Self-Consumption Photovoltaic Panels (Grid Connection three-phase meter)

9.164,56 29.400,00  inc. IVA

In Growatt self-consumption systems, the MOD range corresponds to hybrid inverter models that work as a classic grid connection inverter that also has the possibility of accumulating surplus photovoltaic production in Growatt ARK batteries.

You can have a system that directly contributes the energy produced by solar panels to electricity consumption in real time. If the production is higher than the consumption, energy will be used to charge the battery so that it can contribute at times of low production or at night. Growatt’s MIN and MOD series of grid-connected inverters have single-phase and three-phase options, although both series now work with high-voltage batteries and come with a BMS for communication between the inverter and each battery module. It is an economical installation, given the characteristics that such an installation can provide us.

We can also offer you single-phase systems or autonomous isolated installations, as well as provide you with a custom solution to fit your conditions, contact us

Description

Summary

System

  • Our self-consumption installation can be started with the hybrid inverter and the panels. In the future it can be complemented with accumulation in batteries, in case our consumption pattern does not coincide mainly with the hours of greatest production. The energy that the panels have provided in hours of sunlight, we will have it stored so that we can use it at another time, reducing to the maximum the use of energy from the electrical network. We can gradually add modules to suit our needs without making a large initial investment.
  • The Growatt inverter is interconnected with the electrical grid, so it must always be available, and the energy produced by the panels is injected as our first priority for consumption. However, it integrates an EPS emergency supply function that can generate an auxiliary network if the electrical network falls and can supply us from the sun and batteries. For this, a contactor is necessary as a complement.
  • With this system we will reduce our billing because our electrical installation will make use of solar energy as a first priority, and according to our preferences also the battery before the electrical network. All this is imperceptible to the use since we will not notice absolutely nothing when all the energy sources are being combined or we only supply ourselves with solar energy.
  • In these facilities the amortisation time increases due to the cost of the battery or if we have a system without accumulation, although thanks to the high number of battery life cycles and not requiring any maintenance, they can be very interesting and profitable depending of our consumption profile. It is highly recommended to have an hourly discrimination rate that reduces the cost of energy that we consume outside the hours of solar production, so we can even charge the battery from the network if there are several days of bad weather in hours in which energy is more economical.
  • There are three-phase models from the Growatt MOD range between 6000 and 10000W. You will be able to see in the manufacturer’s app from your smartphone and also from the web portal your graphs of production, savings and overall performance of your solar installation. One of the main qualities of the MOD range is that they incorporate first-rate features and great performance for the price they have, in fact the wattmeter is integrated and the toroidal sensor is included, and you can also give connectivity to the inverter both wired as wifi with its corresponding accessories. In a photovoltaic kit we will include all the necessary components for a perfect operation.

Growatt ARK 2.5H-A1 Lithium Battery

This high voltage battery module is suitable for self-consumption Growatt systems that use the battery for surplus storage. This lithium accumulator provides a long service life and can be supplemented with more 2.56kWh modules to increase the capacity of our battery bank. With an extensive warranty and more than 6000 cycles of use, the Growatt ARK batteries for self-consumption are a reliable and durable bet for our solar installation. It comes bundled with the Growatt ARK BMS.

The Growatt ARK BDC 95045-A1 Lithium Battery BMS controller is suitable for use in an ARK XH system, compatible with Growatt MIN-XH and MOD-XH inverters. It communicates with the inverter and manages charging and discharging of connected modules.

Technical Data Sheet

Growatt MOD 6000-10000TL3-XH

They incorporate a double MPPT tracker with a working range of between 160 and 1000V, whose function is to obtain the maximum efficiency of the solar panels. It is perfect for when we have the solar panels installed from our direct solar self-consumption installation in different positions, such as on a gabled roof of a house or with different electrical characteristics. It is indicated to work connected to triphasic networks with 3 phases and neutral.

These types of inverters are perfect for residential or domestic installations, as they are capable of withstanding a wide range of input voltage from solar panels and start up with very little initial voltage. If we wish, 48V batteries can be connected to store the excess production that we do not use and take advantage of it at times of low production or at night.

In addition, it incorporates an emergency supply provision when the electrical network fails to provide energy from batteries and solar production. The inverter has a 5-year warranty, very compact dimensions and very complete remote monitoring. Without moving parts or fans that make noise, it is also a guarantee of reliability.

Technical Data Sheet

Weidmuller PV Stick Connectors

They are a type of connector that does not require any tools to be able to assemble it with the cable, they are very useful since they have compatibility with the connectors that the vast majority of solar panels carry as standard, the MC4 connectors. We only have to strip the cable approximately 1.5cm and insert it through the hole of the connector.

Once introduced, we must strongly press the connector with the cable inwards until a click is heard. At this time we will know that the connector has been properly installed because if we pull the cable it will no longer come out. The cables compatible with the Weidmuller PV Stick connector are from 4mm2 to 10mm2.

Structure on Metal Cover KH915

The structure on metal roof that we offer in the kit is special to be fixed on any coplanar surface, be it in an industrial warehouse or private home that has a sloping roof. The structure has all the certificates and load regulations. The orientation of the roof must be south to avoid losses. The structure includes an assembly manual for the structure as well as all the necessary hardware to anchor the solar panels to it. In the event that another type of structure is required on facades or on the ground, contact us to be able to offer it.

System Legalization

We offer photovoltaic installations legalization service for the panels that are connected to the electricity grid, provided that the installation and / or start-up has been carried out by our professional team, as it is an essential requirement according to current regulations that these installations have been carried out by an authorized installation company, such as ENERA. Legalization is essential so that you can pour into the electricity grid and sell the excess energy in compliance with Real Decreto 244/2019.

To proceed with the legalization of the photovoltaic grid connection system, it is essential that the system has the appropriate protections. You must purchase the protections separately, contact us for more information.

Prior to the legalization of the installation, a visit must be made by an ENERA technician.

Documentation
The documentation included in the price of installations up to 10kW is:

  • Processing of the Electrical Installation Certificate.
  • Technical memory/data.
  • Rates and registrations.

We do not provide you with other information that, although it may be related to the legalization of solar installation, is not essential for its management.
