It is common for those with new solar configurations to worry about whether or not the

**Example**: Let's assume the same 14.0v alternator output and solar contribution that pushes up Vbatt by 0.3V
* I=... v-**13.0v**)/0.020mR = 1.0v/0.020mR = 50A without solar
* I=V/R = (14v-**13.3v**)/0.020mR = 0.7v/0.020mR = 35A with solar
