Specification It is suitable for the description of the drop of 50mm pipe through the water pipe. The 50 tubes of this generator can be used as a reference for the description. They have all been tested. The drop is based on the vertical drop as the standard, and the length is not used as a reference. 10 meters drop length is 30 meters, but only 10 meters drop, the pipe is 100 meters or 200 meters is useless, because no vertical drop height is used, there is no water pressure impact, the water volume requires a 50 mm pipe through the water pipe to be full, and the height of the drop Different generators have different powers. Taking the 1000-watt micro hydroelectric generator as a reference, the vertical drop of about 3 meters can generate 10 watts to 20 watts, 10 meters can generate 100 watts to 300 watts, 15 meters can generate 300 watts to 500 watts, and 20 meters can generate 500 watts to 500 watts. 700 watts, 30 meters can send 700 watts to 1000 watts, this is based on the vertical drop, not the length. Please follow the instructions for generator installation and use. Connect a drain pipe to the generator water outlet. Try to drain the water as far as possible, connect the pipes around the generator, do not let the water fly around, wrap the leaking place with plastic bags or electrical tape, cover the generator head with something, and put the generator on In the places where the rainwater cannot soak, pay attention to all the wirings to avoid short circuits. The short circuit of water intake is a problem of personal installation and use, and it is not within the scope of after-sales maintenance. Please use strictly according to the instructions. The water pipe is connected to the water outlet and the drain pipe to drain the water farther. You can buy a sewer drain pipe PVC to connect to the water outlet of the generator. The outer diameter of the generator is a bit larger, and it cannot be inserted directly. PVC joints, the plastic joints can be put on by burning the plastic joints a little softly. After putting on, seal the gaps with AB glue. Remember to pay attention to waterproofing of the generator. Package Included 1pc of Generator Because of the light irradiation or computer display difference, please understand we can't guarantee photos and real color is 100% same.
