Surplus Charging Simulator

Enter production and household consumption to estimate the current available for charging on each phase.

1. Choose your setup

Surplus charging supports TN one- and three-phase installations and IT one-phase installations.

Charging mode

Select the mode you want the calculation to represent.

2. Enter current by phase

Compare production and household use directly on L1, L2 and L3.

L1

0 A
0 A

L2

L3

Current is evaluated in amperes (A) on each phase. Available current from different phases is not combined.

3. Check the result

Available charging currentProduction minus household consumption equals the available surplus on each phase.Surplus from different phases is not combined.

How the values are calculated

Production0 A
Household use0 A
Available surplus0 A

Phase details

See how production and household use affect each phase.

Result makes sense?The available charging current matches the production and household consumption entered above.
Still seeing different behaviour? Continue troubleshooting surplus charging →Real installations may behave differently. Surplus charging starts only after surplus has been available for approximately 10 minutes.
