What are the benefits of powerwall? Before answering this question, let's first understand the concept and functions of the wall mounted lithium battery source?Wall mounted DC power supply system is specially designed for small capacity DC power supply system, which is suitable for operation of small switch stations, small user substations, small substations and high voltage power wall distribution systems in high-rise buildings. It is composed of charging module module, monitoring silicon chain, small bracket and wall mounted power supply box with integrated design idea. The wall mounted power supply system integrates AC/DC modules, monitoring, silicon chain, and AC/DC power distribution. Only external battery packs are required to form a complete DC power supply system. The system has the characteristics of small volume, simple and elegant structure, convenient and simple installation, flexible assembly system, etc. Modular design, N+1 hot standby, smooth capacity expansion, to meet different capacity systems. The module can be plugged in and out with electricity, which is safe and convenient to replace. The monitoring function is perfect and highly intelligent. Large screen LCD is used for Chinese character display and audible and visual alarm.
All components of wall mounted battery DC power supply system: AC power distribution, rectifier module, DC feed realize full parameter local and remote monitoring; The main monitoring quantities include: module startup/shutdown, charging mode, output voltage regulation, output current limiting point setting, PT power supply current limiting, battery circuit breaker tripping alarm, and automatic battery charging management. The monitoring system is equipped with standard RS-485 and RS232 interfaces to facilitate access to the automation system and realize "four remotes" and unattended operation. CDT and MODBUS communication protocols are provided for users to choose. Automatic management and maintenance of the battery: real-time monitoring of the voltage, charging and discharging current of the lifepo4 battery pack, automatic control of equalizing, floating charging and regular maintenance equalizing of the battery pack. The intelligent system has the function of battery temperature compensation and realizes on-line monitoring of bus insulation. The system is equipped with automatic step-down silicon chain. The step-down unit has automatic control function and can set the output voltage of silicon chain. AC power distribution unit includes one circuit of single-phase AC input, and one circuit of PT standby power supply can be selected; The system automatically limits the system output power when PT is powered. The DC power distribution unit provides two bus combining outputs, three bus controlling outputs and one battery circuit breaker.

The wall mounted power box is suitable for the system of 38AH/220V and below or the home battery energy storage system of 65AH/110V and below. Up to 3 naturally cooled digital intelligent modules can be installed. The step-down unit has the function of automatic silicon chain step-down. It adopts CPU intelligent control. The maximum working current is 2.0A, the impulse current is 30A/0.5S, and the silicon chain output voltage can be set (the maximum working current of 110V system is 3.0A). The monitor in the lifepo4 powerwall power supply system adopts LCD display, Chinese menu and key operation, which can realize system parameter setting, system working parameter display, system fault indication and system parameter calibration. The monitor can be connected to the battery inspection unit (DCXJ-19) to complete the voltage detection of 18 batteries, and monitor the battery voltage, bus control voltage, bus control current, battery charging and discharging current and module status at the same time. RS232/RS485 communication interface is provided. CDT and MODBUS communication protocols can be selected to connect with the automation system of the power station, and one single-phase AC input and one PT100V input are provided. During PT power supply, the power wall solar system automatically limits the output power and the output current is 2.0A. 110V system, output current limiting 3.0A. The monitor has the functions of automatic battery management, bus insulation monitoring, bus grounding fault alarm and battery breaker trip alarm. There is a monitoring fault maintenance bypass switch. Before pulling out the monitor, close the bypass switch to ensure that the control bus is not powered off. Outgoing mode: lower in and lower out (outlet aperture 4* Φ 30) And the module can be hot swappable。

What are the benefits of powerwall? Compared with traditional batteries, wall mounted lithium batteries have the following characteristics
(1) Working voltage up to 3.6~4.0V;
(2) Small volume and light weight;
(3) High specific energy;
(4) No memory effect;
(5) Small self discharge, long storage time;
(6) Long cycle use;
(7) No pollution or little pollution;
(8) High security.
What are the benefits of powerwall? Compared with traditional energy, the wall mounted lithium battery system is a system that can charge, discharge and store energy, and green environment is one of its main characteristics. Secondly, the wall mounted lithium battery with solar panels can be monitored and adjusted according to customer needs, such as staggered storage and discharge according to the peak of the power grid. Even businessmen in some countries use the wall mounted lithium battery energy system to deliver electricity to the national grid and collect profits
