Solar system for an apartment with overnight backup power
Apartment — 8 hours of night with the utility down. The load is air conditioner, fridge, lights & Wi-Fi, TV and washing machine. From the Voltronic catalogue the sizing takes the InfiniSolar V III TWIN 6.2KW inverter and 2 × LIO 4810 batteries (4.8 kWh each by name).
If 4 hours are enough instead of 8, the storage needed falls to 2.3 kWh — 4.3 kWh installed across 1 battery unit(s), 4.3 kWh less. The array stays at 3 kWp. Solar system for an apartment with evening backup power

The inverter in this system is a 120 V-class (split-phase) model, the only one in the catalogue that fits this load. Mains here is normally 230/400 V, so check your supply voltage before ordering.
What the records of these units say
Motors set the inverter size, not the daily total: this profile uses about 13.8 kWh a day but reaches 4.9 kW in the instant its motors start. The InfiniSolar V III TWIN 6.2KW is the unit the sizing landed on; its record gives the rated output power as “6200W”. The sizing marks this unit for a supply check, and these are the rows it turns on: the record gives the acceptable input voltage as “80-130 VAC/80-150VAC” and the nominal output voltage as “101/110/120/127 VAC 208/220/230/240 VAC”. If the load grows, the same record allows up to 9 units in parallel.
The battery only has to bridge the outage: 8 hours of this load is about 4.6 kWh. The sizing covers that with 2 × LIO 4810 batteries (4.8 kWh each by name), counting 8.6 kWh of it as usable. Its record states: nominal voltage 48VDC, cycle life “> 4500 @ 25°C” and 44.8 kg per unit. Two rows to hold against each other before ordering: the InfiniSolar V III TWIN 6.2KW states a battery voltage of 48 VDC in its record, and this pack states 48 V nominal in its own.
Panels are bought apart from this catalogue, which lists none; the array is therefore a count: 6 panels, 3 kWp, figured at 5.7 peak sun hours a day. What the InfiniSolar V III TWIN 6.2KW accepts on its solar input, from its record: maximum PV power “8000W” and MPP voltage range “120 VDC ~ 430 VDC”. String the panels inside those limits.
Voltronic parts beside the inverter and the battery
None of these is in the kit above. Each is its own listing, with its own table and its own price, for the site that needs a transfer switch, remote monitoring or a separate charge controller.

Frequently asked questions
What does the InfiniSolar V III TWIN 6.2KW do when the power cuts?
The catalogue files it as “On-Grid with Energy Storage”. In this kit it carries the load from the battery for the 8 hours sized here, about 4.6 kWh.
How much battery does this apartment kit hold?
2 × LIO 4810 batteries (4.8 kWh each by name); the sizing counts 8.6 kWh of that as usable against a need of 4.6 kWh. The pack's nominal voltage is 48VDC, and the inverter's record states a battery voltage of 48 VDC.
What is the price of the Voltronic units in this apartment kit?
1 × InfiniSolar V III TWIN 6.2KW at AED 1,438 and 2 × LIO 4810 at AED 2,844, AED 7,126 in all. That is the figure on each product page and the one you pay when you collect the order from our store in Dubai or Riyadh; panels and installation are outside it.
Can a second InfiniSolar V III TWIN 6.2KW be added later?
Its record states parallel operation of up to 9 units, so the inverter side can grow without replacing the first unit. Battery capacity is a separate decision, taken from the battery's own record.
Does Voltronic supply the solar panels as well?
Not in this catalogue. It lists 233 inverters, 88 UPS, 16 batteries, 20 solar charge controllers and 17 voltage regulators, and no panels. This kit needs 6 of them, about 16 m² of roof.
