2.1 Appropriate usage
The NTX is a DC to AC grid-tied utility interactive
inverter for use with photovoltaic (PV). In general,
the NTX takes power from a DC source (PV modules)
and converts it to AC power for the utility grid. This
power is delivered first to local loads (household
appliance, lights, motor loads, etc.), with any excess
power fed to the utility. The power consumed by
the local loads reduces the power needed from the
utility. Excess power may actually spin the utility
meter backwards depending on the type of meter
in you system. This power may also be recorded as
power credits by the utility company depending on
the interconnection agreement. An example of basic
system components is shown in figure below.

Remark:
Policies vary from one utility company to another.
Consult with a representative of the local util-
ity company before designing and installing a PV
system.
