20kWh 48V 400Ah Lithium Ion Solar Battery
20kWh battery is a lithium iron phosphate battery with four 5kWh batteries in parallel. It has a built-in BMS system to ensure balanced charging and discharging of each battery pack. And it is protecting against overcharging and overdischarging. And it monitors temperature changes in real-time to prevent the risk of fire from high battery temperatures. Equipped with an LCD screen, it displays battery capacity and voltage. The lithium battery features a maintenance-free design, suitable for use in normal temperature environments, requiring minimal maintenance. It works with solar energy system or independently. Then it will provide uninterrupted power supply for your home.
Lithium batteries can be used with solar inverters, allowing setting of charging and discharging times. This enables charging during off-peak hours and supplying power to household appliances during peak hours or selling excess power to the grid for profit. The built-in intelligent safety system of lithium batteries provides multi-level safety protection, including a built-in DC circuit breaker to cut off power when necessary.
20kWh battery can operate over a wider temperature range and are proven to be one of the safest lithium batteries available. It is the ultimate choice for residential energy storage batteries.
Features of the 20kWh battery
The best alternative to Tesla Powerwall: we all know that Powerwall 2 uses 2170NCM battery cells, which have high energy density but are very expensive. And Tesla is also considering cooperating with CATL to use LiFePO4 cells as the future home energy storage battery. This lithium iron phosphate cell is cheaper and also has high energy density and conversion efficiency. In the future, the 20kWh LiFePO4 battery will be one of the best options for home energy storage.
Independence: A 20kWh battery allows you to have a completely independent power supply system, even in the event of a power outage, to maintain the home power supply. When combined with a solar power system, you’ll reap the benefits of a green power supply that never goes out.
Modular design: The 20kWh energy storage system consists of four 5kWh battery modules connected in parallel. It can also be used as a storage system for larger capacities such as 30kWh, 40kWh, 70kWh, etc. It is also available with optional wheels. And there are optional wheels designed to make moving the battery pack easy.
DC coupling: DC coupling is cheaper and more efficient than AC coupling for batteries. The DC output can also be more flexibly connected to other devices. Of course, if you need AC coupling, we can also add inverters, converters or PCS modules to your energy storage system.
Easy installation: No complicated wiring is required, you just need to follow the steps in the instruction manual to connect all the positive terminals of all the battery modules to one circuit and the negative terminals to another circuit. The RS485 communication interfaces of all batteries can be connected in order with RJ45 wires. Simple operation.
