Terli
The Terli AC 220V emergency power system delivers 220V / 50Hz output backed by a 48V LiFePO4 battery bank, available from 5kWh to 100kWh in a standard 19-inch rack-mount form factor.

| Cycle Life | > 6000 cycles |
| Design Life | 10 years |
| Operating Temperature | -10°C to 50°C |
| Self-Discharge Rate | < 3% per month |
| Parameter | Value |
|---|---|
| Form Factor | 19-inch rack-mount |
| Pack X / ESS Height | 5U |
| Telecom Battery Height | 6U |
| Size vs. Lead-Acid | ~½ size and weight |
| DC Output | Dual DC output ports |
| Communication | RS485 / CAN |

| BMS | Independent BMS per module |
All capacity models support RS485/CAN communication and modular parallel expansion.
The Terli residential battery backup system runs unattended through grid outages and daily solar cycles — the BMS and cell chemistry handle protection automatically, without manual intervention.
Independent BMS Per Module
Each rack module carries its own BMS. A fault in one module triggers protection on that unit only — the rest of the bank continues supplying power. No single failure takes down the full system.
Full BMS Protection Suite
Overcharge protection — disconnects before cell ceiling voltage is exceeded
Over-discharge protection — preserves cell health at low state of charge
Over-current and short-circuit protection — triggers within milliseconds under fault conditions
Built-in PCM layer — additional hardware protection independent of BMS firmware
LiFePO4 Chemistry Safety
Lithium iron phosphate cells contain no cobalt and no toxic materials. The phosphate cathode structure prevents thermal runaway — no fire, no explosion risk — making the system safe for indoor installation in garages, utility rooms, or living areas.
CE/UL Approved
Safety independently verified by CE and UL certification bodies — not a self-declaration.
Always-Ready Standby
Self-discharge below 3% per month means a fully charged bank retains >94% capacity after three months of standby — reliable when a grid outage happens without warning.
No Memory Effect
Charge the battery at any state of charge with no conditioning cycles required.
Lead-acid backup batteries cost less upfront but deliver a fraction of the lifetime value. This LiFePO4 home storage system makes the replacement case with data installers can use in every sales conversation.
| Factor | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | > 6000 cycles | ~1000 cycles |
| Longevity Advantage | 6–8× longer | Baseline |
| Size & Weight | ~½ equivalent | Baseline |
| Maintenance | None | Water refills, equalization, corrosion |
| Self-Discharge | < 3% per month | 5–15% per month |
| Memory Effect | None | Present |
| Toxic Materials | None | Lead + acid |
| Design Life | 10 years | 2–3 years |
Key talking points for installers:
One purchase replaces 3–4 lead-acid cycles — total cost of ownership favors LiFePO4 within the first replacement cycle
Half the installation footprint — fits in spaces where a lead-acid bank of equal capacity would not
Zero maintenance calls — no water refills, no equalization charges, no corrosion checks reduce post-sale service burden
Safe for indoor residential spaces — no acid fumes, no toxic gas, no spillage risk
Reliable standby — ❤️% monthly self-discharge keeps the bank ready without a maintenance charge schedule
The Terli AC 220V emergency power system carries the full certification stack that distributors need to clear customs, qualify for retailer listing, and satisfy residential safety regulations.
CE — Mandatory for EU market entry; independently verified electrical safety and electromagnetic compliance
TUV — Independent safety certification required by European commercial buyers and project finance lenders
UL — North American safety standard; CE/UL together cover major Western market channels
KC — Korea Certification for Korean market distribution and retail qualification
CB (IECEE CB Scheme) — International safety standard recognized in 50+ countries; simplifies multi-market product registration
UN38.3 — Passed lithium battery transport testing; enables air, sea, and rail shipment without shipping restriction
MSDS — Material Safety Data Sheet for customs clearance, warehouse storage, and carrier documentation
3C — China Compulsory Certification for domestic Chinese market sales
ISO — Quality management system certification covering all production operations
All certification documents are available on request for import compliance files, retailer qualification, and project bankability reviews.
OEM-produced units qualify under the same certification framework — contact us for brand transfer details.
The Terli solar battery system covers five residential and light-commercial use cases with a single certified platform — from essential outage backup to full off-grid independence.
Grid Outage Emergency Backup
220V AC output powers refrigerators, lights, routers, and medical devices the moment the grid fails. No manual switching required — the system transitions automatically.
Solar Self-Consumption
Store surplus daytime solar generation and discharge after sunset. A 10kWh bank covers standard evening household loads, reducing grid import to near zero on clear days.
Whole-Home Energy Independence
20–50kWh configurations power full residential loads including air conditioning and EV charging, with enough reserve for multi-day cloudy periods.
Off-Grid Remote Home
50–100kWh banks supply complete off-grid residences with no utility connection — clean, silent, zero-emission power from a compact rack-mount system.
Capacity Selection Guide
| Capacity | Best For |
|---|---|
| 5–7 kWh | Essential backup: lights, fridge, router |
| 10 kWh | Standard home: full evening load coverage |
| 20 kWh | High-consumption home + EV charging |
| 50–100 kWh | Off-grid or commercial backup |
The modular design allows capacity expansion by adding rack units — no system redesign when a homeowner’s energy needs grow.
Terli designs the AC 220V emergency power system for installers who need a reliable rack platform and for distributors who need a factory that supports private-label partnerships.
19-Inch Standard Rack Form Factor
Three product variants fit standard equipment racks without custom mounting hardware:
Pack X: 19-inch 5U — residential solar storage
Energy Storage System: 19-inch 5U — home and light-commercial ESS
Telecom Battery: 19-inch 6U — base station and machine room backup
Quick-Stack Installation
Each module features a pulling ear handle and standard rack-mount design. Units stack and secure in minutes — reducing installation labor cost per project versus custom-form battery systems.
Modular Capacity Expansion
Add rack modules to expand from 5kWh to 100kWh without replacing the inverter or rewiring the DC bus. One platform scales with every customer’s growing energy needs.
OEM/Private Label Available
Custom branding, logo, and labeling applied to any capacity configuration. CE/TUV/KC certification documentation transferable to OEM brands.
7-Step Production Process
Outer box preparation → cell preparation → product assembly → completed unit → product testing → product packing → shipment — each step with dedicated QC inspection under ISO-certified quality management.
Grade A LiFePO4 Cells
Safe lithium iron phosphate cells with no cobalt and no toxic materials across all capacity tiers.
