I am connecting a 1000w Cobra Power inverter to a deep cycle marine battery that will be used to run small appliances while camping. How do I properly connect the inline circut breaker for maximum safety?

Deep cycle is typically for long duration loads like lights or a troling motor but not very high starting currents. Unless marked, an RV battery is a combination starting running battery. It may have a higher starting current than the deep cycle, but not as long of a run time.

all the jump starts i have seen have a deep cycle battery that is sealed - i would not run something like an air compressor motor with low voltage - it can be discharged almost flat , but do not leave it long before charging back up - low voltage =high amps on motors

Does it work if you plug in just your smallest appliance 110W?. How about just your 600W appliance What size wire are you using to supply power to the inverter? The inverter will draw about 30 amps from the battery with your load. You need to use wires as large as a number 8 from the battery to the inverter. The length should be as short as possible but could be 20 ft away. My inverter is a 2000 Watt continous and I use welding cable size 0 at about 3ft max between the battery and the inverter.

Automotive batteries are designed for a quick draw of amperage (when starting) and then get constantly recharged using the alternator when driving. If you are using an auto battery for inversion, it will drain much quicker. Depending on how/where you are using it, you could charge the battery when a meter shows a voltage drop. Better recommendation would be to use a marine battery, which is a deep cycle battery. Deep cycle batteries last much longer between charges, as they are designed to have a constant draw (trolling motors, etc.).

Hi
Assuming there is nothing wrong with the inverter or heater.
You need to check the voltage on the input clamps of the inverter (+ & - connections on the back of the inverter) when going under load, if the voltage is going under 12 volts as it is applying power to the heater there is a connection or volt drop issue.
The inverter is capable of drawing up to 190amps from the battery this can cause damage to the battery.
It is very rare for an inverter of this size to be used on 12 volts.
There are a long list of calculations which I am not going to bore you with, but for this inverter to run on a 12 volt battery system and not cause unesesary damage to the batteries you would need 8 x 120AH deep cycle batteries.

Yes, just be sure connections are heavy enough wire, and obviously the inverter uses 12 vdc input. Hook jumper wires positive to positive, negative to negative, on all 12 volt batteries. Deep cycle batteries will work better than car batteries. Just remember, when re-charging them, that they last longer when charged slowly, so don't use a high amp setting on charger and to monitor them closely, and do it in a well ventilated area, away from any ignition sources.

If your appliance draws over 300W or if your 12 v battery charge is low you will get a loud beep warning. Do you get the same beep with a low current appliance like a lamp? Make sure your battery has a good charge.

Some appliances have huge draw at start up even though they are rated under 300w your inverter may not be able to start.

Also some electric motors don't like modified sign wave inverters.
What are you trying to run and what is its rated watts?

I had my inverter beep when I had it connected via a cigarette lighter plug but when I used a connection straight to the battery it worked fine.
I was running a 500w grinder on a 1000w el cheepo inverter.

Automotive batteries are usually adequate for small inverters, (< 500 Watts). When used in a car, we suggest you run the vehicle of your engine occasionally while operating your inverter. If you use the inverter while the engine is off, you should start the engine regularly and let it run to charge the battery. Deep Cycle (marine) batteries are best for larger inverters as they are designed for several hundred charge/discharge cycles. (Automotive batteries wear out much more quickly after heavy discharge).
