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

all at a fraction of the cost of competitors products.
