Navigating to the Battery System Design Page
From the Design page, click on the blue “System Designer” icon located on the top left of the screen, or click on the sub-menu icon the Design tab.
Battery Discharge Mode
Back up Only
The battery will be kept fully charged, and only discharge when there is a grid outage.
Modelling is based on the 'Grid availability' factor in the De-rating section, where you can specify the percentage of time the grid is available
Minimise Tariff
The battery will only discharge during Peak and Shoulder tariff periods.
Self-Consume
The battery will discharge at any time to maximise self-consumption and minimise use of grid energy.
This will result in the maximum charge-discharge cycling of the battery
Battery Settings
Battery Nominal Capacity. This is the battery module nominal capacity x battery quantity. It doesn’t take into account the set Depth of Discharge.
Quantity - the number of battery units connected in total. This value is pre-set to match the battery inverter’s maximum voltage but can be reduced.
Depth of Discharge - This defaults to the maximum DoD defined in the battery data sheet, but can be adjusted according to how you intend to program the inverter.
Warranty Lifetime – you can specify the number of years that the battery system will be covered under warranty from the manufacturer. This value must be set based on the warranty information provided in the data specification sheet from the supplier/manufacturer.
Warranty Cycle life - Warrantied cycle life can be provided for batteries where the warranty is provided for a particular cycle life limit eg. 4000 cycles
Peak Shaving Threshold. Use this only if the battery inverter will be programmed for Peak Shaving / Reduction to reduce peak demand tariff charges. This is the peak load (consumption) power level at which battery discharge will begin. That is, the battery will not discharge until that power level is reached.
Prioritise Charge Over Loads - prioritises using solar energy to charge the battery over supplying the load, up until the State of Charge level specified. If left at 0/unset, loads are always prioritised before any remainder is directed to battery charging.
To view the effects of these control set points on the system, go to the Reports page, scroll down to the Average Daily Performance chart, and select the ‘Week’ view.
Charge battery from grid and export battery to grid.
