Please respond only after reading in entirety & understanding the description. Need 38 W at 24VDC & 58W at 120VAC power. The location for this plant will be in 36.794556, -118.899506 MS bing co-ordinates in Seqouia National forest, Fresno County, CA, USA. The facility needs to be 24x7x365 operation, so please keep that in mind in your design. A generator is available to charge the batteries under adverse conditions when the batteries get too low. The generator is 14KVA 480V Delta connected to a 15KVA 208V Wye transformer. Please help design the HW for this as a complete Bill of Materials. Use HW from reputed manufacturers with some reasonable history. The inverter/controller must have communications port for real-time operational, status & diagnostics data, with a known protocol. Also quote separately for building the system, witnessed testing, delivery to site (if you can). Or connect with someone who can help build one & deliver to USA. Please ask any questions as this will be an evolution based state of the art system design. We do not have any budgetary constraints defined at the moment. Please share some relevant samples with your response. Please submit any questions with your response to cut any delays. Any work done under this job will be provided to us with no strings attached & will become our property. We expect your response within a few days of award.

Hi, Your project is very interesting and I am very keen to work on this project. I am an electrical design engineer with 6 years of experience on EPC projects. Recently, I have provided 56 solar power systems to our client ADNOC (U.A.E) for remote oil and gas wells. Those solar power systems have similar specifications. They are completely stand alone systems designed for 24/7 operation and they have 3 days battery back up. We also provided generator charging option in all systems in case no sun appear for more than 3 days. All solar power systems are connected to central monitoring system via remote terminal unit and wireless / fiber optic telecom system. So, I have practically designed, installed, tested and commissioned the same systems for our client (ADNOC) in U.A.E. I have all design information, sub-vendors and manufacturers information as well as fully aware of latest available technologies in the market and I will provide you optimum and start of the art design according to your need. Moreover, I believe that your project is a good chance to connect with people in U.S.A and build long term relationship. Following is the cost breakdown of my quote:- 1. Design and Documentation - 675 USD. 2. Procurement and assembling - As per actual after detailed design. 3. Witness Testing - (150 USD per day + air ticket, accomodation). 4. Delivery to site - As per actual based on selected manufacturers' location. Looking forward for further hearing from you. Regards Talha

I can design your solar power system to operate based on your specific power requirements and in conjunction with your on site generator. I can also select the solar inverter and monitoring equipment. I will contact a solar power contractor in San Francisco to request for a quote based on my design. If I can not receive a quote from a local contractor I will provide you with a project estimate that will be within ten percent of the average market cost for the installation. I can produce the design in AutoCAD, select PDFs of the necessary equipment and if necessary the estimate will be in excel. I have 20 years of experience in electrical engineering in the United States and around world. I have completed several solar power projects with in this past year. You can see examples of my work here https://www.freelancer.com/u/ProjexConsultant Please contact me to discuss details. i look forward to working together.

Hi there, I have check you proposal carefully and my team can help you with the development, few questions that I have so far: 1)The facility needs to be 24x7x365 - is it in mm? 7 mm is too small, we will need 25-30 mm, if it's in inches - works 2) Should it work from battery? along with power from the 208VAC generator Approximate estimation for PCB design, BOM, schematics around 100h of work with hourly rate 30$ When it's ready we can move forward with prototype and firmware Let me know your thoughts Thanks
