Here at Solarpanel.ca we have found that off-grid people such as ourselves require both reliability and quality in an Inverter.  The very same reason you need a good heart to keep your body working.  That's why we recommend two Inverter types "Magnum and "Outback".  Both produce a very good sinewave electricity that is good not only to power your drill, but for your high sensitive electronics such as plasma or LCD TV's, laser printers, computers, bread makers, etc. Please contact us for pricing on any Inverter or Inverter E-Panel, or Outback Flexware system. Below are pictures and specifications on each.
