i like to build a 4KW pure sine wave inverter, as a prototype for more of this to come.
i like someone to build the main electronics, with no box and maybe with no transformer, so i can find the transformer in the local market, to reduce the shipping cost.
if this prototype will be in a good quality, the freelancer who got the job, will get a lot of orders for this inverters and other 1,2,3,5,10 KW orders.
please give a decent offers because I am funding the prototype from my own money.
i am working on a solar energy project and do it to help our world to be a better place to live in, so if you have the same vision, we can do a great things together.
this inverter will be connected to deep cycle gel batteries or acid batteries, and will give power for home or outdoor events.
continuous output power 4000W (real pure sine wave)
output 220v AC
DC in 21-30 v
no load current drew 1-2 A
battery low shutdown [url removed, login to view]
battery low alarm 11v
cooling fan connector
