Review: Excellent expansion of solar power. - Recently bought this Bluetti B300K to exoand my AC200Max. It over doubles the power of the AC200Max. It comes with the cable to connect it. Easy to hook up. The quality of build and materials is great! It charges only through beung plugged into your Bluetti solar generator that you plan to expand the battery power of. Once hooked up, you can charge them with solar panels, plug into an outlet. The B300K comes with only one USB-A type USB input. The power button must be held down for about 3 seconds to turn on. The lights are bright. It has 4 lights to represent the batter power of it. Each representing 20% of the power. And the power button lights up. This battery has a lifecycle of up to 3,500 charges from 0 to 100. After that, the battery will deplete 20%. Meaning you CAN STILL USE IT afte the 3,500 charges. And charge it from 0 to 80% of the battery's power for a long time. The functionality is easy and nice! The B300K weighs around 65lbs. But is easy to move around. The handles are sturdy. You can also see the battery percentage with the Bluetti app. And control several different Bluetti generator models with it.

Bluetti batteries are amazing great life I use them in my trailer during the summer and for emergency power for my house in the winter I love these setups they are amazing and super easy to use.

### ⭐⭐⭐⭐⭐ Stop thinking about it and buy!
*by D***N on June 22, 2025*

I recently completed a solar setup with 6 ZOUPW 450W panels, the Bluetti AC500, and 3 B300K batteries, and I honestly couldn't be happier. The system has been performing phenomenally — I’m generating over 2.5kW of clean, reliable solar power, which keeps my essential loads running and charges the battery bank with no problem, even on partially cloudy days. The AC500 is the brains and brawn of the operation — it manages solar input effortlessly and distributes power to the batteries and devices with incredible efficiency. With over 9kWh of battery storage thanks to the 3 B300Ks, I’m confident we can run for extended periods completely off-grid if needed. The app interface, monitoring, and expandability make it feel like something straight out of a sci-fi movie. I haven’t even installed the Bluetti sub panel yet, which will allow me to supplement power directly to the house. Once that’s in place, I’ll be able to run high-demand appliances without even noticing we’re on solar. This system has turned my home into a quiet, self-reliant energy hub — no noisy gas generators, no fuel to store, and virtually no maintenance. If you're considering building a home backup or hybrid solar system, this combo is absolutely worth it. It’s powerful, scalable, and ready for any power outage or energy-conscious lifestyle. 10/10 would recommend!
