powerwall alternatives in the field of home energy storage.
The keheng 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. Keheng 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.
“5 kwh keheng battery 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 kh-es5kpw batteries generally pay for themselves in under 4 years!”
With or without solar, always have backup power
Keheng lithium battery KH-ES2.5-WM2 powerwall with a built-in battery management system and an lcd screen that integrates and displays multilevel safety features for excellent performance. The keheng lithium battery is maintenance-free and easy to integrate with solar or for independent operation to deliver power to your home day or night. Designed for backup power, off-grid, time of use, and self-use applications, the kh-es5kpw is consistently reliable and will keep your solar system operating during a power outage, or will use the energy stored from the daytime to power your home at night.
The world’s smartest battery management system
The built-in bms is independently developed by keheng 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 keheng 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.

A:ce/tuv/msds/iso/cb/ul/rohs certificates.etc.
Q 6. are you a factory or trading company?
A:yes,we are factory, supplying oem/odm service.
Q 7. 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. 5kwh is basic for a small home. 5 kwh battery bank is scalable for 10kwh, 15kwh, 20kwh or even more.
Q 8. how many kwh do you need for your house?
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.
