That headroom suits today's high-current, large-format panels. Strings on the same tracker should be identical. The trackers run from 90 V to 435 V, start-up is 90 V, and the open-circuit voltage must stay below 500 V on the coldest day.\u003c\/p\u003e\n\u003cp\u003eFull output needs only 186 V of string voltage, the bottom of the full-load MPPT range.

For full battery power, run two or more in parallel through a combiner box.\u003c\/p\u003e\n\u003cp\u003eSolis recommends a 300 A DC breaker between the battery and the inverter. Inverters made before April 2026 need a Solis firmware update before commissioning with an IntelliHome, and the \"No battery\" setting lets it start out as a grid-tied inverter.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eBackup, generator and off-grid\u003c\/h3\u003e\n\u003cp\u003eThe backup port gives 10 kW continuously and up to 20 kW for 10 seconds, plenty for motor and compressor starts.
