<p style="margin: 0px;">I have had a Samlex 600W pure sine wave inverter. Going on 2 years now. My needs are small, 24inch led tv with dvd player, boombox, sat. radio ect. 2 agm lifeline batteries, and a Honda 2000w genny. NO MICROWAVE. Fine setup.</p><p style="margin: 0px;">Go to batterystuff.com. Knowledgeable folks there. Also, on their web page, there is reading to walk you tru all things 12v elec. If ya need it. If i were to go any higher on the inverter, i would go to AM solar in Oregon. AM also has lots of info on their website. Lots of vans do not have the pure sine wave. Works fine for them. If you have a computer, newer tv, or other newer electronics, i would go the pure sine wave route. Have heard of to many folks that run into problems by not having pure sine wave. Guess i go by the ol saying, never to much power(batteries) and as big inverter as possible. Then if you are like me, and drive a van, weight and space enter to this also. </p><p style="margin: 0px;">If any questions, ask. Lots of people here with lots of experience.</p><p style="margin: 0px;">Good luck, Roy</p>
