This manual contains important instructions for the GV-10-Pb-12V and GV-10-Li-**.*V solar charge controllers that shall be followed
during installation and maintenance. Various models of the GV-10 are available to charge dierent battery types as follows:
• GV-10-Pb-12V: 12V Lead-Acid/AGM/Gel/Sealed/Flooded
• GV-10-Li-12.5V: 11.1V (3s) Lithium Cobalt/Polymer
• GV-10-Li-14.2V: 12.8/13.2V (4s) Lithium Iron Phosphate
• GV-10-Li-16.7V: 14.8V (4s) Lithium Cobalt/Polymer
Consult your battery charging specifications to ensure that the GV-10 is compatible with your chosen batteries.
Carefully follow these instructions.
CAUTION for the GV-10-Pb-12V(Lead Acid Version 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. Use only 12V lead-acid batteries with the GV-10-Pb-12V.
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.
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.
Safety Instructions: 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.

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 GV-10 can be mounted in any orientation.
 Do not expose to water.
 Do not mount in direct sunlight or near a source of heat.
 Allow adequate airflow around the controller to achieve maximum output capability.
 For outdoor use, the controller must be housed in an enclosure providing protection
at least equivalent to NEMA Type 3.
SELECTING THE BATTERY TYPE (LEAD-ACID / PB MODEL ONLY)
Your GV-10-Pb-12V controller is supplied set to the “SEALED” charging profile, which is appropriate for most
types of sealed lead-acid and gel batteries, as well as some types of AGM batteries. A “FLOODED” setting is
available for flooded batteries and other types of AGM batteries. The “FLOODED” setting includes equalization
charging. Please consult the specification table at the end of this manual to determine the best setting for
your battery type. To change your GV-10 controller to the “FLOODED” setting, unscrew the four screws on the

batteries, do not install the jumper.

CONNECTING THE SOLAR PANEL
Connect the solar panel to the +PANEL and –PANEL terminals. While connecting the battery first
will not damage the GV-10, we recommend connecting the panel first. This eliminates the risk of short-
circuiting the panel while the GV-10 is operating, which can cause damage.
 In most applications, the panel should be connected only to the GV-10.
 Do not use blocking diodes for single panel installations; they reduce system
performance with no benefit.
 Multiple panels may be connected in parallel up to the maximum power limit of the controller, with
a blocking diode used for each panel (unless otherwise recommended by the panel manufacturer).
These panels should be the same model and facing the same direction, otherwise we recommend
using a separate controller for each panel.
 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 GV-10 at the coldest possible expected
temperature.
Note: In the GV-10, the negative side of the battery is connected internally to the negative side of the
solar panel.

 Electrical connections may be made in any order; however the sequence below is
recommended.
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 GV-10 does not provide
protection against over-discharge.

Note: Make sure to inspect the controller at least once
per year to ensure proper performance. Please see the

Troubleshooting
If the LED indicator does not light, check that there is battery voltage present on the GV-10 battery terminals. The GV-10 will not operate without a
battery. If there is battery voltage present, check the fuse inside the GV-10 by removing the four screws on the bottom of the enclosure. If the fuse is
blown, replace it with a 20A fast-acting ATO or ATC fuse rated 32V or higher.
The most common causes of blown fuses are:
