The household solar power supply systems are mainly aimed at home users. With the maturity of solar energy technology and the decline in costs, solar power generation, which was originally only used in commercial and industrial fields, has been slowly extended to the civilian market. Compared with commercial electricity, household electricity demand is relatively small in terms of power generation and load, and the budget is limited. According to the current general household electrical appliances and electricity consumption, the 3KW-6KW power supply system will be the mainstream, and the daily power generation will be about 10KWH-18KWH, which can not only meet most of the electricity consumption, but also control the cost within an acceptable range.
The system is specially designed for high-power electrical appliances to ensure stable operation when the electrical appliances are turned on
at the same time.
Solar panels use cells with a conversion efficiency of up to 22%. The same number of solar panels will generate more power.
It provides two options of both lead-acid/gel batteries and lithium batteries, which can be chosen based on the system budget and using conditions flexibly.
The optional WIFI monitoring module can monitor the power generation and operation of the system through the mobile phone APP.

The off-grid solar PV system generally consists of a photovoltaic array composed of solar cell modules, solar charge and discharge controller, battery pack, off-grid inverter, DC load and AC load. The photovoltaic array converts solar energy into electric energy when there is light, and then supplies power to the load through the solar charge and discharge controller while charging the battery pack. When there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. Meanwhile, the battery also supplies power directly to the independent inverter, which inverts into AC power and supplies power to the AC load.
