Cobra 1575 1500 watt inverter: Any guidance?
1252314
On my 1575, I noticed that the wattage doesn't show unless you put a heavy load on it. I think that maybe normal with this unit. I also noticed that the output voltage is low unless you put a heavy load on it. Output starts at 86 volts with no load and goes to 124 volts with 1000 watts load. The voltage was in the 90's with anything less than 250 watts. Anyone else experience this? The biggest problem for me is the low voltage alarm which kicks in at 11.6 volts... way too soon. The manual states 10.5v which would be more reasonable. I called Cobra this morning and they were really no help. The tech guy lazily said 11.5v alarm was normal. He didn't have much response when I told him the manual states 10.5v. After a long pause, I said "so the manual is wrong?"... he said "yes". Oh well, I'm returning mine.. and based on the tech guys response, I'm afraid to try another one.

I only wish I knew.It just runs on a regular current....I do not know what an inverter is. I sure do like mine under my desk.

From My experience the "30 amp" Sunforce controller is not robust enough for the output of the 4 158 Watt panels. I had to buy an Outback controller. Because there does not seem to be a good inexpensive controller in the realm of 30 to 60 amps out there. You could get 2 controllers and split the panels. A little more info on the Sunforce controller, they die quietly for the most part, and there are some Websites out there that may have figured out a way to beef up the controller. The world of solar is very seductive and can suck your wallet dry in minutes... or months. If you are just trying to supplement your home use, and do not need power at night, you should consider getting a 500 watt grid tie inverter. During the day the inverter will produce power, and run reduce the speed of the electric meter, if it makes more than you are using it will run the meter backwards.They plug right into the house, and they have island protection, meaning that if the power goes out the inverter stop. Amazon has them,

calculate amp x volts for your compter up to 900 watts inverter capacity good luck

I have a 1600 watt inverter connected, also with an inline fuse. It all works fine, my only concern is the cables get quite warm, but it has been connected for about a year now just fine. Makesure you use an inline fuse with proper watt fuse.

I use a 1000 watt inverter connected to the battery with jumper cables. With the engine of the vehicle running it works perfectly.

The battery bank is the power supply so have good deep cycle batterys a lot of amps are needed to run this inverter. The 1500 watts is close to 15 amps of current for as long as the batterys can supply the current. The inverter supplys peak amps to start things up but for a short time only. You must always know the watts/amps of the load you run with the inverter as not to over load it or a fuse will blow and it will over heat. Inverters or made mostly for short useage as they eat up a battery fast. The surge power is only on start up as fast as you cut it on or the load pulls current then it normal power after that.

Many steps are needed! Many videos on youtube show you proper set-ups. These put out DC voltage (2 wire) you'll need a DC Voltage controller. From the controller to Battery! If you want AC I go a differant rout. these don't really put out enough power to bother with an AC power inverter... hope this helps.Murf.

Make sure your continuous load is under 3000 watts since this inverter is rated at that.

I have read somewhere you should connect the inverter to the battery. Because of the potential load you are pulling could exceed the charge controller. I am just passing on what i read just got my panels will be installing them soon

I used the terminal blocks off the old inverter that I was replacing . You should be able to purchase grounding lugs with 2/0 connections and 1/4" or 5/16" size holes to convert over. I am very happy with the inverter. It is able to do what it says. Just got back from my camp over the weekend that is off grid, just solar 12V. My friends wife ran a blender to make a drink while we had all are lights and a tv with a dish setup all at once. We wanted to see if it would all run and it did . Had others that do not come close. Good luck

You will need a positive and negative cable of appropriate length between the Battery and the inverter. Size of cable should be able to run maximum output at the incerter(6 gage would suffice. Also include on the positive cable(within 6 inches of the positive battery terminal) a 60 amp fuse or dc rated breaker to protect the wire between the battery and the inverter. That will get you going and protected. Plug in your ac devices and go.

What i have ran is zero gauge wire,(yes, it's huge but it carries all the current the inverter can produce) a raptor ranl1502 150 amp anl fuse, with a DB Link anlfh01 0-gauge anl fuse holder. You will also need a hammer crimper and wire lugs for the wire ends to connect to the inverter. I use an optima battery with top and side post and crimped lugs on the wires to connect to the side post on it as well. You can get the DB Link pw0r50z 0 awg positive wire on amazon for $74 for 50 feet right now. Otherwise you're looking at around $250 for other brands.

That option works on my 2000 watt inverter but I do not use it. So many new appliances will not work unless they have power available all the time to run the internal controllers. I noticed however that if I turned on a load that it would not start right away you had to wait until the inverter decided it was time to start. Because of my experience on the 2000 watt inverter it was never tried on the 3000 watt inverter.

Not to power a single 2000 watt load. You cannot connect the outputs. But you can tie two inverters in parallel to the same battery bank to have two separate 1000watt, 120volt sources.

I used a Xantrex brand 1000W modified sine wave unit and it works just fine. I used #2 battery cables about 3ft long each that I custom made between the battery and the inverter. I got #2 welding cable from a local hardware supply store and the cable lugs from an electrical wholesale supply house. I used solder paste on the wire and using a propane torch and plumbing solder I soldered the copper cable into the cable lugs. I also installed a 100A fuse on the 12V side for safety. For the battery I used a Trojan 27TMX deep cycle battery. I you need photos of my setup I can send you them.
