1.0 Installation 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 GP-PWM-30-UL uses Pulse Width Modulation (PWM) technology
and a unique four stage charging system that includes an optional
equalize setting to charge and protect your battery bank. The GP-PWM-
30-UL features an LCD digital display that shows the charge current of
the solar array, system battery voltage and battery state of charge. The
GP-PWM-30-UL also features Maximum Power Boost Technology™ for
manual bulk and absorption charge at any stage of the charge cycle.
1.2 System Voltage and Current
The GP-PWM-30-UL 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 the National Electric 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 true 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-PWM-30-UL is suitable for use with lead acid batteries (vented,
GEL, or AGM type).
