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. The GV-10 prevents reverse-current flow.
•
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
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.
The GV-10 has a
MULTI
COLOR
LED.

CAUTION, RISK OF FIRE OR EXPLOSION: Do not make the final battery connection near lead-acid
batteries that have recently been charging.

Note:
Voltages above 25V applied to the battery terminals will immediately destroy the GV-10.
We recommend wiring the controller directly to the battery through its own circuit, and not
through any battery switch or selector. Do not share wiring between the GV-10 and an alternator.
