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.
Note: In the GVB-8-WP, 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 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.
