The Terli 48V 5kWh Powerwall communicates natively with the inverter brands that installers already deploy — no custom firmware, no integration fees, no project delays.
Confirmed Compatible Inverters
DEYE, Luxpower, Goodwe, Growatt, SMA, Solis, Voltronic, and more — all validated through CAN and RS485 communication protocols. RS232 and SMBus are available for less common integrations.
Scale Without Changing the Inverter
Connect 2 to 14 Helios modules in parallel. A single Helios 5 delivers 5.1kWh; 14 units in parallel reach 71.4kWh — all managed by the same inverter. No rewiring the inverter side when a customer wants to expand storage.
Off-Grid and Hybrid Configurations
The 15S cell configuration matches off-grid inverter voltage windows; the 16S configuration targets hybrid inverter charge profiles. One product covers both installation types.
Indoor Wall-Mount Installation
The IP54-rated enclosure suits indoor plant rooms and utility spaces. The Helios 5 footprint (700 × 580 × 210 mm, 56 kg) fits standard wall-mount brackets with an LCD display for on-site state-of-charge monitoring — no separate monitoring hardware required.
Minimal Standby Loss
Self-discharge below 3% per month keeps backup-only installations charged between use cycles without requiring a dedicated maintenance charge schedule.
Every Terli LiFePO4 solar storage battery ships with three independent safety layers — chemistry, BMS, and hardware breaker — so a single component failure cannot cascade into a site incident.
BMS Full Protection Suite
Overcharge protection — disconnects at charge cutoff before cell stress occurs
Over-discharge protection — holds discharge cutoff at 40V to preserve cell health
Over-current and short-circuit protection — triggers within milliseconds under fault conditions
Thermal protection — monitors cell temperature and cuts power before runaway conditions develop
High-voltage protection — additional relay layer for higher-reliability residential deployments
LiFePO4 Chemistry Safety Advantage
Phosphate-based cathode chemistry eliminates the thermal runaway risk inherent in NMC and NCA cells. No cobalt in the cell structure removes the risk of exothermic decomposition under abuse conditions.
Abuse Test Results
Passed short-circuit, drop, nail penetration, impact, crush, thermal shock, overcharge, and over-discharge tests — no fire, no explosion across all test conditions.
Production-Level Quality Control
Each unit passes 37 production processes and 7 QC inspection steps, including end-of-line (EOL) detection, open-circuit voltage (OCV) detection, and full compatibility testing before packaging. Internal resistance held to ≤30mΩ minimizes heat generation under sustained discharge loads.
Maintenance-Free Operation
No memory effect, no electrolyte refill, no scheduled equalization charges required.
The Terli home battery storage system carries the certification stack that distributors and installers need to clear customs, pass retailer qualification, and satisfy utility interconnection requirements.

CE — Mandatory for EU market entry; confirms electromagnetic compatibility and electrical safety compliance
EN62619 — European safety standard specifically for stationary lithium energy storage systems
IEC62040 — International standard for uninterruptible power supply systems
CEC Accredited — Clean Energy Council accreditation required for Australian government solar incentive program eligibility
UN38.3 — Passed lithium battery transport testing; enables air, sea, and rail shipment without restrictions
MSDS — Material Safety Data Sheet for customs clearance, warehouse storage, and carrier documentation
