Avoid the risk of electric shocks during installation and avert any damage due to overcurrent: with no high voltages and self-limiting features, our AC system is safe by design. An automatic shutdown function protects the building in case of an external emergency.
Safe handling at all times
No more handling of dangerous DC high voltages! During the installation of a Solarnative PV plant, all AC cabling is completely voltage free, and the DC voltage is limited to the uncritical potential of a single PV module, i.e. ~40 V. The cable handling does not require any specific safety precautions, and the transformer-based topology of the Solarnative Power Stick micro-inverter leads to a fail-safe galvanic isolation. As long as there is no connection to the main grid, the system is switched off.
Compliant with rapid-shutdown regulations
While string-inverter based PV systems cannot be switched off, this function is crucial in the event of a fire to allow the use of water in fire-fighting. Therefore, the Solarnative micro-inverters automatically switch off, as soon as the PV plant is disconnected from the grid. Moreover, NS-protection is included in each inverter.
The Solarnative system is compliant with NEC 2020 section 690.12 Rapid Shutdown Regulation and German NS-protection requirements according to VDE-AR‑N 4105:2018–11
Self-limiting system protection
Our micro-inverters are self-limiting. Each inverter measures the string current and if it is too high, i.e., above the maximum string current of 20 A, the inverter simply reduces its power accordingly. Thus, there is never any safety risk or risk of damaging the system, even when too many modules are added to a string.
This self-limiting functionality can also help boost the energy yield of a PV plant. It allows installing a higher peak wattage, because during maximum insolation, the overcurrent will be limited by the system, while the power output is increased under lower lighting conditions.
