Overview
INVT Battery is a professional-grade energy storage product line developed by INVT, a leading Chinese manufacturer of industrial power solutions. Designed for commercial and industrial applications, these batteries are engineered to deliver consistent performance in demanding environments such as data centers, telecommunications, and solar power systems. Available in both lead-acid and lithium-ion chemistries, INVT batteries comply with international safety standards including UL and CE certifications. The product range includes modular designs that allow for scalable capacity configurations to meet diverse energy storage needs.
Structure and Working Principle
Lead-acid variants utilize absorbent glass mat (AGM) technology for spill-proof operation, with lead dioxide positive plates and porous lead negative plates immersed in sulfuric acid electrolyte. Lithium-ion models employ LiFePO4 cathode chemistry for enhanced thermal stability and cycle life. All INVT batteries incorporate advanced charge controllers to prevent overvoltage during charging. The built-in Battery Management System (BMS) in lithium models monitors cell balancing, temperature, and state-of-charge to optimize performance and safety.
Key Features
1. **Deep Cycle Capability**: Withstands 80% depth of discharge (lead-acid) or 90% (lithium) without significant capacity degradation. 2. **Temperature Resilience**: Operational range of -20°C to 60°C for select lithium models. 3. **Maintenance-Free Design**: Sealed construction eliminates electrolyte refilling requirements. Notably, the lithium series offers 3,000+ charge cycles at 80% capacity retention, making them suitable for high-frequency cycling applications like peak shaving in smart grids.
Application Areas
**Critical Infrastructure**: Primary backup for hospital emergency systems and air traffic control towers. **Renewable Energy**: Energy buffer for solar/wind farms, with compatibility for 48V to 800V DC systems. Industrial users value these batteries for their rapid recharge capability (lithium models reach 80% charge in 1 hour) and vibration resistance, making them ideal for mobile applications like railway signaling and marine power.
Maintenance and Precautions
Quarterly voltage checks are recommended for lead-acid batteries stored in float service. Lithium batteries require annual capacity verification through full discharge/charge cycles. Always use manufacturer-approved chargers to prevent thermal runaway in lithium variants. For lead-acid batteries, maintain ambient temperature below 40°C to avoid accelerated water loss in vented models. Terminal cleaning with anti-corrosion gel extends service life.
B2B Procurement Guide
1. **Capacity Planning**: Calculate required ampere-hours based on load profiles; add 20% buffer for lead-acid designs. 2. **Certification Check**: Verify IEC 60896-21/22 compliance for stationary applications. Bulk purchasers (>100 units) can negotiate 8–12% discounts through INVT's industrial partner program. Consider total cost of ownership – while lithium batteries have higher upfront costs, their longer lifespan often results in lower per-cycle expenses versus lead-acid alternatives.
