220V inverter DC voltage

An inverter converts a 220 Volt DC voltage (battery) into an AC voltage (230V-50Hz). The standard output voltage is 230 Volt, 50Hz with a pure sine wave. This means that this inverter supplies the same type of voltage as the wall socket. This allows any electrical device to work on it. [pdf]

Voltage inverter DC 110V to AC

An inverter converts a 110 Volt DC voltage (battery) into an AC voltage (230V-50Hz). The standard output voltage is 230 Volt, 50Hz with a pure sine wave. This means that this inverter supplies the same type of voltage as the wall socket. This allows any electrical device to work on it. [pdf]

Voltage of two strings of photovoltaic panels

Sometimes the system voltage required for a power plant is much higher than what a single PV module can produce. In such cases, N-number of PV modules is connected in series to deliver the required volt. [pdf]
