What is a photovoltaic investor and how does your bill optimize?
Technically, the inverter it is a static power converter. Its primary function is the switching of the current, but the equipment of Tienda Solar they go much further. Modern investors act as intelligent energy managers:
-
Network synchronization: In milliseconds, the inverter equalize the wave of your panels with that of the electrical network so that the consumption is invisible and fluid.
-
MPPT follow-up (MAXIMUM POWER POINT TRACKING): It is the algorithm that "tracks" the maximum power point of your plates, adjusting the tension to extract until the last watt, even on cloudy days.
-
Active security: They include protections against electric arcs, overvoltages and the "anti-island" system, which disconnects export if the external network falls, protecting maintenance technicians.
Types of Solar Investors: Classification by application
To choose correctly, we must first identify the nature of your project. On Tienda Solar we divide our range into four great families:
1. Network connection inverters (on-grid)
They are the most common in urban nuclei. Your goal is the direct savings. They do not usually take batteries (although many new models are already "Battery Ready").
-
Strong point: Simple installation and ROI (investment return) faster.
-
Featured brands: Fronius, , SMA, , Huawei.
2. Hybrid investors (the Standard of the Future)
The most versatile solution. They can simultaneously manage panels, lithium batteries and the electrical network.
-
Backup function: If the light is going, the inverter hybrid switches to batteries in less than 20ms, keeping your house with energy.
-
Featured brands: Deye, , Huawei Moon, GoodWe, SOLAX.
3. Isolated Inverters and Charging Investors (OFF-GRID)
Designed for places where the network does not arrive. These teams generate their own alternate network from a battery bank (12V, 24V or 48V). Models chargers they also allow connecting a gasoline generator or diesel to load the batteries in emergencies.
-
Featured brands: Victron Energy, Studer, Must.
4. Microinverters and optimizers
Unlike chain inverters (string), these panel panel installed.
-
Advantage: If a panel has a shadow, the rest of the installation continues to produce 100%. Ideal for roofs with fireplaces or shadows of trees.
-
Featured brands: ENPHASE, APSYSTEMS.
Critical selection factors: what they do not always tell you
For a professional design, in Tienda Solar we recommend looking at these parameters that mark the difference between a standard system and one of high performance:
The Overdimension Ratio (DC / AC)
Is a common mistake to think that a inverter 5KW can only take 5KW in panels. Most manufacturers allow a overdimensioning from 30% to 50% (Ratio 1.5). This means that you can install 7.5kwp in panels in a inverter 5KW to produce to the maximum during the hours of low radiation (morning and afternoon).
Number of MPpts and input current
With the arrival of high-power panels (+ 550W), the current (amps) has risen. It is vital to verify that the inverter support 15A or 20A per entry to avoid "clipping" or loss of energy. In addition, having 2 or 3 MPpts allows panel to be paneled in different roofs (north, south, east) without affecting each other.
Degree of protection and location
Always look for equipment with certification IP65 or IP66. This guarantees that the inverter it is sealed and can be installed on the outside. However, remember: heat is the enemy of electronics. On Tienda Solar we always advise the installation in the shade to avoid the derating (Range of power due to excess temperature).
Comparative Table: Investor Technologies
| Feature | Network investor | Hybrid investor | Isolated investor | Microinversor |
| Battery use | No (usually) | Yes (lithium / lead) | Mandatory | No (usually) |
| Cutout | Turns off | Keep working | It always works | Turns off |
| Installation | Very simple | Average | Complex | Panel |
| Efficiency | + 98% | + 97% | + 94% | + 96% |
Monitoring: your solar plant in the palm of the hand
A inverter modern without connectivity is a blind team. On Tienda Solar, all our investors include (or allow add) WiFi / LAN / 4G modules. Through apps as FusionSolar (Huawei) or VRM Port (Victron), you can see:
-
Daily, monthly and annual production.
-
Real consumption of your home.
-
State of charge of the battery (SOC).
-
Economic savings and reduction of CO2 emissions.
Frequently Asked Questions (FAQ) on Solar Investors
1. How long does a inverter solar?
The average life is 10 to 12 years. The microinverters can reach 25 years. On Tienda Solar, We offer guarantee extensions for your investment to be protected during the entire amortization period.
2. What is high frequency noise?
Some investors use fans to refrigerate, which generates noise. If you are going to install it near a bedroom, choose models of natural refrigeration (passive) as Huawei or Fronius Primo, which are practically silent.
3. Can I put a inverter three-phase in a single-phase house?
No. You must respect the type of installation of your home. A inverter three-phase will not work if it does not detect the three phases of the electrical network.
4. What happens if my inverter it breaks down?
It is the most sensitive component. For that, in Tienda Solar we manage guarantees directly with manufacturers to ensure that the downtime of your plant is minimal.
