Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours). The
energy is the accumulation of power over time. for example, your inverter operates at a constant
power of 5000 W for half an hour and then at a constant power of 2500 W for another half an
hour, it has fed 3750Wh of energy into the power distribution grid within that hour.
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an instantaneous
value. It displays the power your inverter is currently feeding into the power distribution grid.
Power rate
Power rate is the radio of current power feeding into the power distribution grid and the
maximum power of the inverter that can feed into the power distribution grid.

-3-
Power Factor
Power factor is the ratio of real power and apparent power. They are identical only when current and
voltage are in phase and the power factor is 1.0. The power in an ac circuit is very seldom equal to
the direct product of the volts and amperes. In order to find the power of a single phase ac circuit the
product of volts and amperes must be multiplied by the power factor.
PV
Abbreviation for photovoltaic
wireless communication
The external wireless communication technology is a radio technology that allows the inverter and
other communication products to communicate with each other. The external wireless communication
does not require line of sight between the devices and it is selective purchasing.
2.Safety
2.1 Intended Use
The unit converts the DC current generated by the photovoltaic (PV) modules to grid- compliant
alternating current and performs single-phase feed-in into the electricity Grid.
SP3600M,SP4200M,SP4600M,SP5000M,SP6000M inverters are built
according to all required safety rules. Nevertheless, improper use may cause lethal hazards for the
operator or third parties, or may result in damage to the units and other property.
Principle of a PV plant with this SPXXXXM single-phase inverter
The inverter may only be operated with a permanent connection to the public power grid. The inverter
is not intended for mobile use. Any other or additional use is not considered the intended use. The
manufacturer/supplier is not liable for damage caused by such unintended use. Damage caused by
such unintended use is at the sole risk of the operator.
PV modules Capacitive Discharge Currents
PV modules with large capacities relative to earth, such as thin-film PV modules with cells on a metallic
substrate, may only be used if their coupling capacity does not exceed 470nF. During feed-in operation,
a leakage current flows from the cells to earth, the size of which depends on the manner in which the
PV modules are installed (e.g. foil on metal roof) and on the weather (rain, snow). This "normal"
leakage current may not exceed 50mA due to the fact that the inverter would otherwise automatically
disconnect from the electricity grid as a protective measure.

House grid
Energy flows into the house grid. The consumers connected, for
example, household devices or lighting, consume the energy.
The energy left over is fed into the public grid. When the SP
Series is not generating any energy, e.g., at night, the
consumers which are connected are supplied by the public
grid.The SP Series does not have its own energy meter. When
energy is fed into the public grid, the energy meter spins
backwards.
Public grid
Energy is fed directly into the public grid. The SP Series is
connected to a separate energy meter. The energy produced is
