Always confirm compatibility against the current Solis approved battery list before specifying a system, given the high voltage architecture.\u003c\/p\u003e\n      \u003c\/details\u003e\n\n      \u003cdetails style=\"padding:10px 0; border-bottom:1px solid #eee;\"\u003e\n        \u003csummary style=\"cursor:pointer; font-weight:bold; color:#008377CF;\"\u003eHow fast is the backup power switchover?\u003c\/summary\u003e\n        \u003cp style=\"margin:8px 0 0;\"\u003eThe manufacturer's datasheet specifies a switchover time of \u003cstrong\u003eunder 10ms\u003c\/strong\u003e, allowing critical loads on the backup ports to continue running through most grid outages with minimal interruption.\u003c\/p\u003e\n      \u003c\/details\u003e\n\n      \u003cdetails style=\"padding:10px 0; border-bottom:1px solid #eee;\"\u003e\n        \u003csummary style=\"cursor:pointer; font-weight:bold; color:#008377CF;\"\u003eCan this inverter be used with a backup generator?\u003c\/summary\u003e\n        \u003cp style=\"margin:8px 0 0;\"\u003eYes. It includes a \u003cstrong\u003ededicated generator input rated at 20kW\u003c\/strong\u003e, with built-in AC voltage detection of both grid and generator output to prevent reverse current from damaging the generator during extended outages.\u003c\/p\u003e\n      \u003c\/details\u003e\n\n      \u003cdetails style=\"padding:10px 0; border-bottom:1px solid #eee;\"\u003e\n        \u003csummary style=\"cursor:pointer; font-weight:bold; color:#008377CF;\"\u003eWhat is the surge power rating in backup mode?\u003c\/summary\u003e\n        \u003cp style=\"margin:8px 0 0;\"\u003eThe 20kW model is rated for \u003cstrong\u003e1.6 times rated power for 10 seconds\u003c\/strong\u003e in backup mode. This is lower than the surge rating on the 12K and 15K models in the same range, which are rated at 2 times, so motor-starting loads should be checked against this figure specifically.\u003c\/p\u003e\n      \u003c\/details\u003e\n\n      \u003cdetails style=\"padding:10px 0;\"\u003e\n        \u003csummary style=\"cursor:pointer; font-weight:bold; color:#008377CF;\"\u003eDoes this inverter support UK grid connection standards?\u003c\/summary\u003e\n        \u003cp style=\"margin:8px 0 0;\"\u003eYes, the series is certified to \u003cstrong\u003eG99\u003c\/strong\u003e under the manufacturer's listed grid connection standards.
