4. EQUIPMENT DESCRIPTION
The inverter uses high frequency pulse-width modulated technology
and the latest field-effect devices. This system allows the
inverter to run with high efficiency and to operate silently. Each
inverter is fitted with color-coded battery leads, two output plugs
for immediate convenience and an output terminal block for ease of
connection to the complete installation. All functions are
microprocessor controlled using the latest DSP technology.
An LCD screen enables viewing of many parameters and a keyboard to
facilitate customers changing their settings.
The following parts of the inverter should be identified:
- Free standing steel casing
- Removable cover
- 8mm DC input studs
- 6mm AC output studs
- LCD and keypad on top cover
- Input and output circuit breakers on the front cover
(b)Explanation of Features
Battery Low Protection
A lead-acid battery will suffer permanent damage if it is allowed
to remain in a fully discharged state for even a short period of
time. GOLAND CENTURY inverters incorporate a battery-low shut-down
circuit which switches off the inverter when the battery voltage
falls below a certain level. The inverter will automatically
restart when the battery level returns to normal.
Electronic Overload Protection
The inverter is capable of supplying 1.5 times its rated output
power for 10 seconds. This enables it to handle motor starting
currents and other surges that occur when equipment is switched on.
Overloads in excess of the above, short circuits and lesser
overloads of longer duration will cause the inverter to switch off.
After overload, the inverter will not operate until the reset
button has been pushed. On pressing the reset the inverter will
start up again. Please check first why your inverter is overloaded
and remove the excess load before re-initializing the inverter.
Galvanic isolation in the inverter achieves maximum resistance
between the battery and the main output. This eliminates the chance
of problems occurring where there is an existing connection between
the battery and earth.
Incorrect Battery Voltage Protection
If during charging of the battery, the battery voltage rises to an
unacceptable level the inverter will switch off to protect the
electronic components. It will automatically restart once the
voltage has returned to normal.
If the inverter is connected to a battery of too high voltage, the
inverter will switch off. Please note that this only operates to
