Up to now, we were all forced to use power for a central electricity grid, as there were no alternatives. But this has several disadvantages….
Some turn to generators for backup power solutions, but generator have several disadvantages
The perfect backup power and solar power solution for your home, home office or small business…
The starting point is the PV system: during normal operation, one or more Sunny Boys feed the solar power generated by the PV system into the public grid, with high efficiency.
Only in the event of a grid fault or failure does the Sunny Backup system become active. The switching device disconnects the PV system and the loads from the grid in compliance with the appropriate standard.
While the system is switched to the domestic grid, the battery continues the loads’ power supply after
just 20 milliseconds. And the Sunny Backup 5000 functions as a “system manager”, coordinating all switching operations such as disconnection from
the grid, and transfer to the PV system, for example. Thus, every grid failure is compensated reliably
In parallel to this, the PV system acts as energy source for the direct supply of loads, and for battery charging. Due to the integration of the PV system, a small and therefore low-cost battery can be implemented, as it is usually only needed to bridge the night hours.
With this combination of PV system and battery, the loads can be supplied with energy over long periods of operation, even in the event of a power outage. One of the prerequisites for this is consistent use of AC coupling in order to enable smooth interplay between the Sunny Backup and the solar inverters.
A hybrid power system combines a solar power system with backup power. A grid-tied solar power system is dependant on the power grid to operate. If there is a power failure the solar system stops working. But with a hybrid power system, the Batteries and battery inverter will simulate a “local grid” for the grid tie inverter. Thus ensuring that there is always a grid available for the grid-tied inverter to work…
Grid-tied solar systems, depend on a grid being present for it to work. If there is no grid for example during load shedding the solar system also stops working. Having a backup power system in place, allows the solar system to continue working, even if there is a grid power failure. This is achieved by the backup power inverter simulating a local grid for the grid tied inverter.
Our backup power solutions easily integrate with your existing DB Board.
We recommend that a new DB board be installed that is dedicated for backup power circuits.
An extra earth leakage protection switch is installed in this new DB board.
Then certain existing circuits can be moved over to the new “backup power DB Board”.
Alternatively extra plugs can be installed in addition to the existing plugs.
There could be, depending on your installation. We will do a site assessment before installation begins, and notify you of this. Some extra cost can be involved for

Price above is valid for all installation with the following criteria:
Any additional, time, travel or material will be at an additional cost.
Additional time might be required to sort out potential electrical earth faults or, to do any required rewiring of circuits.
Additional time is charged at R 450 per hour.
Additional travel is charged at R 4.00 per km.
