Modeling multiple inverters

Last Updated: Jul 21, 2016 04:24PM MDT

How do I model with multiple numbers of inverters, different inverters for solar PV and battery?


The way to do it is to specify the PV array as being connected to the AC bus rather than the DC bus.  Then what HOMER models as the PV array is actually the PV array and its dedicated inverter.  What HOMER models as the inverter is the "other" inverter, which connects the battery bank to the AC bus.

To do this, you'll have to make sure that the power ratings you indicate in the PV Inputs window reflect the AC power output of the PV-inverter subsystem, and that the costs include the cost of the inverter.
