Adopting mature large cylindrical LiFePO4 winding production technology, all units use 100% brand-new Grade A original cells without disassembled, second-hand or refurbished materials. The cells feature fewer burrs, low dust generation and zero C-angle stress damage. Equipped with low-pressure & highly sensitive safety valves to realize exhaust, decompression and explosion-proof protection, eliminating risks of cell swelling and liquid leakage. Each cell comes with a traceable QR code to guarantee consistent charging & discharging performance and top-tier safety for home storage.

Equipped with a high-end balanced smart BMS mainboard to monitor single cell voltage, temperature and real-time current. It provides six core safety protections: overcharge, overdischarge, overcurrent, short circuit, high temperature and low temperature protection. Supporting CAN & RS485 dual communication ports, the battery enables remote data monitoring via inverters and balanced parallel connection of multiple battery packs for long-term stable energy storage operation.

The stable chemical structure of lithium iron phosphate supports repeated charge-discharge cycles, outperforming NMC lithium batteries significantly in cycle lifespan. Rated for 6000 deep cycles, it perfectly fits daily frequent cycling for home solar storage, drastically reducing battery replacement frequency and lowering total investment of residential energy storage projects. CTS offers a 10-year official warranty for the whole unit.

Slim vertical wall-mounted powerwall form factor saves valuable indoor space. Adopting a detachable screw assembly scheme without welding, the unit can be disassembled and inspected without specialized tools, with on-site after-sales maintenance available. Two standard energy options: 5.12kWh (100Ah) and 10.24kWh (200Ah), multiple units can be connected in parallel to expand total storage capacity freely.

Fully compatible with mainstream inverter brands worldwide: Goodwe, Growatt, Deye, Solis, Sofar, Victron, Luxpower, Sungrow and more. It can be matched with solar panels, EV charging piles, household distribution boxes and UPS power supplies. Applicable to grid-tied storage, off-grid power generation, emergency backup and EV supplementary charging with outstanding universal adaptability.

Ultra-high energy conversion efficiency minimizes power loss during daytime solar charging and nighttime power discharge. It perfectly aligns with overseas peak-valley electricity tariff policies to slash household grid bills, and switches to backup power instantly when blackouts occur to sustain all home appliances.

Fully certified with CE, IEC, ISO9001, UN38.3, MSDS and RoHS, complying fully with sea and air transportation standards for lithium batteries. Complete official test reports are provided to ensure hassle-free customs clearance for all global destinations.
