Lithium storage,
2 kWh to 80 kW
One LFP product family for the whole shelf — portable stations, home batteries, hybrid inverters and commercial cabinets. Grade-A cells, a TDT smart BMS, and CAN/RS485 with Bluetooth and WiFi on every unit.

The range
Six families, one platform
Everything communicates over the same protocols and monitors through the same app — so a distributor stocks one system, not four.

RN-R series
Wall & rack LFP batteries, 25.6 V and 51.2 V. 5–16 kWh, 8 000 cycles at 95% DOD.
Battery specifications ↓
RN-V series
Solar hybrid inverters, 4–11 kW, on and off grid. Pure sine wave, MPPT, 220/230/240 VAC.
Inverter specifications ↓
RN-A / RN-L
Residential all-in-one — inverter and battery in one wall or stacked unit, 5 kW upward.
All-in-one systems ↓
RN-T / RN-Y
Stacked and cabinet systems for commercial and light-industrial sites, 16–80 kW.
All-in-one systems ↓

RN-A · RN-L · RN-T · RN-Y
All-in-one systems
Inverter and battery integrated into one unit — wall-mounted, stacked or cabinet — from residential backup to light-industrial installations. Full per-model datasheets are issued per enquiry.
RN-A
Residential all-in-one — inverter + battery in a single wall unit with MPPT solar charging and app control.
RN-L
Stacked residential system — modular battery stack for scalable home capacity.
RN-T
Stacked commercial cabinet — scaling into the 16–80 kW commercial range.
RN-Y
Cabinet system for commercial and light-industrial backup and peak-shaving duty.
Intelligence & safety
Smart by default
TDT smart BMS
Cell balancing, real-time monitoring and state-of-charge estimation, with protocol selection on the app, PC or touch screen.
Five-layer protection
Over-voltage, under-voltage, over-temperature, over-current and short-circuit protection built into every pack.
CAN / RS485 / RS232
Communicates with the inverters you already sell. Send us a protocol and we'll match it — no need to change your shelf.
Bluetooth & WiFi
Monitoring from iOS and Android apps and a PC dashboard, on every unit in the range.
Long cycle life
8 000 cycles at 95% DOD across the battery range, and 12 000 on the 32 kWh cabinet.
IP54, wide temperature
Rated IP54 with a −10 °C to 55 °C working window — LFP holds charge through heat that shortens lead-acid life.
