WZRELB Reliable 1500W Full Power High Frequency Pure Sine Wave Solar Power Inverter Off Grid 48VDC to 120VAC Voltage Converter Home Solar Generator(Black)

Q: Can I pull 30 amps (3600 watts) from the hardwired terminal block on the 4000w/48v model?

I think you can ( I assume you are talking about 30A@115VAC). Just use proper gauge wires for this. Another question is can you deliver 75A@48V to the unit ????

Q: How much amp is the inverter ?

If you mean the 12 volt current, it needs about 333 amps of 12 volts DC to supply the full rated output. To hook this to 12 volt power you will need at least 3/0 cables for up to a 40 foot run. If your run between the batteries and inverter is longer than that you'll need 4/0 cables. I suspect that some of the people who are not getting the rated power out of this inverter are not using sufficiently large 12 volt cables.

Q: Why is my inverter sucking up the volts out of the batteries and shutting down

One reason, because you have a voltage drop on your cables (between batteries and inverter) that you do not count. So, min voltage measured at inverter 12V input should be NOT LESS than 11V. Another reason - you do not have enough battery bank capacitance to keep voltage on inverter side above 11V. Inverter has efficiency around 85-90%. So, to get your system work say using 1000W you need to deliver to inverter 1176W ( 1176W/11V = 107A continues current). Add voltage drop on cables and you will have requirements for your batteries.
