1. SOLAR CONTROLLER OVERVIEW

1.1 INTRODUCTION

A Solar Controller (or Charge Controller / Regulator) is an essential component of your photovoltaic solar system. The Controller main-
tains 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
