Yes but leds would be a better choice since they are more efficient.

I realize that the math says it inefficient but has anyone actually tried to run anything but LEDs and off road lights on a battery system. I can run 2 TVs, an Xbox, and at least 8 75 watt fluorescent lights. I can run these all off and on for over 12 hours before I have to start my generator to charge the batteries. And the batteries are all really bad because I quick charge them all at 30 amp and they are all deep cycles. I can't quite figure out why that same settup with 6 good batteries won't power 900 watts of lights for 4 or 5 hours. If anyone has actually tried it let me know what you found out.

I ran 100 watt hps lights off a battery/inverter system before I switched to a quiet genny. It works fine but there are some tricks to being successful. First your 150 watt hps bulb runs on about 150 watts but the ballast that powers/regulates the bulb uses from about 175-450 watts depending on the type of ballast and whether the bulb has warmed up or not. Another issue is relighting a bulb after the batteries have run down some and inverter output voltage has dropped.
That all said six good group 29 batteries should run [6] 150 watt hpf HPS lights for 5 hours without a problem. I would recommend that you don't kill the lights in the last hour or so since they may be hard to relight.

Ok thanks. Sounds like it might work if I set everything up right. I will be using the exonolight 150 watters. Using the ones with capacitors should help a lot too right. Will it help to run 24 volt instead of 12?

I think your inverter will probably be 12 volt d/c >120 volt a/c.

The one I use now is but If everything works out on my cabin battery system I'm going to hook a permanent system up in my boat. Just wondered if 24 volts would be easier on everything with less amps.

About the only thing I can think of would be that you could use smaller wire from batteries to inverter-nothing else would change.

How many total watts of invertor will be required for each 150 HPS econo with CAPS?

They will start at around 2 amps w/cap and run on about 1.5 amps w/cap. As for an inverter I prefer one that is rated for about 2X the load you plan on running.

What about splitting the lights off on 2 invertors? Say (2) 750watt invertors?

Should work ok.
