Hybrid Inverter C & I all-in-one SAJ CHS2-29.9K-T4-X: Efficiency with 200% FV Oversignation, 280Ah cells and long-term industrial air conditioning

Efficient energy management in commercial complexes, farms or small factories requires compact systems but with a superior operating muscle. The model SAJ Chs2-29.9k-t4-x it represents a unified storage station that assumes the functions of photovoltaic generation, accumulation through high density lithium batteries and critical support in the face of fluctuations in the public network, directly decreasing demand peak charges and Optimizing schedule self-consumption.

High photovoltaic performance, 0.5C capacity and network flexibility

The continuous current architecture of the SAJ Chs2-29.9k-t4-x stopping when admitting a power in photovoltaic modules up to 59,800 WP (a 200% Overdimension regarding your Nominal AC). . This technical quality grants the system the ability to feed the active loads of the business building and, in parallel, to allocate the excess energy to recharge the battery of 57.3 kwh at a 0.5C transfer rate, ensuring efficient loading and unloading cycles.

Thanks to the internal integration of dry contacts, the electronics of SAJ allows you to go and enable external consumer loads, such as residential heat pumps or industrial air conditioning machinery, optimizing green energy consumption flows. . On the other hand, for those projects located in isolated environments or rural micro-grinding with unstable supplies, the equipment offers absolute compatibility for the direct access of external Gasoil generators, safeguarding the productive continuity of the business at all times.

Industrial air conditioning by air conditioning and active security

The storage heart of the CHS2 series is composed of industrial cells Iron and lithium phosphate (LifePO4) of 280Ah, free of cobalt and equipped with a high mechanical and chemical tolerance. . To avoid accelerated aging of the chemical compounds against intense summers, the closet has a robust system of air conditioning by dedicated air conditioning which stabilizes the temperature of the cells in a millimetric way.

The team is endowed with 6 levels of fire protection, with active mechanisms and rendering liabilities, in addition to a preventive supervision software connected to the cloud (Cloud bms) that reports alarms automatically before the slightest thermal or electrical variation anomalous. . The tower chassis has differentiated stannial certifications: protection IP55 for battery housing and IP66 protection for the upper block of the hybrid Inverter, allowing your safe disposition both in interior and weather rooms.

Frequently Asked Questions (FAQ)

1. For what type of facilities the model is recommended SAJ CHS2 of 29.9KW and 57.3KWh? By offering a nominal power of 29.9 KW of three-phase output and an intermediate storage of 57.3 kWh, it is optimally balanced for large single-family homes, neighborhood communities, medium commercial offices, local supermarkets, ships Storage and agricultural holdings looking for independence from the conventional network.
2. How does the all-in-one system respond if a generalized electric blackout occurs? The equipment has an automated switching functionality type UPS (Uninterruptible feeding system). If the electric network falls, the electronics of the inverter switches to emergency backup mode at a period of less than 10 milliseconds, maintaining computers, data servers or automatic refrigeration systems without appreciable cuts.
3. What technical maintenance does the air conditioner require that is integrated into the equipment? The closet is designed to minimize interventions in the field thanks to its high ip55 and IP66 environmental insulation rates. . However, when using an industrial air conditioning for the internal air conditioning of the batteries, it is advisable to carry out periodic cleaning inspections in the ventilation grilles to ensure a free circulation of the air and preserve the maximum cooling efficiency of the cells.
