Earth Care Solar Golf Cart Controllers
1)The job of an MPPT charge controller is to make sure the power output is constantly being regulated and calculated every time the voltage of the input changes in the slightest. This characteristic is desirable if the input voltage is constantly changing.
2) Our controller is custom built to maximize the power output when given as input the Vpmax of our breakthrough Peel & Stick Solar modules. That means that when the first light hits our panels, our controller begins converting all available power to a suitable voltage and current to properly regulate your Golf Cart batteries. When you turn the key to your cart, you know that our controller is providing almost 100% of the power produced by the solar module directly to your batteries.
3) This technique is much more cost effective because we specify exactly what voltage the controller will receive from the panels. PowerFilm Engineers from the solar manufacturing facility, Engineers responsible for building our charge controllers, and independent Engineers in the field have all confirmed the efficiencies and can assure maximum productivity.
4) Our system is less complicated, built on sound analog technology, allowing for the omission of expensive microprocessors, and built with fewer parts…fewer parts that can be damaged or might fail over time.
5) Unlike fancy microprocessor controlled chargers, our controller will not be damaged by a lightning strike. We specify the exact inputs to the charge controller, hard wire those values using proven analog circuitry, and obtain high efficiencies at a savings to the end customer. We do not believe in over engineering or providing more than you need, simply for our profit. While others boast enormous panels, we strive to supply exactly what you need. It is our goal deliver a proven system that will add value and convenience to your Golf Cart for years to come, and do this
ll at a fraction of the cost of competitors products.
