B-LFP48-120 in Renewable Energy Applications

48V Lithium Solar Batteries

The 48V 120AH Lithium Solar Batteries Energy Storage Systems family is designed as a drop-in replacement for similar sized lead-acid batteries offering twice the run-time and nearly half the weight. The 48V Lithium Solar Batteries are designed for lower voltage, lower power, and longer run-time applications. They are built with LFP Technology that offers outstanding intrinsic safety and excellent float and cycle life resulting in a low cost of ownership.

If you’re looking for energy storage for your residential solar system for grid-tie or off-grid, these 48V Lithium Solar Batteries is a great option. Deep cycle batteries are a key component in off-grid solar electric systems, and for grid-tie or emergency backup power systems with or without solar. For renewable energy systems, the 48V Lithium Solar Batteries are compatible with Outback, Schneider Electric, Magnum, Morningstar, and many other leading brands of inverters and solar charge controllers.

Our B-LFP48-120 is a 48V 120AH Lithium Solar Batteries. This lithium iron phosphate (LiFePO4) battery is ready to replace your lead-acid battery bank in your solar energy system or electric vehicle. It’s powerful, rugged, and has an extremely long cycle life. The 48V 120AH Lithium Solar Batteries can store more energy and charge faster than lead-acid battery alternatives.
