Deye LS4G 4G Stick Logger for Inverters
The LS4G is Deye's 4G/LTE stick logger: it brings an inverter online even where neither Wi-Fi nor a network cable is available. It plugs into the inverter communication port, takes its power from it with no external supply and uploads data to the SOLARMAN Smart / Deye Cloud platform drawing just 1W.
It is the usual answer for remote roofs, farm buildings, irrigation pumps, mountain huts and construction sites, where fixed connectivity does not exist or is unstable. Three LEDs separately show the link to the mobile network, to the inverter and to the server, making diagnosis immediate. It is the cellular alternative to the wired LSE-4W logger and integrates with Deye energy meters and smart accessories.
