PowerSpout Low Head - LH Hydro Turbine

The PowerSpout LH is a highly efficient propeller turbine for sites with plenty of water and very little fall. On a suitable site it can produce up to 1.6 kW, 24 hours a day, all year. If you need more, units can be stacked to generate over 16 kW on the same penstock and power cable.

Specifications

• Static head range: 1 to 5 m (3 – 16 feet)
• Maximum flow per turbine: 55 l/s (880 gpm)
• Minimum flow per turbine: 25 l/s (400 gpm)
• Dimensions: 300 mm diameter x 1050 mm long (12 x 42 inches)
• Maximum power: 1600 W
• Maximum short circuit current (Isc): 30 A, set by the MC4 connectors. An upgrade to 50 A is available where your site needs it — our calculator works this out from your figures.

Voltage

The LH is available as LH150/250/400. Note that unlike our PLT and TRG turbines, the number here is the maximum runaway voltage (Voc) — not the operating voltage. The best operating voltage, the cable voltage or MPPV, is about half of it. An LH400 works best at 200 V and should never exceed 400 V. Each turbine is built for your site, and the voltage depends on your head.

An LH turbine comes with

• Leaf cutter bar on the propeller
• 1 x PVC base fitting for a 200 mm OD PVC draft tube (the draft tube itself is not supplied)
• Manual grease fitting
• One SKF LAGD 125/WA2 automatic greaser, fitted — over 12 months of continuous lubrication
• Bearing block pre-charged with 70 g of SKF LGWA 2/0.4 grease, to keep moisture out from day one
• 2 m of 4 mm² tinned PV wire for +, − and earth
• 2 x MC4 cable connectors
• 3 year warranty on standard turbines (under 1200 W), 2 years above 1200 W

Bearings. Replace the automatic greaser once a year and your bearing warranty runs for the full term of the turbine warranty. Replacement greasers and grease tubes are available here.

Ordering

• On heads above 3.6 m you must order the High Power version and use a 250 mm OD draft tube, which needs this adaptor.
• Below that head, order the High Power upgrade if your site asks for 0.69 W/rpm or more from each turbine. Our calculator tells you this.
• Other LH parts can ship in the same carton as your turbine, up to 29 kg total.

Every PowerSpout turbine is built to match your site, so you will need your site data and a completed calculation before ordering. If you are new to this, start with our getting started guide. We sell direct to competent DIY customers, but system design and installation support is a paid service. Buying through a dealer is often cheaper: they can advise on the best combination of products, keep freight costs down, and help you avoid expensive mistakes.
