<BR>
The one meter hook up always seems confusing to me. I'm still confused. Do we have the AC IN at both the bottom left and top right? To me it seems that the AC OUT from the inverter would go to the upper left and the protected loads panel would be fed from the bottom left. <BR>
<BR>
I've never used this method, but would like to use it instead of the two meter method.<BR>
<BR>
Thanks,<BR>

this set up allows grid tied selling and battery saved energy selling to be metered while subtracting energy used to charge batteries and subtracting any power needed to run the inverter.<BR>
<BR>
hope this helps.<BR>
