Reading of the photovoltaic meter


Aphotovoltaic meterallows us to understand how much 230 V electricity the photovoltaic system can produce. The electricity produced by our plant can be used for domestic needs, or fed into the national electricity grid, it is here that the photovoltaic meter.

What is the photovoltaic meter
Before introducing the energy produced by our plant into the national electricity grid, it is necessary that thephotovoltaic meterdetects the electricity sent and self-consumed so as to take advantage of the incentive rates or the exchange on the spot.

To monitor the energy produced, the self-consumed energy and that fed into the city electricity grid, thephotovoltaic meteruses a production device and an exchange device. TheEnel photovoltaic meter, for example, it provides users with various useful data such as:

  • the reading of the instantaneous power, i.e. the kilowatts drawn at that moment
  • the reading of the powers drawn and recorded by the meter
  • the reading of the power withdrawn in the current billing period for the previously identified bands
  • the reading of the power taken in the previous period (last reading).

How to read thephotovoltaic meter
There are two annexed to the solar systemphotovoltaic meters.The first is usually installed near the inverter and accounts for production. The other counter is thatbidirectionaland calculates the energy fed into the network and that withdrawn.

Practical example of thephotovoltaic meterof production
If a plant has a production capacity of 100 kwh, the production meter will report the electrical power produced at that moment which in the optimal case is 100 kwh. In the event of incentives, the kwh introduced into the network will be remunerated at an agreed rate.

Reading of the photovoltaic meter for the production:
A1, A2, A3 energy produced in the current month
A1, A2, A3 energy produced in the previous month
To understand how much energy has been produced it will be necessary to add the values ​​of A1 + A2 + A3.

Practical example of the photovoltaic meterbidirectional
The bidirectional meter can provide us with a useful reference to the amount of electricity we purchase from the grid when our photovoltaic system fails to satisfy our electric hunger (for example, at night) and also provides us with information on the amount of energy we put into the network.

Reading of the photovoltaic meter bidirectional:
A1, A2, A3 energy withdrawn in the current month
A1, A2, A3 energy withdrawn in the previous month
A1, A2, A3 energy injected in the current month
A1, A2, A3 energy injected in the previous month

In the event that the user benefits from a two-hour tariff, it will be necessary to take this into account when calculating the tariffs for energy withdrawn from the network.

Also in this case, to calculate the total, the values ​​A1, A2, A3 must be added.

Which of your appliances consumes the most?

If you were wondering how to read the enel meter to trace the real-time consumption of an electrical appliance, know that the enel meter is not the only way. A more reliable way to know the actual consumption of a device is to use a wattmeter, a device that can be bought in shopping malls at a price of 20-30 euros.

On Amazon, an efficient Power Consumption Meter is offered at a price of € 15.13 with free shipping. With this device it is possible to measure the electrical consumption of a single household appliance or of several devices connected to the Meter with a multi-socket.

The use is simple: just hook the appliance to this appliance and then fix it to the classic household electrical socket: on the device display will be identified electrical consumption in watts and an approximate conversion to economic consumption with the actual price of the electricity required by that appliance. device.
