The DC generator is mainly aimed at when the battery power is insufficient and the voltage drops to a safe voltage, the controller of the DC generator starts the motor, and the engine drives the generator to generate electricity — providing power for the air conditioner and charging the battery at the same time. When the voltage of the battery reaches a certain voltage, the controller analyzes the data obtained by sampling the voltage of the battery, and stops the engine. That is to ensure that the battery life is increased to save energy to the greatest extent. The high-temperature and high-power motor enables the product to dissipate heat quickly during use, has a long service life and is durable.Cylinder head fully wrapped design, noise reduction and anti-scaldingThe deluxe version of the muffler reduces the noise generated during use! It is easier to extend the range with low noise.Air inlet, infinite circulation. Waterproof partition double-proof design.No need to install the base, super shock absorption and thick chassis. Rated power 5000W Rated speed 33RPM Rated voltage 48/60/72V Maximum current 65/55A Fuel consumption 380G/M.H Starting method permanent magnet motor Ignition method magnetic replacement Air filter foam filter Maximum torque 13/2500 Calibration power 5000/4500 Compression ratio 8.5:1 Displacement 212ML Size 36x30x38CM Weight about 23KG Note: Due to the different production batches, the appearance of the exhaust pipe will be slightly different, and does not affect the normal use of the machine. Start and stop Manual button start, press the switch to the start gear, hear the machine start to release.Under-voltage automatic start, the switch to the middle gear, low voltage automatic start (when lower than the rated voltage of about 5V). Range extender maintenance and routine maintenance New machine using the first break-in period, the first use of 5 hours to replace the oil, the second 10 hours to replace the oil, clean the air filter sponge once (open the air filter housing to take out the sponge with a hair dryer to blow clean), the later 100 hours to replace the oil, clean the air filter sponge once.When running for a long time, pay attention to check (the amount of oil, fuel) is not enough to add in time, the machine is not used for a long time, shut down before the tank switch (horizontal for off), burn out the carburetor oil accumulation automatically shut down, remove the positive and negative battery line to avoid the loss of battery power for the next use. Installation precautions After installing the range extender, the distance around it should be not less than 15mm.The exhaust port should be tilted downward, not allowing the exhaust port to be aligned with the operating position, not allowing the exhaust port to be aligned with the electrical parts.The cylinder head should be in the windward position as far as possible to ensure the cooling effect of the range extender.Not allowed to be used in a closed environment.Wires, connecting cables, etc. should be fixed Start and stop. Note: Due to the different production batches, the appearance of the exhaust pipe will be slightly different, and does not affect the normal use of the machine.The product is very heavy, even if we pack the product very safely, there may encounter violent transportation resulting in parts damage, when you receive the package, if you find that the fuel tank / base or filter and other transportable parts are damaged, we can resend the damaged parts to you.When you open the package, you may smell the smell of gasoline, please do not worry, this is normal, because the product needs to go through a whole set of tests before leaving the factory to make sure it can work normally.If you need, we can provide installation videos and instructions in English.
