Type of a battery charge regulator where the charging current is controlled by a switch or transistor connected in parallel with the PV panel. Overcharging of the battery is prevented by shorting the PV output. Shunt regulators are common in PV systems as they are relatively cheap to build and simple to design. Series regulators usually have better control and charge characteristics.
A bypass device for power not needed for charging batteries. When batteries are full, the regulator shunts all or part of the excess power to a Dump Load to protect the batteries from overcharging damage.
a small electronic component that clamps a power supply voltage at a fixed level
A type of linear power supply where a transistor or active control element is used in parallel with a load.
An electrical device that begins conducting at a specified volt age and conducts as much current as required to hold its terminal volt age to that specified volt age. The power supply is designed to only supply a maximum amount of current that is within the safe operating capability of the volt age reference (i.e. the shunt regulating device).
A device to transfer power when batteries are fully charged, the regulator shunts all or part of the excess power to a Dump Load to protect the batteries from overcharging. Sigh-gone ;) That sudden breath of air from your lungs when you step back and look at your generator on the pole, also known as a “sigh of relief”. The airflow from your lungs causes a sudden atmospheric change around your property that will leave you without any wind for several days. I made this up as the only logical conclusion for why we never have any wind for a couple of days after completion. If you have a better theory let me know! ;)
