I am looking for a company which imports directly, to supply a complete inverter unit with the following,

A charger correctly rated for the size battery (preferably at least 10% of the battery capacity),
A battery mounted in an enclosure,
A square wave 800 watt and 1500 watt inverter,
A pure sine wave 800 watt and 1500 watt inverter.

The units must be supplied complete on wheels with a 15 amp plug top.
