Household lead-acid energy storage apparatus

Abstract

The invention discloses a household lead-acid energy storage apparatus. The household lead-acid energy storage apparatus comprises a solar cell, a lead-acid energy storage unit, a bidirectional control inverter, a remote controller and a household appliance load, wherein the external ends of the solar cell and the domestic appliance load are connected with the bidirectional control inverter separately through cables; the energy source end of the lead-acid energy storage unit is connected with the energy source control end of the bidirectional control inverter; charging-discharging DC / DC and DC / AC conversion modules are arranged in the bidirectional control inverter; the DC / DC input end is connected with the output end of the solar cell; a switch is arranged at the DC / AC input end; and special energy management software is arranged in the remote controller for realizing optimization and control of a man-machine interface conveniently. According to the household lead-acid energy storage apparatus, the capacity of the lead-acid energy storage unit is determined according to the household appliance load power; and therefore, the energy storage apparatus is easy to increase or decrease the capacity, convenient to install, rapid and convenient to operate, and particularly suitable for households in regions without electricity or regions with unstable power grid and electric energy.
