Facing the inverter it has two pairs of PCS terminals, P1 and P2, and a dedicated CAN port, JP6. A cluster breaker isolates the string, while two further breakers feed the box's DC\/DC and AC\/DC power supplies.\u003c\/p\u003e\n\u003cp\u003eIt also sends 24 V down the stack for the management unit and fans in each pack, carries CAN through the daisy-chained pack cables and assigns each pack its address. A green lamp shows the high-voltage bus is energised; a red one signals an alarm.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eMonitoring, data and remote access\u003c\/h3\u003e\n\u003cp\u003eA gateway built into the box saves a CSV record of BMS data every 5 seconds and holds no less than 365 days of history, exportable through its web interface. It reports to Solis's Ginlong Cloud, pushing alarms as they occur and cluster and cell data once a minute by default.\u003c\/p\u003e\n\u003cp\u003eFor its uplink the gateway can use a wired network, Wi-Fi in station mode, or 4G, and the 4G route accepts a 15 × 12 mm Micro SIM only. Out of the box its Wi-Fi runs as an access point, so the commissioning engineer can open the local web pages from a phone. Gateway and BMS firmware can be upgraded remotely.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eOne box per cluster, and running clusters in parallel\u003c\/h3\u003e\n\u003cp\u003eThe box count always equals the cluster count. With several clusters, the boxes are daisy-chained on the DC side, P2 of one to P1 of the next, while the first box's P1 and the last box's P2 go to the inverter's BAT1 and BAT2 inputs. Each box's JP4 port links to the next for parallel CAN and cluster addressing.\u003c\/p\u003e\n\u003cp\u003eStart-up follows the same chain. The box holding the inverter communication powers up first, the rest follow in communication order, and the cluster quantity is entered in the inverter app before the cluster breakers close.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eSiting and wiring the box\u003c\/h3\u003e\n\u003cp\u003eSitting at the top of a column, the box shares the cluster's conditions: indoors, IP20, in a fireproof room with its own fire alarm and extinguishing equipment. Its manual switch goes to off before any pack is installed.\u003c\/p\u003e\n\u003cp\u003eThe DC leads to the inverter are made up on site, 25 mm² for clusters of 3–9 packs and 35 mm² for 10–13. For the inverter CAN link Solis recommends 0.35 mm² cable, no longer than 18 m. With the S6-EH3P125K10-NV-YD-H inverter, one phase of its backup output also feeds the box's AC220 input on JP5.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eIn the box\u003c\/h3\u003e\n\u003cul class=\"crx-inc\"\u003e\n  \u003cli\u003e1 × FlexCore-ID-CB250A high-voltage control box, 1000 V\/250 A\u003c\/li\u003e\n  \u003cli\u003e1 × cover for the box and its cables\u003c\/li\u003e\n  \u003cli\u003e1 × 4G antenna\u003c\/li\u003e\n  \u003cli\u003e1 × Wi-Fi antenna, 2.4 GHz\u003c\/li\u003e\n  \u003cli\u003e1 × JP3 port plug, packed with the box\u003c\/li\u003e\n  \u003cli\u003e1 × JP4 port plug, pre-fitted, for parallel-cluster communication\u003c\/li\u003e\n  \u003cli\u003e1 × JP5 port plug, pre-fitted, for the AC input\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eBattery packs: three to thirteen per box\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eThe accessory kit, with the box-to-pack communication cable and main cluster leads\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eDC leads to the inverter (25 or 35 mm²) and the CAN cable\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eA Micro SIM, if the 4G link is used\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 class=\"crx-h\"\u003eOrder alongside\u003c\/h3\u003e\n\u003cul class=\"crx-need\"\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/sol-flexcore-id-bat20kwh\"\u003eSolis FlexCore-ID 20 kWh stackable battery\u003c\/a\u003e\n    \u003cp\u003eThe 20.09 kWh, 64 V LiFePO4 pack this box manages.
