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 different 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
• GVB-8-Li-14.2V-WP: 12V (4s) Lithium Iron Phosphate
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.
