It powers the home from the panels first, stores the surplus in the battery, and switches the backup circuit to battery power in under 10 ms when the grid goes down.\u003c\/p\u003e\n\u003cp class=\"crx-lede\"\u003eIts rated output is 5 kW, 21.8 A at 230 V, which is above the 16 A that G98 allows, so the network operator has to approve a G99 application before it is fitted.

Tracking runs from 90 V to 435 V with start-up at 90 V, and the inputs must never see more than 500 V, which a long string of modern panels can exceed on a frosty morning: check the cold open-circuit voltage before settling the string length.\u003c\/p\u003e\n\u003cp\u003eKeep the two PV numbers separate. \u003cb\u003e10 kWp\u003c\/b\u003e is Solis's recommended maximum array, twice the 5 kW rating. \u003cb\u003e8 kW\u003c\/b\u003e is the most PV power the 5 kW will take in at any moment, 160% of its rating, and the rest is clipped. Because each input stops at 16 A, a string must work at 250 V or more to deliver that full 8 kW. An east\/west layout, one roof face per tracker, gives a flatter output curve that loses little to the cap.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eThe battery side\u003c\/h3\u003e\n\u003cp\u003eAny 40–60 V lithium or lead-acid battery can be used, with BMS communication over CAN or RS485. The 5 kW charges and discharges at up to 5 kW and 112 A, which is more than one IntelliHome 5 kWh's 100 A rating, so with a single 5 kWh the battery sets the limit. The IntelliHome 10 kWh (200 A) or 16 kWh (157 A), or two 5 kWh units in parallel, cover the full 112 A.\u003c\/p\u003e\n\u003cp\u003eInverters built before April 2026 need Solis's firmware update before they are commissioned with an IntelliHome battery. There is also a \"No battery\" mode, so the 5 kW can run as a grid-tied inverter until a battery is added.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eBackup, generator and off-grid\u003c\/h3\u003e\n\u003cp\u003eThe backup port supplies the full 5 kW continuously, and up to 10 kW for 10 seconds to start motors and compressors. When the grid is up, up to 40 A passes through to the backup loads; in a power cut they share the inverter's 5 kW.\u003c\/p\u003e\n\u003cp\u003eThere is a GEN port for a generator, with automatic on\/off control, and the inverter can run off-grid from solar alone. Existing grid-tied solar can be AC-coupled for export control and off-grid operation, and up to six of these inverters can run in parallel, including three-phase arrangements of three or more.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eGrid approval\u003c\/h3\u003e\n\u003cdiv class=\"crx-note\"\u003e\n  \u003cdiv\u003e\n    \u003cb\u003eG99: approval before installation\u003c\/b\u003e\n    \u003cp\u003eThe 5 kW's 21.8 A is over G98's 16 A per phase, so the installer applies to the network operator under G99 and waits for approval before fitting it.
