The default charge settings should be considered as safe for most battery
types. Exact charging parameters should be confirmed with the battery
supplier.
Max. Charge Current
is the maximum charge current that the inverter will allow to
the batteries under any circumstances (including all external charge currents) at any
charge stage. This is expressed as a percentage of the battery capacity. For example
if the battery capacity is 900 amp hours and the battery manufacturer suggests a
maximum charge current of 10% of capacity then you would set this figure at 10% and
the maximum charge current limit would be set at 90 amps. If, in this case there is 40 A
of solar charge current, the inverter will add to this a maximum of 50 A of charge into the
battery.
Initial Return Voltage
is the voltage level at which the charge cycle will return to the
beginning, or Initial, stage of the charge process. The battery voltage must remain at
or below this level for 2 minutes to switch to Initial. This ensures that short term loads
do not prematurely cause the charger to reset to Initial. The setting will turn RED when
it exceeds the lowest float voltage (either Float or Long term Float) minus 5% for Lead
Acid or 2% for Lithium or Custom Battery Types. Care should be taken when setting in
the RED region to ensure the Float or Long term Float voltages cannot trigger the Initial
return under the maximum battery temperature conditions.
Initial Return SoC
The Charge cycle will also revert to the INITIAL stage when the
battery SoC drops below this setting. This is to ensure the charger will still initialise
under light battery loads that do not take the battery voltage below the Initial return
voltage.
Charger Settings
This tab shows all the settings relating to the DC voltages and currents used in the battery recharge stages.
The normal charge cycle involves a four stage charge – Initial, Bulk, Absorption and Float– while periodically
it is necessary to go one stage further, for the performance and longevity of the battery bank, to the Equalise
stage. We will describe each of these stages as we progress.
