Re: Inverter recommendations, 48V sine wave, no grid tie

The cheapest way to convert 48Vdc to kW of sine AC is to get used UPS !!! I got a APC 5000VA ( 4300Watts) for 200$ no battery inside. It work really well for the cost!!! similar to this one.. but it output 208Vthat i converted to splitphase 120-120AC https://www.kijiji.ca/v-electricite/laval-rive-no...
