The Tyon+F4 wall‑mounted LFP battery includes 25.6 V and 48 V voltage series, with 100 Ah / 200 Ah capacities corresponding to 2.56 kWh‑9.6 kWh energy ratings. Its wall‑mounted modular design greatly saves installation space. Auto‑addressing is supported without DIP‑switch configuration. An LCD display provides real‑time battery‑status readout. Built‑in universal communication protocols allow direct connection to PV inverters and UPS equipment. Custom CAN / RS485 interfaces are available on request. Eco‑friendly LFP cells achieve more than 5000 cycles at standard 0.5C charge‑discharge rate (1C maximum rate available as custom option). Multiple safety safeguards cover over‑charge, over‑discharge, over‑temperature and short‑circuit faults. It operates reliably across ‑30℃‑60℃ with IP20 protection and natural‑air / smart‑fan cooling. Easy‑to‑operate and maintain, it serves as supporting storage for residential PV‑storage applications.
