The MUST 12 kW Single-Phase Hybrid Inverter is a low-voltage (48 V) storage inverter for serious home and small-business backup. It blends solar, batteries and grid/generator power, supports export-limit/zero-export (with meter/CTs), offers TOU/peak-shaving, AC-coupling for retrofits, and has an IP65 outdoor-ready enclosure. Supply only—ideal if you already have an installer to handle wiring, protection and commissioning. (mustups.com)
