3 year old 24VDC 3000W Multiplus shutdown with low battery light flashing (all other LEDs extinguished). Confirmed there is 28VDC at the DC input to the Multiplus. Battery connections are very clean. System was under a 100W load when it shutdown. VRM shows no drop in DC voltage prior to shutdown. Removed the front cover and discovered small ants inside the Multiplus. Has anyone every seen anything like this? Could the ants have caused the malfunction? Appreciate any thoughts. Thank you.
