Why sometimes inverters can't support other kinds of batteries?
BP2000-S pure sine wave inverter
The inverter can work normally when using AGM battery. After replacing it with a lithium battery, the situation shown in the figure appears, the front-stage MOSFET bursts.
Solutions and steps
1，According to the customer's response, after replacing the lithium battery, the front MOSFET bursts. It can be judged that the voltage of the replaced lithium battery is too high that exceed the voltage range the machine can withstand, causing the front-stage MOS tube to burst.
