1. INTRODUCTION

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 GP-SB-PWM solar charge controller uses PWM technology and comes in two models: 10A and 30A for 12V systems. Each model features an LCD
user interface that displays various data and enables settings adjustment. This second version of the product comes with major changes such as a
new mechanical and LCD design. The 30A version also comes with an integrated Bluetooth Low Energy module that allows all the data and settings
to be accessible and managed via a mobile app.

1.2 SYSTEM VOLTAGE AND CURRENT

The GP-SB-PWM solar controller is intended for use at 12 VDC nominal system voltage and is rated for a maximum continuous DC input current of
37.5A and input voltage of 35VDC.
Per the National Electric Code (NEC) article 690.7 and 690.8, PV module nameplate ratings at Standard Test Conditions (STC) 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 the 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

The GP-SB-PWM 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).
A custom profile in the settings allows creating a specific battery profile by programming and adjusting various charging parameters such as the
charging voltage set-points.
