Solis recommends charging and discharging at 157 A, a 0.5P rate, which rates a three-pack cluster at about 30 kW DC and a thirteen-pack cluster at about 130 kW.\u003c\/p\u003e\n\u003cp\u003eThe control box forms the top layer of one column. Three or four packs make a single column, five to nine are split across two, and ten to thirteen spread over three. Bases sit 100 mm apart, the minimum Solis gives for heat to escape between rows.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eParallel clusters and the inverter\u003c\/h3\u003e\n\u003cp\u003eWhere one cluster is not enough, the datasheet allows six in parallel, taking a site past 1.5 MWh. Each cluster keeps its own control box, chained box to box on the DC side.\u003c\/p\u003e\n\u003cp\u003eThe FlexCore datasheet sets the battery beside Solis S6-EH3P three-phase hybrids from 30 kW to 125 kW at 230\/400 V. Their battery windows differ, 150–800 V on the 30–60 kW models and 300–950 V on the 80–125 kW ones, so confirm the pack count for the chosen inverter with Solis before ordering.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eFire protection and the room it needs\u003c\/h3\u003e\n\u003cp\u003eFire suppression is built into each pack as an aerosol unit. The manual still treats the room as part of the safety design: indoors only, in a fireproof room free of ignition sources, with its own fire alarm and extinguishing equipment. The floor has to be dry, level and able to carry the full weight of the stack.\u003c\/p\u003e\n\u003cp\u003eA single cluster wants 500 mm clear above it, 600 mm at the front and right-hand side, and 100 mm behind. Ambient limits are −20 to 55 °C discharging and 0 to 55 °C charging, and with fan noise rated below 75 dB, a plant room suits it better than an office.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eHandling a 154 kg pack\u003c\/h3\u003e\n\u003cp\u003eAt 154 kg, a pack is a job for lifting equipment rather than hands. Solis has the installer hook all four corners and stack the packs layer by layer, four bolts each. The manual names no particular lifting tool, leaving it to be sourced for the site; its tool list includes a hydraulic lifting cart, and it calls for at least four installers.\u003c\/p\u003e\n\u003cp\u003eOnce packs are installed, the rack is not to be moved or lifted. Solis also asks for commissioning no later than six months after the system arrives, and for stored packs to be recharged every three to six months.\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-BAT20kWh battery pack, 20.096 kWh\u003c\/li\u003e\n  \u003cli\u003e1 × front panel, marked optional in the packing list\u003c\/li\u003e\n  \u003cli\u003e1 × inter-pack communication cable, 145 mm\u003c\/li\u003e\n  \u003cli\u003e1 × inter-pack power cable, 330 mm\u003c\/li\u003e\n  \u003cli\u003e1 × earth wire, 250 mm\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eThe high-voltage control box: one per cluster, sold separately\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eBases, feet, main cluster leads and terminating plug: in the accessory kit\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eDC leads from the control box to the inverter, made up on site\u003c\/li\u003e\n  \u003cli class=\"crx-no\"\u003eLifting hooks or other lifting gear\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-cb250a\"\u003eSolis FlexCore-ID battery control box\u003c\/a\u003e\n    \u003cp\u003eThe 250 A high-voltage box that heads every cluster and talks to the inverter over CAN.
