Inverter Settings
We will start with the “Inverter” tab and progressively work our way through – setting by setting.
WHEN ECONO
mode is disabled the inverter will run continuously, when
it is enabled the inverter will go into “sleep” mode and consume much
less power if the load is below the pre-set level (5 – 50 watts).
This level is normally chosen to reflect the smallest load you wish to start
the inverter, ie you may choose 20 watts if you want the inverter to start
when you switch on a lamp or you may choose 5 -7 watts if you want it to
run a ‘phone charger’.
INVERTER OUTPUT
sets the normal
NOMINAL AC
Voltage and the
NOMINAL AC
Frequency from the inverter. In Australia this would is
usually 240 volts and 50 Hz. If you are unsure consult your local power
authority.
When your SP PRO is being used in an “On Grid” application reference
to your local grid supply voltage should be considered as this sometimes
varies from the national standard.
DC SHUTDOWN
These figures control how far you will allow your
batteries to become discharged before the inverter will switch itself off.
These lower limits are important as discharging batteries too far can make
them hard to recharge or, in the worst case, damage the batteries. The
first setting outlines the voltage at which the inverter will shutdown with no
load applied to the battery, this includes any DC loads.
The second setting is the shutdown voltage when 100% load is applied.
100% load is when the battery load current is equal to 20% of the battery
capacity (C/5). When the battery load is between these two levels your
SP PRO will calculate a shutdown voltage based on the two voltages you
program.
RECOVERY VOLTAGE
If the inverter shuts down due to low voltage (as in
the last section) this setting allows you to determine at what voltage the
inverter will start itself again. It is wise to make this voltage high enough to
ensure that significant recharging has occurred before it turns on again.
