Why isn't my Zendure battery charging?
Short answer
A solid yellow left light on a Zendure Hyper 2000 means the battery is low and not charging. Zendure suggests checking solar and AC cables, unplugging everything for 30 seconds and reconnecting, and confirming the grid and panels are working. If a red light appears, read the fault in the Zendure app and contact support. Checked 24 September 2026.

What does this mean?
Blinking left yellow: reseat Hyper on battery (only as supplied, unplugged)
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.
