All about safety for solar energy Using free energy – safe for its consumers. The Sun provides 15,000 times more energy than consumed worldwide – reliably and free of charge. Modern photovoltaic installations harness this energy by using solar cells on the roof, which convert the sunlight efciently and sustainably into electric power. The generation of renewable electricity offers great potential for the future, but means a special challenge, too. The irresistible power of the sun has to be restrained and professionally protected to prevent dangerous situations. For this reason, Eaton...

Eaton’s solutions Actively shape the future with safe photovoltaic systems and Eaton. Photovoltaic power plants convert sunlight directly into electrical energy. For this purpose, photovoltaic modules are used. A differentiation is made between grid-independent systems and systems coupled to the power grid. Photovoltaic systems that are coupled to the power grid feed the generated power directly into the electrical grid. There is no need for sophisticated intermediate storage. A system of this type consists of photovoltaic modules, one or more inverters and switchgear for operation,...

The energy of the sun – the quality of Eaton. The total power of a photovoltaic system does not only depend on the area of installed PV-modules but also on the adjustment and slope of the modules. Also components such as the inverter greatly affect the efciency. By using Eaton’s inverters, maximum power is ensured.

Safe disconnection and protection of PV arrays Compact disconnectors for inverters customized enclosures or inverters. They are installed on 35 mm top-hat rails; their terminals facilitate the connection of all conventional conductor types. Eaton offers both enclosed and open switch-disconnectors. P-SOL open switchdisconnectors are intended for The IEC 60364-7-712 standard requires the use of a switch-disconnector between the photovoltaic array and the inverter. Eaton provides enclosed and open switch-disconnectors for voltages up to 1000 V DC. They can be used to establish separate...

A house is on re. A re-ghting appliance approaches. The re ghters climb out, see a solar installation – and can do very little. The re services can frequently do little else than rescue persons and animals and prevent neighbouring buildings from catching re. The reason being that PV installations generate voltages up to 1000 V, which are still generated even after the power inverter is switched off. The Eaton reman’s switch SOL30-SAFETY provides the solution, which disconnects the cable from the solar panels to the power inverters facilitating re ghting without an electrical hazard. Small...

String protection makes sense if the PV system has 3 or more strings and can be made with a DC fuse disconnector or a DC string circuit breaker. In addition to fuses, protection of photovoltaic strings is provided by string circuit-breakers. String protection devices protect photovoltaic modules from fault currents. They prevent reverse currents from intact modules to modules with a short circuit. The advantage of string circuit breakers, in comparison to fuses, is that they are immediately ready for use after a trip, when the cause of the trip has been remedied. Eaton offers both...

Safety and comfort for the building AC switchgear for buildings Miniature circuit-breakers (MCBs) and residual current devices (RCDs)) Digital residual current circuit-breakers (RCCB) Residual current breakers with overcurrent (RCBO) Distribution boards Digital technology makes it possible to achieve a new level in tripping accuracy, which helps to avoid unwanted tripping. This occurs, for example, as a result of permanent discharge currents on electrical devices or temporary disturbances during a thunderstorm. Eaton is the rst company offering the digital residual current device, which...

The safety of Eaton Safe disconnection: In case of re or ooding, the current grid will be shut down by the regional electricity supplier or the re brigade. Eaton provides you with extra safety: Remote controlled switch disconnectors ensure the disconnection of the voltage producing modules from the grid. Safe maintenance: Whether the photovoltaic system has to be maintained or the panels cleaned up – Eaton’s DC switch disconnectors disconnect the panels from the system and help to avoid dangers while working on the roof. Safe protection: Even if a lightning arrester protects your home from...
