I've had one of these inverters for at least 4 years, and am now buying another. I use it fairly hard, for a mobile power source for construction mainly. My first one is in for repair, as the extremely dusty location it was in finely took its toll. It worked great for power tools, except for my compressor which it wouldn't run properly (it would turn over, but really slowly). It does make a bit of noise on stereo's, as it is not a "true sine" inverter, so I wouldn't get this to run delicate electronics. The tiny on off switch and dip switches would be the main drawbacks to this inverter, in my eyes. Its a good product for its price range. (currently ~$650, it cost me ~$900 4+ years ago...)

I purchased the Tripp Lite APS2448UL as a heavy duty computer battery backup. Shortly after I made all the connections, I heard a small pop and saw a puff of smoke come up from the unit but saw no change in the operation of the unit. Of course I immediately call the Tripp Lite customer service department and told them what happened. The person on the phone was intent on trying to figure out the problem. They had me do a series of tests and when everything checked out ok, he gave me a incident number and told me to call if anything else happened. About 15 days later the unit stopped working and all my batteries were drained. I called back and they promptly send me a new unit. Had me return the old one to them in the box that the new one came in. They sent a pre-paid shipping label. This time, there was no popping sound but the unit again died in a few days and my batteries were drained. After spending a long time on the phone, trying to figure out what was going wrong, we finally discovered that the 2 sets of dip switches read from right to left instead of left to right. In other words, Block A is on the right and Block B is on the left. Also the dip switches themselves read from right to left. Switch 1 is on the far right and switch 4 is on the far left. After charging my batteries up with a separate charger and re-setting my dip switches, everything is working great now. I am convinced that the first unit that I had was ok, just had the switches set backwards. I don't know about the popping and smoke. My complaint is that the instruction manual should have been clear on the reverse order of the switches. On the other hand, the response from Tripp Lite tech support was top-notch.

Whether you need a backup power supply for a telephone switch, or are building an off grid solar power system the APS 2448 is a lot of product for the money.

Most importantly: It does what it says. Produces power from 48v of lead acid and charges them when you give it power. Smoothly.

Cons: The controls and dip switches are small. so are the display LEDs. The mounting forks are plastic, and you have to mount it horizontally (like its pictured), and not upright on its side.

I really like the part that you can adjust the sensitivity so the inverter only comes on when the refrigerator wants to start and doesn't have to be on all the time. Really saves on batteries. I bought mine to keep the furnace, refrigerator and freezers working during the power outages and so far it has worked very well for over a year. It is very easy to connect up and has been the best back up power inverter I have had to keep the appliances running. Being modified sine wave though, it doesn't work well on devices with CPU's and such like some phones, clock radios, cable boxes and DVD players so I have a nice small pure sine wave unit for them.
