This wall‑mount battery delivers a unique combination of aesthetic design, robust performance, and operational intelligence that sets it apart in the residential storage market.

1. Slim, Space‑Saving Wall‑Mount Design
With dimensions of just 600×410×166mm, the YF51100LFP‑WM hangs flush on your wall like a piece of modern art. It frees up valuable floor space in garages, utility rooms, or even living areas, making residential storage installations cleaner and more professional.

2. Proven LiFePO4 Safety & 6,000‑Cycle Longevity
Built on intrinsically stable Lithium Iron Phosphate chemistry, this battery offers superior thermal and chemical safety. Rated for 6,000 cycles at 80% depth of discharge (25°C, 0.5C), it delivers reliable daily performance for well over a decade – an outstanding ROI for homeowners and a low‑warranty product for you.

3. Integrated Smart BMS with Active Balancing
The advanced Battery Management System provides full protection against overcharge, over‑discharge, over‑current, short circuit, and temperature extremes. Active cell balancing ensures that every cell works at peak efficiency, maximizing usable capacity and extending service life.

4. Crystal‑Clear LCD & LED Status Indicators
Unlike many batteries that rely solely on app monitoring, the YF51100LFP‑WM features an built‑in LCD display showing real‑time voltage, state of charge (SOC), current, and temperature – plus LED indicators for at‑a‑glance status. This transparency builds end‑user confidence and reduces support calls.

5. Universal Inverter Compatibility
Equipped with CAN, RS485, and RS232 communication ports, this battery speaks the language of virtually every major hybrid and off‑grid inverter (Victron, Growatt, Deye, Sungrow, Solis, Sofar, etc.). Plug‑and‑play integration means fewer compatibility headaches.

6. High Power, Scalable Architecture

• 100A max charge/discharge current handles high‑power solar arrays and home loads.

• Up to 15 units in parallel (tested) allows scaling from 5.12kWh to over 75kWh – ideal for growing families or commercial applications.

• Built‑in parallel circulation control module ensures balanced operation without external hardware.

7. Rugged, Weather‑Resistant Enclosure (IP55)
Rated IP55 for dust and water jet resistance, the battery can be installed in garages, covered patios, or semi‑protected outdoor areas, giving you and your customers more placement flexibility.

8. Globally Certified for Market Readiness
Fully certified with UN38.3, CE, IEC62619 (pack) and IEC62619/UL1642 (cells), the YF51100LFP‑WM meets the highest international standards for safety and transport, simplifying your market entry.

Q1: What makes the YF51100LFP-WM different from other wall‑mount batteries?
A: The YF51100LFP‑WM combines three critical advantages: (1) Built‑in LCD display for instant local status – no app needed; (2) Ultra‑thin 166mm depth for tighter wall mounting; (3) Proven compatibility with all major inverter brands via CAN/RS485/RS232. It’s designed as a true drop‑in for residential systems, not just a battery in a box.

Q2: Is this battery certified for international shipping and sale?
A: Yes. The battery pack carries UN38.3, CE, and IEC62619 certificates. Cells are certified to IEC62619 and UL1642. We supply all needed documentation for air/sea freight and customs clearance in most major markets. Additional certifications (UL, VDE, UKCA) can be arranged for volume orders.

Q3: What is the minimum order quantity (MOQ) for OEM/ODM custom branding?
A: For full custom branding (logo, color, packaging, manual), typical MOQ is 50-100 units. For pilot projects or non‑customized wholesale, we can accept smaller quantities. Contact our sales team to discuss your specific needs.

Q4: Can I get samples for testing and certification before placing a bulk order?
A: Absolutely. We provide evaluation samples with standard branding within 7-15 days. Samples allow you to test compatibility, performance, and install the unit in real‑world conditions. Sample cost is often credited toward your first bulk order.

Q5: What is the lead time for wholesale orders?
A: Standard lead time for non‑customized orders is 15-25 days after payment confirmation. Custom branded orders typically require 20-30 days, depending on artwork approval and packaging preparation. Faster turnaround can be arranged for urgent projects.

Q6: Do you offer technical support for inverter integration?
A: Yes. Our engineering team provides detailed communication protocol documents and can assist with initial setup, troubleshooting, and integration with specific inverter models. We also maintain a growing compatible inverter list that we share with all wholesale partners.

Q7: What warranty do you provide for wholesale customers?
A: We offer a standard 5-year warranty on the YF51100LFP‑WM, covering manufacturing defects and BMS failures. Extended warranty options (7 or 10 years) are available for qualified partners. Our warranty terms are designed to protect your brand and reduce service risk.

Q8: How does the self‑discharge and storage recommendation work for this battery?
A: The battery has very low self‑discharge (<3% per month). For long‑term storage (over 3 months), we recommend storing at 40%-60% SOC in a clean, dry environment between 0°C and 40°C. We provide detailed storage guidelines with every shipment.

Q9: Can I use this battery with an existing solar system that already has a different battery brand?
A: For optimal performance and BMS communication, we recommend using YF51100LFP‑WM batteries as a dedicated bank. However, if you wish to mix with other batteries, you must use an open‑loop (voltage‑based) control and ensure proper system design. We advise consulting with our technical team before mixing chemistries or brands.

Q10: How do I place an order or request a custom quote?
A: Simply contact our sales team via email or the form on our website. Provide your target quantity, desired specifications, branding requirements, and shipping destination. We will respond with a detailed quotation, lead time, and next steps for sample or mass production.
