Tech Data for Charge 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. 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 c
an 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.

4.0 Connections
Warning: To be installed and connected by qualified personnel only.
Ensure all power sources are disconnected when making any connections to this unit.
Connect Ground
Using wire of sufficient gauge (min. #16 AWG), connect the PV- and the controller black lead together to the battery negative.
Input = Connect to Battery negative = Black This is a common negative connection
WARNING: To avoid flash or burn injuries, extreme care must be taken when making battery connections. Do not short the battery or output.
Connect Load Battery Positive
Using wire of sufficient gauge (min. #16 AWG), connect the white lead to the BAT + wires, environmentally seal connections if required.
BAT + = white this is the 84.6 V connection
Page 1
LAST CONNECTION: Connect Battery +
Using wire of sufficient gauge (min. #16 AWG), connect the red lead to PV+ wire.
PV + = Red This is the 12 V solar module connection
NOTE: This 72V Controller is sold for use with the Peel and Stick Solar Charging System from Earth Care Solar Technologies, Inc. – Kingsland GA 31548.
