Battery Replacement Cost

In the spreadsheet the Battery Replacement line item is zero.  Where in SAM do I change that to actual dollar amounts.

Hello,

For configurations with battery storage, you can set the battery replacement cost in $/kWhdc of battery capacity on the Operating Costs input page.

Best regards,
Paul.

so after doing that it puts in it's cost which is 1/4 the actual cost. Can I enter the actual cost anywhere?

Hello,

The battery replacement cost on the Operating Costs input page is in $/kWhdc of battery storage capacity, which is shown at the top of the "Battery" column on that page.

For example, for this residential battery, the battery replacement cost would be 434 $/kWhdc * 12.5 kWh dc = $54,300 in Year 1 dollars. SAM applies the inflation rate from the Financial Parameters page to calculate the cost in the replacement year.

 

Best regards,

And where do I input the necessary Inverters for the batteries?

Hello,

For a DC-connected battery coupled to a PV system, the inverter on the Inverter page converts DC power from both the battery and PV array to AC power.

For an AC-coupled battery, the DC to AC conversion efficiency input on the Battery Cell and System page (under "Power Converters") accounts for conversion losses in the inverter.

Best regards,
Paul.
