Product Manual

This manual contains important instructions for the GV-Boost GVB-8-Pb-**V-WP and GVB-8-Li-**.*V-WP solar charge controllers that
shall be followed during installation and maintenance. Various models of the GVB-WP are available to charge dierent battery types as
follows:
• GVB-8-Pb-12V-WP: 12V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-24V-WP: 24V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-36V-WP: 36V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-48V-WP: 48V Lead-Acid/AGM/Gel/Sealed/Flooded
Consult your battery charging specifications to ensure that the GVB is compatible with your chosen batteries.
The GVB-8-WP includes an external 10A In-Line fuse rated for the maximum battery voltage.
WARNING: EXPLOSION HAZARD. DO NOT CONNECT OR DISCONNECT WHEN ENERGIZED. DO NOT REMOVE OR REPLACE FUSES UNLESS
POWER HAS BEEN DISCONNECTED OR THE AREA IS FREE OF IGNITIBLE CONCENTRATIONS. ATTENTION: RISQUE D'EXPLOSION. NE PAS
CONNECTER NI DÉCONNECTER PAS LORSQU'IL EST SOUS TENSION. NE PAS CONNECTER LE CIRCUIT ALORS QUE EST VIVANT OU
A MOINS QUE LA ZONE EST LIBRE DE CONCENTRATIONS IGNITAIRES. CAUTION for the GVB-8-Pb-**V-WP (Lead-Acid Versions Only):
INTERNAL TEMPERATURE COMPENSATION. RISK OF FIRE, USE WITHIN 0.3 m (1 ft) of BATTERIES. Lead-acid batteries can create
explosive gases. Short circuits can draw thousands of amps from a battery. Carefully read and follow all instructions supplied with the
battery. DO NOT SHORT CIRCUIT the solar array when plugged into the controller. DO NOT MEASURE SHORT CIRCUIT CURRENT of the
array while connected to the controller. This may damage the controller, and such damage will not be covered under warranty. Grounding
is not necessary for operation and is at the user's discretion. If the GVB-WP is to be used with a solar array electrically connected to
earth ground, please note the following: WARNING: THIS UNIT IS NOT PROVIDED WITH A GFDI DEVICE. Consult Article 690 of the National
Electrical Code (or the standards in force at the installation location) to determine whether a GFDI is necessary for your installation.
WARNING: THIS UNIT IS NOT PROVIDED WITH DISCONNECT DEVICES. Consult Article 690 of the National Electrical Code (or the standards
in force at the installation location) to determine whether disconnect devices are necessary for your installation.
