Key Features & Advantages

1. High Capacity with Usable Energy

Boasting a rated capacity of 16.07 kWh and a 90 % depth of discharge, the LVTOPSUN G4 allows users to utilize nearly all of the stored energy without compromising battery health. This deep discharge capability ensures more of the battery’s stored energy is available for everyday use and emergency power needs.

2. Long Cycle Life

With a cycle life of approximately 8,000 cycles at 90 % DoD, this battery delivers exceptional longevity. For most residential applications, this means many years — often over a decade — of reliable performance before capacity begins to notably diminish.

3. Intelligent Battery Management System (BMS)

The LVTOPSUN G4 is equipped with a sophisticated BMS that ensures optimal performance and safety. It continuously monitors voltage, current, temperature, and state of charge while protecting against overcharging, over-discharging, short circuits, and thermal stress. Integrated safety measures help protect both the battery and connected systems.

4. Robust and Durable Build

Rated IP65, this battery is sealed against dust and low-pressure water jets, making it suitable for indoor and sheltered outdoor installations. Its rugged design ensures stable operation across a wide range of climates and environmental conditions.

5. Compatibility & Easy Integration

Featuring multiple communication interfaces (RS232, RS485, CAN), the LVTOPSUN G4 integrates seamlessly with most hybrid and off-grid inverters on the market. This compatibility simplifies installation and improves system performance monitoring.

6. Expandability for Larger Systems

One of the key strengths of this battery is its scalability. Up to 63 units can be connected in parallel, enabling a total storage capacity that can exceed 1 MWh for larger residential estates, commercial properties, or off-grid systems.

7. Smart Monitoring & Control

With built-in display and optional connectivity options, users can easily view battery status, state of charge, and performance metrics in real time. This offers greater control over energy use and system performance optimization.

Ideal Applications

The LVTOPSUN G4 16 kWh battery is versatile and suitable for many energy storage scenarios, including:

• Residential solar systems requiring reliable day-to-day storage

• Backup power during grid outages

• Hybrid solar installations that optimize peak/off-peak usage

• **Small commercial sites and business continuity power solutions

• Off-grid systems in rural or remote areas
