5.12kWh LiFePO4 All-in-One Solar Battery With Inverter 51.2V 100Ah Wall-Mounted

Introducing the YF-48100PWI, a fully integrated all-in-one energy storage system that combines a high-performance LiFePO4 battery with a 5kW pure sine wave hybrid inverter. With 5.12kWh of usable energy (51.2V, 100Ah), this wall-mounted solution is engineered to simplify residential solar backup, off-grid living, and peak load shifting. Unlike separate components, the YF-48100PWI arrives pre-wired and pre-tested – dramatically reducing installation time and compatibility issues. Backed by Yunfan Factory’s 13+ years of battery R&D, 60+ in-house engineers, and ISO9001/ISO14000 certifications, this system is the perfect private-label opportunity for distributors, installers, and renewable energy brands looking to offer a reliable, scalable, and profitable energy storage product.

This all-in-one system delivers clear advantages that resonate with end-users while protecting your margins.

1. True Plug-and-Play Integration – Fewer Service Calls

• Battery + Inverter + BMS in one unit – no external communication wiring hassles.
• Pre-configured LiFePO4 profile with CAN/RS485 ensures compatibility with major inverters (or it works standalone).
• Parallel capability – up to 6 units in inverter mode, or 26+ units as common powerwall – perfect for scaling.

2. High-Power Performance for Real Homes

• 6000W PV input (450VDC max, MPPT range 120-430V) – handles large solar arrays.
• 100A max battery charge/discharge – enough for most home loads.
• 10ms transfer time (PC mode) – keeps sensitive electronics running during outages.

3. Safety & Longevity You Can Trust

• LiFePO4 chemistry – no thermal runaway, safer than NMC.
• 16S 100A BMS with full protection: overcharge, over-discharge, high/low temperature, short circuit.
• ≥6000 cycles @ 80% DoD – designed for 10+ years of daily use.

4. Smart Monitoring – Reduce Support Tickets

• WiFi or GPRS monitoring – users can check system status remotely.
• Clear LCD display & LED indicators – local status at a glance.

5. Flexible Installation & Compliance

• Wall-mounted, compact design (940*480*195mm, 73kg).
• CE, UN38.3, MSDS certified – ready for international shipping.
• Wide operating temperature: charge (-5°C to 60°C), discharge (-10°C to 65°C).

Q1: What is the MOQ for custom branding?
A: Typically 20-50 units for logo and packaging customization. For full firmware changes, consult our engineering team.

Q2: Can this system work with my customer’s existing solar panels?
A: Yes. The MPPT range (120-430VDC) and 450VDC max open voltage cover most residential solar strings.

Q3: What’s the difference between “inverter mode" and “common powerwall" parallel?
A: In inverter mode, up to 6 units can be paralleled for higher AC output (up to 30kW). As a common powerwall, over 26 units can be paralleled for capacity expansion only (one master inverter + additional battery-only units).

Q4: What certifications do you provide for importers?
A: We provide UN38.3, MSDS, CE for the complete system, plus cell-level IEC62619 and UL1642. We can assist with additional regional certifications (UKCA, VDE, etc.) for volume orders.

Q5: Do you offer samples for testing?
A: Yes. Sample orders are welcome with short lead time. We provide technical support during integration.

Q6: What is the warranty period?
A: 5 years standard, extendable for qualified partners. Battery designed for >6,000 cycles.

The YF-48100PWI all-in-one system is your shortcut to offering a competitive, reliable, and profitable solar battery product. With Yunfan Factory’s engineering depth, customization flexibility, and global logistics, you can launch your branded energy storage line with confidence.
