Introducing The APEX Inverter Series
Meet the BigBattery APEX Off-Grid Hybrid Inverter Series (6.5K)—engineered for true energy independence with two power-class options to match your build. Both models deliver split-phase 120/240V at 50/60 Hz with clean, pure sine-wave output, pairing seamlessly with modern LiFePO₄ battery banks for stable, efficient performance. Designed for real-world autonomy, APEX supports solar and generator inputs so you can stay powered day and night, season after season.
Built to handle demanding loads, the APEX Series features an 80A pass-through to keep large appliances and critical circuits running smoothly, while wide operating temperatures and an outdoor-ready enclosure provide dependable performance in harsh conditions. With installer-friendly bottom-entry wiring and intelligent protections baked in, APEX is a rugged, efficient, and practical backbone for cabins, homesteads, remote residences, and off-grid properties—delivering a streamlined path to reliable, all-day power.
