AC Switchboard
The AC switchboard is the location for all 230V connections and safety devices.
Circuit Breakers
Main Switch (Normal Supply)
Off: Shuts off all house loads and area loads (typically shed power) that are powered by the system.
On: The house switchboard, house circuits and all connected outbuildings are energised.
Sub-Board Isolator
Used to supply power to the house switchboard, it can be used to isolate only the house switchboard while
leaving other local area power circuits energised for example.
Residual Current Devices/Circuit breakers
These devices marked “Power and “Light” are conveniently reserved for directly powering up added local
area power loads such as in the shed where the equipment is installed. They provide protection against over
current or earth leakage faults at this location. Note: Does not provide protection to loads connected via
the house Sub board circuit isolator, this is typically proved at the household switchboard.
Generator Circuit breaker/Isolating Switch
This provides over current protection or allows manual isolation of the 230V AC fuel powered generator set.
Contactor (marked cont.)
Note: Not applicable to EM model Inverter/chargers
This device automatically isolates any generator sockets or plugs from the AC switchboard once unplugged.
The device has a small flag status indicator in a clear window; a
red
flag indicates the circuit contacts are
connected, while a
green
flag indicates the device is isolating the circuit. No user intervention is required.
Switchboard Meters
House Energy Meter: a digital meter keeping record of the entire households’
energy consumption (kWh). Press the mode button twice to view instantaneous ac
power consumption in kilowatts.
Generator Meter: a digital meter keeping record of all generator energy delivered into the system (kWh)
Note: This meter will only show digits when the generator is running.
