Installed 20" 120w and now want additional 32" 180w will i need a two leg harness @ 300w or am i pushing it? Should i just run two single leg instead.

It depends on the fuse you put in line - but there is already over 20 amps of draw. (Kind of pushing it already) probably better with 2

you should be okay running two Bars on one harness just have the proper fues for the wiring harness everything should be able to handle it but it's cutting it close

Always better to play it safe. Run two seperate legs, you dont want to have all lights out because of a blown fuse. A little more hassal ,but worth it. I know this from expirience.

There are only two wire leads at the end.....depending on your needed voltage output to power the lights , you could splice one wire into two units, but working with 12 volts, thats not going to be very bright....I would go with 2 harnesses...... good luck!

In terms of the wattage, I would definetely recommend going higher than the rated requirement by around 1.5x (so technically 2250W+ if available). The ratings are never an exact number (or for constant pull of power-just a peak output) and even if they were it would be running right to the edge of its potential in your case, which would not likely end well.

Keep the length of the 16AWG wires as short as possible and use the larger wire for the rest of the run it will work fine you don't have to change the 16AWG all the way to the socket. The resistance is dependent not only on the cross sectional dimension of the wire but the length of the run

The needed power supply is dependent on how much you are sending signal too. For example, I'm using this for a 15' strand of RGB LED rope, that uses 30 Watts at 12V, so the 12V 2.5A power supply I'm using JUST does what I need. If I tried to do a longer strand, I'd have problems because it would require more amperage. This unit has a max output rating of 8A per channel (24A total). You need a little basic electrical understanding to figure out what is suitable for your needs. Watts = Volts x Amperage

This might be too much light. You may want to buy a 3w as well so you can see which one give you the light you want.

I switched from the lamps to the LED units and used the old transformer from the initial installation. Obvious much larger than necessary since these LED's are rated at 2 watts. A smaller transformer of 40 watts will work fine with plenty of reserve to add more fixtures.

60 watt on top and small nite light style in leg but it came with both already installed

You need either that kit or an equivalent, as the inverter does not come with connection equipment. The kit includes the cables and a (very necessary for safety) fuse. If you are replacing an existing inverter and already have cables, then the kit would not be necessary (unless this is a much larger unit and your cables are not properly sized). for 12V 3000W you will need 0000 cable size.

I have 5 of these and did not install a fuse. I have discovered that for practicle installs >10 feet of wire, you need 6ga or double 10ga to reduce voltage loss. This is VERY important if setting up an MPPT system. Its still important for PWM. You can never have wires that are too thick.

according to tigerdirect 500w is needed http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8573338&csid;=_61

Try to add 19 Ft of regular wire, see if it works. You have nothing to lose...

That will work, a 16' of 3528's draws 24 watts @ 12vdc. Just make sure that power supply is 12 vdc. If used alot then a 48 watt or 72 watt @ 12vdc would be better.

That's more then enough, you will have about 100w extra, just be aware any additional hardware besides your build will tax your psu more for future upgrades.if you have any other questions iam more then happy to help a fellow comp builder

Buy 4 of these 3 to 1 splitters (http://ecx.images-amazon.com/images/I/61TemWV9nHL._SL1500_.jpg). Connect the single side to your 12V power supply then connect 1 TSSS Data Repeater (amplifier) to each of the 3 ends of the splitter (you will need 3 amplifiers). Use the other 3 splitters to connect 1 to each amplifier. This will give you 9 plug ins for your 9 lines and you will not have any power issues. This is probably overkill, but the parts are cheap and you are better off having more available capacity than too little. TIP: To keep things clean I attached heavy duty velcro to the back of each amplifier and the 12V power supply and stuck them to the wall. Buy way more wire (http://ecx.images-amazon.com/images/I/71ekjJHHuAL._SL1500_.jpg) than you think you need and use these (http://ecx.images-amazon.com/images/I/41q%2BhzsWiQL._SL1500_.jpg) on the amplifier end of the wire and cut these in 1/2 then splice them on the light strip end (http://ecx.images-amazon.com/images/I/71j87VtkuhL._SL1500_.jpg) to make everything "plug-and-play".

You would need two LFM-20s. It makes more sense to install near the buttons for the shortest wire run if you have a power source to connect the LFM-20 to as it requires 120vac power.

the owners manual that came with the Powerpack had directions on how to install the proper fitting ( same as the charger/converter end) on a standard 30W panel, I don't have mine anymore or I'd look it up for you, Sorry.
