Safety Instructions:
This manual contains important instructions for the GV-Boost GVB-8-Pb-**V and GVB-8-Li-**.*V solar charge controllers that shall
be followed during installation and maintenance. Various models of the GVB are available to charge different battery types as follows:
12V Lead-Acid/AGM/Gel/Sealed/Flooded
•
GVB-8-Pb-12V:
24V Lead-Acid/AGM/Gel/Sealed/Flooded
•
GVB-8-Pb-24V:
•
GVB-8-Pb-36V:
36V Lead-Acid/AGM/Gel/Sealed/Flooded
•
GVB-8-Pb-48V:
48V Lead-Acid/AGM/Gel/Sealed/Flooded
•
GVB-8-Li-**.*V:
Custom Lithium Variation
Consult your battery charging specifications to ensure that the GVB is compatible with your chosen batteries.
Carefully follow these instructions.

LITHIUM WARNING:
take caution when working with lithium systems. Genasun li controllers use the CC/CV charging profile
indicated on the controller. CHeCK the specifications of the battery pack to ensure that the CV voltage is correct. Further check that
the power supplied by the solar array and Genasun controller is within the battery specified design limits.

LITHIUM BMS WARNING:
Genasun recommends using a lithium battery with a Battery management system capable of
disconnecting the solar charge controller in the event that any cell in the pack is outside of its rated temperature, current, or
voltage range. Failure to do so may result in property damage, injury or death. Genasun highly recommends the use of a Bms with
cell balancing. Cell balancing is mandatory for lithium-iron phosphate systems.
Use only 10-30 AWG copper conductors suitable for a minimum of 60 degrees C. If operation at high power or at high ambient
temperatures is expected, wire with a higher temperature rating may be necessary.
Inspection & Maintenance
Inspect the controller at least once per year to ensure proper performance.
•
Check for animal or insect damage.
•
Inspect for corrosion / water damage.
•
Inspect the security of all connections.
•
Ensure the solar array does not exceed the maximum input voltage.
•
Repair and clean as necessary.
