Solar Inverter Circuit design for manufacture

Budget $250 - $750 AUD
Bids 13
Average Bid $1077

Design a solar inverter circuit with MPPT.
Unit will be connected inline between wall out and appliance. Mains AC power and output power is 240Vac.
Unit will provide a switch-able uninterruptable power supply between mains power to solar inverter power and reverse.
Once MPPT/inverter senses 500W of available power or more it will then switch over to AC power coming from inverter, once solar power falls below 500w it will then switch back to mains power.
Inverter to use pulse width modulation synced to mains power so that switching is also synchronised.
Solar AC when in use has to be totally isolated from mains power.
Front display LED to show if mains power or solar power in use.
- show daily consumption of appliance from mains power and solar power. resetting daily.
- show total consumption of appliance from mains power and solar power. Reset-able via push button.
Unit will be powered by 4 Suntech STP250S-20 Panels wired in series.
