Part 3: Detail Highlights – Designed for Simplicity

🏗️ All-in-One Integration – No Complex Setup

Unlike traditional systems that require separate inverters, batteries, and wiring boxes, the INV-12000 integrates everything into a single, sleek unit. No need to match components from different brands or worry about compatibility. Simply connect your solar panels and grid input, and you're ready to go. This plug-and-play design significantly reduces installation time and eliminates the hassle of complicated system configuration.

🔌 Intelligent Lithium Battery Activation

Say goodbye to complex startup procedures. The system supports automatic battery activation via PV input or mains power, allowing for effortless commissioning. Even if the battery is deeply discharged, the system can be revived without special tools or technical expertise – a feature that makes maintenance simple and stress-free.

⚡ Dual AC Outputs for Smart Load Management

The system features two independent AC output channels:

  • Universal socket outputs: 3KW + 3KW for flexible plug-and-play connection

  • Terminal block output: Full 12KW for hardwired connection

This design allows you to prioritize critical loads, separating essential appliances (refrigerators, lighting, medical devices) from non-essential ones (air conditioners, water heaters). In case of overload, only the less critical channel is affected, keeping your essentials running.

🛡️ Comprehensive BMS Protection – Safety First

The built-in Battery Management System (BMS) continuously monitors voltage, current, and temperature at the cell level, providing multi-layer protection:



Protection Type Threshold
Over-charge Protection Cell voltage ≥ 3.65V ± 0.05 (0.5s delay)
Over-discharge Protection Cell voltage ≤ 2.7V ± 0.05 (0.5s delay)
Over-current Protection ≥ 1.1% of rated current
Short-circuit Protection Instant cut-off
Over-temperature Protection Active monitoring

The BMS ensures the battery operates within safe parameters at all times, significantly extending service life and preventing hazardous conditions.

🔧 Minimal Maintenance – Built to Last

  • No regular maintenance required – LiFePO₄ chemistry is inherently stable and maintenance-free

  • Durable metal housing – protects internal components from physical damage

  • Rigorous quality testing – each unit undergoes strict safety testing including short-circuit, over-charge, and thermal shock tests

  • Long storage life – simply recharge every 3 months during long-term storage (recommended SOC: 40%~60%)


Part 4: Application Scenarios

🏠 Residential Home Energy Storage

Pair with rooftop solar panels to store excess daytime energy for use during peak tariff hours or at night. With 32KWH of storage, you can power your home through the evening and early morning, significantly reducing electricity bills and increasing energy independence. Powers all household appliances including air conditioners, refrigerators, TVs, lighting, and washing machines.

🔦 Emergency Backup Power (EPS/UPS)

With an ultra-fast switching time of 10–20ms, the system seamlessly transitions to battery power during grid outages. Keep your home office, medical devices, security systems, and essential appliances running without interruption – ideal for areas with frequent blackouts or unstable grid conditions.

☀️ Off-Grid & Remote Living

Perfect for cabins, farms, or remote locations without reliable grid access. When combined with sufficient PV panels (up to 15KW input), this system provides reliable 24/7 power for daily living, water pumps, and communication equipment. With 32KWH of storage, you can go days without sunshine and still have power.

🏢 Small Commercial & Light Industrial Use

Power small businesses, retail stores, restaurants, or workshops with reliable, clean energy. The 12KW continuous output handles moderate commercial loads while reducing operational energy costs.

🌍 Regions with Unstable Grids

Specifically designed for markets where power outages are common – the wide AC input voltage range (90–280V for appliances, 170–280V for computers) and auto-sensing 50/60Hz frequency make it adaptable to various global grid conditions.

🔋 Solar Self-Consumption Maximization

If you already have solar panels but want to store excess energy instead of wasting it, this system is your perfect partner. The dual MPPT trackers with 120–450VDC range work with most panel configurations, ensuring you capture as much solar energy as possible.
