Who is this for?
Homeowners who need reliable backup power for essential appliances and are willing to invest in a modular, expandable system.

Frequently Asked Questions
Can the Apex 300+B500K run a typical refrigerator and a 55‑inch 4K TV for an entire night (8 hours)?
With 13 kWh of stored energy it can comfortably cover the combined draw of those devices for about eight hours, assuming average consumption rates.
Is this system suitable for powering an entire house during a prolonged outage?
While the 3,840 W output handles many critical loads, it may fall short for whole‑house demand, especially high‑draw appliances like electric heating or large HVAC units.
Is $3,299 a reasonable price for the Apex 300+B500K’s capabilities?
At roughly $250 per kilowatt‑hour of usable storage, the price is competitive for a high‑output, expandable solution, but it is still a sizable investment for most households.
What should owners consider when installing the Apex 300+B500K?
The unit’s 3,840 W inverter and modular battery packs require adequate space and often professional installation, and users should plan for the system’s weight and ventilation needs.
