There's a cheaper option with fewer features available from a Spanish company (all info in Spanish): http://revosolar.com/solar-shop/es/accesorios-/188-inhibidor-inyectar-en-la-red.html
A diagram here (also spanish): http://revosolar.com/solar-shop/es/index.php?controller=attachment&id_attachment=138

The areas of the US that are good for grid tie solar have net metering that pays you in credited kWhs for anything that you feed back to the grid. In some areas/ states that is not the case and a product like this would be useful.
