Why Your Inverter Battery Gets Hot: Identifying and Fixing Issues

Experiencing your inverter battery getting hot can be a cause for concern. It's crucial to understand why this happens, as excessive heating can indicate potential issues affecting the battery's performance and lifespan. In extreme cases, it can even lead to hazardous situations. Here, we delve into the common reasons behind an inverter battery heating up and how Okaya addresses these issues.

Common Reasons for Inverter Battery Heating:

Incorrect Battery Selection Switch Setting:

•    Every inverter has a battery selection switch, typically located on its backside. This switch allows you to set the type of battery connected to the inverter.

•    If the wrong selection is made, it can lead to the inverter battery overheating. It's crucial to ensure that this switch is correctly set according to the battery type you are using.

Misconfigured Charging Current Jumper:

•    Another feature often found on the backside of an inverter is the charging current jumper. This should be selected based on the capacity of your battery.

•    Incorrect configuration of this jumper can result in the inverter battery getting hot. Make sure it aligns with your battery’s capacity to prevent overheating.
