Solar system for a villa with overnight backup power
Villa profile, sized for 8 hours of night with the grid down. The load lands on the SPF 12000T DVM, a 12 kW SPF inverter whose record states a 48 V battery, with the ALP35.0L-E2 battery, counted as 31.5 kWh.
If 4 hours are enough instead of 8, the storage needed falls to 8.3 kWh — 16.1 kWh installed across 1 battery unit(s), 15.4 kWh less. The array stays at 10.9 kWp. Solar system for a villa with evening backup power

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.
The battery is there for the outage: 8 hours of this profile come to 16.5 kWh. The sizing picks the ALP35.0L-E2: 35 kWh on the nameplate, counted as 31.5 kWh. Its record: Cobalt Free Lithium Iron Phosphate (LFP), 51.2 V nominal, 92% depth of discharge, IP66, 308 kg, floor/Wall mount.
On the roof side the kit needs 10.9 kWp: 20 panels, about 52 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.

Frequently asked questions
What does the villa profile switch on?
4 × air conditioner, fridge, freezer, 2 × lights & Wi-Fi, 2 × TV, washing machine, water pump and kitchen (microwave & kettle). Together they peak at 11.7 kW and use 49.5 kWh a day; the inverter and the storage are sized from those two figures.
Does the ALP35.0L-E2 match the SPF 12000T DVM?
The SPF 12000T DVM's record states a 48 V battery (Lithium/Lead-acid); the ALP35.0L-E2's states a nominal 51.2 V.
What do the Growatt units of this kit come to?
SPF 12000T DVM: AED 5,251, ALP35.0L-E2: AED 17,983 — AED 23,234 together. Each figure is the one on its product page, and the order is collected from our store in Dubai or Riyadh.
How far can this storage grow?
The ALP35.0L-E2 belongs to a line listed here in 8 sizes, 5–40 kWh. Its record on parallel use: Max. 8 PACKs in parallel (Max. 8 clusters in parallel).
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 58% of the 12 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.
