FAQ
FAQ – HOBER Smart Quote System
Common questions from distributors and installers when using the online sizing and quotation tool.
What information do I need to get an accurate solar pump system quote?
To generate an accurate configuration, please provide:
- Water source: well / borehole / river / pond
- Total head (m)
- Required flow (m³/h)
- Pump model (if you already have a pump)
- Preferred mode: solar-only or hybrid (solar + AC / grid / generator)
The system will then calculate the suitable pump, inverter, solar panels and key accessories.
Can I add my own profit margin or installation fee?
Yes. You can enter your installation fee and profit margin before generating the PDF.
The final quotation will show your selling price with markup, so you can share it directly with your client under your own company name.
What if my pump model is not in the list?
If your pump model is not listed, please:
- Choose “Existing Pump” mode in the tool
- Select the closest power range
- Enter pump name, power, voltage and head manually
If you are unsure, you can send the pump nameplate or photo to HOBER via WhatsApp. Our engineer team will double-check the configuration for you.
Does this tool support both DC and AC water pumps?
Yes. HOBER inverters can work with:
- DC BLDC solar pumps
- AC submersible pumps
- AC surface and centrifugal pumps
For hybrid projects, HOBER hybrid inverters can accept DC from solar and AC input at the same time. AC is not converted into a separate DC output like many traditional “hybrid” inverters on the market – it is designed specifically for driving water pumps with simultaneous AC + DC input support.
How accurate is the solar panel sizing from this tool?
The PV sizing is based on typical solar radiation, pump efficiency and MPPT performance from real projects in Africa and Southeast Asia.
For most small and medium systems, the sizing is very close to real field results. For large projects or special conditions, we recommend sending full site data to HOBER so our engineers can fine-tune the design.
Can I export the quotation as a PDF with my company name?
Yes. You can input your company name, client name and quote number at the top of the form.
The system will generate a clean, professional PDF quotation that you can send directly to your customer or print for project files.
FAQ – Installation & Troubleshooting
Practical guidance for installers working with HOBER solar pump inverters and systems.
How do I calculate the total head (Total Dynamic Head) for my system?
Total head consists of three parts:
- Static head: vertical height difference between water source and delivery point
- Friction loss (hf): loss caused by pipe length, diameter and flow speed
- Local resistance (hj): loss from elbows, valves, tees, filters, etc.
Formula: TDH = Static Head + hf + hj
If you are unsure, send us the pipe length and diameter. Our team can calculate it for you.
How far can I place the solar panels from the pump inverter?
For best efficiency:
- DC side distance is recommended < 30–40 m
- If longer distance is necessary, use proper cable and protection design
- Avoid unnecessary joints, bends or shaded paths
For large systems, contact HOBER for detailed wiring and protection advice.
Why do I need a reactor in the system and what does it do?
A reactor (AC or output line reactor) is used to improve reliability and protection of the pump system, especially on higher power or long cable runs. It can:
- Reduce harmonic current and voltage spikes from the inverter
- Protect the motor insulation and extend motor lifetime
- Smooth the output current and reduce noise and vibration
- Help protect the inverter when the cable between inverter and motor is very long
For larger power pumps or long-distance motor cables, HOBER strongly recommends using a reactor as shown in the wiring diagram.
Can HOBER inverters start a pump when sunlight is weak or cloudy?
Yes. HOBER uses advanced MPPT and soft-start technology. In weak sunlight, the inverter will:
- Reduce pump speed
- Maintain stable operation as long as voltage and power are sufficient
- Prevent low-voltage shutdown and frequent restarts
This ensures water output even during cloudy conditions.
Can I connect both AC grid or generator together with solar panels?
Yes. For HOBER hybrid models, the inverter allows DC solar input and AC input to be connected at the same time.
Connection:
- Solar panels → PV (DC) input
- Grid or generator → AC input
During operation, the inverter uses solar energy as priority and AC power as support or backup. It is designed for simultaneous AC + DC supply to the pump, not as a traditional AC-to-DC conversion inverter.
What are the most common installation mistakes to avoid?
The most common issues are:
- Poor grounding or no grounding
- Wrong panel series/parallel connection
- Installing panels under shading
- Pump running dry (no water)
- Incorrect motor wiring
Following HOBER’s installation guide can eliminate most of these problems.
What should I do if the pump stops during operation?
First check the following:
- Solar panel connections and PV voltage on the inverter display
- Whether the water tank is full (float switch active)
- Motor overload or dry-run protection alarm
- AC/grid or generator status if you are in hybrid mode
If the issue continues, contact HOBER with photos or a short video for quick diagnosis.
