What do the lights on my Enphase IQ Battery 5P mean?
Short answer
On an Enphase IQ Battery 5P, solid or slowly pulsing green or blue means it is working normally. Solid yellow means it has stopped because it is too hot. Red flashes in pairs mean an error state, so contact your installer or Enphase Support. If it doesn't recover after a power-cut shutdown, Enphase's owner guide describes a DC-switch reset.

What does this mean?
Owner guide: turn the battery DC switch off for 30 s then on (accessible without removing cover). Support will ask for battery and gateway LED states.
What should I do first?
Record the code and current battery state before changing settings. Follow only the owner-safe reset steps in the manual.
When do I need an engineer?
Use an installer or manufacturer support route if the fault returns, involves isolation or protection, or the manual does not give an owner reset.
What to do next
If the system is hot, smoking, damaged or making unusual electrical noises, move away from it and follow the manufacturer emergency guidance.
