The voltage coming out of my 40 VDC Ametek generator goes higher than 40 VDC at high winds, will this burn up the charger, or blow a fuse, or can it compensate?
A too high voltage can burn off the charger and I had such an experience. About two years ago, my TV was damaged because of too high voltage. As I had a ten-year guarantee on it, I decided to ask for help from the company where I bought my TV from. They said that it is not their failure because the TV was damaged because of a too high voltage, and it could be caused by the electricity disconnection and reconnection. I was so annoyed. It was horrible. Later, I stumbled on a site and found out that there are Voltage Stabilizers that automatically control the output voltage. I bought such a device and I don’t have to worry anymore regarding the safety of my devices.
A. What is happening is the motor is very capable of reaching well over 100 volts DC. This is normal. When you hook it to a battery the battery will control the voltage level like a regulator. Meaning if your battery is at 11.0 volts when you hook it up, the open voltage from the generator will drop to 11.0.. As it charges it will rise 11.1, 11.2, 11.3, etc until the battery reaches full charge. Once the battery is at full charge is when a charge controller comes in… At that point the charge controller will kick in protect your battery from over charging. The higher the open volts that the generator has the potential to produce the higher the charge rate, or amperage will be.
