Where this kit sits in the Growatt range
The SPF 4000T DVM is rated 4 kW and its record gives a surge rating of 12 kW; this profile peaks at 3.9 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 42 kg.
Off the grid, the battery has to hold a whole day of this profile: 6.7 kWh. The sizing picks the ARK 12.8L: 12.8 kWh on the nameplate, counted as 11.5 kWh. Its record: Cobalt Free Lithium Iron Phosphate (LFP), 51.2 V nominal, 90% depth of discharge, IP65, 140 kg, wall-mounted or Floor installation.
On the roof side the kit needs 1.6 kWp: 3 panels, about 8 m², with 5.7 hours of full sun a day assumed. The SPF 4000T DVM's record sets 5,000 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.
