Big Battery APEX 10K Off-Grid Inverter

If your home demands serious power without compromise, the BigBattery APEX-10K delivers 10,000W of clean, pure sine wave output built to handle it all from everyday loads to heavy-duty 240V appliances.

• All-in-One Hybrid Power – Combines inverter, solar charger, and battery charger so your solar, battery, and generator all work together without needing separate components.
• Dual MPPT Solar Input – Two independent MPPTs handle up to 11 kW of PV input with a wide 125–450V range, giving you real flexibility when designing your array.
• Split-Phase 120/240V Output – Runs everything from standard household circuits to heavy-duty 240V appliances, with a 6 HP motor load capacity built for demanding setups.
• Scalable Parallel Capacity – Stack up to six units in parallel, with three or more units capable of forming a three-phase output for larger installations.
• Smart Energy Management – Built-in time-of-use scheduling and intelligent charge/discharge modes help stretch your battery life and reduce energy costs over time.

Whether you're running on solar, grid, or generator, the APEX-10K switches between sources automatically so your critical loads never miss a beat. The 63A bypass passthrough keeps your heaviest appliances running without putting extra strain on the inverter itself.

Battery flexibility is a real strength here it works with lithium-ion, lead-acid, or user-defined battery banks at 48V, with a max hybrid charge current of 200A. RS485, CAN, and USB communication tie directly into your BMS for live protection and performance data you can actually rely on.

Installation is refreshingly clean bottom-entry wiring keeps the job organized, and integrated circuit breakers for utility, load, battery, and PV mean fewer external components to source. Intelligent fan cooling and a solid operating range of 14–131°F make this a system built to perform day in and day out.
