Apex 300+B500K+500W 3,840W, 7,884.80Wh, 500W Solar Generator Kit Apex 300+B500K+500W 3,840W, 5,120Wh, 500W Solar Generator Kit
Editor's Take
The Apex 300+B500K kit packs a hefty 7,884.8 Wh of storage and a 3,840 W continuous output, which makes it feel more like a small home backup than a portable unit. At $5,597 it sits in a premium price bracket, but the combined capacity and 500 W solar input give it genuine off‑grid credibility without resorting to marketing hyperbole.
Who is this for?
It's aimed at homeowners or serious RV travelers who need a reliable, high‑capacity backup that can also be recharged via a modest solar array.
