Requirements for the Home Installation at the SolMate® Operating Location:
• Ensure that only one SolMate® is operated per phase in the household!
• The rated current of the circuit breaker for the circuit where SolMate® is operated must not
exceed B 16 A. For older systems, a reduction to B 13 A and an inspection of the respective
circuit by a qualified electrician are recommended.
• A functioning RCD with IΔn ≤ 30 mA must be installed.
It is the responsibility of the SolMate® operator to ensure that all components are securely
weatherproofed and weighted down to prevent any personal injury or property damage.
SolMate® is a Class I protection device, meaning its metal housing is connected to the protective
conductor. During grid operation (grid mode), the grid voltage is passed through to the device
socket. In island mode, this electrical connection is disconnected. Instead, the device socket
provides a galvanically isolated, ground-isolated voltage that allows energy to be drawn from the
battery (maximum 1000 W with pure sine wave output). For safety reasons, only one Class I
device (with a metal housing) may be operated at this socket at a time in island mode. However,
multiple Class II devices can be connected simultaneously.
Lightning Protection
SolMate® must be operated within the protection zone of a building equipped with an existing
lightning protection system, and the required separation distance (see EN 62305 or VDE 0185-
305) must be observed. This means SolMate® and its components (including cables) must be
positioned with sufficient distance from lightning rods, rainwater downpipes, and other grounded
metal parts. Additional lightning protection measures depend on the specific local and structural
conditions and can be determined by experts in lightning protection (usually qualified electricians
possess this expertise). If SolMate® and its components are operated within the protection zone
with sufficient separation distance, no further lightning protection measures are necessary. If no
building lightning protection is available, ensure that SolMate® and its components (including
cables) are not positioned on exposed parts of the building. The distance of all SolMate®
components from the ground should be kept as small as possible, and cable lengths should be
minimized. If the cable length exceeds 10 meters, an SPD (Surge Protection Device) of Class 1
must be installed at the point where the electrical cable enters the building. A local qualified
electrician can provide advice and assistance in this regard.
SolMate® should be subjected to periodic visual inspections and after extreme weather
conditions. Check that the cables, connections, and the system itself are undamaged. If any
component is damaged, SolMate® must be immediately taken out of operation.
To do this, unplug SolMate® from the power grid, disconnect all system connections, and turn off
SolMate® (see “TURNING SOLMATE® ON AND OFF” on p.17). Arrange for proper repair by a
qualified professional.
