Capacitor Units Save Money on Your Electric Bill!
How does it work?
When a motor in your home starts, it asks your utility company's transformer for power. The demand of electricity from your motor runs through the wiring in your home to the panel box traveling to your meter, finally reaching its destination of the transformer and back down to your home again. Throughout this process, the lines/wiring heats up and strains the motor and wiring. The heat generated is called watts.
During a normal electrical process there is lost energy that you are being billed for by your utility company, but are not able to use. The capacitor stores (otherwise lost energy/watts) and releases energy to your motor when needed to function properly. This reduces the amount of heat on the wires and the motors in your home or business. Reducing this heat will lower your electricity bill and increase the life of your motors.
Inductive Motors are in your refrigerator, freezer, washer, dryer, ceiling fans, elevators, air conditioning units, etc. If you use the old T-12 Fluorescent Lighting, the ballast is also an inductive load. Anything with a copper winding that creates an electromagnetic field is an inductive load, just like your inverter that turns DC current into AC current. Using methods from large industrial complexes, capacitor reclaims wasted energy and recycles electrical energy. It protects against power surges and increases the capacity to your electrical panel by causing it to run cooler. By doing so, this saves you money

How We Know it Works?
It is an inductive load for your power company, just like the motors in your home (A/C, refrigerators, etc.), this is your power company's inductive loads, and these are the capacitors your power company uses to correct their power factors. When you correct the power factor, it reduces demand. The electric meter that your electric company reads is a demand meter. With the proper use of capacitors you can reduce demand and legally slow down your meter; your electric company has been using this very same technology for 70+ years to correct their power factors. Now why would your power company spend tens of thousands of dollars on a capacitor bank to correct their power factor if it doesn't work?
It Does Work!
If you look around your neighborhood on the power poles, for about every 50 transformers, you will notice 1 of these banks of capacitors correcting the power factors of the transformers in your neighborhood.
How Many Capacitors Do I Need?
Usually a home needs 1 unit; for a business, it depends on the amount of panels -- capacitors work up to 200, 400, 600, 800, and 1000 amps. If you are unsure, check your panel box. If your main breaker is 200 amps or less, you will need only 1 unit.
Electric power has two components:
Total power is measured in KVA (1000 Volts-Amperes). The ratio of working power to total power is called Power Factor. The function of Power Factor Correction Capacitors is to increase the power factor by supplying the reactive power when installed at or near inductive electrical equipment.
