Appendix B - System Behavior Example

In this example the StorEdge system uses maximize self-consumption mode with zero export limit. The inverter is connected to

L1 and L2 in a split phase home. It supplies loads connected to L1 and to L2 load and exports excess PV power to the grid.

The produced PV power is 2kW, and there is 2kW load on L1 and a 1kW load on L2. The StorEdge system supplies 3kW to the

loads – including 1kW from the battery - and exports 0kW to the grid.

The meter measures 4.16A on L1 to the grid and senses 120VAC with positive phase between L1 and Neutral, therefore the

power import on L1 is 4.16A x 120V = 0.5kW. On L2 the meter measures also 4.16A from the grid and senses 120VAC with

negative phase between L2 and Neutral, therefore the power export on L2 is 4.16A x 120V = 0.5kW. Total export power is 0.5kW

- 0.5kW = 0kW. Due to the load imbalance between L1 and L2 there is an 8.33A current on the neutral wire between the home

and utility transformer.
