5 Steps for a DIY Busbar for Solar Power System

Your inverter is most likely the biggest draw on your system. Let''s say you have a 8kW inverter and a 48V battery: 8000W/48V = 166A. Your busbar needs to be able to handle 166 Amps of current. We should multiply this by the safety factor of 125%. This then becomes: 166A * 1.25 = 207A. We need a busbar that can handle a current of 207Amps. 2.
