2. Product Information

2.1 General

The Volta 2K unit (hereinafter referred to as “Facility”) is a universal power supply that

can be used to power your appliances/devices when the main electricity power fails (i.e.

during load shedding). The changeover from grid to ‘back-up’ power occurs

automatically and requires no input from the user.

The Facility will be installed on the User’s premises by an accredited Stage Zero

Contractor. During the installation process, the user will inform the contractor which loads/

circuits should be powered during loadshedding. The selected essential loads will remain

powered in case of a power outage (load shedding).

The Facility consists of a packaged unit that has an integrated battery and inverter which

utilises grid power to charge the batteries during non-load shedding periods. The Facility

connects to the main AC circuit at a voltage of 230VAC (alternating current, single phase)

and converts it to low voltage DC (direct current) to charge the battery. The DC output

from the battery is then converted to a pure sinewave at 230VAC to supply the connected

essential load.

During outages, and if the Facility’s batteries are fully charged, uninterrupted power will

be delivered to the selected essential circuits. The Facility has a maximum output power

supply of 2kW and a battery capacity of 2560Wh (2304Wh @ DOD of 90%) and is capable

of sustaining a 900Wh load for approximately 2½ hours (e.g. x20 20W LED light bulbs, a

300W computer, a 60W laptop and a 140W home entertainment system).

During load shedding, the system will provide power to the selected circuits for a time

period dependant on:

• Load connected to the sub distribution board

• Whether the Facility’s battery was fully charged at the time when the power failed

(load shedding)

The Facility’s battery, under normal circumstances, should take approximately two to three

hours to fully charge from the point where they were completely discharged.

3 Operating Instructions

3.1 Operating Modes

The Facility has three operational modes. The modes are dependant on the position of the

Change Over switch.

Facility operational modes:

• The Change Over switch is in the ‘up’ position. The Facility’s back-up power

capability is bypassed enabling power supply solely from the grid, i.e. no back-up

power available.

• The Change Over switch is in the ‘neutral’ position. Independent of grid or back-

up power availability, the unit will not provide any power output.

• The Change Over switch is in the ‘down’ position. This is mode is the

intended operational mode, i.e. the unit is capable of supplying back-up power in case

of load shedding.

DO NOT
