low-input voltage warnings and shutdowns. This is due to the DC voltage
drop in the cables from the battery to the inverter.
The longer and narrower the cables, the greater the voltage drops.
WARNING!
DC wiring terminations.
Ensure all the DC connections and terminations are
secure and tight. Loose connection can cause
overheating and fire.
The following table recommends the cable size for optimum inverter
performance.
