The data shown on inverter display is inconsistent with the actual situation of B12Plus2000-1

Model

BPlus series pure sine wave inverter 2000W 12VDC 120VAC


Description

1. DC input voltage 11.3V, input current 0.2167A. But the data shown on inverter display is inconsistent with the actual situation. As shown in figure 1, 2.
2. Theoretically, the machine's output voltage is 110V , but shown on display is around 220V, and its actual output is  0V.
3. S-C failure occurs after starting up.


Analysis of the possibility of the cause
DC voltage and current value does not reach the standard value to start up the machine, so the display shows wrong information.


Solutions and steps

1. Turn up DC voltage and input current;
2. Connect good battery to inverter.


 


Note: 

A. If DC input voltage is not enough to start up the inverter, its display works normally, but the machine has no output voltage and power, as shown in figure 3;
B. The display shows wrong information if the DC current is insufficient;
C. 12V inverter, starting voltage≥13V, starting current ≥5A.
