We provide residential or small commercial solar system suitable for homes, offices, schools, small or medium size buildings that want uninterrupted power supply, reduced utility bills or that want to be electrical power independent. The system generates power from the solar panels as a standalone off-grid system to charge the batteries and supply power to the load. Also, the system is an uninterrupted power supply (UPS) where the system is connected to the public grid when available and immediately takes over to supply the load when loss of grid power. The size of the system depends on the size of the load or power consumption required by the client. A typical residential system is between 1.5kVA to 30kVA.
