Removes charging constraints for min efficiency to handle grid outage cases. Removes ac losses (such as wiring) from batt to grid to make sure batt to grid matches AC  power. Add DC DC efficency to batt power AC for full representation of convention where this number represents hypothetical grid charging when charging from PV. Update test code to better handle efficiencies

…tt. Solves issue with battery energy charged from system summary metrics being less than 100%

…iciency

Update the powerflow convention. Using actual efficiency here would result in even higher round trip efficiencies. Also fix a possible infinity in the tests

Doing this on the DC side allows grid to batt to match inverter ac output
