# AEMS100 fast commissioning: from power-up checks to the nine configuration items The VGRID POWER AEMS100 quick-commissioning guide starts with wiring: verify the 5 V supply of AEMS100 and SP30HBG2, PCS communications, battery-cluster communications and the WiFi/4G module before touching parameters. A missing link makes later configuration pages unreadable. Once the screen returns to the home page, configure the project items one by one and read back the key variables. The VGRID POWER AEMS100 quick-commissioning guide starts with wiring: verify the 5 V supply of AEMS100 and SP30HBG2, PCS communications, battery-cluster communications and the WiFi/4G module before touching parameters. A missing link makes later configuration pages unreadable. Once the screen returns to the home page, configure the project items one by one and read back the key variables. Step one: power and communications Confirm the 5 V supply to AEMS100 and SP30HBG2, and check that PCS communication, battery-cluster communication and the WiFi or 4G module are terminated as drawn. Once SP30HBG2 is powered from DC, grid or PV, the AEMS screen lights and returns to the home page. If the home page shows no data, inspect the RS485/CAN pinout and paralleling network cable before changing parameters. Step two: the nine configuration items The guide lists: (1) battery communication and protocol; (2) PCS communication, including unit count and model; (3) system operating mode; (4) battery charge/discharge inhibit SOC policy; (5) air conditioner if fitted; (6) fans if fitted; (7) genset IO and smart-load DO outputs; (8) other inputs and fire-alarm input; (9) the communication stick, covered in its own chapter. The interface distinguishes self-consumption (red path) from peak shaving (orange path), and the home page shows the active mode, which makes a photo record easy at handover. Step three: read-back and handover evidence After each item, return to the home page and check that battery data is readable, every PCS variable is present and the operating mode matches the contract. The guide advises checking the RS485 line and paralleling network cable if PCS variables are missing. Genset start and stop thresholds sit in the battery SOC management page and should be recorded together with the diesel strategy. Include configuration screenshots, firmware version, point-table revision and communication-stick ID in the commissioning report to prevent version drift during remote O&M. Frequently asked questions The screen is on but battery data is missing - where to start? Check the selected battery protocol and the CAN/RS485 wiring first, then compare SOC with the BMS backend. The AEMS100 current sign convention differs from many BMS definitions and is a frequent source of false alarms. Must the communication stick be configured on site? The guide lists it as item 9 and points to a dedicated chapter. Projects using remote monitoring, cloud diagnostics or OTA should have it configured and its ID registered during factory test or commissioning.
