The FLEXware 250 offers a low-cost solution for single inverter installations where space and budget are primary concern. Use one FLEXware 250 on each end of the inverter, one for DC and one for AC. THere is space for a single charge controller and single pole GFDI. Use panel mount breakers (see Electrical DIstribution) for both DC and AC circuits, and one 175 A or 250 A breaker for the main inverter breaker.

¹The FW-X240 Autotransformer cannot be used for stacking with a grid-interactive FX system. However, the FW-X240 can be used to step-up the AC output of a single grid-interactive FX system from 120VAC to 240VAC. |
