Why won't my GoodWe Lynx battery charge in winter?
Short answer
A GoodWe Lynx Home F G2 battery raises 'Low Charging Temperature' when it's too cold to charge safely, which is common in unheated garages in winter. It resumes once the battery warms up. 'High Cell Temperature' means it is too hot or near a boiler or heater. If either keeps happening, ask your installer whether the battery should be moved.

What does this mean?
Manual remedy: power off and wait for temperature to recover, then power on (installer-guided).
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.
