This manual contains important instructions for the GV-Boost GVB-8-Pb-**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-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.
Carefully follow these instructions.
CAUTION for the GVB-8-Pb-**V-WP:
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 will DESTROY the controller, and such damage will not be covered under warranty.
DO NOT USE WITH LITHIUM BATTERIES. See our GVB-Li series for lithium applications.
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.
Safety Instructions:

Use only 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.

Installation & System Connections:
MOUNTING
Mount the controller near your battery securely using the holes provided on the
enclosure’s flanges or with a means appropriate to the application.
• Mount near battery.
• The GVB-WP can be mounted in any orientation.
• Do not mount in direct sunlight or near a source of heat.
• Allow adequate airflow around the controller to achieve maximum output capability.
e
• Connections should be made according to Article 690 of the National Electrical Code (NFPA 70)
or the standards in force at the installation location.
• Electrical connections may be made in any order; however the
sequence below is recommended.
Note: Make sure to inspect the controller at least once per year to ensure proper
performance. Please see the Inspection & Maintenance section in this guide.

VOLTAGE BOOSTING MPPT SOLAR CHARGE CONTROLLER
CONNECTING THE SOLAR PANEL
Connect the solar panel to the +PANEL and –PANEL terminals.
• In most applications, the panel should be connected only to the GVB-WP.
• The LED may blink red until a battery is connected.
• Do not use blocking diodes for single-panel installations. The GVB-WP prevents
reverse-current flow.
• If multiple panels are being used in parallel, blocking diodes are recommended in
series with each panel, unless the panel manufacturer recommends otherwise.
• Solar panel voltage rises in cold weather. Check that the solar panel open circuit
voltage (Voc) will remain below the maximum input voltage of the GVB-WP at the
coldest possible expected temperature.
CONNECTING THE BATTERY
Connect the battery to the +BATT and –BATT terminals.
• A small spark while connecting the battery is ok.
• Any loads should be connected directly to the battery. The GVB-WP does not
provide protection against over-discharge.
CAUTION, RISK OF FIRE OR EXPLOSION: Do not make the final battery connection
near lead-acid batteries that have recently been charging.

The GVB-WP has a
MULTICOLOR LED.
Learn about this indicator
on the following page.

LED RUN/CHARGE INDICATION
Standby: The battery is connected properly and ready to charge
when solar panel power is available.
2 SEC. BETWEEN BLINKS
Charging (low current, input current less than ~3.5A):
FAST & SHORT BLINKS
Charging (high current, input current more than ~3.5A):
LONGER BLINKS
Charging (current limit): charging at current limit.
The GVB is overloaded and limiting input current. Check that the
solar panel rating is within the GVB’s input specifications.
LONG, THEN SHORT BLINKS
Battery Charged: The battery is in the absorption
or float charging stage.
SOLID LED
LED ERROR INDICATION
Overheat: The controller’s internal temperature is too high.
SETS OF 2 RED BLINKS.
Overload: The GVB has been overloaded.
This could be caused by changing the solar panel connections
while the controller is operating.
SETS OF 3 RED BLINKS.
Battery voltage too low: The controller cannot begin charging
due to low battery voltage. Charge the battery by some other
means before use.
SETS OF 4 RED BLINKS
Battery voltage too high: Check that the correct GVB has been
selected for the nominal system battery voltage. If the nominal
battery voltage is correct, check the functioning of other
chargers that may be connected to the system. This error can
also be caused by a disconnected battery or blown fuse.
SETS OF 5 RED BLINKS.
Internal Error: Contact your dealer for assistance.
2 LONG BLINKS, FOLLOWED BY ANY NUMBER
OF SHORT BLINKS.

Status Indication:

Troubleshooting
If the LED indicator does not light with a battery connected, or blinks the over-battery-
voltage error, or the controller does not charge, the fuse may be blown. The GVB-WP fuse
is located in a black waterproof in-line fuse holder in the positive battery line. If the fuse is
blown, replace it with a 10A fast-acting ATO or ATC fuse rated for at least 58V. Automotive
fuses are typically rated to 32V, and are not acceptable. We recommend Littelfuse part
number 142.6185.5102, rated to 58V.
The most common causes of blown fuses are:
• Connecting the GVB-WP to the battery backwards
• Shorting the solar panel input while the GVB-WP
is charging. In this case, there may be other internal
damage to the controller.
