48V Solar Battery Compatible with 30+ Inverter Brands

Terli’s Deep Cycle High Capacity 48V Lithium Battery communicates natively with over 30 hybrid inverter brands via RS485, RS232, and CAN — no custom firmware or proprietary adapters required. System integrators deploying mixed-brand projects confirm compatibility before shipment, eliminating on-site rework.

Verified compatible inverter brands:

This deep cycle battery supports both on-grid hybrid and off-grid inverter topologies. The LiFePO4 48V unit registers automatically on supported inverters — SOC, voltage, temperature, and charge state stream directly to the inverter display without manual parameter entry.

Grade A LiFePO4 Cells and Intelligent BMS Built for Long-Term Projects

Every unit in Terli’s deep cycle lithium battery line uses Grade A LiFePO4 cells — new, not refurbished or rebranded. Each cell passes individual voltage and internal resistance testing before assembly. The result is a guaranteed ≥8,000-cycle lifespan that competitors using unbranded cells cannot match.

Manufacturing and cell integrity:

• Fully automatic laser welding: Eliminates the flying-wire connections common in lower-cost units that loosen over time and degrade internal resistance.

• Industry-leading PCB sampling board: Safer signal paths, more efficient charge distribution, and reduced failure points versus conventional PCB designs.

• Three-proof paint on all sampling points: Prevents oxidation and internal resistance creep caused by humidity and corrosive environments.

• Modular cell design: A faulty module swaps out independently — the full unit does not require replacement.

• 100% pre-shipment testing: Voltage and internal resistance matched per unit before leaving the factory.

Built-in intelligent BMS:

• 5 major protection functions: Overcurrent, overvoltage, over-temperature, short circuit, and deep discharge protection active at all times.

• Cell-level balancing: The BMS maintains balance across all 16 cells in series, preventing capacity drift over extended cycle life.

• Independent BMS per module: Each module operates with its own BMS — a single module fault does not disable the system.

Real-Time Monitoring for the Terli 48V Lithium Battery — Local, Wireless, and Cloud

Installers and end-users can observe battery status through four independent channels without visiting the installation site. The built-in LCD displays SOC, voltage, current, and temperature directly on the unit. Optional WiFi uploads live data to a cloud server, accessible from any browser or the mobile app.

Monitoring channels:

• Built-in LCD display: Shows real-time battery status at the unit — no secondary device required. Eliminates the guesswork of indicator-light-only systems.

• Bluetooth (optional): Wireless status check within 5 meters — useful during commissioning and on-site diagnostics.

• WiFi cloud monitoring (optional): Streams data to a remote server; monitor and configure via computer or smartphone from any location.

• Windows upper system software: Full parameter setting and monitoring on desktop for fleet-level management across multiple units.

Remote capabilities:

• App-based diagnostics: view fault codes, charge history, and real-time readings without a site visit.

• Remote parameter setting: adjust charge thresholds and protection limits through the app or Windows software.

• Inverter data exchange: RS485, RS232, and CAN pass BMS data directly to the inverter — SOC and fault states visible on the inverter display without separate wiring.

Modular 48V Battery Design Built for Fast Deployment and Flexible Expansion

Terli’s deep cycle high capacity 48V lithium battery uses a floor-mounted chassis with 4 universal wheels — one person repositions the unit without mechanical equipment or a second technician. The top-facing interface keeps all cable runs vertical and untangled, unlike side-interface designs that create crossed wiring when units are stacked.

Physical design advantages:

• 4-wheel floor mount: Moves freely on any flat surface during installation or site reconfiguration — no lifting required.

• Top-facing interface layout: All power and communication connections exit from the top, eliminating cable crossover in multi-unit rows.

• Standard quick-stacking pulling ear: Aligns and locks adjacent units during parallel configuration without custom brackets.

• Compact footprint: 700 × 580 × 210 mm fits standard residential enclosures and commercial battery rooms.

Scalability:

Connect up to 15 units in parallel for a maximum 200A discharge rate and up to ~225 kWh of total storage. Each additional unit added to the stack increases capacity linearly — no controller reconfiguration required.

Maintenance:

The modular internal structure lets a technician swap a single faulty cell module without removing or replacing the full enclosure. Semi-automatic production supports both vertical and horizontal module orientation, so enclosure layouts can adapt to site constraints.

Where the Deep Cycle High Capacity 48V Lithium Battery Performs

This deep cycle lithium battery serves nine distinct application categories — from single-family solar installations to industrial backup and mobile energy platforms.

Stationary energy storage:

• Residential solar storage: Pairs with any of 30+ compatible hybrid inverters for self-consumption and grid-backup in homes. IP54 protection allows installation in garages, sheds, or semi-exposed utility rooms.

• Commercial energy storage: Offices, small stores, and churches use the 15-unit parallel stack to cover loads from 15 kWh to ~225 kWh within a single system.

• Industrial backup power: Factory and facility backup systems benefit from 200A continuous discharge and 80–90% DOD to sustain heavy loads through outages.

• UPS systems: The 48V solar battery integrates into UPS topologies requiring high cycle frequency and stable voltage output over thousands of discharge events.

• Telecom and communication base stations: BMS communication via RS485/CAN delivers state-of-charge data directly to station management systems.

Renewable generation storage:

• Photovoltaic (PV) energy storage: Stores excess solar generation for evening and overnight discharge — compatible with Growatt, Deye, SMA, and other PV-optimized hybrid inverters.

• Wind power storage: Handles irregular charge cycles common in wind applications without accelerating cell degradation.

Mobile and off-grid:

• RV and camper energy: Floor-mounted with wheels for repositioning inside vehicle bays; LCD display gives occupants direct SOC visibility.

• Electric boat and marine: Sealed LiFePO4 chemistry eliminates off-gassing risk in enclosed marine compartments.

• Solar street lighting: Handles high daily cycle frequency in outdoor environments protected by IP54.
