This manual contains important instructions for the GV-Boost GVB-8-Pb and GVB-8-Li solar charge controllers that shall be followed during installation and maintenance.
Various models of the GVB-8 are available to charge dierent battery types as follows:
• GVB-8-Pb-12V: 12V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-24V: 24V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-36V: 36V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-48V: 48V Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-CV: Custom Lead-Acid/AGM/Gel/Sealed/Flooded
• GVB-8-Pb-PCB: Multi-Stage Lead-Acid/AGM/Gel/Sealed/Flooded
Consult your battery charging specications to ensure that the GVB is compatible with your chosen batteries.
The GVB-8 includes a 10A fast-acting ATO fuse rated for the maximum battery voltage.
UL SAFETY AND HAZLOC WARNING: EXPLOSION HAZARD. DO NOT SERVICE, CONNECT, DISCONNECT, OR CHANGE FUSES UNLESS THE AREA IS FREE OF IGNITABLE
CONCENTRATIONS. ATTENTION: RISQUE D’EXPLOSION. NE PAS RÉPARER, CONNECTER, DÉCONNECTER, OU REMPLACER LES FUSIBLES À MOINS QUE LA ZONE SOIT
EXEMPTE DE CONCENTRATIONS INFLAMMABLES.
WARNING: REPLACE ONLY WITH THE SAME RATINGS AND TYPE OF FUSE. DISCONNECT ALL SOURCES OF SUPPLY BEFORE SERVICING. NON-ISOLATED. ONLY VERSIONS WITH
VOLTAGE ABOVE 42.4V - WHEN A GROUND FAULT IS INDICATED, BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE UNGROUNDED AND HAZARDOUS. ATTENTION:
REMPLACER SEULEMENT AVEC LE MÊME TYPE ET VALEUR NOMINALE DE FUSIBLE. DÉBRANCHER TOUTES LES SOURCES D’ALIMENTATION AVANT L’ENTRETIEN. PAS ISOLÉ.
SEULES LES VERSIONS DE TENSION SUPÉRIEURES À 42,4V - LORSQU’UN DÉFAUT À LA TERRE EST INDIQUÉ, LES BORNES DE BATTERIE ET LES CIRCUITS CONNECTÉS PEUVENT
ÊTRE N’EST PAS RELIÉE À LA TERRE ET DANGEREUX.
CAUTION for the GVB-8-Pb (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.
To avoid stress on the GVB-8 and possible damage, DO NOT SHORT CIRCUIT the solar array when plugged into the controller, and DO NOT MEASURE SHORT CIRCUIT
CURRENT of the array while connected to the controller.
Grounding is not necessary for operation and is at the user's discretion. If the GVB-8 is to be used with a solar array electrically connected to earth ground, please note
the following:
