The Conext SW 120/240V hybrid inverter is perfect for off-grid, backup power, and self-consumption applications for homes and small businesses, it’s a pure sine wave, hybrid inverter system with switchable 50/60 Hz frequencies, providing power for every need. SW features 120/240 VAC output, and capable of producing 120/240 VAC output from a 120 VAC input, without the need for an external transformer. For expanded off-grid capacity, the SW is integrated with fuel-based generators as required to support loads larger than the generator’s output. It’s also self-consumption ready, able to prioritize solar consumption over the grid while maintaining zero grid export. SW hybrid inverter works with the grid to avoid peak utility charges and support the grid when utility supply is limited.
