Outdoor boards for the grid, the charger and the battery.
Wide-temp, wide-voltage boards that acquire Modbus, CAN and RS-485 data for EV chargers, storage systems and PV inverters — built to sit outside, years at a time.
Application scenarios
Energy equipment lives outdoors and talks fieldbus — the board is the gateway between the asset and the cloud.
EV charging stations
Controller core that reads meters, drives the charge process and relays OCPP to the network. Wide-voltage 9-36V plus RS-485/Modbus connects to the energy meter and BMS.
PV inverters & energy storage
Comms and data-logging for inverter and battery management. CAN and RS-485 channels capture cell and string data for trend and anomaly analysis at the edge.
Field data acquisition
Outdoor RTU-style acquisition across Modbus/CAN/RS-485 with 8-bit GPIO for digital I/O. M.2 B-Key + SIM keeps a 4G/5G uplink for remote sites with no LAN.
Pain points & how we solve them
Weather, isolation and protocol soup — the three things that break outdoor electronics.
Outdoor heat, cold and humidity
Chargers sit in full sun and freezing winters. Boards are rated −20~+60℃ operating and −40~+85℃ storage, so the controller survives the seasons instead of being replaced each year.
Fieldbus and protocol soup
Meters, BMS and inverters speak different buses. We put RS-232/422/485, 2×CAN and 8-bit GPIO on one board, so you read every asset without a rack of protocol converters.
Unstable supply at the site
Grid and battery voltage varies. DC 9-36V wide-voltage input tolerates sag and surge, and runs straight from a 24V battery bus without an extra DC-DC converter.
Isolation & reliability review
Energy hardware needs credentials. We supply boards carrying CE/FCC/RoHS and ISO 9001, along with IPC-A-610 assembly and full aging test, so your grid approval pass is smoother.
