28 Amp Digital PWM Charge Controller
With Pulse Width Modulation (PWM) technology this charge controller helps to maintain a higher
charging efficiency, thus maintaining a higher battery reserve and capacity than the standard on-off 8
Amp charge controller. The 28 Amp Digital PWM Charge Controller features a digital LCD display and
adjustable voltage settings.

Selecting the Correct Charge Controller
Charge Controllers may be sold separately and are required for installations of solar systems arrays
that are rated 12 Watts and higher. Charge Controllers help to protect the battery(s) and solar panel(s)
from harmful reverse currents, battery over charging and high wattage surges, addition protections are
found on larger charge controllers.
If two or more solar panels are connected in series/parallel make sure that the sum of the short circuit
current ratings of all panel strings does not exceed 80% of the charge controller's current rating i.e. 8
Amps or 28 Amps.
8 Amp Charge Controller
is an easy to connect and easy to read charge controller with LED light indictors for battery charging
cut-in voltage 13V and battery full cut out voltage 14.2V. The 8 Amp Charge Controller is compatible
with solar system arrays rated up to 130 Watts.

Connecting an Inverter
An inverter can be used to converting the 12 Volt energy created to 120 Volt Electricity.
Inverter sizes and types vary depending on your power consumptions needs. Please discuss which
inverter to purchase with your Inverter dealer.
