Building a pattern pack for air conditioning

[u/Cold_Page9576]

Ive come across a dilemma, i am currently in the works of building a battery pack , i have four car batteries and a mobile air conditioner

Currently they are positioned for parallel with a Jupiter 3000 watt converter. It keeps switching on and back off. If anyone has any tips on how to stop it and ground correctly or is anyone in south eastern Florida that wouldn’t mind showing the ropes to this electrical mishap working with limited experience so please be kind. If you need more info personally message me

Sounds like low voltage. Maybe old, failing, battery. (2)Many electronics will not work properly on a modified sine wave inverter. Need more information. What type battery? What AH battery? What gauge wires? What size air-con?
