Solar Booster & Pressure
System Solution
Move stored water or hold a pressure in a line, with a system matched to flow and pressure demand. HOBER matches the booster pump, the solar pumping inverter and the PV configuration for distributors, installers and project companies.
A pump room installation
The system
From the Tank to the Line
A booster works against a pressure rather than a lift, and the array carries that duty.
-
Solar PV array Generates DC power from sunlight.
-
HOBER solar pumping inverter Controls pump operation and adapts to changing solar input. Control includes MPPT, soft start and soft stop, dry-run and level protection, system protection and optional remote monitoring where the model carries it.
-
Booster pump Lifts stored water into the line and holds it at pressure.
-
Pressure delivery The pipeline the pressure is held in, downstream of the pump.
The pump models, their figures and their curves are published with the range. The pump is matched into the system as a whole, together with the drive and the array.
Engineering challenge
Pressure Is the Duty
A booster set is read on the pressure it has to hold, not on the power of its motor.
A pressure duty is a control duty. The flow the line has to carry, the pressure it has to hold at the far end, the pressure the pump is fed at and the loss between them decide the duty point — and holding that pressure steady through a changing demand is what the drive and its pressure feedback are for. PID / constant pressure control is stated per model rather than across the range.
- Required flow The flow the line has to carry.
- Target pressure The pressure to hold at the far end of the line.
- Inlet pressure The pressure the pump is fed at.
- Elevation difference The lift from the tank or main to the highest draw-off.
- Pipeline length and diameter What the friction loss is read from.
- Pump and motor data The pump already on site and its nameplate.
Not sure about the head or the pressure?
The pipe friction loss calculator works out total dynamic head from the static head, the pipe friction loss and the fittings loss, and a pressure in bar converts to a head in metres.
Project data
Project Data We Need
The figures the pump, the drive and the array are matched on, and where each one is read.
The duty
- Required flow m³/h
- Target pressure bar at the far end of the line
- Inlet pressure bar at the pump, from the tank or main
- Operating hours h/day, and the hours of the day the pressure is wanted
The line
- Pipeline length m
- Pipe diameter mm or ″
- Elevation difference m to the highest draw-off
- Static head m from the lowest water level to the highest draw-off
The pump and the supply
- Pump already on site an existing set to keep, or a new selection
- Motor nameplate power, voltage, phase and rated current, or the nameplate photograph
- Power source solar only, solar + grid, or solar + generator
- Pressure feedback whether the line is read by a pressure sensor on site
System matching
From Project Data to System Matching
HOBER reads the flow, the pressure and the line against the range and matches the pump, the drive and the array to them.
- Project data
- HOBER matching
- The system
Example
Example project data
- Flow
- 12 m³/h
- Target pressure
- 4 bar
- Inlet pressure
- 0.5 bar
- Pipeline
- 180 m
The system the data resolves to
- Booster / inline pump
- Solar pumping inverter
- PV configuration
- System protection
The figures are an illustrative example of how a project is read, not a product claim: PID / constant pressure control is stated per model, so a line that has to hold a steady pressure is quoted on a model that carries it.
Product data

Support
System Matching Support Before Installation
The pump is only one part of a reliable booster system.
HOBER works on the system rather than the pump alone, from the project data to commissioning.

Booster and pressure projects
Have a Pressure or Booster Project?
Send the flow, the pressure the line has to hold and the pump the site runs. HOBER can help match the booster pump, the solar pumping inverter and the PV configuration for your project.
