Inverter Settings
The Inverter tab shows the output settings and minimum battery levels for the inverter to operate within.
Econo Mode
is a legacy setting and is no longer available.
Inverter Output
sets the
Nominal AC Voltage
and the
Nominal AC Frequency
of the
inverter. For example, in Australia this is 240 volts and 50 Hz.
Nominal AC Frequency
is set to 50Hz and cannot be changed with firmware versions
14.00 and above. With older versions of firmware 50Hz or 60 Hz may be selected
DC Shutdown uses battery voltage to
control how far the batteries will discharge before
the inverter will switch itself off. These settings are important as discharging batteries too
far can make them hard to recharge or even damage the batteries.
Battery 0% Load
is the voltage at which the inverter will shutdown with no load applied
to the battery including any DC loads.
Battery 100% Load
is the shutdown voltage when
100% battery load is applied. 100% battery load is when the battery current is equal to
20% of the battery capacity (C/5). When the battery load is between these two levels the
SP PRO will calculate a shutdown voltage based on these two voltages.
Battery load is only the energy coming from the battery. As an example, in an AC Coupled
system with no AC Source, 2 kW of AC Load and 2 kW of solar there will be NO load on
the battery so the DC shutdown will be at the
Battery 0% Load
voltage .
Recovery Voltage
When the inverter shuts down due to low voltage this setting is the
voltage at which the inverter will start up again. It is wise to make this voltage high enough
to ensure that sufficient recharging has occurred before the inverter turns on again.
SoC Shutdown
.(Only available when SoC Control is Enabled) Programs the inverter to
shutdown in response to the state of charge of the battery. When enabled the
Shutdown
SoC
can be set anywhere between 0 and 100%. For a lead acid battery this will generally
be 40-60% but confirm this with the battery supplier.
To Recover from either a Low battery voltage or Low SoC shutdown in a system with AC
coupled solar, connect an AC Source (either grid or generator) to the SP PRO. The SP PRO will
synchonise to the AC Source and start charging the battery bank.
In a well designed Off Grid system the batteries should only get to the Shutdown SoC during a fault condition
(e.g. Generator failed to start).
For a well designed Solar Hybrid (On Grid) system the Shutdown SoC would only be reached during a grid
outage.
The
Shutdown SoC
setting also determines the lowest reading (one LED on) of battery indicator display on the
front panel of the SP PRO.
