What It Is
Hybsun SSP900-19-21C DC solar pool pump 900 W for typical residential pools
The Hybsun SSP900-19-21C DC solar pool pump is the sweet spot of the SSP DC range. At 900 W it has the power to circulate a typical residential pool comfortably within recommended turnover times, without the larger PV array commitment of the 1200 W model. The pump uses a DC brushless permanent-magnet synchronous motor designed for high speed and high efficiency from solar PV, paired with a DC solar controller that handles MPPT tracking, auto start/stop and fault protection.
The pump runs directly from your solar panels — no grid hookup, no electricity meter, no inverter. The full Hybsun SSP DC system is just three parts: the pump, its DC solar controller (included in the box), and your solar panels.
Motor Technology
DC Brushless permanent-magnet synchronous motor
The Hybsun SSP900-19-21C DC solar pool pump is built around a DC brushless permanent-magnet synchronous motor — designed to run at high speed and high efficiency from a solar PV array. The motor uses NSK bearings (a premium Japanese bearing brand) paired with an alloy mechanical seal, both chosen for longer working life under the continuous-duty conditions of pool circulation. The pump body is sealed with a double water seal for waterproof and leak-proof operation.
What the included DC solar controller does
Every Hybsun SSP900-19-21C DC solar pool pump ships with a dedicated DC solar controller — an IP65-rated waterproof box that sits between your solar panels and the pump. It tracks the maximum power point of your solar array (MPPT) to extract the most power possible, accepts up to 15 A maximum input current, and shows live power, voltage, current and motor speed on an LED display. It can adjust pump speed automatically based on available sunlight, or you can set the speed manually.
Built-in protection
Soft start (no inrush current damage to the motor), dry-run protection (pump stops if there’s no water, auto-restarts 30 minutes later), over-voltage, under-voltage, over-current, high-temperature, and adjustable speed (frequency conversion). The controller automatically starts and stops the pump based on solar conditions.

Who This Is For
Is the Hybsun SSP900-19-21C DC solar pool pump the right pump for you?
The Hybsun SSP900-19-21C DC solar pool pump is sized for typical residential pools (typically 40–75 m³). The most common residential pool size in Cyprus — single-family homes with a standard 6×3 m, 8×4 m or 10×4 m pool. A 900 W SSP900 will typically complete one full turnover in 3–5 hours, so a 6–8 hour solar day easily covers two complete circulation cycles.
The buyer profiles below cover the most common situations where this exact pump is the right fit:
Typical Cyprus family villa
Residential pools roughly 40–75 m³ — the most common Cyprus pool size. A 1.0 kW AC pump running 7 hours daily for the swim season is the typical load this pump replaces.
Families who use the pool every day
Daily summer use means daily pool filtration costs. Replacing that load with solar circulation is the single biggest swimming-pool savings most Cyprus homeowners can make.
EAC bill-shock victims
If your summer electricity bill jumps by €60–€100/month vs winter, your pool pump is a major part of that. The Hybsun SSP900-19-21C DC solar pool pump removes it.
AC pool pump replacement projects
If your existing 0.75–1.0 kW AC pump is reaching end of life, replacing it with the Hybsun SSP900-19-21C DC solar pool pump instead of another AC pump is the obvious upgrade.
If you’re not sure whether the Hybsun SSP900-19-21C DC solar pool pump is the right size for your pool, the simplest test is to talk to us with your pool dimensions and existing plumbing layout — CGP Solar will recommend the right model from the SSP DC range. The four models share the same 2″×2″ plumbing, motor platform and DC controller architecture, so you can compare them on flow and head specs alone:
Hybsun SSP500 — 500 W · 17 m³/h · smaller pools
Hybsun SSP900 (this pump) — 900 W · 21 m³/h · typical residential
Hybsun SSP1200 (72 V) — 1200 W · 31 m³/h · large pools
Hybsun SSP1200-D (96 V) — 1200 W · 31 m³/h · for 96 V PV strings
Hybsun SSP-H900 AC DC hybrid — 900 W · 21 m³/h · solar + grid AC backup for typical pools
Hybsun SSP-H1200 AC DC hybrid — 1200 W · 31 m³/h · solar + grid AC backup for for large pools
How many solar panels do you need for the Hybsun SSP900-19-21C DC solar pool pump?
Hybsun’s rule for sizing the solar array is simple: your solar panel array should be at least 1.3× the pump’s rated power. For the Hybsun SSP900-19-21C DC solar pool pump that means at least 1170 Wp of solar panels (3–4 panels depending on panel wattage). That extra 30% covers real-world losses — clouds, hot panels, cable resistance, panel aging over time — so the pump reaches its full flow rate throughout the day, not just at solar noon.
PV string voltage range
The Hybsun SSP900-19-21C DC solar pool pump accepts a PV string running at 72–144 V Vmp with up to < 160 V open-circuit. That range is wide enough to handle temperature swings and partial shading without the controller dropping out of MPPT — so the pump keeps running smoothly through the whole day, not just at peak sun. The C-suffix means the 72 V version — designed for standard residential PV string configurations (typically 2 panels in series at Vmp).
How long will the Hybsun SSP900-19-21C DC solar pool pump take to circulate a pool?
Pool turnover is the time it takes to push your entire pool’s volume of water through the filter once. It’s the standard way pool pumps are sized — most pool service guidelines recommend at least one full turnover every 6–8 hours. The table below shows approximate turnover times for the Hybsun SSP900-19-21C DC solar pool pump at a realistic operating flow rate (allowing for typical 5–8 m head losses from pipes, fittings and filter):
|
Pool volume
|
Approx. turnover time
|
Per solar day (6–8 h)
|
|---|---|---|
|
30 m³ (small backyard)
|
~2.0 h
|
~3.0 to ~4.0 full turnovers
|
|
50 m³ (typical residential)
|
~3.3 h
|
~1.8 to ~2.4 full turnovers
|
|
75 m³ (large residential)
|
~5.0 h
|
~1.2 to ~1.6 full turnovers
|
|
100 m³ (villa / small hotel)
|
~6.7 h
|
~0.9 to ~1.2 full turnovers
|
Realistic operating flow rates allow for 5–8 m of typical system head losses. Manufacturer’s stated maximum of 21 m³/h is the zero-head free-flow figure; actual flow under real system head is lower. For a precise sizing calculation contact CGP Solar with your pool dimensions, plumbing layout and filter type.
What makes the Hybsun SSP900-19-21C DC solar pool pump different from a generic solar pool pump
NSK bearings · alloy mechanical seal · double water seal
The Hybsun SSP900-19-21C DC solar pool pump uses NSK bearings — a Japanese bearing brand chosen by manufacturers worldwide for industrial duty applications. Combined with an alloy mechanical seal and a double water seal design, the pump is built for the continuous-duty conditions of pool circulation. Hybsun specifically calls out “offering the longer working life” in the manufacturer datasheet.
Soft start — protects the motor
The DC controller uses a soft-start function that ramps the motor up gradually instead of slamming it on at full power. This avoids the inrush-current spike that wears out brushed and AC motors over time, and is one reason the manufacturer can offer a 2-year warranty on a continuous-duty pool pump.
Adjustable speed — automatic or manual
The controller’s frequency conversion function automatically adjusts pump speed to track available solar power throughout the day, so the pump keeps running at the highest speed the panels can support. You can also override the automatic mode and set the speed manually if needed.
2″ × 2″ connections — drops onto your existing pool plumbing
The 2″ suction and discharge connections are the standard size for residential pool plumbing in Cyprus. That means the Hybsun SSP900 drops straight onto your existing pool plumbing — no adapter fittings, no re-plumbing. Same footprint as conventional AC pool pumps; you literally just swap the old pump for the new one.
Why this beats grid-powered pool pumps in Cyprus
Electricity in Cyprus is among the most expensive in Europe — currently around €0.32 per kWh for residential customers per the Electricity Authority of Cyprus — and pool filtration is a constant heavy load. The Hybsun SSP900-19-21C DC solar pool pump removes that bill entirely. The pump runs when the sun shines, which is exactly when pools most need circulation: algae growth, evaporation and bather activity all peak in daylight hours.

FAQ’s
Most asked questions
about Hybsun SSP900-19-21C DC solar pool pump
No — the pump runs directly from your solar panels through the included DC controller. It starts automatically when there’s enough sunlight and stops when there isn’t. For most pools this works out perfectly: algae growth, evaporation and chlorine demand all peak in the daytime, which is exactly when the pump runs. If you need guaranteed pump operation at night or in any weather, look at our Hybsun SSP-H900 Hybrid AC/DC pool pump instead (same 900 W power level as the SSP900, but with grid backup) — it runs from solar when there’s sun and switches to grid power when there isn’t.
Hybsun specifies PV panel power ≥ 1.3 × pump power, so the Hybsun SSP900-19-21C DC solar pool pump needs at least 1170 Wp of solar panels (3–4 panels depending on panel wattage). The voltage of the PV string must fall within the controller’s MPPT range: 72–144 V Vmp with open-circuit voltage below 160 V. CGP Solar designs the exact PV configuration during the quotation stage.
Yes, in most cases. The 2″ × 2″ inlet/outlet matches standard residential pool plumbing in Cyprus, so the Hybsun SSP900-19-21C DC solar pool pump drops into the same plumbing footprint as conventional AC pool pumps. The difference is power source — the Hybsun SSP900-19-21C DC solar pool pump needs a sized PV array and the included DC controller instead of a 230 V AC supply. CGP Solar handles the changeover including any plumbing adapters and PV array sizing.
The Hybsun SSP900-19-21C DC solar pool pump only runs when there’s enough sunlight to power it directly — that’s by design, so you get free pool circulation without an electricity bill. For most Cyprus residential pools that’s plenty: a typical daytime run-time of 6–8 hours easily covers a full pool turnover. If you do need pump operation at night, on heavily overcast days, or guaranteed circulation regardless of weather, look at our Hybsun SSP-H900 Hybrid AC/DC pool pump — same 900 W power as the SSP900, but it runs from solar in the day and switches to grid AC automatically when there isn’t enough sun.
