On grid system
On grid systems are the most common solar PV installations
- The system is connected to the utility grid
- The solar panels generate direct current (DC)
- The inverter transforms direct current (DC) into alternating current (AC)
- Power first satisfies the connected load
- The excess power is exported to the grid
- Power is imported from the grid when the requirement is higher than the solar generation (or at night)
- No batteries are required
Off grid system
- The off grid system is 100% independent from the utility grid.
- It requires batteries
- The Charge controller protects the batteries from overcharging
- Inverter transforms direct current into alternating current power source
- Power is used for the dedicated load
- Excess power is stored in the battery bank for later domestic use
Hybrid solar system
- Connected to the utility grid and requires a battery bank
- The hybrid charge controller protects the batteries from overcharging
- A battery bank stores power for use when the grid isn’t available
- A hybrid inverter turns DC into AC
- Inverter satisfies dedicated load
- Excess power generated by solar exported to the grid
- A bi-directional meter calculates the net energy based on the import and the export
Water pumps
- Combined with solar panels
- Can run on both DC from solar panels and single phase power supply
- Various models are available with heads from 15 m to 120 m, according to your needs
- Voltage range from 30 to 300 VDC
- No batteries required
- Equipped with a sensor that protects the pump from a dry run
- Connected to a data logger to monitor your solar pump system (optional)
- Customized mounting structures for the solar PV modules
- The solar setup is designed according to your needs
