Yes, you’re right. When your MultiPlus-II 230V shuts down and both the ‘overload’ and ‘low battery’ LEDs are continuously lit, it indicates an issue with excess ripple voltage on the battery terminals.
This is more serious than just a pre-alarm, and here’s how to address it:
-
Power Down: Safely turn off the inverter and disconnect it from the power source. This step is essential to prevent further damage.
-
Inspect Battery Connections: Look for any loose or corroded connections that could be contributing to the issue. Ensure that all connections are clean and secure.
-
Battery Health Check: If you have the tools, measure the actual ripple voltage to confirm it’s within the safe range specified in your manual. If the batteries are old or have been under heavy use, they might be the source of the problem.
-
Load Reduction: Reduce the load on the inverter by disconnecting non-essential devices, especially those that draw a lot of power.
-
Reconnection and Testing: Once everything looks good, reconnect the inverter and monitor it closely. Check if the LEDs indicate normal operation or if the ripple alarm reappears.
-
Professional Help: If the problem persists despite these steps, it’s advisable to seek professional help. Excessive ripple voltage can be tricky to diagnose and might require specialized equipment or expertise.
This situation typically indicates a more complex issue within your power system, possibly involving the batteries or the power supply quality. It’s important to address it promptly to ensure the safety and efficiency of your system.
