Product Description
If your Ionic GenBox 1200S gives you about 6 hours of refrigerator backup on a full charge, the GenBox 1.3B Expansion Module doubles that — and then some. Each module adds 1,380Wh of the same LiFePO4 battery capacity found in the base unit, stacking directly onto your existing system to extend your protection through longer outages without needing a second base unit or a generator.
Installation takes about 5 minutes. Stack the module onto the base unit, secure the included bracket, and connect the battery cable. The GenBox 1200S detects the new module automatically — no programming, no app interaction, no electrician. The entire system charges and discharges together as a single unit, with total capacity shown on the base unit's display.
More Runtime, One Step at a Time
You don't have to buy everything at once. Start with the GenBox 1200S and add expansion modules as your needs or budget allow. Each module adds approximately 6 hours of full-size refrigerator runtime:
- Base unit alone: ~6 hours
- Base + 1 module: ~12 hours
- Base + 2 modules: ~18 hours
- Base + 3 modules: ~24 hours
Up to three modules can be added per GenBox 1200S, bringing total system capacity to 5.52kWh. Combined with the 1200S's Eco Smart Cycle feature, that 24
Frequently Asked Questions
Will the GenBox 1.3B work with any other GenBox model?
A: No. The GenBox 1.3B Expansion Module is designed exclusively for the Ionic GenBox 1200S. It is not compatible with the GenBox 100, 400, 800, 1200 (portable), or 2400. If you own a portable GenBox model and need more capacity, additional standalone units are the recommended solution.
Can I add modules one at a time as my budget allows?
A: Yes, and that's exactly how most customers build their system. The GenBox 1200S base unit works perfectly on its own from day one. You can add one module now and another later — each one is recognized automatically when connected, with no reconfiguration needed. Up to three modules can be added per base unit.
How does the system handle charging across multiple modules?
A: All connected modules charge and discharge together as a single unified system, managed entirely by the GenBox 1200S base unit. You don't need to manage each module individually. Total capacity is displayed on the base unit's screen, and the Ionic GenBox app reflects the full system when connected via Bluetooth.
Do I need any tools or special skills to install this?
A: No special skills or tools are needed. The installation process is stack, bracket, connect — typically completed in about 5 minutes. Full instructions are included, and Ionic's U.S.-based support team is available if you have any questions during setup.
