3. Installation
3.1. Location of the MPPT
Try and keep the distance between the product and the battery to a minimum in order to minimise cable
3.2. MPPT grounding, detection of PV array insulation faults & Earth fault alarm
notification
The RS will test for sufficient resistive isolation between PV+ and GND, and PV- and GND.
In the event of a resistance below the threshold (indicating an earth fault), the unit will stop charging and display the error.

Isolated SmartSolar MPPT RS
For best operating results, the MPPT should be placed on a flat vertical surface. To
ensure a trouble free operation, it must be used in locations that meet the following
requirements:
a) Do not expose to water, rain or moisture.
b) Do not place in direct sunlight. Ambient air temperature should be between -20°C
and 40°C (humidity & 95% non-condensing).
c) Do not obstruct airflow. Leave at least 30 centimeters clearance above and below
the MPPT.
When the unit is running too hot, it will shut down. When it has reached a safe
temperature level the unit will automatically restart again.

clearance.
This product contains potentially dangerous voltages. It should only be installed under
the supervision of a suitable qualified installer with the appropriate training, and
subject to local requirements. Please contact Victron Energy for further information
or necessary training.
Excessively high ambient temperature will result in the following:
·
Reduced service life.
·
Reduced charging current.
·
Reduced peak capacity, or shutdown of the MPPT.
Never position the appliance directly above lead-acid batteries. The MPPT RS is
suitable for wall mounting. For mounting purposes, a hook and two holes are provided
at the back of the casing. The device must be fitted vertically for optimal cooling.
For safety purposes, this product should be installed in a heat-resistant environment.
You should prevent the presence of e.g. chemicals, synthetic components, curtains or
other textiles, etc., in the immediate vicinity.
