  The overload LED might stay on for several reasons. First, your battery voltage may be below 10V; in this case, recharge or replace the battery. Second, the equipment you are operating might be drawing too much power; consider using a higher capacity inverter or discontinuing use of the equipment. Third, the inverter may be too hot (thermal shutdown mode); allow it to cool, check for adequate ventilation, and reduce the load to the rated continuous power output. Finally, the unit may be defective, in which case you should consult the warranty.

Why is the low battery alarm on all the time on my PowerBright Inverter?

  The low battery alarm might be constantly on due to several reasons. It could be that the input voltage is below 10V; maintain the input voltage above 10V to ensure proper regulation. Alternatively, the battery condition might be poor or weak, requiring you to recharge or replace it. Also, inadequate power being delivered to the inverter or excessive voltage drop could be the issue; use a lower gauge wire and keep the wire length as short as possible.
