I have the 2 t105's in my sisters garage waiting on the battery box. Decided to test them out. Wired them in series and checked them with the meter. 12.4v which I think is about 70-75%. Hooked up a 400w inverter from Walmart and got nothing. I returned it and bought a 400w peak performance inverter from advanced auto parts. Hooked it up, got nothing. The inverter works in the 12v outlet in the van. Am I buying the wrong inverters, or is there something else going on? Thanks.

Help Support Van Living Forum:
only thing i can think of is that you wired them for series correctly and took the reading from the correct posts (as evident in the 12.4v reading) but perhaps you hooked up inverter to the unused posts, on the same battery? in that case you would only be getting 6v....and the inverter will do nothing.<br><br><br>but if i read your post correctly you said that you tried them on both?? so...not sure.<br><br>the inverter should be wired to the pos terminal on one battery and neg terminal on the other<br><br>
can u post a clear pic of your battery wiring? i dont think its compatibility issue....as long as the inverter gets 10.5 to 15 volts it should make AC power. the range can vary a little by manufacturer but its close.<br><br>if you only feed it 6v...or 24v if its not rated then youll have a problem.<br><br>
<p>I connected it with the alligator clips that came with it. The batteries are connected by a battery cable my brother in law had in the garage. I think it's 4 gauge and about 6 feet long. When I tested the voltage from the batteries with the inverter hooked up it read between 1.8 and 2.5(went up and down some) Forgive my ignorance on this subject, but shouldn't it still read 12.4 ish? I hooked it up this way just to test it out, now I'm thinking I should hook it up correctly tomorrow. Does this shed any light on the issue? If not I can take a picture. Thanks.</p>
hard to explain those readings...<br><br>4 gauge or 6 gauge interconnects wont cause you a problem for a temp test like that but you would want larger cable. i would suggest 1/0 or 2/0 for interconnects since those batteries can put out 225 AH. so if you expect to be able to use that from a wattage perspective youd want thicker cables.<br><br>doubt its the issue tho.<br><br>for series, you want to run battery 1 POS to battery 2 NEG and battery 1 NEG to battery 2 POS...then, any loads or charging devices should be connected at opposite ends of the battery bank as a whole...<br><br>so load/charge would be battery 1 POS and battery 2 NEG.<br><br>see if this is how you have it hooked up. that should give you 12v at 225 AH (i think the 105's are 225).<br><br>the alligator clips are fine for a small inverter like that ( ore temp testing) but you need to make sure that they are really clamping down well.

also check the fuse on the inverter that you still have...there should be a fuse on the POS lead between bank and inverter always. those small inverters often have a fuse on board...<br><br>its possible the fuse on both inverters were blown out when connected either due to something being wired wrong...or when you hooked them up you reversed polarity or shorted out somehow...then once you recovered the unit appeared to be not working due to fuse blown<br><br>anyone else?
Now I feel like a fool for wasting your time. I only hooked 1 wire, battery 1 pos. to battery 2 neg. when I got the 12.4v reading I thought it was good to go. Even with all the reading I've done on here, some stuff just doesn't sink in. Thanks for the help, and sorry.

Even though it gave me the 12.4v readout, it wasn't working. After hooking up the 2nd cable it works. I did hook them up in a circle briefly.(I was wearing a face shield while doing this) Luckily nothing bad happened. Thanks for all the help, sometimes it's something simple.
