  • Harveypower's BMS system monitors and regulates wall mount lithium battery charge and discharge status. The monitored wall mount battery characteristics include the detection of battery type, voltage, temperature, capacity, state of charge, power consumption, remaining operating time, charge cycles, and more.
  • It can process and monitor up to 16 wall battery packs at the same time, provide a battery balancing function, manage different batteries with the same charge and discharge requirements, and ensure the optimal utilization of the remaining energy in the battery.

  • LED Display (Optional)

Build an LED display outside the product group to visualize the overall data and status of the battery pack. You can also DIY the operation functions of the display according to your needs.

  • Self-heated Function (Optional)
The BMS system can be set with a self-heating function to make the battery system suitable for lower temperatures. 
When the temperature is below 0°C, through self-heating, the temperature of the battery can rise to above 10°C within a few tens of seconds, thereby activating the normal application of the battery. 
Start heating temperature: ≤0℃. Stop heating temperature: ≥10℃.
  • Bluetooth Function (Optional)
Can communicate with BMS in wireless mode. Users can connect the battery pack via Bluetooth, which allows visualizing all-important battery information such as voltage, current, temperature, SOC, SOH, errors, etc. 
Some parameters and switch systems can also be controlled remotely, making everything easy to use and manage.
  • State of Health (Optional)
It can detect and reflect the battery capacity, health, and performance status with the accumulation of battery usage time and the impact of the environment, effectively guiding how to maintain the battery

Not only can we know whether the remaining available capacity of the battery can meet our demand for the total temporary power consumption, but also know when each single battery and battery pack needs to be replaced and repaired.

  • More Optional


How long can this wall mount solar battery power a house?

10 to 15 hours.
Usually a small and medium-sized family consumes 0.5-0.8kwh of electricity per hour, which means that a wall mount battery of 8.8kwh can support electricity consumption for 10-17 hours.

Does the wall mount lithium battery support outdoor installation?

Our wall mount batteries are IP65 rated, supporting all weather conditions for indoor or outdoor installation.
However, for extreme weather in different regions, we recommend installing the battery in a cool, dry room without a strong magnetic field to better preserve battery performance.

How to install a wall battery pack to the wall?

Step 1: fix the back bracket on the wall with 6 screws(A total of 12 screw holes are optional).
Step 2: snap the back groove of the wall mount battery into the corresponding groove of the bracket.

How many wall mount lithium battery would it take to power a house?

You will need three or more backup batteries for the whole house in most cases.
They will be enough for essential loads and such large appliances as a central A/C, electric range, off-grid vehicle charging, electric dryer, electric water heater, pool equipment, etc.
