Battery-Inverter Matching at 58% share of blocks included: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of blocks included to 58%, then walk the calculation through step by step. Estimate the cost of pairing battery blocks with inverters across a microgrid or distributed energy project, so teams can size matched-block cost, compare scope, or decide whether it is material to the quote.

The inputs for this scenario

  • Battery and inverter blocks: 100 blocks (held at the documented default)
  • Cost per matched block: 45 $ / block (held at the documented default)
  • Share of blocks included: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed integration and controls cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable battery-inverter matching cost = battery and inverter blocks × cost per matched block × share of blocks included.
  • Total battery-inverter matching cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per matched block works out to 28.6 $ / piece at these inputs.
  • Variable battery-inverter matching cost works out to 2,610 $ at these inputs.
  • Fixed integration and controls cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of blocks included sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of blocks included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a uniform cost per matched block; differences in cell chemistry, inverter rating, or firmware complexity between blocks are averaged out, so use a representative per-block cost.
