Seamless Off-Grid & On-Grid Adaptation: EVCity 6.5kW/12kW Hybrid Solar Inverter — Redefining Resilience in Solar-Storage Systems

In PV and energy storage applications, grid instability and power outage risks are the core challenges limiting system reliability. Ensuring seamless transition between on-grid and off-grid operation has always been a key technical focus for EVCity.

To address this, EVCity introduces the 6.5kW/12kW Hybrid Solar Inverter, built around the core design philosophy of "off-grid + on-grid adaptability." It integrates PV input, MPPT tracking, DC-AC inversion, and energy storage management into a single unit. With exceptional switching performance and flexible networking capabilities, it delivers uninterrupted power supply for end users and empowers partners to build highly competitive solar-storage solutions.

01 High-Precision MPPT Tracking for Efficient PV Integration

The EVCity Hybrid Solar Inverter features an intelligent MPPT algorithm that continuously tracks the maximum power point of the PV array, maximizing energy harvest under complex irradiance and off-grid conditions — ensuring every ray of sunlight is efficiently converted into usable power.

• Efficient PV Integration: Compatible with mainstream large-format modules of 580W / 640W / 720W, with optimized DC-side input that maintains strong generation gains even in off-grid mode.
• Multi-String Independent Tracking: The 12kW model is equipped with dual MPPT channels, allowing separate connections to PV arrays with different orientations or tilt angles. This effectively resolves generation mismatch on multi-facing rooftops, delivering significantly higher overall yield than single-MPPT solutions.

02 Seamless Off-Grid / On-Grid Adaptation with ≤10ms Transfer

• The EVCity Hybrid Solar Inverter supports three operating modes — on-grid, off-grid, and adaptive. It operates in grid-tied mode when the grid is available and automatically switches to standalone off-grid power supply during grid failures, with a transfer time of ≤10ms, ensuring sensitive loads experience zero interruption.
• Core Value for Off-Grid Areas:
• In regions with weak grid infrastructure or no grid coverage at all, the EVCity Hybrid Solar Inverter can build a fully independent solar-storage microgrid:
• Standalone Operation: No reliance on utility power. PV panels generate electricity during the day, with surplus energy stored in LFP batteries (compatible with 280Ah / 314Ah cells). At night or on cloudy days, the battery provides continuous power — delivering 24/7 uninterrupted electricity.

• Black Start Capability: The ultra-fast 10ms adaptive switching (compared to the 20ms standard for 50Hz grid-tied systems) is well below the perception threshold of conventional equipment. For scenarios demanding the highest power quality — such as medical facilities, data centers, and precision manufacturing — this performance ensures critical equipment remains completely unaffected during grid disturbances, meeting the stringent requirements of premium residential and commercial projects.
• Intelligent Load Priority Scheduling: Supports flexible strategy configuration of "PV Priority → Battery Priority → Grid Priority," allowing customized dispatch logic tailored to end users' consumption patterns and local electricity tariff structures.

03 Flexible Scalability — Up to 9 Units in Parallel

• To accommodate projects of varying scales, the EVCity Hybrid Solar Inverter offers multiple expansion paths:
• Single-Phase Parallel Expansion: Up to 9 units of the 6.5kW single-phase inverter can be paralleled, flexibly matching power requirements from residential to small commercial applications.
• Three-Unit Three-Phase Configuration: Three single-phase inverters can be combined into a 380V three-phase system, supporting high-power loads and three-phase equipment — ideal for villas, factories, and commercial buildings.

• Flexible Energy Storage Scaling: The battery side supports multi-pack parallel connection, with configurations ranging from a single 16.64kWh pack to tens of kWh, covering the full spectrum from basic backup power to all-weather off-grid supply.

From high-precision MPPT tracking to 10ms seamless off-grid/on-grid switching and flexible multi-unit architecture, the EVCity Hybrid Solar Inverter puts "adaptability" at its core — providing overseas distributors, EPC contractors, and system integrators with a highly reliable, easy-to-deploy, and scalable solar-storage solution.

Whether for urban residential settings with stable grids or remote off-grid areas with limited infrastructure, it delivers truly uninterrupted power.
