The Terli 48V powerwall certifications span every compliance gate EU importers and Australian distributors require before approving a new residential storage SKU.
TUV: German/EU safety authority certification — EU distributors and solar installers require this TUV CE LiFePO4 battery approval before committing to a new powerwall product line.
CE: EU market entry compliance — mandatory for import and resale across all EU member states.
EN62619: European standard for secondary lithium cells — satisfies the compliance documentation EU distributors need for residential LiFePO4 storage products.
IEC62040: International standard for UPS and battery storage systems — covers grid backup and off-grid deployment scenarios.
UN38.3: International transport safety standard — qualifies air and sea freight without DG documentation gaps or carrier rejection at booking.
CEC Accreditation: Australian Clean Energy Council approved — this CEC accredited home battery listing qualifies for AU government STC rebate programs, removing the key eligibility barrier for AU distributors.
All six 48V powerwall certifications transfer to OEM-labeled product — no reapplication required for brand owners.
The Terli OEM Iron Li-ion 48V Lithium Battery Powerwall delivers smart home battery monitoring via WiFi/GPRS cloud connectivity. End-users gain full system visibility without on-site inspection.
WiFi/GPRS Cloud Platform
The intelligent cloud platform streams voltage, state of charge, and cycle data in real time. Distributors use this premium feature to differentiate and command higher retail prices.
One-Key APP Real-Time Monitoring
End-users check live status with a single app tap — fewer support calls and stronger brand loyalty for tech-forward residential buyers.
Independent BMS Per Module
Each Helios module runs its own BMS for cell-level LiFePO4 BMS protection. Overtemperature, overvoltage, and overcurrent cutoff each trigger at the source — not downstream.
Pack Level Energy Optimization
The stack-level controller distributes charge and discharge load evenly across all modules. This even balancing sustains 6000-cycle performance across the product’s design life.
Safe LiFePO4 Chemistry
LiFePO4 cells resist thermal runaway under fault conditions. That stability lets the BMS enforce multi-layer APP battery management — the foundation of warranty-grade reliability.
The Terli OEM Iron Li-ion 48V Lithium Battery Powerwall connects into any hybrid solar battery system via CAN/RS485 — no gateway adapters, no custom firmware.
CAN/RS485 native handshake: CAN and RS485 battery-inverter communication runs at the protocol level. Distributors eliminate inverter compatibility troubleshooting from every installation.
Single-phase and three-phase AC: The system covers both AC configurations, spanning the full residential installation range in EU and AU markets.
On-grid and off-grid operation: The powerwall switches between hybrid on-grid and off-grid modes, delivering uninterrupted power regardless of grid status.
Parallel scaling: Multiple units stack in parallel for any residential load — from a compact home system to a property needing expanded backup capacity.
Pull-ear quick stacking: The wall-mount bracket system aligns units without precision tools, completing a standard residential energy storage integration in under two hours.
Brand owners source the Terli OEM lithium battery powerwall with full logo, color, and label customization — no rebranding friction at the factory level.
The OEM/ODM program extends beyond cosmetic changes. Size and capacity adjustments accommodate specific residential SKUs, letting brand owners build a differentiated custom 48V battery pack without redesigning from the ground up.
Every OEM-labeled unit ships with the same compliance coverage as the factory product — TUV/CE and CEC accreditation transfer without reapplication. Brand owners enter EU and AU markets without commissioning a separate certification run.
Terli’s advanced production line delivers consistent cell-to-cell quality at scale. Brand owners get a product matching their warranty commitments from day one. Private label energy storage reaches the market faster than a build-from-scratch development cycle.
The Helios powerwall covers the four residential home energy storage scenarios distributors encounter most. The compact, wall-mounted form factor fits any home without structural modification.
Solar self-consumption: The solar self-consumption battery draws on 100% DoD, delivering the full stored capacity after sunset — no energy held in reserve.
Home backup power: The home backup power battery switches to stored energy the moment the grid drops, protecting appliances and critical loads through outages of any duration.
Peak-valley arbitrage: The system charges during low-tariff overnight hours and discharges during peak pricing windows, reducing the homeowner’s electricity bill on every billing cycle.
Off-grid living: The Helios stack runs fully independent of the grid. With 6000-cycle durability and a 10-year design life, distributors can offer it as a permanent off-grid solution.
The modular, compact design and light weight allow wall-mounting in garages, utility rooms, and tight residential spaces without structural reinforcement.
