With more than 5 years of experience in battery storage manufacturers, We offer cost-effective home battery backup. Welcome lithium storage battery OEM Order. Wall-mounted Energy Storage System is an integrated lifepo4 battery system that stores your solar energy for ups battery backup protection, so when the grid goes down your power stays on.


This 10KWh 51.2V 200Ah lifepo4 battery solar energy storage system has the advantages of large capacity, high power, small self-discharge, and good temperature resistance. Because of its reasonable structure, it is easy to assemble and disassemble.

The energy storage system adopts the latest Home Energy Storage System battery system (backup home battery). With rich experience and advanced techniques, it features a fashionable design, high energy, high power density, long service life, and easy installation and expansion, all of which reflect the real requirements of the end users and the strongest technical capability.

It is a kind of environmentally friendly backup power system. We use phosphates rather than cobalt to avoid environmental concerns by lowering the possibility of a thermal runaway because of improper disposal and saving production costs as well. Compared with other products in the market now, this kind of product experiences a lower rate of capacity loss.

With state-of-the-art power conversion and energy storage technologies, our Energy Storage System (ESS) offers high-efficiency power conditioning capabilities for demand management, power dispatch, renewable energy smoothing, etc. Our ESS can provide comprehensive energy storage for residential, commercial, and utility applications. Our lifepo4 battery portfolio covers cells, 48V modules, cabinets (indoor/outdoor), and containers, which offer customers excellent scalability and adaptability to a wide variety of requirements.

Trouble Shooting Steps

Preliminary determination steps:1) Battery cannot be turned on, switch on the lights are all no lighting or flashing.
If the battery’s external switch is ON, the RUN light is flashing, and the external power supply voltage is51.2vor more,
the battery is still unable to turn on, please contact the distributor.
– The battery can be turned on, but the red light is lighting, and cannot be charged or discharged, red light is lighting,
that means the system is abnormal, please check the values as follows.

– Temperature: Above 50°C or under -10°C, the battery could not work. Solution: move the battery to the normal
operating temperature range between-10°C and 50°C.4) Current: If the current is larger than 100A, battery protection
will turn on. Solution: Check whether the current is too large or not, if it is, change the settings on the power supply side.

– High Voltage: If the charging voltage is above 58.4Vbattery protection will turn on. Solution: Check whether the voltage
is too high or not, if it is, change the settings on the power supply side 6) Low Voltage: When the battery
discharges to 40V or less, battery protection will turn on. Solution: Charge the home battery backup for some time, and the red
light will turn off. Excluding the four points above, if the faulty is still can’t be located, turn off the battery and repair it.

– The battery cannot be charged or discharged1) Cannot be charged disconnect the power cables to measure
the voltage on the power side if the voltage is 56 5-57.6V battery. connect the power cable and try again, if
still does not work turn off the battery and contact the distributor.2) Unable to discharge: Disconnect the power cables and
measure the voltage on the battery side. if it is under 40v. please charge the battery: if the voltage is above 51.2V and still
can’t discharge, turn off the ups battery backup and contact.

Matters Need Attention

– Do not immerse the lifepo4 battery in water or allow it to get wet.

– Do not use or store the ups lithium battery near sources of heat such as a fire or heater.

– Do not reverse the positive(+) and negative(-) terminals.

– Do not connect the battery directly to wall outlets or car cigarette-lighter sockets.

– Do not put the ups lithium battery into a fire or apply direct heat to it.

– Do not short-circuit the ups battery backup by connecting wires or other metal objects to the positive(+) and
negative(-) terminals.

– Do not pierce the battery casing with a nail or other sharp object, break it open with a hammer, or step on it.

– Do not strike, throw or subject the battery to severe physical shock.

– Do not directly solder the ups battery backup terminals.

– Do not attempt to disassemble or modify the lifepo4 cells in any way.

– Do not place the battery in a microwave oven or pressurized container.

– Do not use the battery in combination with primary batteries(such as dry-cell batteries) or lifepo4 cells of
different capacity, type, or brand

– Do not use the battery if it gives off an odor, generates heat, becomes discolored or deformed, or appears
abnormal in any way. If the battery is in use or being recharged, remove it from the device or charger
immediately and discontinue use.

– If the battery leaks and electrolyte gets in your eyes, do not rub them. Instead, rinse them with clean running
water and immediately seek medical attention. If left as is, electrolytes can cause eye injury.
