The TGP hybrid inverter drives the 4" brushless DC solar borehole motors (0.75kW to 2.2kW). It runs the pump directly from solar panels and can also take AC power (mains or generator) when there is not enough sun, so you are not left without water on cloudy days.
- Motor power range: 750W – 2200W
- Maximum PV open-circuit voltage: 450V
- Protection against under-voltage, over-voltage, overload and dry running
How many solar panels? (550W panels, as specified by the manufacturer)
- 0.75kW motor (110V): 3 panels
- 1.1kW motor (150V): 4 panels
- 1.5kW motor (200V): 6 panels
- 2.2kW motor (300V): 9 panels
This inverter is part of our 4SD TGP hybrid solar borehole kits – see the Solar Borehole Pumps category for complete kits matched to your borehole depth.
