Page 2: Read This First
READ THIS FIRST This manual contains important information concerning your new PowerPal T2 Turgo micro-hydroelectric generator. It covers Model MHG-T2. You should read this manual carefully before installing PowerPal or allow a trained technician from your local PowerPal Service Center to install it for you. Your PowerPal generator is designed to be simple to operate and easy to maintain. -

Page 5: Selecting A Site
SELECTING A SITE PowerPal is designed for use in a wide range of locations. There are two critical factors that influence power output – head and flow. Head is the vertical distance between the turbine and the water source (forebay), measured in meters. Flow is the amount of water that passes through the turbine at any instant, measured in litres per second (l/sec). -
Page 6: Site Preparation
Measuring Flow The best way to measure the water flow is to take a piece of pipe the same diameter as the penstock, insert it in the stream or dam where the flow is expected to come from, and measure the flow from there. In the diagram below, a short length of pipe (less than 1 meter) is buried into the side of a small ‘dam’... - Page 7 The penstock is shown by the black line A-B. In the first diagram (A) the penstock follows the stream. This may lead to unnecessary length and cost. In diagram B, the most direct route is selected to reduce length and cost. Diagram C shows the best alternative where a side channel or ‘power conduit’...

Page 8: System Installation
SYSTEM INSTALLATION Mechanical Aspects After locating a suitable site and completing the civil works, your PowerPal is ready for installation. To do this: 1. Bolt the turbine to a turbine stand or base which allows at least 300mm clearance between the turbine and the ground. This clearance is required to prevent splashback that will disrupt turbine performance. - Page 9 hydro Main network or house 220VAC turbine distribution board house supply Electronic Load Ballast load Controller - ELC To connect the electrical components, please follow these steps: The electrics should be installed by persons competent in mains voltage wiring. This system operates on a switched neutral basis. Neutral and phase connections to the load elements should be treated as live at all times! 1.

4. Connect the user load cables L1 and L2 between the control box and the house. 5. Connect the ballast load (C) to the control box and user load cable. The ballast load is rated 10-15% (maximum) higher than the rated power output of the generator e.g. -

5. Operate like this for 15 minutes while observing any unusual noise, excessive temperature or other problems and if OK then switch on the power to the user. Up till now the ballast load has been receiving all the power and should be hot, but once switching on the user load the power to the ballast load will fall. - Page 12 Changing the Bearings and Seal Apart from greasing the bearing, there are only two tasks that must be completed at regular intervals. These are the changing of the lower generator bearing & turbine bearing and the lower bearing seal every two years. See the section on Technical Specifications at the end of this manual for part numbers.

Page 13: Troubleshooting
TROUBLESHOOTING If any problems are encountered, check this section before contacting your Service Center. 1. Head and flow conditions appear to be OK, but PowerPal will not work. It is likely that the system has been installed incorrectly. Check this by following the steps once more. - Page 14 2. PowerPal has provided electricity for a while and suddenly the electricity stops. If this instruction manual is not followed and power consumption is too high, or if there is a short circuit in an appliance the circuit breaker in the electronic load controller will trip.

a) Start the generator and adjust the spear valve to obtain 220-240 volts, 0 amps at the panel. [Do not turn the circuit breaker on]. b) Adjust the potentiometer on the circuit board very slowly to the left. When you detect a small decrease in voltage, stop. -
Page 16: Appendix A - Forebay Design
APPENDIX A – FOREBAY DESIGN The instructions given on page 7 of this manual to design the forebay are adequate for most cases. The most important aspects of forebay design are: 1) To allow a continual flow of water to the penstock so that the turbine keeps functioning. - Page 17 POWERPAL T2 TURGO MODELS T-2 Model (1.5kW) (single nozzle) Output (watts) H (head, in metres) Q (flowrate, in l/sec) 18.5 17.3 16.2 15.2 14.4 13.6 12.9 1250 18.5 17.3 16.3 15.4 14.6 13.9 1361 18.5 17.4 16.5 15.6 14.8 1452 18.5 17.5 16.6 15.7 1543 18.5 17.5 16.6...
