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 GV-5.
• Never connect the panel negative to the battery negative, as your batteries may be damaged.
Note: In the GV-5, the positive side of the battery is connected internally to the positive side of the solar panel.
• Do not use blocking diodes for single-panel installations. The GV-5 prevents reverse-current ow.
• 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 GV-5 at the coldest possible expected temperature.
• Optional - Genasun Overdrive for Oversized Solar Arrays: The GV-5 can be programmed with adaptivepower-limiting technology
(P/N GV-5-XX-CV), allowing it to be used with solar arrays in excess of its ratedpower. If an oversized array is connected, the GV-5 will
deliver the most power possible while keeping itselectronicsata safetemperaturefor long-term operation. This GV-5 automatically
adjusts fortemperatureand other factorstosmoothly deliverpower at up to 85 °C ambient. If the GV-5 will be used with a solar panel
or array with a short circuit current (Isc) of more than 8 A, the GV-5 input should be protected with a fast-acting fuse or circuit breaker
of 10 A and rated for the maximum solar panel voltage. Note that solar input voltage limits MUST ALWAYS be respected. Exceeding
the input voltage limit will void the warranty and damage the GV-5. For more info about the Genasun Overdrive, please visit the blog

CONNECTING THE LOAD
Connect the load(s) to the LOAD+ and LOAD- terminals.
• The load draw should not exceed 5 A continuous.
• Larger loads should be connected directly to the battery. The GV-5
will not be able to protect the battery against over-discharge (low
voltage disconnect (LVD)) in this case.
CONNECTING THE BATTERY
Connect the battery to the BATT+ and BATT- terminals.
• A small spark while connecting the battery is ok.
CAUTION, RISK OF FIRE OR EXPLOSION: Do not make
the nal battery connection near lead-acid batteries
that have recently been charging.
