Hybrid Inverter Three-phase SAJ 20kw H2-20K-T3 | Pack AIO3 + Meter + CT

SAJ H2-20K-T3 AIO3: maximum three-phase self-consumption of 20kw, current by 20A string and active ACCI security

Covering the electrical needs of large residences with extreme consumption or industrial warehouses requires a robust, intelligent and high response control center. The hybrid Inverter networking SAJ 20KW H2-20K-T3 it has been developed specifically for this purpose, acting as the analytical heart of photovoltaic installation by simultaneously synchronizing photovoltaic uptake, active property loads and energy storage.

20A Extreme FV Support by chain and mass storage capacity

The main competitive advantage of this model of the T3 series resides in its electric tolerance in continuous current. His tickets assimilate a maximum current by 20A chain, an indispensable parameter at present to operate optimally with the solar of last generation large cells. By enabling a photovoltaic oversizing up to 200%, this inverter three-phase allows you to connect up to 45,000WP in the roof modules, ensuring a constant mass production and battery charge even on very cloudy days. If you want to explore alternatives from different powers within the same brand, you can check our full catalog of inverters hybrid high voltage, as well as other types of inverters like inverters networking or microinverters, Ideally for balcony Solar Kits!

This set comes equipped from the factory with the ecosystem AIO3, the meter (vatimeter) and the three-phase current transformers (CT). These advanced sensors measure the electric flow between the public network and property, allowing activating effective zero injection strategies or asymmetric phase rolling. All the clean energy produced that you do not consume at the moment can be quickly directed towards a lithium storage bench, available in our category dedicated to stationary solar batteries, achieving a full self-consumption overnight.

Energy continuity UPS ≤20ms and intelligent high power cooling

The protection of computer equipment and critical machinery is guaranteed thanks to its emergency backup function UPS, with a switching time ≤20 ms. In case of an unexpected section in the outer electric network, the inverter react autonomously by maintaining the three-phase supply without harmful interruptions. Security is complemented by integrated AFCI detection technology, which monitors CC lines to extinguish electric arc failures before they become fire risks. To withstand the great energy flow of its 20kw, it incorporates a system of intelligent cooling by fan and protections of type II overload. At the time of definitively anchoring a high volume of on your industrial or residential cover, we suggest you use our structures for aluminum reinforced with high wind resistance.

Frequently Asked Questions (FAQ)

1. What real advantages does this model admit a 200% oversizing in cc? Allows you to connect up to a maximum solar field of 45,000WP in Solar Plates. This ensures that the inverter work at maximum nominal capacity of 20KW for many more hours a day, optimizing generation in the early hours of the morning, late afternoon, or during winter days with low solar radiation.
2. What do you use the input and the CT included in this 20KW pack? It is the devices responsible for performing the bidirectional reading of the current at the general rushing point of the three phases. Send constant readings at inverter in order for this to decide whether to inject photovoltaic surpluses to the batteries, if it covers the asymmetric internal consumption of each phase or if it executes a strict zero injection to do not pour anything to the network.
3. How does the integrated ACCI arc failure switch act? The system AFCI is an integrated digital active protection. Use algorithms to scan the lines of solar and detect the characteristic frequencies of electric arcs (caused by peeled cables, loose connectors or humidity). By identifying it, the inverter cut production instantly to neutralize any thermal risk.
4. What kind of maintenance or care does your ventilation system require? Due to the great power of 20kw that processes, the inverter incorporates a system of intelligent cooling by fan. The inverter it regulates the speed of the automatic fans based on the actual temperature of internal electronics, optimizing the air flow, protecting the components against thermal stress and minimizing the particle entry.
