The solar power system feeds the alternating current via an additional feed-in me-
ter (used for feed-in tariff) directly to the grid system of the grid system operator
and is then available to all consumers connected to the grid. The energy used by
the electricity consumers is then billed as normal using the existing consumption
meter.
Among other components, the inverter contains a central control unit and an in-
ternal data logger. The inverter can be optionally extended with a StecaGrid Vision
display unit. See

for further information about accessories.
Your installer can, of course, also give you more information about the options
and accessories that are available.
In the following technical documentation, the installer and user are given a de-
scription of the technical features that are necessary for the installation, function,
operation and use of the inverter.
