How to Connect Parallel Batteries to Inverter

Question

Question:

Hi, I have 2 12 volt batteries connected in parallel and wondering if you can pull power from both batteries or should everything be connected to one battery? I am adding an inverter and was thinking about hooking it to the second battery that the parallel wires are connected. Thanks

When connecting something like the Go Power Industrial Pure Sine Wave Inverter - GFCI - 2,000 Watt - 12V
# 34278156 to batteries wired in parallel you'll need to connect to both batteries. You'll run a wire that splits and goes from the positive terminal on the inverter to both positive terminals on the batteries and the same on the negative terminals. You won't be able to just connect to a single battery in this type of installation.
