Six AC outlets and a bolt-on DC hub turn the Apex 300 into the closest thing to a built-in van electrical system you can buy as a box. The 2764.8 watt-hour LFP battery feeds 3840 watts of AC and, uniquely in this guide, 120 and 240 volt output at the same time. The Hub D1 adds a 50 amp Anderson connector, two cigarette lighter ports, two DC5521 ports and USB-C and USB-A ports, so a 12V compressor fridge, lights and a Starlink-style dish can run without the inverter.
That breadth means a van with a fridge, a laptop desk, an induction cooktop and a fan can run off one device. Compared with the 3840Wh Elite 400 it has less energy but a much stronger inverter and the hub, and against the 288Wh stations it is nearly ten times the storage at several times the weight. It is a fixed installation, not a grab-and-go bag.
Secure it with straps and a mounting plate, because a heavy battery in an accident is dangerous. Plan ventilation around the case, use the DC hub for fridge and lights to save inverter overhead, and recharge from solar or a DC-to-DC source on drive days. Run the DC hub's output through fuses sized for each device, since a short on a 50 amp connector is a real fire risk.
What works
- 2764.8Wh LFP with 3840W AC output
- Six AC outlets with 120V and 240V output
- Hub D1 adds a 50A Anderson and DC ports
- Runs a full van kitchen without a built-in bank
Watch out for
- Very heavy and takes payload and cabinet space
- Highest outlay among the single boxes
- Overkill for a weekend rig
