Quick Evaluation afore In on Introduction Quick Evaluation Before Installation This section provides you with basic information about the inverter and how to check its performance before installation Be sure to have on hand A 12 volt DC power source such as a vehicle battery Power Source The power source must provide ees T ca between 11 and 15 volts DC and be able to supply enough current to run the test load As a rough guide divide the wattage of the test load by 10 to get the current in amperes the power source must deliver Cables to connect the power source to the inverter not included The cables must be as short and thick as possible in order to reduce the voltage drop between the power source and the inverter when it is drawing current from the power source If the cable suffers an excessive voltage drop the inverter may shut down when drawing higher currents because the voltage at the inverter dropped below 10 volts 4 AWG stranded copper cable is recommended It should be no longer than four feet one and one half meters The end of the cable that connects to the inverter must have its insulation stripped off for about one half inch one and one half cm back from the end exposing the bare copper The other end of the cable which connects to the power source must be terminated with a lug or other connector that provides a secure low resistance connection For example if
