The solar system does not work correctly– possible causes and remedies
Attention! Batteries contain large amounts of energies. In case of short-circuit, these energy quantities can be released in a
short time and cause fire at the point of the short circuit due to high heat generation.
Symptom
Cause
Remedies

Defective or loose connection box cable
Wrong polarity of connection cable
Fuse defective
Precharge battery
Fasten connection cable
Connect cable with the correct polarity
Rectify the cause, replace fuse
All LEDs off, display shows "STANDBY"
no sufficient solar power
Solar cable defective
Check solar panels
Eliminate interruption or short circuit
Display shows 12V system instead of 24V
