A properly sized PHI battery bank will prevent over-discharge, over-charge and provide the required amount of energy and power to meet your electrical loads and overall project objectives. WebAll we have to do is find the current through the controller by using power = voltage x current. Take the power produced by the solar panels and divide by the voltage of the batteries. Example: A solar array is producing 1 kw and charging a battery bank of 24V. The controller size is then 1000/24 = 41.67 amps. sifton funeral home st.thomas
