The DELTA 3800 Gen4 is a 3,763Wh portable power station with a 3,600W AC inverter and 7,200W surge, built on automotive-grade LFP cells rated for thousands of cycles. It expands to 12kWh with extra batteries and takes up to 2,000W of solar, so it can run a home's essentials or a jobsite for extended stretches. Its sub-10ms UPS transfer makes it a backup for sensitive gear, and X-Boost pushes it to 4,600W for resistive loads. It is heavy at 67.5 lbs and larger than the mid-size DELTA units, so it is a stay-put or wheeled-cart machine rather than a grab-and-go box.

Owners of the DELTA 3800 line praise the big LFP capacity, strong surge handling and fast solar charging, and many use it as a home backup unit. The main complaints are weight and size, plus the cost of expanding to the full 12kWh.
