The Quote

Reference our meeting in which it was stated that a 6KW Solar Powered System is being planned for SUPARCO Lab. The system is designed to run the Lab for 8hrs a day in the following manner; i.e. It will act as a Main Power Supply system for the specified number of hours during office time. The system is also designed to add up more solar power in the future and room for further load to be attached to the system. The total peak load of the system is designed at approx 6000watts, although it can sustain a surge load of around 12000watts.

Scenario for Operating 6KW Output at SUPARCO SRDC Labs This solution not only gives assurance that whole system works smoothly but also that required appliances can be used as they were working on grid electricity with True Sine Wave frequency. This quotation covers the installed appliances running independently on Solar Power, usage of appliances in hours has also been considered in order to optimize the system:

The quotation is engineered using the following hardware:
