How to choose battery for home solar energy storage system
Aug 27, 2022
With the gradual tightening of global energy supply and increasingly serious environmental pollution, independent and environment-friendly energy supply is becoming more and more important, and more and more households around the world choose to embrace this green energy transition with green electricity at home.
However, in the face of the numerous and chaotic household energy storage products on the market, how to choose has become a troubling problem. Careless choices can lead to inability to solve the actual needs and increase the cost, and even the occurrence of potential safety hazards that endanger public safety.
Both the market and consumers need an economical and safe solution for residential energy storage systems. We've put together 4 useful home energy storage system buying tips for you here.
1, Choose safe and stable battery materials
The current gold standard in battery storage system technology is lithium iron phosphate (LiFePO₄). Lithium iron phosphate batteries do not overheat and can be charged and discharged at high power. Long service life is guaranteed even in changing weather conditions. What's more, lithium iron phosphate batteries are one of the few lithium-ion batteries that do not contain cobalt, and they do not contain toxic heavy metals such as lead and nickel commonly found in other batteries.
2,Choose a flexible battery capacity
The energy storage capacity of the energy storage system, measured in kilowatt-hours, should normally be 0.9 to 1.6 times the output of the PV system or the actual system. How much capacity is required depends on the user's consumption behavior.
3,Choose an intelligent battery management system
In the battery energy storage system, the most effective way to reduce the risk of fire is to add a sensing system for battery temperature, current and voltage to the circuit of the battery pack, and to manage the battery in an abnormal state. The battery management system we call BMS. BMS can effectively realize the thermal management of the battery, avoid the problem of thermal runaway of the battery from the source, and improve the safety and reliability of the battery energy storage system.
4,Choose system products with cloud data monitoring
An intelligent and complete household energy storage system is often matched with a complete data support system, such as human-computer interaction pages and monitoring cloud systems or smart APPs, so as to check the operating status of the system at any time, including the working status of the input side, the working status of the battery, and Load 24 hours working status, etc. At the same time, these intelligent supporting products can be used to set, control, and adjust the power output and working mode of the system.
