DC voltage from 24V to 27V the 24VDC inverter broke down after starting up
BP series pure sine wave inverter 3000W 24VDC 220VAC
1. There is a small power supply for inverter. After testing voltage from 24V to 27V, the inverter broke down after starting up;
2. There is no load at the output;
3. The power supply output voltage is 27V, its output current is 1A and can be adjusted to 2.5A at the maximum.
Analysis of the possibility of the cause
DC output current is too small. Starting current shall be over 5A and starting voltage shall be over 25V while starting up.
Solutions and steps
Replace with more powerful battery to assure the output current reach more than 5A.
Comment: The white machine at the right side is customer's small power supply.
