Solar system for an office with overnight backup power
Office profile, sized for 8 hours of night with the grid down. The load lands on the SPH 10000TL-HU, a 10 kW single-phase SPH hybrid, with the ARK 25.6L battery, counted as 23 kWh.
If 4 hours are enough instead of 8, the storage needed falls to 6.7 kWh — 11.5 kWh installed across 1 battery unit(s), 11.5 kWh less. The array stays at 8.9 kWp. Solar system for an office with evening backup power

Where this kit sits in the Growatt range
The SPH 10000TL-HU is a single-phase hybrid: 10,000 W of AC output, against a starting peak of 9.2 kW in this profile. Its battery side works at 40–60 V, up to 200 A in charge or discharge, and the record lists Lithium / Lead-acid as battery types. The enclosure is IP65 and the unit weighs 48.84 kg.
The battery is there for the outage: 8 hours of this profile come to 13.5 kWh. The sizing picks the ARK 25.6L: 25.6 kWh on the nameplate, counted as 23 kWh. Its record: Cobalt Free Lithium Iron Phosphate (LFP), 51.2 V nominal, 90% depth of discharge, IP65, 280 kg, wall-mounted or Floor installation. That 51.2 V sits inside the 40–60 V battery range the SPH 10000TL-HU states.
On the roof side the kit needs 8.9 kWp: 17 panels, about 44 m², with 5.7 hours of full sun a day assumed. The SPH 10000TL-HU's record sets 15,000 W as the most panel power it takes, and this array stays under it. Its tracker works between 150 and 450 V, and 525 V is the DC ceiling the strings must stay under. The panels themselves are not Growatt products here.

Frequently asked questions
What does the office profile switch on?
3 × air conditioner, 2 × lights & Wi-Fi, 4 × computers and kitchen (microwave & kettle). Together they peak at 9.2 kW and use 40.4 kWh a day; the inverter and the storage are sized from those two figures.
Does the ARK 25.6L match the SPH 10000TL-HU?
By their records, yes: the ARK 25.6L is 51.2 V nominal, inside the 40–60 V battery range the SPH 10000TL-HU states.
What do the Growatt units of this kit come to?
SPH 10000TL-HU: AED 4,790, ARK 25.6L: AED 13,153 — AED 17,943 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 ARK 25.6L belongs to a line listed here in 10 sizes, 2.56–25.6 kWh. The SPH 10000TL-HU's record allows 6 units stacked.
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 70% of the 10 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.
