Strings sharing a tracker should match in panel count and orientation. The MPPT range is 90–435 V with start-up at 90 V, and no string may exceed 500 V open-circuit, even on the coldest morning.\u003c\/p\u003e\n\u003cp\u003eWith 32 A per tracker, the full-load MPPT range starts at just 200 V, so shorter strings still deliver the full output. Two figures set the array size: \u003cb\u003e16 kWp\u003c\/b\u003e is Solis's recommended maximum, twice the 8 kW rating, and \u003cb\u003e12.8 kW\u003c\/b\u003e is the most PV power it uses at once, 160% of the rating, with the rest clipped. A large array split across east and west faces suits that cap well, as the two halves peak at different times of day.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eThe battery side\u003c\/h3\u003e\n\u003cp\u003eIt accepts any 40–60 V lithium or lead-acid battery, with BMS communication over CAN or RS485, and charges and discharges at up to 8 kW and 190 A. A single IntelliHome 10 kWh, rated 200 A, covers that in full; the 16 kWh is rated 157 A and the 5 kWh 100 A, so with those the battery sets the limit unless more units are paralleled.\u003c\/p\u003e\n\u003cp\u003eThe battery cables are heavier than on the 3 to 6 kW models, and Solis recommends a 300 A DC breaker on the battery side. Inverters built before April 2026 need Solis's firmware update before commissioning with an IntelliHome, and with no battery fitted the \"No battery\" setting runs it as a grid-tied solar inverter.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eBackup, generator and off-grid\u003c\/h3\u003e\n\u003cp\u003eBackup delivers 8 kW continuously and twice that for 10 seconds. While the grid is connected, up to 50 A can pass through to the backup circuit; in a power cut, the backup loads have to fit within 8 kW.\u003c\/p\u003e\n\u003cp\u003eA generator connects with automatic on\/off control, the inverter can run off-grid from solar alone, and existing grid-tied PV can be coupled in for export control.
