1.0 Solar Controller Overview
1.1 Introduction
A Solar Controller (or Charge Controller / Regulator) is an essential component
of your photovoltaic solar system. The Controller maintains the life of the battery
by protecting it from overcharging. When your battery has reached a 100% state
of charge, the Controller prevents overcharging by limiting the current flowing into
the batteries from your solar array.
The solar controller used in the DURALITE-100 kit features an LCD digital
display that shows the charge current of the solar array, system battery voltage
and battery state of charge.
1.2 System Voltage and Current
This controller is intended for use at 12 VDC system voltage and is rated for a
maximum continuous DC input current of 37.5A and input voltage of 35VDC.
Per National Electrical Code (NEC) article 690.7 and 690.8, PV module
nameplate ratings must be multiplied by required values (typically 1.25 for both
voltage and current) to obtain the maximum voltage and continuous current
available from the module.
Applying NEC factors, the maximum allowable nameplate PV Panel rated Isc is
30A (30A x 1.25 = 37.5A), and the maximum voltage, Voc is 28VDC (28VDC x
1.25 = 35VDC).
The voltage and current ratings of all equipment connected to PV panels must be
capable of accepting the voltage and current levels available from PV panels
installed in the field.
1.3 Battery Type
This solar controller is suitable for use with lead acid batteries (vented, GEL, or
AGM* type) as well as some lithium iron phosphate (LiFePO4) batteries that are
supplied with a Battery Management System (BMS).
*Use the Sealed battery profile for AGM

2.0 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INSTRUCTIONS FOR THE
DURALITE KIT AND SOLAR CONTROLLER THAT SHOULD BE
FOLLOWED DURING KIT USE AND MAINTENANCE.
•Read this manual in its entirety before using the DuraLite kit for
the first time.
•DO NOT GET WET. Bring in the DuraLite kit when it rains.
•Use only with approved DuraLite connections and harnessing.

SOLAR CONTROLLER

•Please cut off all connections of the PV array, fuses or breakers
which close to the battery before the controller installation and
adjustment.
•Power connections should remain tight to avoid excessive
overheating
•No user serviceable component inside the controller. DO NOT
disassemble or attempt to repair the controller.
Disconnect all
power sources
Electricity can be very dangerous. Installation
should be performed only by a licensed
electrician or qualified personnel.
Battery and wiring
safety
Observe all safety precautions of the battery
manufacturer when handling or working
around batteries. When charging, batteries
produce hydrogen gas, which is highly
explosive.
Wiring connections
Ensure all connections are tight and secure.
Loose connections may generate sparks and
heat. Be sure to check connections one week
after installation to ensure they are still tight.
Work safely
Wear protective eyewear and appropriate
clothing during installation. Use extreme
caution when working with electricity and
when handling and working around batteries.
Observe correct
polarity
Reverse polarity of the Battery 1 terminals will
cause the controller to give a warning tone.
Reverse connection of Battery 2 terminals will
not cause an alarm. However, the controller
will not charge or display information for
Battery 2 on the LCD. The controller will not
function unless Battery 1 terminals are
connected to a battery with proper polarity.
Failure to correct this fault could damage the
controller.
Do not exceed the
SOLAR
CONTROLLER max
current ratings
The maximum current of the solar system is
the sum of parallel-connected PV module–
rated short circuit Currents (Isc) multiplied by
1.25. The resulting system current is not to
exceed 37.5A. If your solar system exceeds
this value, contact your dealer for a suitable
controller alternative.
Do not exceed max
voltage ratings
The maximum voltage of the array is the sum
of the PV module–rated open-circuit voltage of
the series connected modules multiplied by
1.25 (or by a value from NEC 690.7 provided
in Table 690.7 A). The resulting voltage is not
to exceed 35V. If your solar system exceeds
this value, contact your dealer for a suitable
controller alternative.

3.0 Choosing a Battery
The SOLAR CONTROLLER is suitable for use with lead acid batteries (vented,
GEL, or AGM type) as well as some lithium iron phosphate (LiFePO4) batteries
that are supplied with a Battery Management System (BMS). If using lithium ion,
it must be lithium iron phosphate (LiFePO4) chemistry with a BMS. No other
chemistries are compatible.
Lithium batteries typically have maximum allowed charge currents. These
maximums typically decrease in cold temperatures. SOLAR CONTROLLER does
not limit current for these restrictions, and system design of the solar array must
account for this.
Be sure to follow all battery manufacturer safety instructions.
4.0 DuraLite Kit Wiring Diagram
The SOLAR CONTROLLER Maximum 37.5A rating is based on a 30-amp total
maximum short circuit current rating (Isc) from the solar modules nameplate
ratings. The National Electric Code specifies the PV equipment/system rating to
be 125% of the maximum Isc from the PV module ratings (1.25 times 30 =
37.5A). E.G. Three modules in parallel with an Isc of 7 amps each equal a total
Isc input of 21 amps. When selecting PV modules for use with the SOLAR
CONTROLLER do not exceed a total nameplate Isc current of 30A. Solar
modules list the Isc amps on their nameplate label.
The controller will not work unless there is a battery connected
to the Battery 1 terminals.
WARNING: When the photovoltaic (solar) array is exposed to light, it
supplies a dc voltage to this equipment.
