Excellent discharge characteristics

CMX 48200 LFP battery is a Tesla Powerwall Alternative 10kwh 48V 200Ah Lifepo4 Lithium Ion Battery. Different from any other China suppliers. Coremax 10kwh 48v 200Ah come with 16pcs cells in serice. That’s means , our battery pack nominal voltage is 51.2 VDC. This will make the battery pack have more energy and more powerfull to solar inverters.

Long cycle life

Prismatic lifepo4 battery cells Provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.


  • 1. CMX power mount 10kwh lithium battery Compatible with different type energy source, and making full use of clean energy. The output power of solar energy and wind energy can be effectively smoothed. The impact to the power grid and users, which is consulted by intermittency of new energy can be effectively overcome.
  • 2.Providing uninterrupted power to users. Can satisfy the requirement of users under the extreme environment, such like the power failure caused by earthquake and flood.
  • 3. 10kwh lifepo4 battery Saving electricity for users by peak-shift. Under the price of peak valley, if the power consumption is big in the rash hour, this system can help to save expenditure by storing electricity during the electricity troughs, and using in the peak time.

Datasheet PDF

These solar batteries are rated to deliver 10 kilo-watt hours kWh per cycle. Check your power bills to find the actual kWh consumption for your home or business. Find the average per day and the peak daily kWh consumption. We have solar battery packs available that provide power storage from 1kWh to more than 100 kWh. Learn the price of 10kWh backup battery power storage for the lowest cost 10kWh batteries.

What is a Kilo-Watt Hour?

A kilo-watt hour is a measure of 1,000 watts during one hour. The abbreviation for kilo-watt hour is kWh. So 1,000 watts during one hour is 1 kWh. The power company measures energy in kWh in order to calculate your monthly bill.

How Many Kilo-Watt Hours Do You Need?

The average home uses 900 kWh per month, or 10,800 per year, according to the U.S. Energy Information Agency EIA. That means the average power required per day is 30 kWh. Now, when sizing a grid-tied solar battery system for daily usage, you will want a system that can deliver up to 30 kWh, or possibly more for peak usage days. However, if you also want the system to provide off-grid backup battery storage, then you will typically choose 3X to 5X the daily average, or 90 to 150 kWh. This should provide ample storage for complete system autonomy in case of an extended power outage of 3 to 5 days. Combine the battery storage with a PV solar panel system to ensure that you will have a renewable power source to keep the batteries charged.
