This is a combination of two EGbatt 48200W units for a residential energy storage system. Total voltage: 51.2V, total capacity: 400Ah. Rated energy: 20 kWh. This compact 20 kWh system is suitable for normal home use. It can work with many different inverter brands. Please check with our sales team to confirm whether your inverter is compatible with this battery. The battery is built with CATL LiFePO4 lithium prismatic cells and an ESS BMS, offering super long life cycles and a 10+ year warranty.
The EGbatt 48200W is an intelligent 20 kWh (20.48 kWh usable) solar battery backup system for home appliances. When combined with your solar system, you can reduce electricity consumption from the public grid by up to 90%, enabling a “local production, local consumption” model. You achieve optimum solar power storage utilization at all times. Since the home solar battery backup system operates in parallel with the grid, you only draw the amount of electricity from the grid that may be needed in addition to the stored power. This saves you money — especially given current electricity prices — and makes a valuable contribution to reducing environmental pollution.

Why Choose a Wall‑Mounted Home Battery?
Embrace clean energy – This battery system makes full use of renewable energy. The output from solar and wind power can be effectively smoothed, overcoming the grid and user impact caused by the intermittency of new energy.
Uninterrupted backup power – With this LiFePO4 battery for solar storage, you are protected during extreme conditions such as power failures caused by earthquakes or floods.
Peak‑shift cost savings – Under peak‑valley electricity pricing, this system helps reduce expenditure by storing electricity during off‑peak troughs and using it during peak hours.
PV Solar Priority Mode
In this mode, the power supply to the load is provided by the solar panel input. The electricity generated by the solar cells is stored in the battery in addition to powering the user load. When the solar generation does not meet the user load, the stored battery power is used to supplement the load.
AC Priority Mode
In this mode, the power supply to the load is provided by the mains input. Solar power only charges the battery. When the battery power is seriously low, the AC mains will start to charge the battery. When the AC mains is powered off or abnormal, the system will switch to the battery to supply power to the load.
