1. What’s the difference between using a single inverter for the whole system and using microinverters?
Each type of inverter suits different conditions. Microinverters are ideal when panels have different orientations, partial shading during the day, or when you want module-level monitoring. They’re easier to connect but harder to maintain, as they are installed behind the panels and may require panel removal to access. Alternatively, optimizers can be used per panel.

2. If there’s a power outage, will I still have electricity because of the panels?
No, unless your system is designed for off-grid operation. In grid-tied systems, even though the panels still generate electricity, the inverter shuts down for safety reasons (islanding prevention).

3. And if I also have batteries? Will I still have power during a grid outage?
No, for the same reason as above. Your system must be specifically designed to work independently from the grid when there’s no voltage.

4. What kind of batteries can I install at home if I have a Huawei inverter?
The most common are lithium-ion batteries due to their long life, deep discharge, and low maintenance. It’s generally best to use a battery from the same brand as the inverter, as they’re better integrated. You could also use an AC-coupled battery that operates independently from the inverter.

5. Which solar panels are best?
Performance is quite standard across similar technologies (monocrystalline, polycrystalline, amorphous), but it’s important to consider size, available space, climate, durability, performance, warranty, insurance, price, and aesthetics to find the most suitable option.

6. What is a DAF and how can it help reduce reactive energy consumption?
A DAF is a power electronics device that eliminates reactive energy consumption. It’s useful when inductive reactive energy exceeds legal limits and results in energy bill penalties.

7. Why is using a DAF better than a capacitor bank?
Because capacitor banks have a short lifespan (usually under 5 years) even with maintenance. They also consume active power, potentially increasing your bill. They require manual adjustment to match reactive demand, and incorrect tuning can result in penalties for injecting capacitive reactive energy.

8. What is aerothermal energy and why is it more efficient than other heating/cooling systems?
Aerothermal technology uses heat pumps to extract energy from outdoor air to provide heating, cooling, and hot water. It works efficiently even in winter and can be powered by the grid or solar energy.

9. Can aerothermal systems be installed in apartments or only single-family homes?
They can be installed in apartments if there is enough space and community approval (especially if the façade is affected). Compact models without outdoor units are available.

10. Can I install a heat pump just for domestic hot water or only for heating/cooling?
Yes, there are models for each specific need.

11. Is the investment in a heat pump high? Is it worth it?
Initial costs are higher than traditional systems, but energy savings make it profitable in the medium term, even without subsidies.

12. Can I control it from my phone when I’m not home?
Yes, most modern models offer remote control via mobile apps.

13. How long does it take to pay off a heat pump?
It depends on energy usage and tariffs, but it usually pays for itself in 5–10 years through savings and available incentives.

14. Is it recommended for homes with poor insulation?
It works better in well-insulated homes, but it can be installed in any home — though energy consumption will be higher in poorly insulated ones.

15. Can I install an air-based climate system if I don’t have or want radiators?
Yes, fan coils or air conditioning units with heat pumps are viable options.

16. What happens if the outdoor unit fluid freezes?
Modern systems include automatic defrost functions to prevent freezing.

17. How does aerothermal heating affect indoor humidity?
It doesn’t affect humidity, but when used for cooling via radiant floors, condensation control might be needed in humid climates.

18. Is it compatible with pellet or wood heating systems?
Yes, both systems can be combined to improve efficiency and reduce costs during high-demand periods.

19. How long does a heat pump last before needing replacement?
With proper maintenance, a heat pump typically lasts 15–20 years
