Off-grid solar system for a villa
Villa profile, for a site the grid does not reach. The load lands on the SPF 12000T DVM, a 12 kW SPF inverter whose record states a 48 V battery, with 2 × AXE 50.0L batteries, counted as 90 kWh.

Where this kit sits in the Growatt range
The SPF 12000T DVM is rated 12 kW and its record gives a surge rating of 36 kW; this profile peaks at 11.7 kW when its motors start. Its record states a 48 V battery (Lithium/Lead-acid). Transfer time in the record: 10ms(max). The enclosure is IP20 and the unit weighs 75 kg.
Off the grid, the battery has to hold a whole day of this profile: 49.5 kWh. The sizing picks 2 × AXE 50.0L: 100 kWh on the nameplate, counted as 90 kWh. Its record: Cobalt free lithium iron phosphate (LFP), 51.2 V nominal, 92% depth of discharge, IP20, 402 kg, floor installation.
On the roof side the kit needs 11.6 kWp: 22 panels, about 57 m², with 5.7 hours of full sun a day assumed. The SPF 12000T DVM's record sets 14,000 W as the most panel power it takes, and this array stays under it. Its tracker works between 60 and 145 V, and 150 V is the DC ceiling the strings must stay under. The panels themselves are not Growatt products here.
