Back-Up System

Charged from the Grid to only provide power supply to essential equipment.

This system is designed to provide back-up power when the grid fails or is not available
for prolong periods and will also protect sensitive electrical apparatus from surges and transient that may damage this equipment.

A back-up system consists of an Inverter connected to a battery pack, which is charge by the grid by means of the inverter or dedicated battery charger. The essential load/s is connected to the inverter which will provide the back-up power during the outage.

To add to the flexibility of the system, PV array can be added to charge the batteries by means of a Solar Charge controller or the system can be integrated with a Grid Tied System to increase the back-up period for the essential equipment in the property.

Back-Up Power

Back-Up Power can be provided in case of Grid Failure

9

Power is Always Available

Power is always available for the Essential Equipment, provided the battery capacity is sufficient to provide back-up for the period when sun energy is not available.

9

No Surges

No surges of transients will harm electrical appliances if correct type of Surge protection is used and installed on the PV array and AC Supplies

9

Tax Deductible

The system is tax-deductible and savings is directly related to the annual increase of Eskom – this year was 15% compare to the interest of savings account around 11% only.

Disadvantages

Disadvantage:

Back-Up Systems

9

Large Investment

The system requires large capital investments.

9

Battery Maintenance

If lead acid batteries require lots of maintenance but for Lithium less to low maintenance is required.

9

Extra Appliances Needed

If a generator, PV Array or Grid is not available to charge the batteries, power generation is not possible during periods when no sun is available
