I own a Magnum MS-AE (4000W) 24VDC - 120/240VAC Inverter/Charger.
I really like it - Two thumbs up.
Do yourself a favor and hang the inverter on a Midnite Solar "E-Panel". This makes the install very neat and it integrates the overcurrent protection and wiring in a compact package.
I'll look for a photo of the installation.
