INSTALLATION AND WIRING
STEP 1: CHOOSE AN INSTALLATION LOCATION
The following things should be considered when choosing an installation location for GP-RVC-30-MPPT controllers.
• The controller should be installed indoors where it is safe from water or condensation
• Avoid installing the controller in direct sunlight
• Mount the controller to a non-flammable surface
• For best thermal performance mount the controller vertically with power terminals facing downward, this will encourage natural convection through the heatsink and keep it cooler
• There should be at least 6 inches of air gap above and below the controller for the natural convection to occur effectively
• Locate the controller as close to the battery as possible (but not directly above the battery to prevent potential damage due to gassing of the battery), this will keep the battery wires short and prevent voltage drop
• Ensure any enclosed space where the controller is mounted is well ventilated, this will prevent heat buildup that could lead to derating of the controller
STEP 2: MARK THE MOUNTING POSITION ACCORDING TO THE MOUNTING DIMENSIONS OF THE CONTROLLER
First, place the controller at a proper position and use a marking pen to mark the mounting points. Drill 4 mounting holes of the appropriate size at the 4 marks. Fix screws into the upper two mounting holes.
STEP 3: FASTEN THE CONTROLLER
Align fixed holes of the controller with the two pre-fixed screws and hang the controller up. Then fix the lower two screws.
STEP 4: WIRING
Wiring and installation must comply with national and local electrical code requirements.
The wire from the solar array most commonly enters the RV through the fridge vent on the roof or by using the Go Power! Cable Entry Plate (sold separately) that allows installers to run wires through any part of the roof. PV connections should connect directly to the controller.
NOTE: Positive and negative battery connections must connect directly from the controller to the batteries and positive and negative PV connections must connect directly from the solar array to the controller. Wires that are as short as possible and adequately sized (see table below) should always be used. Use of a positive and/or negative distribution bus that is properly sized is recommended between the controller and battery – do not stack wires on the battery terminals.
Warning: Danger, Electric shock hazards! We strongly recommend connect a fuse or circuit breaker to the PV array and battery terminals to prevent electric shock hazards during wiring or error operation, and make sure that fuse or circuit breaker is disconnected before wiring.
(1) The battery fuse should be installed as close as possible to the battery terminal. The recommended distance is not more than 150mm.
(2) The battery temperature will read 25°C (fixed value) when the controller is not connected to a remote temperature sensor.
