China Lifepo4 Powerwall Battery Manufacturer

The Powerwall uses rechargeable lithium-ion batteries. These batteries have an exceptionally long life and safely store and discharge large amounts of electricity.

Powerwall is a stationary rechargeable lithium-ion home battery energy system introduced by Tesla in 2015. When the grid loses power, the Powerwall battery can use the stored solar energy to continuously power appliances, which is very versatile. It can be customized according to energy needs and reduce dependence on the grid, making it an excellent home energy storage solution.

The KHLiTech power wall battery comprises 16 prismatic 100Ah lithium cells with a built-in intelligent BMS.
The BMS has a communication function and can communicate with the inverter. Communication ports include RS485, RS232, and CAN.
Powerwall batteries support parallel connections to increase capacity, ranging from 10kwh, 20kwh, 30kwh, 60kwh, and more.
The Lithium power wall battery has an LCD that can obtain the battery’s voltage, current, capacity, and SOC status in real time.
Of course, you can also connect to Bluetooth to receive information and control the system through your mobile phone.

When the sun rises, the solar panels absorb sunlight and convert it into usable energy to power the home. When the appliance uses energy, the excess is stored in the powerwall. Once the Powerwall is fully charged, the system sends the extra power back to the grid.
When the sun goes down and the solar cells cannot produce energy, the powerwall starts working to provide electricity to your home. This creates a cycle of clean, renewable energy.
Suppose your system does not have solar energy. In that case, the powerwall can charge when your public electricity tariff is low and discharge it during the peak period of electricity consumption or when the electricity tariff is high, helping you achieve the purpose of saving electricity bills. During a power outage, the Powerwall detects the failure and automatically switches to the home’s primary energy source.

If you want to go off the grid, then powerwall batteries are the way to go. KHLiTech’s new version of Powerwall supports up to 32 units in parallel and has ample energy storage to meet your home’s all-day power needs and achieve energy independence. The same applies to covering losses caused by brief power outages in business.

In addition to the cost of the battery itself, Powerwall batteries also require gateways, related hardware, and labor costs. 30% federal tax credit and eligible for local rebates if solar rebates and incentives are available locally.

Powerwalls with different parameters have different sizes. The Tesla Powerwall 2, for example, measures approximately 45 inches high, 30 inches wide, and 6 inches deep. The dimensions of KH-ES5KPW are L445mm×W259mm×H600mm. Click the link to view the KH-ES5KPW powerwall datasheet.

Keheng Chem and Tesla’s powerwall backup power supply is the best choice during a power outage. They both use lithium battery storage technology and also provide different product specifications. As shown in the picture:

Capacity:

The capacity of tesla powerwall2 is more significant than that of Keheng. You can consider a large battery if you have a large device or need to consume a lot of power. Otherwise, choose a small battery. Of course, the battery capacity can also be increased by stacking powerwalls.

Round trip efficiency:

Keheng’s round-trip efficiency is 96%, Tesla powerwall 2’s round-trip efficiency is 90%, and Keheng has higher efficiency. That is, Keheng loses less energy.

Round-trip efficiency means that the energy generated by the panels is sent to the solar cells, which are stored in the form of DC. To use the power in the battery, it needs to be converted to AC, and a small amount of energy is lost in this process, i.e., power wall 2 loses about 10% of its power.

AC/DC Coupled:

The Tesla Powerwall 2 is AC coupled, while the Keheng is DC coupled. AC coupling is easier to install and allows the system to be designed around user needs. Although DC coupling is troublesome to install and more expensive, DC-coupled batteries are also more efficient.

Warranty:

Both have a 10-year warranty, but Tesla offers 70% degradation and Keheng’s 60% degradation. Over time, batteries degrade in performance, become less efficient, and use energy faster. If you’re looking for a battery that lasts a long time, between two, consider the Tesla powerwall.
