Do not mount the solar charge controller outdoors or in wet rooms.
Do not subject the solar charge controller to direct sunshine or other sources
of heat.
Protect the solar charge controller from dirt and moisture.
Mount upright on the wall (concrete) on a non-flammable substrate.
Maintain a minimum clearance of 10 cm below and around the device to
ensure unhindered air circulation.
Mount the solar charge controller as close as possible to the batteries (with a
safety clearance of at least 30 cm).
