water level around 15-30 metres (giving a total dynamic head of roughly 20-40m once pipe friction is added). For deeper boreholes, the Hybsun 3UP1500 maintains useful flow up to 100+ metres of head.
Hybsun specifies PV panel power of at least 1.3 × pump power, so the Hybsun 3UP750-60-6C DC solar well pump needs at least 975 Wp of solar panels (3 panels depending on panel wattage). The PV string voltage also has to land within the controller’s MPPT range: 72-144 V Vmp, with open-circuit voltage <160 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. You can optionally connect a battery; the controller charges it during the day while running the pump, and at night the battery can keep the pump working. This is genuinely useful for livestock watering (animals drink in the evening too) or household water supply where you want flow available 24 hours. The battery is an optional add-on, not required — the pump runs perfectly well on solar alone during daylight hours.
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. Whether the water it pumps is potable depends entirely on the quality of your well water (which should be tested independently) — the pump doesn’t treat or purify the water, it just lifts it. For drinking water you’ll typically want a filtration or UV-treatment system downstream.
The Hybsun 3UP750-60-6C 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.
