I have assigned electric meter to the solar PV system, electric meter to the excess of the solar PV system production and electric meter to the CHP. I have also assigned a fuel meter to the CHP. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">When I run the simulation and go to the simulation report PS-B I find that all these meters have zeros for all the months. Also in report PS-C, there are zeros for the solar system and the CHP productions. However, when I assign the eQUEST default electric meter EM1 to the solar PV system and the default EM1 and FM1 to the CHP, I get the production of electricity in report PS-C for both the solar PV system and the CHP.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Can anybody help me out and let me know why I am getting zeros when I assign meters other than the eQUEST default meters? The files of this model are attached for your review if you have time.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thank you very much for the help.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Regards</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Ahmad</div></div></body></html>
