Store solar. Cut bills. Power reliably.
LEKTRI.PLUS is a compact, modular 48 V battery system you can scale from a single pack to a full bank — ideal for PV self-consumption, backup power, and smart energy management.
LEKTRI.PLUS
is a customizable energy storage kit composed of
LEKTRI.BOX
A vertical 48 V (16S) battery enclosure with integrated BMS, LCD, terminals, protections and wiring kit.
It’s designed for fast assembly, monitoring and expansion.
TERVOL L16 Cells
Premium LiFePO₄ prismatic cells installed inside the LEKTRI.BOX to achieve the desired capacity.
Use it to
- — Increase PV self-consumption and shift energy to evening/night.
- — Provide backup for critical loads.
- — Build modular storage for small businesses, telecom, cabins, or EV-charging support.
Key Benefits
Scalable from day 1
Start small and expand as needs grow (parallel up to 16 packs; stack up to 4 per base).
Safer chemistry
LiFePO₄ cells (EVE/CATL families) with long cycle life and stable operation.
built-in intelligence
Advanced BMS with cell balancing, temp/current protections, alarms and SoC LEDs.
real-time visibility
PC monitoring software for pack & cell voltages, temperatures, SoC, history logs.
inverter friendly
Pre-programmed CAN/RS485 protocols for leading inverter brands (Victron, GoodWe, Growatt, DEYE, Sofar, SMA, Solis, FoxESS, LuxPower, etc.).
LEKTRI.PLUS ecosystem
LEKTRI.BOX
(battery enclosure with BMS)
TERVOL L16 LiFePO₄ cells
(installed inside LEKTRI.BOX)
48 V / 16S vertical design; includes 48 V 16S BMS, LCD, terminals (P+/P-), busbars, latches, epoxy/EVA insulators, RS485-USB cable and accessories for a clean build.
Designed to fit EVE 280/280K/304 Ah and CATL 280/302 Ah prismatic cells (two 8-cell modules form a 16S pack).
Interfaces: CAN (to inverter), RS485 (pack-to-pack); DIP addressing for master/slave & pack IDs; RUN/ALARM/SOC LEDs.
BMS functions: over-charge/over-discharge/over-current/short-circuit protection, temperature protection, cell balancing.
Grade-A cells; tested cycle life targeting ≥ 6,000 cycles @ 0.5C, 100% DOD, 25 °C to ~80% remaining capacity (indicative).
Configurations
Per pack
48 V (≈ 51.2 V nominal), capacity based on cell selection (e.g., 280–304 Ah class).
Parallel expansion
Up to 16 packs for higher capacity/power; DIP switches set IDs and master/slave roles.
Physical stacking
Up to 4 packs stacked per base for compact footprint; inter-pack cabling provided.
Applications
Single-phase/three-phase hybrid or off-grid inverters; PV storage, peak shaving for small sites, backup.
Tip: combine LEKTRI.PLUS with LEKTRI.CO EV chargers and Energy Management for smart solar charging and load management.

Have questions?
We’ve got answers.
How many packs can I connect?
Up to 16 in parallel; set IDs via DIP switches (master/slaves).
Can I stack them physically?
Yes, up to 4 packs per base; connect inter-pack cables as shown in the manual.
Which inverters are supported?
Most leading hybrid/off-grid brands via CAN/RS485 profiles (see list above). Model-specific settings may apply.
Do I need a PC to monitor?
Optional but recommended—the LEKTRI-PLUS Battery Monitor provides real-time diagnostics and logs.
