This three-phase self-consumption kit with zero discharge grid allows the generation and consumption of electricity during daylight hours. The zero discharge grid self-consumption kit allows saving on electricity bills, achieving considerable annual savings. Solar panels and zero discharge grid self-consumption kit are the best option to start with renewable energy.

This Kit is the solution to generate great savings, made up of solar panels and a zero discharge grid injection self-consumption inverter.


This Kit gives us approximately 12Kw / hour of energy for savings, making a calculation per day in winter about 4 hours gives us 48000w / day of savings and in summer about 7 hours 84000w / day of savings.


The GridFree inverter with limiter is a revolutionary solution for domestic solar installations that works in a similar way to other GridFree microinverters, but is capable of reducing its own production according to the current consumption of the house and thus completely avoiding overflows to the public grid .


Zero discharge network self-consumption kit installation


In Wccsolar, the installation of this zero discharge grid self-consumption kit is recommended that it be installed by a photovoltaic professional, or the installation instructions be strictly followed to avoid bad connections and breakdowns due to incorrect installation.


This Solar Kit is compatible with the following structures:

Perforating Roof Structures are designed to install in a horizontal position, with the same inclination as the existing roof. Vertical installation is also possible, forming a vertical column. Designed to withstand loads such as snow and wind, made entirely of high quality aluminum, while the hardware and accessories are made of stainless steel.

Sheet metal sandwich roof structures with special anchors for sheet metal roofs. This structure is made of aluminum and maintains the same inclination of the deck or roof where it is installed. It is a universal structure that adapts to any brand of plate. Its installation is simple and does not require technical knowledge.

Structures Flat or low inclination designed to be able to anchor the solar panels to the ground, either on a flat roof on top of a building or on the ground, we have various inclination angles to be able to adapt all the structures to the needs that arise in each case.

Characteristics of the SUN-12Kw Three-phase 380v Inverter


Self-consumption inverter SUN-12Kw Red 12Kw has 2 MPPT trackers, which means that we can have 2 different orientations for our photovoltaic field without harming the production of one over the other. The SUN-12Kw Red 12Kw Self-Consumption Inverter has an extremely low starting range for its internal regulator. The working range of your regulator is between 220V and 850V, so with 8 panels of 72 cells you can start up. It has a high limit on its working voltage, so we can use any type of panel as long as we respect the ranges defined by the manufacturer.


This inverter has an integrated signal repeater that allows communication between inverters thanks to the fact that the Wi-Fi signal is transferred from one SUN-12Kw Self-consumption inverter to another. This is very interesting for large photovoltaic installations that require several inverters and that otherwise would limit communication between them.

This inverter is compatible with the Chint single-phase wattmeter to confirm compatibility with other wattmeters, contact us or consult the technical sheet in each case.

The SUN-12Kw Red 12Kw Self-consumption inverter offers high operating efficiency of more than 98% and has the best expansion capabilities at the best price. Even being a grid connection inverter.
