This 48V 200Ah LiFePO4 powerwall communicates natively with 99% of major hybrid inverter brands via CAN and RS485 protocols. No firmware workarounds or third-party adapters are required.
Inverter Brand Compatibility: Supports Deye, Growatt, SolaX Power, Victron Energy, SMA, GoodWe, LuxPowerTek, SOFAR, Sungrow, Schneider Electric, and 14+ additional brands out of the box.
Native BMS-Inverter Handshake: CAN and RS485 enable bidirectional communication — the inverter reads state of charge, health, and protection status in real time.
Scalable Parallel Architecture: Stack up to 15 units in parallel, expanding total capacity from 10kWh to 72kWh without changing the inverter configuration.
Independent Module BMS: Each unit carries its own BMS. Adding a module does not require reconfiguring the existing stack.
Flexible Mounting: Wall-mount and vertical stacking are both supported with the same hardware, adapting to available installation space.
The 48V 200Ah LiFePO4 powerwall delivers 6,000+ charge cycles at 80% DoD — twice the 3,000-cycle threshold of alternative battery chemistries. At one full cycle per day, that maps to 16+ years of calendar operation, matched by a 10-year global warranty.
Usable discharge depth reaches 95%, meaning each 10kWh module contributes close to its full rated capacity — not the 50–60% typical of lead-acid systems.
The unit operates across -20°C to +50°C. An integrated automatic heating function activates below zero, maintaining electrochemical performance in cold climates. Above 50°C, charging and discharging continue normally. Flame retardant enclosure materials handle the thermal load without degrading cell performance or structural integrity.
Q1: What products do you offer?
Our main products is Lithium Ion Batteries. Now we can offer Home Energy Storage, Telecom Battery， Battery Pack，Lithium Battery 24V 48V etc.
Q2: How can I get a sample to check your quality?
If you need sample to test, please pay for the freight and sample cost. And the sample cost will be returned back to you after you place an bulk order more than our MOQ.
Q3: Can I have the products with my own logo?
Yes. We can offer both OEM and ODM service with prototype design and small MOQ.
Q4: How long can I expect to get the sample?
The samples will be ready for delivery in 3~5days after we receive the payment.
Production Process
The 48V 200Ah LiFePO4 powerwall connects via dual-mode WiFi and Bluetooth, giving installers and end-users complete system visibility without additional hardware.
Mobile App Monitoring: View state of charge, battery health, and usage patterns from any location — no on-site visit required for routine status checks.
Real-Time Alerts: The app pushes fault notifications the moment the BMS detects an abnormality, enabling same-day response before a failure escalates.
On-Site LCD Display: The unit’s built-in LCD shows live status data — useful during commissioning and routine inspections without a phone.
Remote Diagnosis: Technicians diagnose issues remotely via the app, reducing truck-roll frequency and lowering warranty claim costs for distributors.
Sleep and Wake Modes: Multiple sleep and wake-up modes minimize standby power draw when the system is idle.
The 48V 200Ah LiFePO4 powerwall serves as the battery layer across residential, mobile, and light-commercial energy systems — anywhere a 48V DC bus pairs with a hybrid or off-grid inverter.
In residential solar installations, the 700 × 580 × 210mm wall-mounted form factor fits utility rooms and garages without a dedicated equipment space. Parallel stacking to 72kWh covers larger homes or multi-day backup requirements.
For distributors supplying RV dealers, communication tower operators, or UPS integrators, the same unit covers all three channels. IP54 protection handles outdoor and semi-exposed environments, and CE plus UN38.3 certification clears EU import and air/sea transport simultaneously.
Solar street lighting projects and wind storage applications benefit from the -20°C cold-start heating function and the 95% discharge depth — both reduce oversizing requirements and lower the system bill of materials.
Terli manufactures the 48V LiFePO4 powerwall directly — no trading company in the supply chain. OEM and ODM orders receive custom capacity, enclosure design, and brand identity fully applied before shipment.
Sample units ship within 48 hours of order confirmation. The in-house R&D center handles capacity modifications and protocol adjustments without outsourcing to a third party. Factory design support for OEM enclosures is provided at no additional charge.
Standard model orders carry no minimum order quantity. Custom configurations carry a negotiable MOQ depending on capacity and certification requirements. Partners sign an NDA before receiving technical documentation or engaging the R&D team — protecting both parties before any IP is exchanged.
With 18+ years of battery manufacturing experience, the factory controls cell sourcing through final QC. Every OEM unit leaves with the same grade A cells and BMS hardware as the standard product.
Stocking a 48V LiFePO4 powerwall from a supplier without overseas warehouse inventory means 30–40 day delays that erode installer confidence. Terli maintains EU warehouses in Germany, Poland, and Romania — standard model orders ship within 3–7 days to EU addresses.
EU Delivery: 3–7 days from Germany, Poland, or Romania warehouse stock
US and AU Delivery: Tax-inclusive door-to-door service; no customs clearance required from the buyer
China Factory Orders: 30-day lead time for non-stock or custom configurations
Warranty: 10-year global warranty; extended warranty service available on request
Technical Support: 24/7 online support; overseas service branches handle on-site repair and replacement in EU and US markets
Payment Terms: T/T, PayPal, Western Union accepted
Shipping Carriers: UPS, FedEx, Post Mail, or buyer’s own freight agent
Distributor Channel Protection: Market-specific pricing tiers protect existing distributor margins from cross-territory undercutting
Certifications
Distributing the 48V 200Ah LiFePO4 powerwall across EU, US, AU, and Asian markets requires no additional certification filing — the unit ships with full multi-market coverage already in place.
EU Market Entry: CE, TUV, IEC62619, EN62619, IEC62040
Transport Compliance: UN38.3 — clears air and sea shipment requirements for all major freight routes
