Product Description

Off Grid Solar Kits With Lithium Batteries

What is an off grid system?

The off-grid solar system is a complete package that contains everything you need to generate your own energy. These systems are suitable for homes, vacation homes, offices and larger buildings that need energy independence and help create green energy.

BSLBATT off grid solar system kit with batteries includes everything needed to generate renewable energy. They are ideal in situations where there is no grid connection or power supply is insufficient or unreliable. They are also very suitable for supplementing your energy needs from renewable resources.

The built-in battery management system integrates with multilevel safety features including overcharge and deep discharge protection, voltage and temperature observation, over current protection, cell monitoring and balancing, and over-heat protection. This high-performance BSLBATT Lithium Battery has a large power capacity, with a fast charging and continuous discharge power, providing 98% efficiency. The advanced Lithium Ferro Phosphate (LFP) technology operates a wider temperature range to deliver the most dependable performance. LFP has been proven to be one of the safest Lithium technologies in the industry and is manufactured to the highest standards.


When paired with solar, the BSLBATT Powerwall is the perfect way to automatically save money while paying the lowest possible cost for your energy.




Our intelligent software combines weather, utility rate, and historical solar production and energy consumption data to continually drive energy efficiency and improve system performance to meet your specifically tailored goals.

There are two main types of off-grid solar systems, completely off-grid and partially off grid.

Completely off-grid

The completely off-grid solar system is not connected to the grid, which is very suitable for those who want to generate green energy or need electricity but there is no connection or the cost does not allow for grid connection.

A complete off grid solar kits includes solar panels, panel supports, 48V lithium batteries, power inverters, and everything needed to generate, store, and deliver off-grid energy.

Partially Off-grid

Part of the separated grid solar system is connected to the grid, which can not only supplement the grid power, but also provide a green alternative to the grid as a backup. These systems are also useful when grid power is intermittent, so your property always has the energy it needs.

The partial separation grid solar system includes the same equipment as the complete off-grid system, but also includes the equipment required for integration with the mains.

Every off-grid system includes everything needed to install, generate, store, and deliver renewable energy. We can also design and install your system for you!

The BSLBATT storage systems capture excess solar energy to provide power when it is needed most—when the power goes out, when electricity prices spike, or when the sun isn’t shining. BSLBATT curates a portfolio of hardware options from internationally recognized battery and power electronics suppliers in order to provide homeowners and businesses with safe, reliable, and renewable power.

As one of the top lithium ion solar battery manufacturers, we can custom different specification batteries. Voltage: 12 to 48V; capacity: 50Ah to 600ah.


“BSLBATT batteries eliminated the most difficult challenges we face when building microgrids in remote tropical locations. The batteries are much easier to transport and they have a good chance of lasting the entire 20 years. This means BSLBATT batteries generally pay for themselves in under 4 years!”
