Need one to run 24/7. Load would be minimal, maybe 50-75w max. I know I can get a Chinese, but concerned as I wont be around Monday thru Thursdays to keep an eye on it. Need it for a small load at my camp, (see here: http://k4kmg.com), during the week when I'm away. Prefer not to spend a bundle!
Any thoughts?

Thanks
Tom

    Would a small, purpose built 12 v system be better (cheaper?) for those security cams rather than a 48v inverter?

    Good quality 300 Watt 24 Volt Samlex http://www.solar-electric.com/inverters-controllers-accessories/inverters/sasiwain1/samlex-pst-series-pure-sine-wave-inverters/sa300wa24vos.html

    If you're sure that's what you want.

    Thanks but I've already called NAS about this one. From the description:
    'If you plan to use devices for extended periods, you may want to consider the more efficient SA series of inverters from Samlex. '

    Price is right but they said heat might be an issue if it's on 24/7. Unfortunately the SA series is quite a bit more expensive.

    At less than 100 Watts load? I doubt it.

    And if you buy a Chinese wonder what guarantee will you get that it won't just fry instantly? None.

    Check out Exeltech pure sinewave inverters. Just make sure that you get the correct voltage. They make from 12 - 108 volts input. Very high quality and NAWS sells them, although I have purchased several on Ebay for a very good price. They also make a 125 watt version that would probably work for you. I have purchased them in the past for $75 or so.

    Good luck and let us know how it works out.
    12K asst panels charging through Midnite Classic 150's, powering Exeltechs and Outback VFX-3648 inverter at 12 and 48 volts.  2080 AH @ 48 VDC of Panasonic Stationary batteries (2 strings of 1040 AH each) purchased for slightly over scrap, installed August 2013.  Outback PSX-240X for 220 volt duties.  No genny usage since 2014.

    Inverters with remote on/off switches are very nice (I don't remember any of the Exeltech having remote on/off). It is a pain to use a relay. Although, if you use a large DC rated circuit breaker (instead of a fuse)--That is a pretty easy way to turn the inverters on/off.

    I think only 600watt and above.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.
