Solar Grid Interactive
Inverters with Batteries
Grid Interactive Inverters with batteries provide a means of directly connecting
DC renewable sources such as solar photovoltaic arrays and small wind turbines
to the electricity grid. Grid connection ensures that all renewable energy generated
can be utilised. Surplus electricity not used locally is exported through the
grid to other electricity users. Batteries provide reliable power when the grid
supply fails. Systems with batteries can operate in one of several configurations:
Without local load input:
The inverter starts and synchronises to the grid when renewable input becomes
available, and shuts down when renewables are too small to justify operation.This
is useful to interface a wind turbine to the grid, where the battery provides
buffer storage against wind gusts and limits the maximum DC input.
With local load supplied from the grid during normal operation:
If the grid fails, the inverter disconnects and local load can be supplied from
the battery.
With local load supplied from the grid and renewables during normal operation:
If the renewables exceed local load, excess power is exported. If they are less
than the local load, the shortage will be supplied from the grid. If the grid
fails, the inverter disconnects from the grid; local load can be suplied from
the battery and from renewable input. The battery will discharge if renewables
are less than local load, and will charge when they exceed local load.
3 - 5 kW Solar Grid Battery Interactive Inverter
Common to all units:
- Automatic Bypass: Supply is maintained by the generator if the
inverter is off line.
- Data Logging Remote Access: RS232 port, standard data logging
and remote access via modem, satellite, GSM and CDMA technology.
- Cooling: Convection and thermostatically controlled fans.
- Enclosures: Electronics IP50, transformer and heatsink IP23. Weatherproof
enclosures or rack mounting are available on request.
- Protection: Over current trip, over voltage, over temperature,
reverse polarity, fast electronic trip, transient over voltage
protection.
* AC output voltages of 110, 120, 220 and 230 are available on application.
* Other DC voltages between 24 VDC and 120 VDC are available on application.
Standards:All inverters are designed to AS3100 / AS2604 / AS61000.3.5 and the
draft AS/NZ standard for grid connect inverters.
