What do you know about home energy storage batteries?

household energy storage battery

when it comes to battery, you may immediately think of to provide daily necessities, such as TV remote control power of disposable batteries. What you may not realize, however, is that by using a large-capacity battery, you can provide a continuous power supply for your entire home.

Whether you experience frequent power outages, want to reduce your electricity bill, or want to achieve energy independence and arbitrage peak hours, batteries are the solution of choice for your home power supply. You don't have to deploy a complex home solar panel system in order to enjoy the benefits of the battery, but if you combine the battery with a solar panel system, you'll be able to get more benefits, especially when your utility company doesn't provide additional costs, such as when the solar panels generate excess power.

We will guide you on how to assess whether a spare battery meets your needs and how to purchase the battery system that suits your needs in the most economical way.

Solar home energy storage system is a technology that converts solar energy into electricity and stores it, usually composed of photovoltaic panels, energy storage batteries, inverters, control systems, etc.


1. Photovoltaic panels

photovoltaic panels is a device to convert solar energy directly into electricity, is composed of a series of photovoltaic cells. Photovoltaic panels are widely used in domestic, commercial and industrial power applications, as well as in public utilities and renewable energy projects.

The power generation efficiency of photovoltaic panels is affected by a number of factors, including light intensity, temperature, Angle and pollution level. Usually, photovoltaic panels can work at any Angle, but the best Angle is perpendicular to the direction of the sunlight. In heavily polluted cities or industrial areas, the efficiency of photovoltaic panels may be reduced because pollutants will cover the surface of the photovoltaic cell, affecting its ability to absorb solar energy.

2. Energy storage battery

Energy storage battery is a kind of battery that can store electrical energy and release it when needed, usually composed of lithium-ion batteries, lead-acid batteries, nickel-metal hydride batteries, etc., they have the advantages of high energy density, long life and environmental protection.

3. inverter

inverter is a kind of converts dc power to ac power of the power electronic device, usually by semiconductor switching devices, such as transistors, field effect tube, Direct current is converted to alternating current by a control switch. According to the connection between the inverter and the grid, the home energy storage system can be divided into the following types:

- grid-connected system: the photovoltaic and energy storage system is connected to the grid, and when the photovoltaic or battery power is insufficient, power can be purchased from the grid. This system is suitable for areas with stable power and relatively low electricity prices.

- Off-grid systems: suitable for areas without power grids or areas with unstable power grids that require spontaneous use of power. Off-grid energy storage converters usually come with a diesel generator interface to replenish power at night when the battery is low.

- Off-grid appliance: provides the off-grid switching function or integrates the grid-connected and off-grid. It can switch to off-grid mode in case of power failure. This system is suitable for areas with unstable power systems and frequent power outages.

4. control system

control system used to manage the whole operation of the energy storage system, to ensure the stability of family solar energy storage system, and security.
