Solar system for a farm with evening backup power
Farm profile, sized for a 4-hour outage after sunset. The load lands on the SPF 4000T DVM, a 4 kW SPF inverter whose record states a 48 V battery, with the ARK 2.5L battery, counted as 2.3 kWh.
The same battery (2.3 kWh installed across 1 unit(s)) covers 4 hours and 8 hours alike: 1.1 kWh needed here, 2.2 kWh there, both within it. The array stays at 1.5 kWp. Solar system for a farm with overnight backup power

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.
The battery is there for the outage: 4 hours of this profile come to 1.1 kWh. The sizing picks the ARK 2.5L: 2.56 kWh on the nameplate, counted as 2.3 kWh. Its record: Cobalt Free Lithium Iron Phosphate (LFP), 51.2 V nominal, 90% depth of discharge, IP65, 28 kg, wall-mounted or Floor installation.
On the roof side the kit needs 1.5 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.

How far can this storage grow?
The ARK 2.5L belongs to a line listed here in 10 sizes, 2.56–25.6 kWh.
Can a Growatt EV charger run beside this kit?
Yes, as a load of its own. The THOR 07AS-S/P-V1 takes a 230 V supply and charges at up to 7 kW (32 A); that is more than the 4 kW of inverter in this kit. The THOR 11AS-P-V1 needs 400 V. Work modes in its record: Fast/ PV Linkage/ Off-peak/ Load balancing. The sizing on this page does not count a charger.
