Back-Up Power

Back Up Power Systems – For City Locations Where Utility Power Is Unreliable

Back-up power systems present a successful solution as an alternative energy source in areas where the utility power is unreliable or unavailable. These systems are designed to operate just like the conventional Un-interruptible Power Supplies (UPS) with the difference in the type of loads that they can run and the duration of the back up time. (These units will run most loads including – air conditioners, refrigerators, pressing irons, kettles, water heaters, computers, telecommunications equipment, fans, microwave ovens, lighting fixtures and most household and office loads for as long as required
– up to 24 hours daily).

They depend entirely on power from the utility grid (NEPA now PHCN) or the generator set to recharge the battery bank. This system is designed to be dependent on the national grid (PHCN) and/or genset. Economics play a big part of the final decision on which type of power system to deploy for
your installation.

STAND-ALONE PACKAGES – Although the solar electric system might be the most economical choice in the life cycle cost analysis, it requires a considerable amount of initial investment.

HYBRID PACKAGES – The substantial part of the generator systems cost is the long-term maintenance and is an important factor when ensuring system performance over the lifetime of the design. With the hybrid package the two power sources are combined together to lower the initial investment capital of the solar system and to lower the operating and maintenance costs of the generator power systems.

However, with the BACK UP POWER PACKAGE, the solar modules and all associated equipment are eliminated and the battery bank is being charged solely with available power from the genset and/or the national grid.
