Separated or safety extra-low voltage (SELV) IEC defines a SELV system as "an electrical system in which the voltage cannot exceed ELV under normal conditions, and under single-fault conditions, including earth faults in other circuits". The acronym may variously stand for safety extra-low voltage or separated extra-low. The Cabling for ELV systems, such as in (RAPS), is designed to minimise energy losses while maximising safety.

A standard off-the-shelf solar panel will have about 18 to 30 volts output, whereas a higher voltage output would be 60 or 72-volt panels. The higher voltage of course means more power in one go, which could mean you can run a larger load at the same time.

Der Markt bietet Photovoltaikmodule in verschiedenen Ausführungen, zum Beispiel MIT monokristallinen oder polykristallinen Solarzellen. Monokristalline Module sind teuer, aber effektiv: Sie erreichen einen Wirkungsgrad zwischen 20 und 22 %. Wer eine Powerstation MIT Solarstrom aufladen will, kann sich das EcoFlow Solarpanel 160 W näher ansehen. Unter den flexiblen Solarmodulen empfiehlt sich das semiflexible Modell Offgridtec PCB‑ETFE.
