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 the wiring sequence shown below.
(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.
