The SAKO E SUN 4.2KVA 24V Off Grid Hybrid Inverter represents the definitive pinnacle of hybrid power technology, expertly engineered to provide seamless, reliable, and high-capacity electrical backup. Classified as a multi-function inverter/charger, this unit skill fully combines the indispensable roles of a robust inverter, an intelligent MPPT solar charge controller, and a versatile battery charger into one robust, compact, and aesthetically pleasing chassis. It is the ideal, high-capacity solution for larger residential settings, demanding small office environments, or light commercial operations in regions, like Bangladesh, characterized by inconsistent utility power and a growing reliance on renewable energy sources. This model’s powerful output and advanced features solidify its position as a top-tier choice for securing energy independence.
High Capacity and Pure Sine Wave Output (4.2KVA / 3500W)
This specific model delivers a formidable continuous power output of 4.2KVA / 3500W while operating on an efficient 24V DC battery system. This higher voltage configuration is optimally suited for minimizing internal current draw, significantly reducing losses across cables, and maximizing overall system efficiency in high-power applications. This robust capacity ensures that you can power a wide array of appliances simultaneously—from standard lighting and fans to energy-intensive equipment such as dedicated AC units (within capacity limits), refrigerators, and water pumps.
Crucially, the output is strictly Pure Sine Wave. This means the electricity generated is clean, stable, and perfectly identical in quality to that supplied by the public utility grid. This uncompromising power quality is vital for safeguarding all connected appliances, particularly sensitive electronics (like computers, modern televisions, and diagnostic equipment) and high-inductance motor loads. Using Pure Sine Wave power protects these valuable assets from the operational stress, overheating, and damage often associated with the less refined output of modified sine wave inverters, thereby extending their operational lifespan and minimizing replacement costs.
Revolutionizing Energy Harvest with Advanced MPPT Technology
The core of the SAKO E-SUN 4.2KVA’s high solar efficiency is the integrated Maximum Power Point Tracking (MPPT) solar charge controller. This technology represents a significant leap over older Pulse Width Modulation (PWM) methods. The MPPT controller constantly scans the photovoltaic (PV) array’s electrical characteristics to precisely locate and operate at the point where maximum power can be extracted, ensuring an impressive efficiency rate that often exceeds 98%. This results in you harvesting more power from your solar panels throughout the day.
The unit boasts a remarkably Wide PV Input Range of 45Vdc to 450Vdc granting substantial flexibility in solar array design. This wide range simplifies installation and allows for more cost-effective string sizing across rooftops of varying sizes and orientations. A vital feature for maximizing power yield during marginal hours is its low start-up capability: the inverter is designed so that Only 1pcs 36V solar panel can start the solar inverter, guaranteeing effective charging initiation even under minimal solar irradiance or during the challenging transition periods of dawn and dusk. This maximized daily energy yield directly translates into faster battery charging and greater long-term operational cost savings.
Intelligent Customization and Versatile Battery Integration
The SAKO E-SUN 3.0KW is designed for modern users who demand precise, granular control over their energy usage. Control over the system is managed through a comprehensive LCD display and user-friendly control buttons. This interface allows for highly personalized energy management settings:
Configurable Charger Priority: Users can easily set the system to prioritize charging from the solar array (maximizing the use of free, renewable energy) or revert to using the AC utility/generator source (ensuring the batteries are always topped up).
Battery Chemistry Compatibility: Utilizing a smart battery charger design, the unit is fully compatible with a diverse range of battery chemistries, including traditional flooded, AGM, and Gel batteries, as well as the powerful and long-lasting Lithium-ion (LiFePo4) batteries. This future-proof compatibility ensures the system remains relevant as energy storage technology advances.
Adjustable Charging Current: The charging current can be precisely configured to optimally match the specific capacity and health of the connected battery bank, a feature crucial for optimizing battery health and extending its service life.
Input Range Flexibility: The unit allows users to set different acceptable AC input voltage ranges for either sensitive loads (UPS Mode) or standard appliances, tailoring protection precisely to the load requirement.
Uncompromising Reliability, Safety, and Connectivity
Reliability is a cornerstone of the SAKO E-SUN 4.2KVA’s design. The system is engineered to seamlessly manage power input from both the mains utility and a generator, providing flexible and reliable options for battery replenishment.
Safety is paramount, with comprehensive features built in:
Protection Suite: Integrated safeguards against Overload, Over temperature, and Short circuit protection ensure both the longevity of the inverter and the safety of all connected loads.
Operational Continuity: Key features include Auto restart while AC is recovering for hands-free transition back to grid power, and a Cold Start function, which allows the inverter to be powered on directly from the batteries even when no external AC input is present.
Optional Monitoring: For sophisticated users, the SAKO E SUN 4.2KVA supports optional WIFI/GPRS monitoring, enabling remote access to system status, historical data, and setting adjustments via a smartphone or PC, providing unparalleled oversight of your power system.
