Installation & System Connections:
•
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.

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 can be mounted in any orientation.
• do not expose to water (Please see model GVB-WP FoR WateRPRooF VeRsIon).
• 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.
Note:
do not install this controller in a Golf Cart. Genasun offers the GVB-WP for Golf
Carts and other applications where water resistance is needed.
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.

do not use blocking diodes for single-panel installations. the GVB 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.
