<p class="MsoNormal"><span lang="EN-US">I am trying to simulate a PV system with battery storage but I cant seem to make It work. I am using type103a PV array, type 48d inverter/regulator and type47d battery. I have tried many modifications and sizes of the
PV and battery, but I keep getting the following error from the inverter component:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I have connected the battery’s “total voltage” output to the “Battery Voltage” input of the regulator/inverter (input # 4). The default value of Input # 4 is set to 0, so I tried initializing it with other positive values,
but when I do that I get a message for “Invalid floating point operation “ and an “unexpected error” which will make the TRNSYS to abort.
