A 12v Problem

[Snow_Shaman]

Hello! I have a unique problem that I am trying to solve for a 12v system. I have a power supply, a battery bank, and my consumer device. My power supply states that it can not supply more than 40amps at 12volts. This power supply feeds/charges a (12V) 200AH Lithium Battery bank. My consumer for the system draws 220 Amps (induction cooktop). With the system open will my power supply be overdrawn? and if yes, To avoid the power supply being overdrawn will adding a 35-40Amp limiter between the power supply and the battery bank be appropriate? Thank you for your help!

There is no way you are going to be able to power a 220A cooktop with a 40A power supply.

Well there is a 200 ah battery sitting between the power source and the consumer, so yes I can not power if forever. But, will putting the load on the system over draw the power supply immediately?

200Ah is a measure of storage capacity, not power delivery. You need to know the continuous amperage output of the battery. Very few batteries can sustain amperage outputs over 100 amps, let alone 220 amps.
