From Diesel to New Energy: Redefining Off-Grid Power with an Integrated Storage & Inverter Solution

In remote areas, islands, mining sites, and for home backup power, traditional diesel generators have long served as the primary power source. However, high fuel transportation and operational costs, relentless noise, toxic exhaust emissions, and frequent maintenance have become a heavy burden for off-grid power supply. Especially in areas with poor transportation, any disruption in fuel supply can lead to an immediate power outage.

Is there a quieter, more economical, and more reliable alternative? Today, we bring you an integrated "Battery Box + Inverter" energy solution, delivering stable, low-cost, and clean power to places far from the grid.

The Breakthrough: Integrated Battery Box + Inverter Solution

EVCity’s "Battery Box + Inverter" combination perfectly demonstrates the synergy of "charging, storing, and converting." The battery box stores energy safely by charging via grid power, while the inverter efficiently converts it into 220V pure sine wave AC power to directly drive various household appliances, forming a stable and reliable independent power loop.

01 Core Storage: EVC-N02-2 LiFePO4 Battery Box

As the "energy heart" of the system, the EVCity battery box features a rated capacity of 4.02kWh and uses highly safe LiFePO4 (Lithium Iron Phosphate) cells.

• Smart Charging: Supports a Constant Current (CC) to Constant Voltage (CV) charging mode with a continuous charging current of up to 150A and a charging voltage between 14.2V and 14.6V. It is compatible with grid chargers and various charging methods for convenient and efficient power replenishment.
• Flexible Expansion: Supports up to 4 units in series, reaching a system voltage of 51.2V to easily meet different power demands.
• Modular Design: A game-changer tailored for remote areas! Without the need for heavy lifting equipment, a single battery box can be easily transported to remote islands via standard sea freight or small vessels, significantly lowering logistics and deployment barriers.

• 02 Efficient Conversion: EVC-N03-2 Pure Sine Wave Inverter

• Equipped with a fully digital CPU control, the EVCity pure sine wave inverter ensures stable and clean power output.
• Clean Output: Delivers 220VAC ±3V, 50Hz pure sine wave (THD < 3%) with a conversion efficiency of up to 92%~94%. This not only protects sensitive electronics but also minimizes energy loss.

• Multiple Specifications: Available in 12V (1-series), 24V (2-series), and 48V (4-series) battery voltage options for ultimate compatibility.
• Dual Assurance: Features dual battery inputs and dual 220V AC outputs, along with an LCD display for clear, at-a-glance monitoring of operating status.
• Comprehensive Protection: Built-in multiple protection mechanisms, including short circuit, overload, over-current, over-temperature, over-voltage, and reverse polarity protection, ensuring safe and reliable operation even in unattended, extreme environments.

• Versatile Applications: From Mining Lighthouses to Cozy RVs
• Mining Lighthouses / Remote Areas: Say goodbye to diesel forever. Take "1 lighthouse, 4 battery boxes, and a 51.2V system" as an example: it achieves 365 days of uninterrupted power supply with zero fuel transportation, saving tens of thousands of dollars in fuel and maintenance costs annually.

• Home Backup Power: Ensures seamless switching during unexpected outages, keeping critical loads like refrigerators, lighting, and medical equipment running without interruption.
• RVs / Campsites: The modular design allows for flexible installation. The pure sine wave output protects sensitive onboard electronics, and the completely silent operation lets you enjoy a pure outdoor lifestyle.
• From Diesel to New Energy: It’s More Than Just a Change in Power Supply.
  Whether injecting green power into remote infrastructure or adding peace of mind to your home, EVCity’s integrated "Battery Box + Inverter" solution provides you with quiet, reliable, and cost-effective power security.
