Plus, the RHINO 2 features an interactive LED display on the side of the unit, along with full CANBus and RS485 communication protocols, so you can always monitor the status and performance of your power. The RHINO 2 even boasts an internal fire extinguishing unit for ultimate peace of mind when installed inside or outside your home. Supported by these robust safety and visibility features, this power system is engineered to withstand up to 8,000 cycles at 80% depth of discharge (DoD), achieving lifespans of up to 10+ years!

We pair our RHINO 2 with two cutting-edge 6000W Lux inverters, which each feature their own LCD touch screen display, 2 MPPT inputs, an integrated UPS module for seamless on and off-grid switching, and the ability to handle PV arrays of up to 8000W. Plus, through its smart load control, AC coupling abilities, and peak shaving function, you can meet your power needs and protect your home against unstable grids or rolling blackouts, while seeing huge savings each month on your electric bill. But if you already have an inverter at home, don’t worry! The RHINO 2 is compatible with dozens of 48V inverters on the market today.
