TOOLS AND MATERIALS NEEDED

 

• Screwdriver.

• Multimeter.

 

Note. If the solar controller was purchased with a Go Power! RV Solar Power Kit the UV resistant wire is included. For instructions regarding the Go Power! RV Solar Power Kit installation, please refer to the installation guide provided with the kit

 

INSTALLATION AND WIRING

 

STEP 1: CHOOSE AN INSTALLATION LOCATION The GP-MPPT-PRO controllers are designed to be mounted vertically in a battery box with sufficient ventilation and should be as close to the battery as possible. Adequate space above and below the controller is vitally important to ensure proper natural convection for heat dissipation as shown below. Avoid installing the controller in a place with direct sunlight, high temperature, and/or water.

 

 

STEP 2: MARK THE MOUNTING POSITION ACCORDING TO THE MOUNTING DIMENSIONS OF THE CONTROLLER. First, place the installation guide plate 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. 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.

 

 

 

 

 

 

We recommend a wiring sequence shown below.

 

 

Note. 

 

1) Note that the battery fuse shall be installed as close as possible to the battery terminal. The recommended distance is considered to be not more than 150mm.

2) The battery temperature is 25°C (fixed value) when the controller is not connected to a remote temperature sensor.

 

BATTERY VOLTAGE SENSE

 

The voltage measured at the battery input on the GP-MPPT-PRO-60 may differ slightly from the voltage measured directly at the battery bank terminals. This is especially true when the GP_MPPT-PRO-60 is bulk charging and is due to connection and cable resistance. The Battery Voltage Sense input enables the GP_MPPT-PRO to measure the battery terminal voltage precisely with small gauge wires that carry very little current and, as a result, have no voltage drop.

 

A battery voltage sense connection is not required to operate your GP_MPPT-PRO-60 and it will charge your battery bank accurately without this input. However, it is recommended that these voltage sense wires are connected to ensure that the voltage and diagnostic displays are very accurate. The voltage sense wires are not included in the box with the GP-MPPTPRO-60. Wires with the following requirements can be used and should be cut to length as required to connect the battery to the voltage sense input on the GP-MPPT-PRO-60.

 

The wires may be routed with the power conductors.

 

• 16 to 24 AWG (1.0 to 0.25 mm2)

• Twisted pair cable is recommended but not required

• UL rated 300 Volt

• Maximum length for each wire is 50 ft (15.24 m)
