Neexgent South Africa 5kw Lithium Battery Energy Storage Battery Powerwall 48v 100ah For Solar Power


• High cycle life
≥6000 cycles @80% DoD for effectively lower total of ownership cost

• Longer service life
Low maintenance batteries with stable chemistry.

• Built in circuit protection
Battery Management System (BMS) is incorporated against abuse.

• Battery storage
up to 6 months thanks to its extremely low self 
discharge (LSD) rate and no risk of sulphation.

• Quickly recharge
Save time and increase productivity with less down 
time thanks to superior charge/discharge efficiency.

• Extreme heat tolerance
Suitable for use in a wider range of applications where 
ambient temperature is unusually high: up to +60°C.

• Lightweight
Lithium batteries provide more Wh/Kg while also 
being up to 1/3 the weight of its SLA equivalent.

NX-48100 Wall-mounted Lithium Battery
**Power your home and electric vehicle with renewable energy you control and reduce your 
   reliance on the grid. 


**With solar, you typically generate more clean energy than you need. By combining with 
   NX-48100, a rechargeable home battery, you can store excess energy from your solar 
   panels for use anytime—even during a power outage. 


**NX-48100 can detect a power cut, disconnect from the grid and automatically restore power 
   to your home within a fraction of a second.

**With NX-48100 continuous power output, your home or business keeps running with little disruption.


  • Powerwall Solar Energy System for Home Use

Powerwall is the device with rechargeable lithium-ion battery for Home Solar Energy System. With its BMS Control, homeowners can generate and store their own energy, reducing their reliance on the power grid and increasing their energy independence.

  • Powerwall: Your Home Assistant for Solar Energy System 

Powerwall can store excess solar energy generated during the day for use at night or during times of low solar production. 6000-cycle life increases the self-consumption of solar energy and reduces the amount of energy exported to the grid.

  • Design Your Own Powerwall: Lifepo4 Solar Battery with TUV

48v 100ah&200ah Powerwall for your suitable alternatives. It is supported to parallel Max. 15 devices in serices and design unique box.

1. Does the powerwall support customized service?
A: Yes, it does. The powerwall is our unique product with patent design. It is supported to design the logo and color if you have need.


2. Are the batteries Grade A and brand new?
A: Yes, they are. We have CATL, BYD, CALB, EVE...All of our battery are Grade A and brand new battery. Please feel free to contact us and we will show QR code, specification and real photos for you. 


3. What is the life expectancy of a Lithium battery?
A: The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years, or 2000 to 8000 charge cycles. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.


4. Is the cells I bought balanced?
A: we know the importance of maintaining the consistency of each cell in the battery pack, so we will match and balance all cells to ensure that the internal resistance, voltage and capacity of cells are completely matched and balanced before delivery.  This process is very necessary


5. Except battery, do you also provide other assessories, for example Busbar, BMS?
A: Sure, we can supply the whole installation accessories of assembling battery, just feel free to contact us, we will match for you according to your need.
