The nameplate
Voltage, phase and rated current, read from the plate on the motor. This is where the check starts.
AC Pump Conversion
Keep your pump.
Change its power.
Add solar capability to a compatible existing AC pump instead of replacing the pump. We check the motor and the application before recommending an inverter and a PV configuration.

01 / The idea
The pump stays.
The way it is driven changes.
A conversion keeps the pump that is already installed and changes the energy behind it. The motor is fed by a solar pump inverter instead of the existing supply.
- The PV array feeds a HOBER solar pump inverter.
- The inverter drives the existing AC motor.
- The pump itself is not replaced.
- Grid or generator backup is used where a suitable hybrid model is selected.
- Protections and pump-specific controls belong to the inverter, not to the pump.
02 / What has to be checked
The motor, the pump, the array.
Then the installation.
A conversion is decided on the equipment and the site, not on a product list. These are the points our team works through with you.
The pump and its duty
The pump type and the application it serves — the water it moves and the way the installation is used.
The array
Module data and the string design, so the array and the inverter are considered together rather than apart.
The site itself
The cable run, an output filter or reactor where the run calls for one, and the environment the equipment sits in.
These points are reviewed together. The outcome is a confirmed configuration for your site, not an assumption about it.
03 / What to send
Send the details.
The check starts there.
These are the details that make a compatibility check possible, whether the pump is on site or still on the drawing board.
- Motor nameplate details, or a clear photo of the plate
- The pump model and the application it serves
- The water source and the duty the pump has to meet
- The site location
- Whether grid or generator backup is available at the site
A compatibility check starts from these details. Send what you have, and we come back with the configuration that fits the motor and the site — or with a straight answer if a conversion is not the right route.

04 / Where it is not the answer
Some pumps should not
be converted.
Not every motor is suitable for a solar conversion. The nameplate details and the way the pump is used decide whether an inverter can drive it, and that is reviewed before anything is proposed.
A pump that is worn, mismatched or outside what the inverter can drive is not a conversion project. We say so, and we look at the pump range with you instead.
An early straight answer is part of the service. An inverter that cannot run the existing pump helps nobody, and we would rather discuss the alternatives than propose one.
Next step
Send the nameplate.
We check the motor.
Share the motor and site details and our sales team reviews the conversion. The answer is a checked configuration, or an honest note that the pump is better replaced.
