Has your inverter suddenly turned red and emitted a shrill alarm sound? Don't rush to call the electrician yet! In fact, 80% of inverter alarm problems can be solved by themselves through simple troubleshooting. This article will reveal the solutions to the three most common malfunctions, helping you save unnecessary maintenance costs.
Symptom 1:
Three short alarm sounds (overvoltage in the power grid).
The screen flickering voltage value (such as 260V, higher than the normal range).
Possible reasons:
The local power grid voltage is unstable (common in rural areas).
The voltage protection threshold of the inverter is set too low.
Solution:
Test the incoming voltage with a multimeter (with a simple operation diagram attached)
Contact the power supply bureau or adjust the inverter voltage range (professional operation is required).
→ Insert product association: Our product can withstand a wide voltage range, specifically from what to what, and is suitable for areas with unstable voltage
Symptom 2:
Four short tones beep Beep Beep.... Beep beep beep
The inverter automatically stops working
Possible reasons:
The inverter is operating at too high a temperature and the casing is getting hot
Solution:
Clean the dust from the vent (with before-after comparison pictures).
Avoid direct sunlight (Suggested installation location diagram)
Our inverter is equipped with an intelligent fan cooling system and features over-temperature protection. It will pause operation when the temperature exceeds 85℃ and resume operation immediately when the temperature drops below 70℃
Symptom 3:
Inverter HAS BEEN beeping a short beEP...........
The inverter has stopped working or broken down directly
Possible reasons:
The load power exceeds the output power of the inverter itself, and it is overloaded
Solution:
Restart once after 3 seconds. If it is still overloaded, you can manually turn off the power and restart it
→ Insert product association: Our inverter has an intelligent overload prevention function. When the load exceeds the output power, it will automatically suspend operation to protect our inverter. Just wait for a moment and then restart
