PowerSpout Pelton - PLT Hydro Turbine

The PowerSpout PLT is a Pelton turbine which on a suitable site 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: 3 to 160 m (10 – 525 feet)
• Dynamic head range: 3 to 130 m (10 – 430 feet)
• Maximum flow per turbine: 8–10 l/s (130 – 160 gpm)
• Minimum flow per turbine: 0.05 l/s (0.8 gpm) at maximum head
• Dimensions: 470 x 400 x 430 mm (18.5 x 15.7 x 17 inches)
• Maximum power: 1200 W standard, 1600 W with the High Power upgrade
• 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 PLT is available as PLT 14/28/40/56/80/170/200/350. The number is the operating voltage — the cable voltage, or MPPV. The open circuit voltage (Voc), which is what you see when nothing is drawing power, can be up to three times higher. A PLT 200 works well with a 200 V grid tied inverter but can approach 600 V when the inverter is not drawing from the turbine, so check your inverter's maximum input voltage against Voc, not against the operating voltage.

A PLT turbine comes with

• 2 jets and 2 valves (2” BSP standard, NPT optional)
• A mid-range oil filled pressure gauge
• 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
• 4 x Tek screw fixing kit
• 4 x spare jet inserts
• Rotor packing set, where we judge it likely to be needed
• 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

• Order the High Power upgrade if your site asks for 0.69 W/rpm or more from each turbine. Our calculator tells you this.
• 2” BSP threaded valves are supplied unless you select NPT threads above.
• A manifold, Camlock hose fittings and other PLT parts can ship in the same carton as your turbine, up to 29 kg total.
• We can approve these turbines up to 2 kW each on sites above 110 m net head, subject to special conditions. Contact your dealer for more information.

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.
