  4kW off grid home solar power system




Off-Grid Solar Systems

When the utility power is unavailable or too expensive to bring in to your home or cabin, an off grid solar system allows you to be your own utility company! You can live in peace, with no noisy gas generator to disturb the quiet. Off-grid solar power stores DC electricity in batteries. The addition of an inverter allows this system to convert DC electrical current coming from the batteries into AC or alternating current to feed household appliances. 


Advantage of off-grid solar system: 

 -   Reliable electricity supply anytime day or night even without grid access

 -   Complete independence from external energy supply and electricity costs

1. Q: Are you a factory?
     A: Yes, welcome to visit our factory.

2. Q: Which size of solar system do you produce?
     A: We can produce different sizes from 100w to 100kw, both on grid and off grid.

3. Q: Can you design if we have any special requirement for the power consumption?
     A: Yes, we can. You can just let us know the power consumption of each day or month, and also the power of

     the main equipments you need to load.

4. Q: Where can we use the system?
     A: You can use our system for home, village, power station, office, communication station, lighting

     system, farm and so on, where there is no enough power or the grid power is expensive.

5. Q: What is the voltage of the system?

     A: We can adjust any voltage according to different countries or customers requirement, such as AC 110V,

     220V, 240V, 380V - 450V and so on, and DC 12V, 24V, 48V, 96V, 192V, 240V, 380V and so on.
