Irrigation
Field and orchard irrigation where the pump runs through the day and the water is stored or used as it is pumped.
Solar pump inverters
Built-in Booster Solar Pump Inverters
For sites where the inverter has to raise the voltage itself, because the array cannot be made long enough to reach the pump voltage directly.
0.75–2.2kW | Low PV Voltage Solution
01 / Quick selection
Narrow the range to the pump you have
Every model in this collection carries a built-in booster. A model whose specification states none belongs in the collection for its own pump supply.
No model matches this collection yet. Send the pump nameplate and we will confirm what fits.
02 / Key features
What every model in this collection is chosen on
- Every model states its pump voltage, pump phase and rated power, so a pump already on site leads straight to the model that drives it.
- The PV input window is given as a minimum, a maximum and the MPPT range, so the array is sized to the inverter rather than guessed.
- Hybrid AC input is stated per model, for sites that keep a grid or a generator alongside the array.
- Functions such as dry-run protection, water level control and remote monitoring are stated for a model only where it has them.
03 / Typical applications
Where this collection is asked for
Livestock and village supply
A daily water demand served from a well, a borehole or a tank, with storage sized around the pumping window.
Pressure boosting and networks
Pumping into a pressurised line or a distribution network where the pump is asked for a constant pressure.
Commercial and project pumping
Larger duties where the inverter is matched to a pump chosen for the duty, and the supply may be three-phase.
04 / System matching and PV sizing
The inverter follows the pump, and the array follows the inverter
The inverter is chosen from the pump, not the other way round. Send the pump nameplate and we will match it to the model that drives it.
- Pump voltage, pump phase and rated power decide which collection and which model apply.
- The array is then sized to the inverter's PV window, so the pumping hours follow the site rather than the catalogue.
- Where the array cannot reach the pump voltage directly, the built-in booster collection covers that supply.
The array, the inverter, the pump: the whole path is checked before a model is proposed
05 / Technical support
What to send so the answer is about your installation
Sizing, matching and after-sales questions are answered by the same team that supplies the inverter.
- A photograph of the pump nameplate, with the voltage, phase and power visible.
- The water source, the required flow and the total head, if the pump is not yet chosen.
- The array you have or plan, and whether a grid or generator stays available.
A nameplate photograph is usually enough to start
06 / Questions
Questions this collection answers
Which collection does my pump belong to?
It follows the pump supply: 220 V, 230 V or 240 V pumps belong to the 220 V collection, and three-phase pumps on 380 V, 400 V or 440 V belong to the 380–440 V collection.
Can one model appear under two collections?
Yes. A model that states a built-in booster and a 380–440 V pump supply belongs to both collections, because it is one product with two attributes rather than two products.
What if no model matches the pump I have?
Send the nameplate. For a pump outside the ranges we cover, we propose the closest model we can supply and state the difference, never a model that does not fit.
Can a low PV-voltage site use a booster, and which sizes have one?
Some HOBER inverters carry the booster inside the unit, and this collection is those models: it covers the 0.75–2.2 kW sizes, and a model belongs to the collection only where its specification states a built-in booster. A booster raises the array voltage the drive works at; it does not add energy, so the array still has to be able to supply the pump’s duty. An external add-on booster is a separate arrangement and nothing here implies one — send the motor data and the array you have, and the combination is checked against the selected model.

Not sure which model fits?
Send the pump nameplate and the site details. We will come back with the model, the array it needs and the supply it expects.
