Inverter Three-phase network SAJ R5-12K-T2 | Inverter Residential and Commercial Solar of 12KW with 2 MPPT

SAJ R5-12K-T2: Three-phase power of 12KW, MPPT Double Algorithm and Silent Refrigeration by Natural Convection

Covering the energy requirements of large housing or businesses with three-phase distribution networks requires high-end central equipment and excellent network management. The inverter networking SAJ R5-12K-T2 Three-phase 12kw it has been developed specifically to balance and optimally inject the energy captured on the roof, drastically reducing demand on the conventional network and ensuring efficient self-consumption in real time.

Double independent and high MPPT Overdimension margin

The competitive advantage of this 12KW model lies in the presence of its 2 independent MPPT followers. This configuration allows to group photovoltaic modules in two independent strings with different orientations or inclinations (for example, two waters and west waters) without the partial shading of a section of the efficiency of the other. Each follower manages a maximum input current of 12.5A. It is vital to remember that this device injects the electrical energy directly to the instantaneous consumption; If your project requires accumulation to be self-sufficient overnight, we advise you to opt for the models of our range of inverters hybrid with specific terminals for storage.

Also, the inverter admits a maximum recommended photovoltaic power in solar up to 18,000WP, Facilitating an intelligent oversizing the generation field. Thanks to this, the system is capable of rendering at maximum capacity even on days with low solar irradiation or cloudy days. If you want to explore options to configure a Solar Kit or incorporate chemical accumulation, you can review all available technologies in our general catalog of batteries lithium.

Industrial degree electrical protections and thermal dissipation without fans

Constructive robustness is the identity hall of the R5 series SAJ. This device stands out for a pressure melted housing chassis it ensures a prolonged durability against climate wear, endorsed by its IP65 insulation degree. In the Security section, it includes serial overvoltage protection devices (SPD) both on the DCTO Side and in the alternating current, together with advanced high-precision ground leakage monitoring systems. Its thermal dissipation completely dispenses with mechanical components as it is based on natural convection, achieving imperceptible performance with noises lower than Dba. To carry out the structural assembly and fixing your solar modules solidly on any roof, we recommend using our structures for of reinforced structural aluminum.

Frequently Asked Questions (FAQ)

1. What advantages does it provide to have 2 independent MPPT in this inverter three-phase 12kw? Dispose of 2 independent MPPT it gives you total freedom to divide the photovoltaic field into two independent sections. If a part of your it suffers from partial shades caused by trees, clouds or chimneys, or if they are mounted on two different roof skirts, the other MPPT follower's circuit will continue to yield at full capacity without generalized power falls.
2. The model SAJ R5-12K-T2 allows direct connection of lithium batteries? No, the inverters belonging to the series SAJ R5 Series are pure network connection equipment without native hybrid capacity. Its task is to transform the energy of photovoltaic plates and immediately inject local electricity consumption. In order to implement physical storage banks, you need to resort to a hybrid Inverter three-phase.
3. What noise level does this device emit during the hours of maximum production? The inverter offer operation completely silent, emitting a noise level lower than Dba. This is achieved thanks to the R5 series implements a sophisticated mechanism of natural Convection Refrigeration, Rightning attention to noisy mechanical fans that end up accumulating dirt or suffering failures by wear.
4. What security protections are integrated at the factory in the equipment? The equipment offers an extremely complete safety standard. Has overvoltage protection devices (SPD) in direct current and alternating current already pre-installed, Integrated thermal protection, automated anti-island monitoring and a high precision current leakage control sensor, shrinking the electrical network of your home or commercial premises.
