Solar system for a house with evening backup power

House — a 4-hour power cut in the evening. The load is air conditioner ×2, fridge, lights & Wi-Fi, TV, washing machine and kitchen (microwave & kettle). It needs 9 kW of inverter and one LIO 4810 battery (4.8 kWh by name); the sizing tool names no single Voltronic inverter at that rating. Listings that state 9 kW or more in their own name start with the Axpert King IP52 10KW, Axpert MAX AIR 10K and InfiniSolar WP 10KW.

To carry 8 hours instead of 4, the same home has to store 8.5 kWh instead of 4.2 kWh — 13.5 kWh installed across 1 battery unit(s), 9.2 kWh more. The array stays at 5.6 kWp. Solar system for a house with overnight backup power

What the records of these units say

Motors set the inverter size, not the daily total: this profile uses about 25.4 kWh a day but reaches 8.1 kW in the instant its motors start. That calls for 9 kW, and the tool leaves the inverter as a rating here. Nearest by name: Axpert King IP52 10KW (AED 1,997), Axpert MAX AIR 10K (AED 1,997) and InfiniSolar WP 10KW (AED 1,997). Another route is two smaller units side by side: 63 inverter records in this catalogue state how many units run in parallel, up to 12.

The battery only has to bridge the outage: 4 hours of this load is about 4.2 kWh. The sizing covers that with one LIO 4810 battery (4.8 kWh by name), counting 4.3 kWh of it as usable. Its record states: nominal voltage 48VDC, cycle life “> 4500 @ 25°C” and 44.8 kg per unit. No inverter is named beside this pack, so its nominal voltage of 48 V is the figure to carry to the battery-voltage row of any inverter's page.

Panels are bought apart from this catalogue, which lists none; the array is therefore a count: 11 panels, 5.6 kWp, figured at 5.7 peak sun hours a day.

Voltronic parts beside the inverter and the battery

The first entries are the inverters named above; none of the rest is in the kit. 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

Which Voltronic inverter reaches the 9 kW this house needs?

The sizing tool names none, so the catalogue is read by name: Axpert King IP52 10KW at AED 1,997, Axpert MAX AIR 10K at AED 1,997 and InfiniSolar WP 10KW at AED 1,997. Open each one and compare its phase and battery-voltage rows with your site before ordering.

How much battery does this house kit hold?

One LIO 4810 battery (4.8 kWh by name); the sizing counts 4.3 kWh of that as usable against a need of 4.2 kWh. The pack's nominal voltage is 48VDC.

What is the price of the Voltronic units in this house kit?

1 × LIO 4810 at AED 2,844. 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.

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 11 of them, about 29 m² of roof.
