The MCS self-consumption calculations in the Performance task don't work for my project - why?

The MCS self-consumption calculatorcalculations won’t work for projects with an annual generation greater than 6000 kWh or with battery storage over 15.1kWh. For these situations, we recommend using the Easy PV consumption task to determinegenerate accurate system projections and then ensure you select the solarEasy self-consumptionPV figure.calculations on the financial task.
