How long will it run a refrigerator?

A typical fridge draws roughly 150W average, so the 3,600Wh battery can keep one running for well over a day, longer if you limit door openings and use eco settings. High-draw appliances like space heaters will drain it in a few hours.

How does it compare with the EcoFlow Delta Pro?

Both offer around 3,600Wh and 3,600W output. The Delta Pro supports expansion batteries and a higher solar input, while the PowerMax 3600SE keeps everything in one unit and adds a 10ms UPS mode.

Can I charge it with solar panels?

Yes. It accepts up to 1,600W of MPPT solar input, but panels are not included, so you need to buy compatible panels separately.

What can the 5,400W peak handle?

The peak rating covers startup surges from motors and compressors, such as a well pump or air conditioner, for short bursts. Continuous loads should stay at or below 3,600W.

Does it work as a UPS for a home office?

Yes. The 10ms switchover keeps a desktop, router or NAS running through a brief outage, though it is not a whole-house automatic transfer switch.

What comes in the box?

The power station itself, an AC charging cable and documentation. Solar panels, expansion batteries and vehicle charging cables are sold separately.

Our take on the OSCAL PowerMax 3600SE Portable Power Station

The OSCAL PowerMax 3600SE is a large home-backup and off-grid power station built around a 3,600Wh LiFePO4 battery. It delivers 3,600W of pure sine wave AC power with a 5,400W peak, enough to run a fridge, a space heater or a microwave, and it can recharge from an AC outlet at up to 1,800W, from solar at up to 1,600W MPPT, or from a 12V/24V vehicle. A 10ms UPS switchover, app control and a full spread of AC, USB-C, USB-A, DC and Anderson ports put it in the same class as the EcoFlow Delta Pro and Bluetti AC300, which offer similar capacity and output but cost more and often need separate battery modules. It suits homeowners who want outage backup, RVers and off-grid users who need serious capacity in one box.
