8KW off grid solar power system for home use with battery

Off-grid photovoltaic power generation system is widely used in remote mountainous areas, no electricity areas, islands, communications and street lighting applications. The system is generally composed of photovoltaic square array composed of solar cell modules, solar charge and discharge controller, battery bank, off-grid inverter, DC load and AC load, etc. The photovoltaic array converts solar energy into electric energy under the condition of light, and supplies power to the load through the solar charge and discharge controller, and charges the battery bank at the same time. In the absence of light, the battery bank supplies power to the DC load through the solar charge and discharge controller. At the same time, the battery directly supplies power to the independent inverter, and the independent inverter converts AC power to the AC load

A complete list of materials required for a off-grid 8000w solar PV system

Design of off-grid photovoltaic power generation:

  1.  Determine the rated power of the off-grid inverter according to the load size and type, whether it is single-phase 220V or three-phase 380V;
  2. Determine the size of the energy storage battery (such as how many KWH to store) according to the discharge duration of the energy storage battery required by the load;
  3. According to the load power consumption (how many kilowatt-hours) and the local sunshine conditions, select the board with more power;
  4. Select the size of the corresponding charge controller according to the size of the PV panel and battery voltage; 5) Support cables and so on (the installation site is the roof or the ground).

How the off grid solar system working?

This 8kw off grid solar system not only have solar power system function, but also have Utility complementary function. When main power off , the solar system can switch automatically to take use off solar power from battery to run load, When solar power not enough and power off , it can switch automatically to main power and connect with grid electricity take use of main power, at the same time charging battery. This is very suit for home use.

What’s the difference between off grid and on grid solar power system?

Off-grid solar power system doesn’t connect to the power grid. In general, it includes solar panels, charger controller, batteries and inverter. This system will store the solar power into the batteries, batteries energy will be converted the electricity power to supply the appliances working through the inverter.
On-grid solar power system connects to the power grid, can sell excess electricity to the public grid. In general, it includes solar panels, grid-tie inverter, the solar power will be converted the electricity power to appliance working directly. When the solar power is off, the power grid will replenish the electricity power to appliances working.

What is the estimated power production?

Assuming peak sunlight hours in your area of 5, a 6 kW solar system panel is estimated to produce 30 kilowatt hours (kWh) per day.Learn more by reading calculate solar system size
